Introduction

Crease Matic Auto 50
Designed and manufactured in the U.K., the new Crease Matic Auto 50 is a fully programmable high speed card creaser. Documents are suction fed and creased at up to 7000 sheets per hour. It is possible to crease Digital and Litho printed card, removing cracking that may occur at the folding stage.
The CM Auto 50 is capable of accommodating stock from CD-SRA2 (500x700mm), with a capability to program a maximum of 29 creases per sheet anywhere along its length.
A maximum of 99 different jobs can be programmed and saved to the machines internal memory, making the selection and recall of common jobs quick and easy.
Jobs are programmed in Absolute mode. All crease positions are measured from the leading edge and entered directly. Incremental mode may be used to make image shift adjustments with one alteration.
The machine is supplied with rotary perforation that is adjustable across the width of the document, and four widths of slide-out and turn crease matrix as standard.

Machine Components

When installing the machine the supplied power cable should be plugged into the switched power socket on the machine and then to the power supply socket. Switch the machine on and the control screen will initialize. The compressor/vacuum unit has a separate on/off switch located under the Choke Control Wheel. This allows the unit to be switched off when not in use.

Setting Side Lays
There are two side lays on the machine which sit at each side of the paper on the infeed section. Their purpose is to guide the paper under the feed gate and into the feed rolls accurately, to ensure a square crease is made across the document. They also supply air to the underside of the paper stack, by way of thin slots, in order to make the paper “float” before the bottom sheet is vacuum fed away under the feed gate. On the CM Auto 50 there is also the capability to adjust the lays out of squareness to accommodate for non square crease lines, although this adjustment is minimal.
Firstly, ensure that the squareness adjustment is set to its central position by aligning the two marks on the machine bed.
The right hand side lay has four location positions. By releasing the thumbscrews at the feed gate end, the lay may be extracted from one slot and repositioned in another, using the thumbscrew to secure it. This position must be selected with the paper size being fed in mind, in order to keep the feed gate as central as possible to the paper centre line.
Once the right hand lay is in position, loosen the two thumbscrews at either end of the left hand side lay and with a single sheet in the machine, push it across to the correct width of document. The lays should not pinch the document and the paper must sit on top of the protruding edge at the base of the lay. Secure the thumbscrews when in position.

Setting Side Lays cont.
Air flow to the slots is controlled using the thumbscrews running along the top edge of each lay. By screwing them down (clockwise) all the way the flow of air will be stopped. This should be done if the document does not cover the slots. Screwing them up will allow air to pass through the slot. The thumbscrews are fitted with anti-vibration devices, to prevent the settings from altering during normal operation. After placing the paper onto the machine, the magnetic backstop should be placed behind the stack to prevent it from moving.

Setting Outfeed Tray

Thumbscrews
Magnetic Side Lays
Bottom Stop Plate
The outfeed tray has two thumbscrews , one on each side. By loosening the thumbscrews the bottom stop plate may be extended to allow larger sheets to be collected without damage.
The magnetic side plates may be positioned to keep fed documents stacked accurately.
The outfeed tray can be removed in order to adjust the lower perforation wheel shaft.

Changing Crease Matrix

The machine is supplied with two crease matrix bars that have different widths of slot on either side. One of these slots allows the operator to use replaceable self adhesive matrix bars, the other three may be changed depending on the thickness of the material to be creased.
The bar must only be changed while the machine is in its rest position with the knife at its highest point. Withdraw the bar from the slot, turn or replace with the correct size slot, and slid the bar into the machine until it stops.

Choke Adjustment and Rotating Cylinder

The choke is used to control the amount of vacuum applied to the front edge of the paper through the rotating cylinder holes. The amount of vacuum needed is dependant on the type of paper being fed. Thin gauge paper, 80gsm to 90gsm will tend to wrap around the cylinder easier than thick gauge paper, and will need less vacuum to feed. By rotating the choke control wheel clockwise, more area of slot inside the cylinder is exposed through the holes and so more of the front edge of the document is sucked onto the wheel.

