1. Product description

1.1 Designated use

Die DÜRKOPP ADLER 579 is an automatic sewing machine designed for sewing buttonholes in light to medium-heavy material.

Such material, which is generally made of textile or synthetic fibres, is used in the clothing industry. This 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 would be happy to assist), since such applications are on the one hand relatively unusual and, on the other, they are 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 8mmwhen compressed by the lowered upper material clamps.

The material may not contain any hard objects. The machine may only be operated with finger and eye protection. The seam is generally produced with sewing threads of gauge up to 80/2 Nm (synthetic threads with or without cotton covering). Before using any other thread the possible dangers arising must be assessed and appropriate safety measures taken if necessary. This machine may be set up and operated only in dry, well-maintained premises. If it is used in other 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.

1.2 Brief description

Depending on the subclass, the DÜRKOPP ADLER 579 is a double-chainstitch buttonhole machine or a single-thread chainstitch eyelet machine with CNC step motor for fabric feed and rotating sewing mechanism.

As a buttonhole machine it works with two chainstitch loopers, the left one carrying the thread, sewing buttonholes with or without an eye, with taper, round or cross tacks.

As an eyelet machine it works with two chainstitch dummy loopers, sewing single-thread eyelets.

The various subclasses of the 579 are fitted with different thread-trimming systems.

Technical features

The machine is driven by a positioning drive built into the machine arm. The movements of the X, Y and Z axles are driven by a step motor.

These drives are controlled by a DAC 2 electronic controller in conjunction with various pneumatic machine functions.

The BF 2A operating panel is mounted in a visible location on the machine arm and is thus easily accessible to the operator. This drive-and-controller system has the following advantages:

–

Variable sewing speed depending on parameters such as the upper thread, bobbin thread, material, seam width) up to a maximum of 2200 stitches/min.

–

Very quiet operation because there is no mechanical connection and disconnection. Additional noise reduction from the new needle-bar and looper drive.

–

The use of step motors confers great versatility. No use of control cams.

–

One-pedal operation for the following functions:

- close/open clamps

- switching on the sewing process

- rapid halt with needle lift

–

Pneumatically-operated thread-trimming system with short drive distances for precise operation.

–

Pneumatic buttonhole slit.

–

Central oil-wick lubrication from two oil reservoirs.

–

Simple cutting-block replacement.

–

Seam-width alteration in the cross tack.

–

The special design of the machine arm permits the use of a different material holder (optional extra) enabling the material to be placed lengthwise.

–

Smooth design with casing. A gas-pressure spring helps to swing the machine up and ensures that the head does not swing down too quickly.

–

Vertically-operating cutting-block holders mean that no finishing-off work is necessary even with different cutting-block heights.

–

After the material has been released a display setting enables the cloth carrier plate to move to the starting position for the next buttonhole, which improves visibility for material positioning.

Controller

–

A counter, shown in the display, counts the number of buttonholes sewn.

–

A number of parameters can be set on the BF 2A operating panel, depending on the subclass and buttonhole shape. These include the following:

- with or without eye

- speed max. 2200 rpm

- buttonhole length, various ranges depending on the subclass

- cut before or after sewing

- no cutting

- stitch count in the eye

- stitch distance

- taper tack overlap

- taper tack length

- overlap in round tacks and eyelets

- overlap in the round tack

- number of stitches in the round tack

- stitch distance in the cross tack

1.3 Subclasses

579-112000 With short trimmer for the upper and bobbin threads. The

bobbin-thread trimmer is located in the throat plate, enabling the thread to be severed very close to the material. For taper, round and cross tacks. Can also be used for double-chainstitch eyelets in conjunction with appropriate sewing apparatus. Fitted as standard with an electropneumatic upper thread catcher. No lower gimp.

579-121000 With short trimmer for the upper thread and long trimmer (thread length ca. 30 mm) for bobbin thread and gimp. Cutting before or after sewing, with or without taper, round or cross tack. The bobbin thread and gimp can thus be either pulled tight or passed through to sew a lockstitch tack afterwards. After the cross tack has been sewn they are short-trimmed by hand. For cut lengths up to 38 mm: fitted as standard with electropneumatic thread catcher and gimp guide. This grasps the upper thread as soon as it is severed, holds it clamped and inserts it into the right side to sew the next buttonhole. This means:

- a secure seam start, even in light, loose weaves - tight starting stitches

- a clean buttonhole underside, hence no need for trimming.

579-141000

With short trimmer for the upper thread, bobbin thread and lower gimp. The material is not released by the material clamps until the thread-trimming process is complete, which means that the lower thread and lower gimp are trimmed very short . Cutting before or after sewing, with or without taper, round or cross tack. On this machine the buttonhole length, cut length and taper-tack length can be altered by fitting different clamp-plate sets. Clamp-plate sets for five groups of cut lengths exist. L1 for cut lengths of 12-16 mm in 2 mm increments L2 for cut lengths of 16-20 mm in 2 mm increments L3 for cut lengths of 20-24 mm in 2 mm increments L4 for cut lengths of 24-28 mm in 2 mm increments L5 for cut lengths of 28-32 mm in 2 mm increments. Within these cut-length groups various taper-tack lengths are possible. With thread catcher and gimp guide.

579-151000

With short trimmer for the upper thread. A universal machine for buttonholes with cut lengths of 10-50 mm in materials of various qualities and thicknesses, available with or without lower gimp depending on sewing apparatus. Can also be used for single-chainstitch eyelets in conjunction with appropriate sewing apparatus.
