ABSTRACT:
The embroidering frame of the shuttle embroidering machine comprises cloth beams drivable via drive means. The cloth beams coact in pairs to receive between each such pair a respective material web. These material webs are superimposed in the frame plane and at each material web there engages at each longitudinal edge of the web material a rod-shaped temple or spreader. The upper and lower cloth beams both for the upper and lower material webs are each in selective driving connection by a respective endless belt of the drive means with the driving shaft of an associated geared motor of the drive means and which is carried by the embroidering frame. A belt tensioning device which is reversibly switchable with the rotation direction of the associated geared motor is used. The control circuit of the geared motors contains switching means for the selective separate or synchronous operation of the two geared motors. These measures ensure a beaming or winding-on of the individual not yet embroidered material webs and a synchronous rebeaming or winding-up of the embroidered material webs in a simple and operationally reliable manner.
