Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a guide cola for woven or biased elongated fabrics, for removing wrinkles from the elongated fabric in its width direction. It relates to something that has. This device is
It consists of a ridge projecting radially from the circumferential wall of the guide roller, which ridge extends in the running direction of the web from the center of the guide roller toward both ends. The length of fabric is guided along the outer surface of this raised portion at a predetermined wrapping angle.

2. Description of the Prior Art In known guide rollers of this type, a helical bulge extending from the center of the guide roller towards the ends of the guide roller is fitted, for example by welding, into a long length. According to the wrapping of the cloth, a good wrinkle smoothing effect can be obtained in the width direction of the long cloth.

Problems to be Solved by the Invention However, such a good wrinkle removal effect is strongly needed in certain fabrics, e.g. in particular knitted fabrics, whereas in contrast, e.g. If only a slight wrinkle smoothing function is required, or if the long fabric does not tend to shrink or contract in the width direction, such a wrinkle smoothing device is omitted. Depending on the above-mentioned treatment of the long fabric, for example when finishing the long fabric, the unnecessary wiping action is combined with the unnecessary wiping action, and this wiping action causes the long fabric to be Some of the finishing material applied to the wrinkle-smoothing device ends up adhering to a portion of the wrinkle smoothing device.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to improve a guide collar of the type mentioned at the outset so that it can provide the necessary wrinkle smoothing effect for various types of long fabrics.

According to the invention, a raised part is provided on the convex outer side of at least one cylinder segment assigned to the guide roller, such that the cylinder segment is free. The guide roller is arranged at a distance parallel to the roller peripheral wall of the guide roller that rotates.

Effects and Effects According to the invention, a length of fabric can be guided in rotation by providing cylinder segments which are arranged in a stationary manner parallel to and spaced from the circumferential wall of the freely rotatable guide roller. Alternatively, the long fabric can be guided directly on the peripheral wall of the roller, omitting the wrinkle smoothing action, or alternatively, the long fabric can be guided along the convex side surfaces of cylinder segments arranged in stationary position. Sometimes, a ridge provided on the convex side of the cylinder segment, that is, a ridge that extends in the feeding direction of the long fabric toward both ends of the cylinder segment be able to.

In order to be able to selectively obtain quantitatively different wrinkle smoothing effects, according to an embodiment of the invention, one cylinder segment is arranged in each case on the mutually opposite sides of the guide roller, and these two cylinder segments are arranged on opposite sides of the guide roller. The two cylinder segments have different radii of curvature and are accordingly arranged at different parallel distances from the collage circumferential wall of the guide roller. Such an arrangement provides six possibilities for guiding the length of fabric. First of all, the long fabric is guided directly through the guide rollers without being exposed to the crease-removal action. It is guided through the other cylinder segment, and these cylinder segments then provide a different wrinkle smoothing effect to each other.

According to another embodiment of the invention, each cylinder segment is held via two support arms, which can be clamped onto an axle on which the guide rollers are rotatably journaled. It is.

With such an arrangement, the cylinder segment is arranged in a stationary manner relative to the guide roller, which is nevertheless advantageous, especially when the length of fabric is guided around the cylinder segment directly via the guide roller. , the cylinder segments can be moved into their respective positions, and the means necessary for this do not interfere with the guidance of the length of fabric.

Embodiment Next, the structure of the present invention will be specifically explained with reference to the embodiment shown in the drawings.

A guide roller 1 consisting of one roller peripheral wall 2 and two end disks is rotatably supported on a shaft 4 via a ball bearing 3.

A cylinder segment 8 or 9 in each case is secured at a radial distance from the roller jacket 2 by a pair of supporting arms 6.7, which are each clamped to the shaft 4 by screws 5.
are held, and these cylinder segments 8, 9
are arranged diametrically opposite each other.

The length of fabric 10, indicated in FIG. You will be guided by In order to smooth out the wrinkles in the long fabric 10, the respective convex outer surfaces of the cylinder segments 8, 9 are provided with spiral ridges 11 and 12 which project radially outward. These spiral protrusions 11 or 12 extend from the center of the cylinder segments 8, 9 toward both ends in a direction in which the elongated fabric 100 is guided.
