Problems solved by technology

[0013] However, the device described in BE 1000995 does not provide a simple and quick solution for releasing the bridges before they are positioned and for re-fixing them once the desired position has been reached
Releasing and securing the bridge is a time consuming process and also ergonomically onerous

Embodiment Construction

[0110] An embodiment of the invention is Figure 1 to Figure 3 Shown is a fabric guiding device (1) for a face-to-face loom. It comprises a cutting tool (8) and an upper bridge (2) and a lower bridge (3) positionable at an adjustable distance from each other and from the cutting tool by means of drive means (4a; 4b). The cutting knives are movable on rails firmly attached to the machine frame.

[0111] The driving means (4a; 4b) comprise first (4a) and second (4b) driving means. The drive can be realized manually (adjustable screw shaft), electrically (screw shaft + servo motor + gear unit) or hydraulically (hydraulic servo cylinder). In the device (1) shown, the drive means (4a; 4b) are mechanically connected to the end of the lower bridge (3). The system ensuring the vertical movement of the lower axle mainly consists of a mounted screw shaft and a servo motor with a gear unit. The upper bridge (2) does not have its own drive for its positioning. In order to move (posit...

Description

technical field [0001] In one aspect, the invention relates to a fabric guiding device for a face-to-face loom, comprising automatic clamping means for releasing or securing bridges, such as upper and / or lower bridges. In another aspect, the invention relates to a method for releasing and re-clamping a bridge of a fabric guiding device of a weaving machine. The invention is preferably suitable for use in looms. More specifically, the invention is suitable for use in face-to-face looms. [0002] The invention also relates to a weaving machine provided with a fabric guiding device according to the invention. Background technique [0003] In this patent application, the terms upper and lower bridges are used to refer to bridges fixed above and below the fabric across the textile width of the machine and intended to be used when the fabric is rolled up on a roll or folded in a cart. Position the crossbeams that guide the fabric in a direction away from the textile reed. [0...
