Abstract
A gripper loom with at least one filling thread insertion device, including a perforated flexible insertion band, which carries a gripper head at one end and which is advanced into and again retracted from a shed by an alternatingly driven drive wheel. The drive wheel has teeth distributed across the circumference which engage into perforations of the insertion band. Furthermore, a guide member is assigned to the drive wheel near the gripper head so as to prevent the insertion band from lifting off the circumference of the drive wheel, and an end of the band facing away from the gripper head is fastened at a rotary guidance apparatus arranged with respect to the drive wheel so that the band end describes an at least approximate circular guide path during an entire reciprocating motion, the radius of the path being larger than the radius of the drive wheel.
