Your benefits at a glance

Secured sewing start

For a secured sewing start, a low thread tension and stitch condensing can be switched on.

Material thickness detection

Programmable, automatic material thickness detection with two values within one shoulder pad

The automatic material thickness detection scans the material thickness via a sensor and is switched on automatically. It can be programmed for symmetrical and asymmetrical shoulder pads with 2 different values within one seam. Depending on the programmed value, it automatically switches on the machine's additional functions - stitch loosening function, second stitch length, second foot stroke height and second thread tension. This guarantees a consistent volume and soft feel of the shoulder pad.

Switchable functions

Switchable 2nd thread tension, 2nd foot stroke and 2nd stitch length for the adaptation of the machine to the different material thickness

2. stroke height of the alternating foot top feed for easier sewing over the shoulder pad

2. stitch length for sewing over the shoulder pad

2. thread tension for a loose thread tension in the shoulder pad.

Fullness value
