Embodiment Construction

[0035] The rapier loom shown in Figure 1 comprises a weft insertion sword 1 and a weft connection sword 2, by which the yarns 3, 4, 5 can be introduced as weft yarns by the warp yarns. 6 in the shed 7 formed. The yarns 3, 4, 5 are sent to the weft insertion sword 1 through the yarn guide device 8 according to the pattern with the relevant presentation needles (presentation needles) 9, 10, 11, and then are taken up by the weft insertion sword 1 and passed through the weft cutting knife 12 cut off. The weft cutter 12 is mounted near the insertion side 13 and between the thread guide 14 and the fabric edge 15 .

[0036] Thereafter the yarns 3, 4, 5 are received from the insertion side 13 by the weft insertion sword 1 approximately in the center of the shed 7, where they are transferred to the weft insertion sword 2 and then via the weft insertion sword 2 to the opposite side of the shed 7 16 and is unclamped by latitude sword 2 there. The weft thread introduced is then beaten ...

Abstract

Method and thread brake comprising a first brake element (40), a second brake element (60) and at least one actuator (41; 84, 85), wherein the first brake element (40) is displaceable and can be forced against the second brake element (60) by the at least one actuator (41; 84, 85) in order to brake a thread (3, 4, 5), and wherein the second brake element (60) is of flexible and elongate design and is distributedly supported along its length by a spring system (61).

Description

technical field [0001] The invention relates to a yarn brake comprising a first braking element, a second braking element and at least one actuator, wherein the first braking element is displaceable and can be pressed against by the at least one actuator to the second braking element in order to brake the yarn, more specifically the weft yarn for the loom. The invention also relates to a method of using a yarn brake. Background technique [0002] BE 1010389 describes a yarn brake comprising two brake elements pressed against each other by actuators in order to brake the yarn. The yarn to be braked may include knots, yarn bumps, thick areas and other irregularities. When such irregularities or knots pass the yarn brake, force peaks will occur in the yarn. The inertia of the actuator is too high to move the actuating elements away from each other fast enough to let the knot or irregularity pass without increasing the force. To solve this problem, many small actuators with ...
