ABSTRACT:
An automatic sewing apparatus for hemming and closing a sleeve is used for hemming a sleeve blank and sewing it into tubular form for making, for example, a short-sleeved T-shirt. The steps subsequent to putting the sleeve blank on a conveyor are done fully automatically and continuously to make the tubular sleeve. The apparatus according to one embodiment of the invention comprises first and second sewing machines disposed at inner corner sides of an L-shaped sewing table, a feed device having a conveying surface disposed on a table part of the first sewing machine side of the sewing table, a folding member for folding the blank edge along the feed direction, a deflecting device having a member for stopping the running of the front end of the hemmed piece above the conveying surface, and a transfer device for feeding the deflected piece of a hemmed sleeve blank to the second sewing machine.
