Abstract
A carriage is moved on an ell shaped frame by a pneumatic actuator and a curved gripping device at the end of an ell shaped extension mounted on the carriage is operated by a second pneumatic actuator to pick up pieces of web material. The pneumatic actuator for the carriage is controlled by a sequence valve so as to not be movable until the gripper has gripped the web of material. A third pneumatic actuator thereafter moves the carriage at a relatively fast initial movement until the web of material has cleared the sewing machine. The carriage movement is slowed and this carriage moves the web of material to a predetermined location where it is released by the gripper to fall in a stack.
