Abstract

PURPOSE: To facilitate the changeover of gather sewing and normal sewing and the change of the size of a gather amount and to improve work efficiency by making one of the feed amounts of a vertical feed means changeable during sewing by the switch operation of an operator. CONSTITUTION: When power is supplied, the previous set values of setting switches 1a-1c are stored in a storage circuit 2 and the corresponding set values of the setting switches 1a-1c, for instance, feed ratios 1:1, 2:1 and 4:1, by the set state of selection switches 3a-3c are read and outputted. At the time of assuming that sewing is advanced from a point g1 and the selection switch 3a is selected, the feed ratio 1:1 is read from the storage circuit 2, a pulse motor 7 is controlled, a lever is moved to a prescribed position, a sewing machine is activated by a pedal operation or the like and sewing is started. Then, when stitch reaches a point g2 , when the operator operates the selection switch 3c for gather sewing, the feed ratio 4:1 is read, the lever is moved to a prescribed position by the pulse motor 7, an upper feed amount is increased and the gather sewing of a part Ab is started.
