1. GENERAL

General
General Description
The machines of the multipli 35 folder line work on the buckle fold principle. They can be used for a wide range of applications because it is possible to choose between different types of feeders or to use one or two fold units.
The most important folds are:
Single fold
Letter fold
Double parallel fold
Crossfold
Fold Principle
Accordion fold
2
The infeed rollers (1 and 2) transport the sheet to be folded into the fold plate (4). As soon as it comes up against the adjustable
1
4
3
stop, the sheet forms a buckle because the infeed rollers keep on moving. The loop gets bigger until the sheet is seized by rollers (2) and (3); this is where the actual fold occurs. The rollers draw the folded sheet from the fold plate and the infeed rollers and move it on.

3. PROPER HANDLING OF THE MACHINE

The machines of the multipli 35 folder line are built for folding paper. They may also be used for perforating, scoring, slitting, cutting and counting paper using the proper attachments. They are unsuitable for handling other materials, such as foils, plastics and textiles. The manufacturer / distributor is not responsible for damages resulting from such unsuitable applications. Responsibility lies alone with the user.
Installation of the machine, i.e. assembling as well as electrical and pneumatic work should be carried out only by skilled personnel authorized by the manufacturer or his representatives. Additional instructions are provided for this purpose.
Repairs and service should be carried out only by skilled personnel authorized by the manufacturer or his representatives. The interval between inspections including safety-related functions depends on the machine usage. For regular one-shift operation, one inspection per year is recommended.
General
The folders may be placed on already existing sturdy tables or on mobile stands available from the manufacturer. The machine weight should be considered when choosing a table for the folder. The mobile stands are equipped with casters which can be locked to guarantee the stability of the machine during operation.
The line voltage must correspond to the voltages on the serial plate.
Read the Operator's Manual before working with the machine!
We recommend to carry out all operations and settings in the sequence mentioned in this manual so that nothing is overlooked.
The terms "right" or "left" in the following text always refer to the direction of paper travel. Therefore the right side is the operator side.

9. FRICTION FEEDER F 35

Friction Feeder F35
Function
The friction feeder F35 is especially suitable for separating uncoated and recycled papers. When handling coated paper such as art- or vellum papers, markings may occur which could impair the quality.
Sheet separation is done by friction from the top of a fanned paper stack. The feeder is driven by the feed roller (2), which in turn moves the infeed roller (1). The pressure roller (3) under the feed roller is stationary.
1
2
4
3
Through the rotation of the infeed roller (1) the uppermost sheet of the fanned paper stack is transported in direction of the feed roller (2). When the sheet reaches the feed roller (2), it is gripped by the roller and the rotating movement moves the sheet on to the first pair of rollers (4) where the actual fold occurs. As soon as the trailing edge of the sheet has left the feed roller, the infeed roller grips the next sheet from the top and again transports it in direction of the feed roller.

• Loosen the knurled nut (5) at the two feed guides by turning it counter­clockwise.
• Set both feed guides roughly to the desired format.
• Manually fold a sample sheet length­wise down the middle (7).
• Place the sample sheet (7) on the feed table in such a way that the fold is located roughly near the center of the feed roller.
• Place the left feed guide (6) against the sheet, using the locating holes (8) as a guide.
• Tighten the knurled nut (5) of the left feed guide.
• Slide the right feed guide against the edge of the sheet without actually touching it, leaving a gap of approx. 0.5 mm.
• Tighten the knurled nut of the right feed guide.

SERIOUS INJURY MAY RESULT!
• Switch on the machine - knob (1) in position I.
• Move the feeder until it audibly engages in the rest position (2).
• Push open the setting disk (3) and turn it counter-clockwise by about one turn. This lowers the pressure roller. The gap between feed- and pressure roller is increased.
• Slide an unfolded sheet between feed- and pressure roller and hold it tight (4).
Hold on to the sheet to avoid that it is gripped by the feed roller and then folded.
• Keep the sample sheet in this position and use your other hand to slowly turn the setting disk (3) clockwise until you feel a slight resistance when pulling back the sheet. The gap between feed- and pressure roller is now set to the thickness of the sheets to be folded. Now remove the sample sheet.
• Switch off the machine - knob (1) in position 0.

