Embodiment Construction

[0021] exist figure 1 A particularly advantageous embodiment of the invention is shown in . here figure 1 Shows the main elements of a rapier loom with a weft insertion device, wherein the respective color control means, in the embodiment shown, a weft selection device 18 for a first color and a weft selection device for a second color The device 20 is assigned correspondingly to the heald frames 4 and 6, the movement of which can control the selective introduction of the respective weft threads. The further heald frames 8 and 10 here conventionally correspond to the structure of the shed. The other elements of the rapier loom, namely the reed 28 and the stopped fabric 26 as well as the warp threads in the upper shed 22 and the warp threads in the lower shed 24 represent here other conventional elements of known rapier looms . This application is only possible if the loom has a control device for controlling the linear motor of the rapier, which is constructed so that at a...

Abstract

In order to improve rapier looms with multiple heald frames, especially alternating devices for weft yarns, it is proposed that the heald frames (4, 6, 8, 10) are respectively connected to linear motors, through whose control the heald frames (4 , 6, 8, 10) Movement from the maximum position above to the maximum position below and reverse. In one embodiment, the rapier loom has a plurality of weft selection devices, such as color control needles (18, 20), for selectively introducing different weft yarns (40, 42) into the warp shed and alternating weft yarns (40 , 42). The weaving machine includes a control device for controlling the linear motor, which control device is configured to control the heald frame (4, 6, 8, 10) at a predetermined time between an upper maximum position and a lower maximum position. the predetermined position. The control device here has a sensor device by means of which the position of the individual heald frames (4, 6, 8, 10) can be detected continuously.

Description

technical field [0001] The invention relates to a rapier loom, especially a belt loom, with a shed forming device, the shed forming device has a rapier device and a heald frame, wherein the heald frames are respectively connected with linear motors, through which the heald frames can be controlled, Movement of the heald frame from an upper maximum position to a lower maximum position and vice versa is performed, and the loom has a weft insertion device for introducing one or optionally a plurality of weft threads into the warp shed. Furthermore, the invention also relates to a corresponding weaving method. technical background [0002] Shedding devices for weaving machines with rapier devices and heald frames are known from a large number of documents. A weaving machine is known from WO-A-98 / 24955, in which a pick-up element of the weaving machine for picking up warp threads, for example a heald frame, is clamped between two springs. Here, the picker is swiveled and the fa...
