Abstract
A pair of weft carrying grippers, of the type wherein the weft yarn is retained by engagement of the head of a slider moving lengthwise, with a counteracting cooperating surface of the gripper body, the slider being thrust forward by a spring and being released by pulling a flexible lamina element connected thereto. In this pair of grippers, the flexible lamina element causing the release of the slider is controlled by a rotary cam having a slightly curved contour, around which the element may wind smoothly. Moreover, the slider head is shaped like a helical wedge, adapted to mate with an equally shaped counteracting surface of the gripper body, or it may carry at least one spring lamina, adapted to engage with a substantially flat counteracting surface of the gripper body.
