A draw-through gripper for the gripping and insertion of an auxiliary weft thread into a seam-weaving shed in a seam-weaving machine includes a movable gripper arm with a gripping collet for grasping the auxiliary weft thread. An apparatus for measuring the mechanical stress occurring inside the gripper arm is mounted on the gripper arm. The apparatus for measuring the mechanical stress occurring within the gripper arm can be a strain gauge.

A separator for successively seizing threads (14) held in an array (28) includes a frame (10) having a front face or recess gap (12) and in which two or more strap or bar needles (15, 16, 18) are slidably disposed side by side. Each needle is provided with a pair of facing hooks (20, 22; 24, 26) at opposite sides of a cutout in its forward edge for cooperatively seizing a single thread for separation when the needles are driven in opposite directions.

Mechanism for separating threads held in an array

An apparatus for inserting weft wires in flat weaving power looms wherein a shuttle is moved by carriages which are disposed above and below the shed defined by the warp wires and which are guided by magnetic means and wherein the shuttle is a gripper shuttle, the shuttle and the carriages include permanent magnets, and the drive means for the carriages is one of a stepping motor, a speed-controlled three-phase current motor and a disk rotor motor which effects positioning of the carriages and thus of the gripper shuttle at the weft transfer points by a holding force.
