The giver is used with a gripper loom having a stationary weft supply and includes a tongue in the gripper casing and a clamping element on a wide side of tongue so devised that clamping element bears to some extent on the underside of the gripper casing. At the entry and clamping zone of the yarn, the clamping element takes the form of a thin flat spring strip which follows the curvature of the tongue and which is secured thereto at one end while at a central region the clamping element presses a clamping surface of the gripper casing. When a member moves the tongue away from the gripper casing, the clamping element also disengages from the clamping surface, so that dirt between the clamping surfaces of the tongue element and casing can drop away or be extracted.

Giver for a gripper loom

In the filling-thread insertion element or delivery gripper, a transport clamping tongue supports an upper supplementary clamping tongue which is provided with a slot. The upper supplementary clamping tongue is appreciably thinner than the transport clamping tongue. The upper supplementary clamping tongue can therefore lie elastically against a clamping location between the transport clamping and upper supplementary clamping tongues on the one hand and a clamping jaw on the other hand. Furthermore, the upper supplementary clamping tongue is adjustable by means of a screw, which enables its clamping force to be adapted to the filling or weft thread currently employed, respectively to its thickness. It is in this manner possible to perform double-pick or weft insertion with secure clamping of two filling or weft threads in a weft thread entry slot.
