Abstract: A festooning machine has at least one transport element for a forward transportation and transverse transportation of a sewing product, two vertically movable needles arranged at a distance near the transport element and parallel to a direction of the transverse movement with an adjustable distance therebetween, a needle drive for vertically moving the needles, and a independent drive unit which supports the transport element and provides movements of the transport element.

Abstract: A blind stitch sewing machine comprises in the transmission between its main drive shaft and the fabric feeder an arrangement for stitch shortening and tacking. This arrangement comprises a coupling device with two arms which are guided for movement in longitudinal direction relative to each other and coupled by a coupling spring. One of the arms, which is fixed to the fabric feeder for movement therewith is provided with a recess into which a solenoid operated bolt is engageable when the fabric feeder reaches its forward end position to thereby stop the one arm and the fabric feeder connected thereto, while the main drive shaft and the remainder of the transmission remain in operation. Thereby feed of the fabric is substantially stopped and the seam tacked. Subsequently thereto the bolt is withdrawn from the recess and the coupling spring will again couple the one arm to the drive.
