ABSTRACT:
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.
