1.3 Subclasses

589-212000 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. Flexible cutting (two lengths preset,

with/without eye). 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.

589-221000 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, not cutting,

flexible cutting (two lengths preset, with/without eye),

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.
