ABSTRACT:
A method and sewing unit for folding a strip of cloth and then transporting it to a sewing machine together with a sewing material blank to which it is to be sewn. In accordance with this invention, the sewing material blank 109, which has been laid out in accordance with markings at a layout point 101 of the sewing unit, together with the strip of cloth 110, are transferred by a feed device 8 to a transfer point 106 beneath the sewing-material holder 9, which has previously been raised. A pivotable and displaceable folding-plate 94 provided on the sewing-material holder, together with a counterplate 54 of the feed device 8, carries out the folding of the strip of cloth 110. Then the folding-plate 94 is pulled forward and the counterplate 54 backward, and the feed device 8 is placed in its raised position. The sewing-material holder 9 moves the folded strip of cloth 110 and the blank 109 lying under it to the sewing point 108 at the sewing machine 3. The feed device 8 is now on its way back to its starting position in the region of the layout place 101.