Feed Gate Adjustment
The feed gate is set to allow only one document past at a time. This is achieved by altering the gap and position of the bottom edge of the gate to the rotating cylinder. There are two thumbscrew adjustments. One on top, to allow the vertical movement of the gate, and one under the top cover, to allow horizontal movement. Adjustment of the gate carried out along with adjustment of the choke.

Horizontal Adjustment

Firstly, set the choke to the correct position for the thickness of document about to be fed. Then, using the smaller thumbscrew, align the front face of the feed gate to the left hand edge of the choke slot, seen inside the rotating drum.
Front Face

Vertical Adjustment

The vertical adjustment is used to achieve the correct gap between drum and feed gate dependant on paper thickness being fed. Place a stack of paper onto the machine feed table. With the machine and compressor turned on, adjust the vertical thumbscrew until only one document is taken from the base of the stack at a time.

Perforation Wheels

Top Wheel
Control Wheels
Spring
Bottom Wheel
The perforation wheels are located under the top cover of the machine. The outfeed tray may be lifted clear of the machine in order to gain access to the lower shaft. By altering the position of the wheels along their shafts, perforations can be made at any point across the documents width. You can use the perforation wheels without needing to crease the documents. There are also feed wheels on these shafts, and it may be necessary to alter their positions to achieve the correct perforation position. To perform perforations away from the centre of the paper, the order of the feed wheels and perforation wheels on the shaft must be changed to maintain drive across the width of the document.
Location Holes
Sprung Locator
Top Shaft and Collar
The wheels may be raised or lowered using the sprung locator to the left end of the top shaft. Two location holes allow easy positioning of the shaft in either the up or down position. The shaft must be in its up position to make any alterations to the perforation position. When lowering the top shaft, the perforation wheel must be pulled against the spring until it is located, so that the wheels are in contact when the spring is released.

Top Shaft Alterations

Top Shaft and Perforation Wheel
The top shaft must be in its raised position to be removed. It is removed by undoing the grub screw in the collar on the left hand end and sliding the collar to the right and out of the bush, allowing the end of the shaft to come towards you. It can then be removed from its location on the right hand side. The components on the shaft can then be loosened, slide off and repositioned in the desired order.
Note. The perforation wheel is positioned between two drive wheels and is sprung loaded. This arrangement must stay the same wherever you position the perforation wheel along the shaft.
All screws should be tightened onto the machined flat so that the shaft is not damaged. Refitting is the opposite of removing. Locate the right hand end of the shaft in the bush on the right side of the machine, line up the left hand side and slide the collar into the bush. Tighten the screw to secure. Accurate setting of this wheel can only be achieved when a test document is run, and final adjustments to measurements should be made at this stage.

Bottom Shaft Alterations

Collar and Grub Screw
The bottom shaft can not be removed from the machine but can be slid across to allow components to be removed and repositioned.
Note. The drive wheels on the bottom shaft must stay in line with the wheels on the top shaft.
Bottom Shaft
Collar and Gap
Undo the grub screw in the collar on the left hand end of the shaft. Slide the shaft to the right until there is a big enough gap near the collar to remove the drive wheels. Reposition the desired components opposite the wheels on the top shaft and tighten in position. Slide the shaft back into the collar and tighten the grub screw onto the flat. Accurate adjustments and alignment may be made with the top shaft down.

Compressor/Vacuum Controls

Where the compressor/vacuum unit has two controls. The right hand control wheel increases and decreases the supply of air to the machines side lays. The left hand control alters the amount of vacuum supplied to the choke. This may need to be decreased when using light or thin paper.
If the compressor/vacuum unit is not fitted with air flow controls, the volume of air delivered to the paper stack may be reduced by opening the uncovered air flow controls in the side lay.

