1 Product description

The DÜRKOPP ADLER 867 is a special sewing machine for universal use.

It is a flatbed double-lockstitch machine with bottom feed, needle feed and alternating upper foot feed.

Depending on the subclass it comes as single or double needle machine, with or without electromagnetic thread cutter, with or without edge trimmer.

Equipped with a large or oversized two-piece vertical hook.

With a maximum of 20 mm fabric clearance when sewing feet are lifted.

The residual thread length after thread trimming is about 15 mm without short thread trimming device and about 7 mm with short thread trimming device.

A safety clutch prevents a changing of the hook setting or a hook damage in the case of a thread deflection into the shuttle track.

Automatic wick lubricating with an inspection glass on the arm for machine and hook lubrication.

Integrated winder.

2 Designated use

The 867 is a sewing machine designed for sewing light to medium-heavy material. Such material is generally made of textile fibers, but it may also be leather. It is used in the clothing industry and for domestic and motor-vehicle upholstery.

This special sewing machine can also be used to produce so-called technical seams. In this case, however, the operator must assess the possible dangers which may arise (with which DÜRKOPP ADLER AG would be happy to assist), since such applications are on the one hand relatively unusual and, on the other, so varied that no single set of criteria can cover them all. The outcome of this assessment may require appropriate safety measures to be taken.

Generally only dry material may be sewn with this machine. The material may be no thicker than 10 mm when compressed by the lowered sewing feet. The material may not contain any hard objects, since if it does the machine may not be operated without an eye-protection device. No such device is currently available.

The seam is generally produced with textile-fibre sewing thread of gauge up to 11/3 NeB (cotton), 11/3 Nm (synthetic) or 11/4 Nm (covering yarn). Before using any other thread the possible dangers arising must be assessed and appropriate safety measures taken if necessary.

Keystone Sewing Machine Company, Inc.

This special sewing machine may be set up and operated only in dry, well-maintained premises. If the sewing machine is used in premises which are not dry and well-maintained it may be necessary to take further precautions (which should be agreed in advance - see EN 60204-31:1999).

As manufacturers of industrial sewing machines we proceed on the assumption that personnel who work on our products will have received training at least sufficient to acquaint them with all normal operations and with any hazards which these may involve.

6.2 Adjusting the needle-thread tension

Pre-tensioner

When the main tensioner 2 and supplementary tensioner 3 are open (e.g. when the sewing feet are raised) the needle thread must be under slight residual tension. This residual tension is produced by the pre-tensioner 1.

The pre-tensioner 1 simultaneously affects the length of the end of the severed needle thread (the starting thread for the next seam).

–

Basic setting: Turn knurled nut 4 until its front is flush with the bolt 5.

–

To shorten the starting thread: Turn knurled nut 4 clockwise.

–

To lengthen the starting thread: Turn knurled nut 4 anticlockwise.

Main tensioner

The main tensioner 2 should be set to the minimum possible tension. The looping of the threads must be in the center of the material.

With thin material excessive thread tension can cause unwanted gathering and thread breakage.

–

Adjust the main tensioner 2 so that the stitches are uniform. To increase tension - turn the knurled nut clockwise To decrease tension - turn the knurled nut anti-clockwise

Supplementary tensioner

The supplementary tensioner 3 can be switched in to effect a rapid change in needle-thread tension during operation (e.g. with thickened seams).

–

Set the supplementary tensioner 3 lower than the main tensioner 2.

6.2.1 Adjusting the needle-thread tension on automotive machines

On automotive machines, it is possible to secure the main tensioner 2 and the supplementary tensioner 3 against altering through the user.

Adjusting the thread tension

–

Loosen the screw 6 and remove the interlock mechanism 7.

–

Adjust the needle-thread tension according to the description given under chapter 6.2.

–

Put on the interlock mechanism 7 again and secure it by fastening the screw 6.

6.5 Adjusting the thread regulator

Caution: danger of injury !

Turn off the main switch. The thread regulator may only be adjusted with the sewing machine

switched off.

The thread regulator 1 controls the quantity of needle thread required for stitch formation. The thread regulator must be precisely adjusted for an optimum result.

At the correct setting the needle-thread loop must slide at low tension over the thickest point of the hook.

–

Undo screw 2.

–

Adjust the thread regulator 1. Thread regulator to the left = more thread Thread regulator to the right = less thread

–

Tighten screw 2.

Adjustment information:

If the maximum quantity of thread is required the thread-tensioning spring 3 must be pulled upwards about 0.5 mm from its lower limit position. This is the case when the needle-thread loop passes the maximum hook diameter.

6.15 Sewing-foot stroke

The special sewing machine 867 has, depending on the subclass, as standard equipment two setting wheels for the sewing foot stroke.

With the left setting wheel 2 the standard sewing foot stroke from 1 to 9 mm is selected.

With the right setting wheel 1 an increased sewing foot stroke from 1 to 9 mm is selected.

–

Turning the setting wheel 1 and 2 (1 to 9) 1 = minimal sewing foot stroke 9 = maximal s ewing foot stroke

Automatic limiting of the number of stitches Machines without thread trimmer

With these machines the speed is not controlled Please take into consideration the hint and the chart on the next side.

Machines with thread trimmer

The sewing-foot stroke and stitch rate are interdependent. A potentiometer is linked mechanically with the adjusting wheel. By means of this potentiometer the control unit detects what foot-stroke has been set and restricts the speed of rotation accordingly.

Machines with electro-pneumatic rapid stroke adjustment

With fabric parts that are thicker or in order to sew over cross seams, the increased sewing foot stroke (setting wheel 1) can be switched on during the sewing process by actuating the knee switch 3 beneath the table top. . As with the machines that are equipped with a thread trimmer, the potentiometer is also available.

CAUTION Danger of breakage!

The standard sewing foot stroke that is set with the setting wheel 2 may never exceed the stroke set with the setting wheel 1.

Keystone Sewing Machine Company, Inc.

6.15.1 Adjusting the sewing foot stroke on automotive machines

6.16 Setting the stitch length

The special sewing machines 867 are, depending on the subclass, equipped with two setting wheels. Thus, two different stitch lengths can be sewn, that are activated by actuating a key (see chapter 6.16).

The two stitch lengths are set with the setting wheels 1 and 2 on the machine arm.

–

Set the higher stitch length with the upper setting wheel 1. Setting 1 = min. stitch length Setting 12 = max. stitch length

–

Set the smaller stitch length with the lower setting wheel 2. Setting 1 = min. stitch length Setting 12 = max. stitch length

The stitch length are the same for both, forward and backward sewing.

–

For the manual sewing of tacks, push the stitch regulator lever 3 downward. The machine sews backward stitches as long as the s titch regulator lever 3 is being pushed.

Hint

In order to facilitate the setting of stitch lengths, the stitch length that remains unchanged should be activated with key 2 (see chapter 6.16).

CAUTION Danger of breakage!

The stitch length set with the lower setting wheel 2 must not exceed the stitch length set with the upper setting wheel 1.

Keystone Sewing Machine Company, Inc.

6.15.1 Adjusting the stitch length on automotive machines
