Apparatuses, methods, and computer program products for quilting webs without compressing the webs. A quilting machine includes a needle bar to which needles are attached, needle thread passing through each needle, a looper shaft to which loopers are attached, a looper corresponding to each needle and from which looper thread is provided to form stitches, and a retainer bar to which spreaders are attached to facilitate stitching. A drive pulley powered by a first servo motor rotates cranks to move the needles through a cycle and rotates a belt which rotates an indexer pulley. Rotation of the indexer pulley oscillates the looper shaft and reciprocates the retainer bar. Another drive pulley powered by a second servo motor operates to move an input web through the machine between chain stitches.

A device for fastening a gripper on a gripper shaft of a textile machine, in particular a sewing machine, preferably a multi-needle sewing machine, with a support element for the gripper is described. The support element for the gripper is connected to a holder or the gripper shaft via a connecting element in such a way that the support element for the gripper is detachable from the holder or the gripper shaft. The connecting element is designed as a toggle screw or locking mechanism such that the toggle screw rotatably engages through a bore in the support element into a corresponding opening in the holder or the gripper shaft, engaging behind an abutment, or the locking mechanism is designed as a positive connection between the support element and the holder.
