Abstract
A feed device on a sewing machine having a feeder which is firmly connected with a horizontal shaft which is displaceably mounted in a feed rocker mounted fixed in a housing, and having a drive for the longitudinal axial movement of the shaft. For the reduction and simplification of the drive for the longitudinal movement of the shaft, this drive is arranged directly on the feed rocker. In addition, the horizontal shaft has a gear system with which a gear segment cooperates which together with its drive elements is mounted on a flange firmly connected with the feed rocker. The drive occurs via a step motor which is secured on a flange plate of the feed rocker lever.
