ABSTRACT:
A sewing device comprises endless conveyer belts for feeding a sewn product on a feeding surface, a feeding drive unit, a sewn product supporting member which is provided under the endless conveyer belts on the feeding side of the sewn product and a cloth end detecting means which is provided between the needle position line of a pair of sewing machines and the sewn product supporting member for detecting either of the front end portion or the rear end portion of a preceding sewn product when a given interval is formed between the preceding sewn product which has been fed by the endless conveyer belts and a following sewn product which is placed on the sewn product supporting member, wherein the feeding drive unit starts operation upon completion of lifting of the sewn product supporting member which carries the following sewn product thereon and stops operation when the cloth end detecting means detects either of the front end portion or the rear end portion of the preceding sewn product. As a result, it is possible to constantly keep a proper interval between the preceding sewn product and the following sewn product which is placed on the sewn product supporting member so as to rationalize the cut-off operation of continuously sewn products.
