摘要

Method for transmitting thread-specific data in re-reeling operations for the manufacture of two-thread lock stitch seams which have to be documented comprising the following steps: the bobbin taking over the thread, in particular the under-thread bobbin (10) is provided with a definite bobbin identification, in a reeling station (28), in which thread material for the under-thread is reeled from a thread stock (30) onto the under-thread bobbin (10), the bobbin identification is detected and is stored in a data storage medium (24) together with a first data record characterizing the thread material and the reeling operation, after inserting the under-thread bobbin (10) into a sewing machine (18) the bobbin identification is detected, from the bobbin identification the first data record stored therewith is determined and is assigned to a second data record concerning the sewing operation and/or the sewn product, whereupon the data set so formed is stored.
