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 a dobby loom having a plurality of heddle frames, in particular having a changeover device for weft threads, according to the invention the heddle frames (4, 6, 8, 10) are each connected to a linear motor, such that by means of controlling the linear motor the heddle frame (4, 6, 8, 10) can be moved from an upper maximum position to a lower maximum position and vice versa. In one embodiment, the dobby loom has a plurality of warp thread presentation means, for example color control needles (18, 20), for the selective introduction of different weft threads (40, 42) into the warp shed and for changing the weft threads (40, 42). The loom comprises a control unit for controlling the linear motors, which control unit is designed to enable the control of a specified position of the heddle frame (4, 6, 8, 10) between the upper maximum position and the lower maximum position at a predetermined point in time. Said control unit has a sensor unit by means of which the position of each of the heddle 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...
