摘要： In a sewing machine with a device for setting the feed movement of a cloth feed by a revolving stitch regulator adjustable relative to the main shaft and comprising an eccentric which is connected to the cloth feed via a transmission and whose setting element is, after locking engagement with the housing of the sewing machine by a fixing element adjustable in stepwise setting amounts by rotation of the main shaft, and which is equipped with a display device for indicating the adjustment amount of the setting element, a pulse generator is coupled with the main shaft of the sewing machine for the visible display of the feed amount during operation of the machine. The pulse generator cooperates with markings which deliver pulses corresponding to the stepwise amounts and can be switched on via a switch actuable upon locking engagement of the setting element. The pulse generator is connected to a display unit via a pulse evaluating device.
