·         Automatic functions like thread trimmer, foot lifting and stitch condensing (depending on the subclass)

·         Quick and easy conversion to a twin needle machine, needle distance of max. 15 mm possible With the conversion set 175-590074, a simple conversion from single-needle to two-needle is possible. Needle distances up to 15mm can be converted.

·         Possible applications for this: 171-131610 E208/0,4: Closing seat or side seams on classic pants. The needle distance is 0.4 mm. Parts set 550-2-2 (0550 590344): The designed workstation sews continuous zippers onto fly pieces. The sewing head, which has been converted into a two-needle machine, is equipped with a needle distance of 5 mm. And many more…

·         High sewing speed up to 6,600 stitches/min. 171: The bottom feed machines have a max. sewing speed of 6,600 stitches/min. 173: The speed-stable top puller feed operates at up to 6,000 stitches/min.

·         Optimum stitch formation due to automatic adaption of the looper thread quantity – tight but elastic seams

 

Examples of use

·         General operations garment industry. General operations – in particular long, smooth and also elastic seams. Operations in jacket and blazer manufacturing – closing seams in lining and upper fabric.

·         Jacket and blazer manufacturing. Operations in jacket and blazer manufacturing – closing seams in lining and upper fabric.

·         Classic trousers. 171-131610 E208/0,4 Close seat seams in trousers with tandem sewing equipment – the tandem foot compensates the different fabric heights during the sewing process. The needle distance is 0.4 mm. Due to the two-needle closing seam, an extremely strong and yet smooth seam is created.

·         Topstitching of trousers side seams with special edge guide from the bottom (N900 002631), swivable from right to left; for guiding the seam edge (in conjunction with sewing equipment 173 E8).

·         Sew endless zippers on flies. Set of parts 550-2-2 (0550 590344) The optimized workstation sews endless zippers on the flies perfectly. The zipper pull-off device ensures the tension-free attaching of the zipper. Depending on the processing method, a non-woven tape can be additionally carried along from below. The sewing head is converted into a double needle machine and is equipped with a needle distance of 5 mm.

·         Sew shirt back yokes. Set of parts 550-15-15 (0550 590334 + 0550 400224) Optimized workstation for sewing and top stitching of shirt back yokes: In one operation, the outer back yoke is inserted by a special attachment and topstitched together with the inner yoke and the back part. The left-hand arranged bundle clamp with rack table allows the operation flow in the waterfall principle.

·         Pinking the crotch piece of trousers. 171-131610 – Attaching and simultaneous pinking of the pants crotch piece. A grown on trousers crotch piece consumes a lot of space in the cutting pattern. Space-saving nesting of the parts is barely possible. It comes to an increased material consumption.
In order to save material and to optimize the cutting pattern, it is recommended to change the back trousers pattern and separate the crotch piece. Thus, the cutting pattern can be planned efficiently. In the workshop, the crotch piece can be sewn and pinked with the part set 550-121 in a high quality.

Output: 2,000 trouser crotch wedges / 480′ max. Example of a lower material utilization in a single size cutting pattern due to the grown on crotch piece (1.77 m material consumption each pair of trousers and size). Example of an optimum material utilization through separated crotch piece (1.63 m material consumption each pair of trousers and size = 8% material saving).

 

·         Binding mattress protector – 173 klass. Another interesting process on the 173 is the binding of mattress protectors, sunshades or household articles. A special version of the machine is equipped with a binder, automatic tape feeding and automatic tape cutting. A light barrier detects the end of the seam and the machine stops automatically to turn the sewing piece manually. If the thread cutter of the machine is actuated, the tape is automatically cut and sewn.
