The invention relates to one for aligning weft threads in a moving web of fabric serving device that includes a sheet aligner, a diagonal aligner and an electronic Scanning and control device is provided for the alignment units.

In the case of the known devices of the above type which are generally customary in the processing industry a major disadvantage in that due to the different distances from the electronic scanning and control means arranged sheet aligner and diagonal aligner by the aforementioned Control impulses given to the device do not always have an effect at the most favorable moment can and therefore do not fully meet their intended purpose.

The purpose of the invention is to eliminate this disadvantage by means of an improved construction. Is to According to the invention, the sheet aligner between two diagonal aligners mounted in a common frame arranged, in a manner known per se (see. The USA. Patent 7 742 685) by a their longitudinal axis can be pivoted in the middle of the axis crossing vertically.

An embodiment of the device according to the invention is shown in the drawing. In it shows

F i g. 1 shows a diagram showing the path of the cloth web through the new device and

F i g. 2 shows a schematic and diagrammatic representation the device.

As shown in FIG. 1 of the drawing can be seen the various organs of the new device are arranged in a frame 10 shown schematically. The device is equipped with a feed roller 1, a discharge roller 7, two smooth rollers 2, 6 for Align the diagonal skew of the weft threads in the running cloth web, which together form the diagonal aligner form, two smooth curved rollers 3, 4 for aligning lying in the running cloth web, curved weft threads, which together form the sheet aligner, as well as with one with the curved Rolls 3.4 cooperating guide roller 5 is provided. In the FIG. 1 and 2 specified In this way, a web of cloth 12 is guided around rollers 1 to 7 inclusive. After going through of the aligner complex, the cloth web 12 passes an electronic scanning and not shown Regulatory device whose drives control the alignment complex. The electronic scanning and regulating device is of known design, so it will not be further discussed needs to be.

The straight rollers 2, 6 of the diagonal aligner (diagonal rollers) can be rotated freely around the axis, which are mounted in a right-angled frame 8. The right-angled frame 8 with the rollers 2, 6 is mounted pivotably in the frame 10 with axle journals 9.

When the frame 8 is pivoted by means (shown schematically in FIG. 2), the Diagonal rollers 2, 6 assume an inclined position with respect to the surface of the cloth web 12. Will the Diagonal rollers 2.6 z. B. erected obliquely to the right with respect to the direction of displacement of the cloth web 12, so the distance which the cloth web 12 has to cover on the right side will be shorter than the one on the left. Are the diagonal rollers 2, 6 obliquely to the left with respect to the direction of displacement of the cloth web 12 erected, the distance of the cloth web is shortened on the left side and extended on the right. That side of the running cloth web that is going through the device has to travel a longer distance, so it is behind the side that has a shorter one Must cover distance, lag behind, whereby the diagonal skewness of the weft threads is canceled.

The rollers 3, 4 of the sheet aligner (sheet roller

zen) are freely rotatable about axes 11 '. As shown in FIG. 1 and 2 can be seen, the bow rollers 3, 4 are bent in the same direction, which is illustrated by the arrows shown.

Claims (1)

When the bow rollers 3, 4 the in F i g. 1 and 2, they are in the Neutral or zero position. When the bow roller 3 is at an angle clockwise and the bow roller 4 is rotated through an equally large but oppositely directed angle, so will the bow rollers 3, 4 pressed into the running cloth web 12. This will make the middle part of the cloth web 12 forced to cover a greater distance than the more laterally lying parts. The middle one Part of the cloth web 12 will therefore remain behind the side parts, causing a movement in the direction of movement the leading sheet of the weft threads is pressed out of the web. If a relative to the direction of movement of the moving cloth web 12 lagging sheet of the Weft threads are to be canceled, the bow roller 3 is counterclockwise and the bow roller 4 at the same angle but adjusted clockwise. Characterized in that, according to the invention, the diagonal roller 2 in the feed direction of the current to be treated fenden cloth web viewed, in front of and the diagonal roller 6 is arranged behind the bow rollers 3, 4, the diagonal aligner and the arch aligner of the aligner complex are at the same distance from the electronic scanning and regulating device. Claim: Device for aligning weft threads of a running fabric web with a sheet aligner, Diagonal aligner and electronic scanning and control device for the alignment units, characterized in that the sheet aligner (3, 4) between two in a common Frame mounted diagonal aligners (2, 6) is arranged in a known per se Way about an axis (9) perpendicularly crossing its longitudinal axis in the middle.
