Differential feed sewing machine, with control of sewn product thickness using memory-stored adjustment parameters for different sections to adjust sewing process via control object, e.g. feed device

摘要

In a differential feed sewing machine, the sewn product thickness on a stitching plate is determined; a memory stores a set of adjustment parameters for each of a number of sewing sections in a predetermined series, with the thickness included for each section; and the operation of a control object is controlled based on the parameters in each section to adjust the sewing process and fix the sewn product thickness.
