1. Product specifications

1.1 Short description and use for the intended purpose

The 171 and 173 are double chainstitch (stitch type 401) sewing machines in single or twin needle version. The loopers are across the line of sewing (Crossline). Class 171 with drop oscillation feed. Class 173 with drop oscillation feed and intermittent top puller feed. The feeding lengths of feed dog and puller are independently a dj ustable at separate dials. When changing over to stitch condensing, the feeding length of the puller is automatically reduced accordingly. In accordance with the intended purpose, the machines must only be used for sewing materials made of textile f ibres and leath er.

1.2 T echnical data
