Abstract
Weft gripper drive for looms of the type consisting of a flexible perforated tape at one end of which a gripper is fixed and of an oscillating gear-wheel that enmeshes with the tape along part of its circumference, whereby guiding devices are provided where the tape leaves the wheel, characterized thereby that the tooth height of the wheel is smaller than the thickness of the tape and that the form and dimensions of the teeth and of the perforations barely allow a mutual enmeshment, whereby the side of the tape directed towards the wheel, in the enmeshment zone, is tangent to the root circle of the gearing of the wheel.