• Place the setting disk (3) back in rest position to avoid accidental movement. Corrections can be made with the machine running.
• Loosen the knurled nut (5) at the feeder. By changing the location of the knurled nut the contact pressure at the feeder can be set to the type of paper:
Light grades of paper (below 60 GSM):
Only light pressure necessary, push in direction of the delivery section.
Medium weight papers (60 to 90 GSM):
The weight of the feeder itself is sufficient, neutral mid-position.
Heavy paper grades (more than 90 GSM):
Higher pressure needed, push in direction of feed section.

10. AIR FEEDER S 32

Air Feeder S 32
Principle of Operation
Description
The air feeder S32 is suitable for handling a wide variety of papers. It separates uncoated paper as well as coated, freshly printed or thin papers. The sheets are separated by air and vacuum. Air is supplied from the bottom of the stack both on the left and right side, separating the paper in the stack which now floats on a cushion of air. A rotating suction drum can then separate the sheets from the bottom of the paper stack. This principle has the advantage that paper can be reloaded continuously. There is no need to stop the machine.
Components and operating elements of the air feeder S 32:
1 Rear paper stop 2 Air guides left and right 3 Feed table 4 Front paper stop 5 Knurled screw for locking
the suction segment

Setting the Format
The paper should be positioned in such a way that it is fed approximately
from the center.
• Loosen the knobs (1) by turning them counter-clockwise.
• Loosen the lock levers (2) by turning them counter-clockwise. They can be moved to a con­venient position for tightening by lifting and then turning them.
• Set the left air guide to half the paper width with the help of the scale (3).
• Tighten the knob and the lock lever of the left air bracket.
• Place a paper stack of about 50 sheets on the feed table.
• Slide the right feed guide (4) against the stack.
Do not pinch the stack, leave at least 0.5 mm between paper stack and guide.
• Tighten the knob and the lock lever of the right air guide.

Air Feeder S 32
Setting Sheet Separation
Sheet separation is achieved by the combined action of the rotating suction drum, the paper stop and the air. Paper weight and type of paper have an influence on the setting.
Setting the air:
A suction drum (1) separates the sheets from the bottom of the paper stack. This is achieved by the suction segment (2) inside the suction drum. The angle of the suction segment with respect to the paper stop can be changed to suit the different types of paper.
4
2
1
Basic setting:
• By turning the handwheel, move the suction drum (3) to such a position that a row of suction holes is in the uppermost position (4) of the suction drum.
3
Proper adjustment can be checked as follows:
Place a sheet (5) against the edges of the cutout in the suction drum (6). This marks the centerline of the drum.
The sheet must cover the left half of the suction holes (7), while the right half (8) is still visible.
• Change the angle of the suction segment in such a way that the openings in the suction segment (9) line up with the next row of suction holes (10) in direction of paper travel.

Set the suction segment as follows:
• Loosen the knurled screw (1) by turning it counter-clockwise.
• Move the swivel lever (2) up or down, thus swinging the suction segment to the required position.
Heavy paper grades: move swivel lever up Light paper grades: move lever down
• Tighten the clamp lever by turning it clockwise.
Setting for light paper grades:
Light paper grades easily cling to the curve of the suction drum. Therefore, the suction segment must be tilted in direction of the paper stop.
For running light-weight paper, first try the setting as described under "Basic Setting".
The inclination of the suction segment in this direction has the effect that the paper is wrapped around the suction drum (4). The sheets are easily separated from the stack and double sheets occur very rarely.
2

Setting for heavy paper grades:
Heavier paper grades do not easily cling to the curve of the suction drum. For this reason, the suction segment must be tilted in direction of the paper stack.
The inclination of the suction segment in this direction has the effect that the paper is wrapped around the suction drum (5) very little. This is sufficient because heavier paper grades are more easily separated from the paper stack.
