Stitch loosening device for perfect shoulder pads
Your benefits at a glance
Secured sewing startFor a secured sewing start, a low thread tension and stitch condensing can be switched on.
Material thickness detection
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
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.
Switchable fullness either in the upper or lower fabric layer at the touch of a button
Fullness value
Switchable fullness either in the upper or lower fabric layer at the touch of a button.
The fullness value is mechanically adjustable and – depending on the application – it can be switched on in the upper or lower fabric by push button.
Stitch loosening finger (long and short version) to adapt the thread quantity to the thickness of the shoulder padThe switchable stitch loosening device prevents squeezing when the shoulder pad is sewn through. Thus, the pad retains its volume and soft touch.
Oil- Lubrication
The central minimum oil wick lubrication is positioned with an eyeglass in the arm. Optionally it can be equipped with a warning light as an oil deficiency indicator (9850 86700)
Large three-piece vertical hook 26 mm with 60% higher bobbin thread capacity
Large three-piece vertical hook
Large, three-part vertical gripper Ø 26 mm has 60% higher bobbin capacity for reduced bobbin change. The optimized hook allows lowest thread tension.
6-function key bar with quick access and favorite key for the functions: fullness on top, fullness on bottom, 2nd foot stroke, 2nd stitch length, automatic material thickness detection, edge trimmer ON/OFF (only on 680)
Edge trimmer for perfectly trimmed excess lengths of lining and shoulder pads
Pneumatic edge trimmer
The pneumatic edge trimmer of the 680 can be easily switched on and off via a function key. Cutting widths of 6.4 mm, 8 mm and 10 mm can be realized in combination with stitch lengths of 6 or 9 mm.
Examples of use
Attach sleeve lining through the shoulder pad into the armhole
In doing so, the wearing comfort will be increased by full ness into the sleeve lining. In order to maintain the soft grip of the shoulder pad, the stitch loosening device provides for a loose stitch tension and the correct amount of thread during the stitch formation so that the shoulder pad is not compressed.
Performance examples in 480 min.:
160 – 200 Sleeve lining through the shoulder pad
Attaching sleeve heads / wadding stripes
If the sleeve head is sewn after attaching the sleeves, the practical post bed construction offers an optimal handling of the material.
Performance examples in 480 min.:
400 – 460 Pairs of sleeve heads / wadding stripes
Attach sleeve lining in the lower armhole area
In this processing the sleeve lining is sewn only in the lowerpart of the armhole. The lining is basted in the region of the sleeve head by blind stitching afterwards.