Absolute and Incremental Programming
t
d
The main difference between the two types of programming system is that Absolute measurements are taken from the leading edge of the document, and Incremental measurements are taken from the previous crease line.
The machine is not meant to be programmed initially in Incremental mode! It is intended that the initial program should be entered in Absolute. I.e. all measurements are taken from the leading edge. Then if an adjustment is required because the print registration has changed to the leading edge, select “Incremental”, then enter program mode and any change to any crease position will also affect any following crease positions by the same amount.
Example.
A document requires three creases, the first is 100mm from the leading edge, the second is 150mm from the leading edge and the third is 175mm from the leading edge as shown below.

To program this job in Absolute, all of the measurements are taken from the front edge,
1st crease at 100mm 2nd crease at 150mm 3rd crease at 175mm
To program with Incremental measurements, the first distance is taken from the front edge, the second is taken from the first crease, and the third from the second crease.

Auto 50 problem solving:
1. ‘Knife error’ or ‘stop’ showing on screen.
1.1. Machine jamming with card
1.2. Knife out of position.

Try a different matrix tool

1.3. Knife pulley loose on motor shaft
2. Knife does not always cycle or behaves erratically:
2.1. Ensure knife flag is aligned with and passes through the slotted photocell.
2.2. With age and use the knife may over run at the end of cycle. Ensure that at the
end of cycle the flag is still obscuring the slotted photocell.
2.3. Check output from photocell. Place positive probe (red) of meter (set to 24v DC
range) on orange at local terminal strip and place other probe (black) on pin 29 (white/red wire) of the green IDC connector. When the photocell beam is broken (knife flag) the meter should read 5volts, other wise 0volts should be shown.
2.4. Check and change as necessary R4, the knife motor run relay.
2.5. Knife pulley loose on motor shaft
3. Paper feeds through machine without being creased:
3.1. Ensure a crease position is set.
3.2. Check output from photocell. Place positive probe (red) of meter (set to 24v DC
range) on orange at local terminal strip and place other probe (black) on pin 31 (white/blue wire) of the green IDC connector. When the photocell beam is broken (paper present) the meter should read 5volts, other wise 0volts should be shown.
4. Feed motor does not run:
4.1. Ensure cover is closed (white/brown wire).
4.2. Ensure catch tray is properly attached.
4.3. Ensure main (large 11 pin relay) is actuated. Contacts are in up position.
4.4. Ensure motor inverter shows green LED (enabled). If LED is red, motor is not
enabled.

5. Paper does not feed:
5.1. Ensure compressor is on.
5.2. Ensure side lay are not too tight
5.3. Ensure paper stack is “floating”.
5.4. Check gate position.
5.5. Check throttle position.
5.6. Ensure suction relay (leftmost small relay) has actuated. Relay with grey wire to
right of 11 pin. Contacts are up.
5.7. Ensure suction valve has operated. I.e. solenoid has “pulled in”
5.8. Check setting of solenoid for suction valve. Release valve body cap (two 5mm
set screws) to allow a 1mm gap between the cap and the body. Loosen the the hex bolts holding the solenoid block to the cover plate. Pull the solenoid block away from the valve until there is no slack in the system. Tighten hex bolts. Now tighten set screws in cap. This last action will force the solenoid bolt out of the solenoid.

6. Crease position is not accurate. Set a new job with 1 crease. Turn the air off. Remove stack from feeder. Feed a single sheet several times through the Creaser. Does the crease line move? If yes: Side lays set too loose, feed restricted.
6.1.1. Side lays set too tight, page twisting.
Set a new job with 4 creases set at 50, 100, 150 and 200mm. Run 8 pages. Line up the leading edges together. Are the first creases in line? No: Feed Gate set too wide, over feeding. Ensure the job is feeding consistently and not overfeeding.
Line up the first creases together. Are the second, third and forth creases in line? Check entry roll pressure. Release screws in roll bearings. Ensure roll is free to lift. Feed two 1” strips of 80gsm (20 lb) paper at extreme ends of roll. Tighten locking screws. Check tension of 180xl belt on rollers and tighten as necessary.
