The innovation relates to a straightening device for straightening unwindable endless materials such as wires, cables, pipes, ropes and profiles with several straightening rollers which are arranged in two rows offset from one another in a base body, whereby the straightening rollers of at least one row are arranged in the base body perpendicular to the running direction of the endless material so as to be adjustable towards or away from it.

With such straightening devices, it is necessary to precisely adjust the individual straightening rollers according to the straightening process and the diameter of the material to be straightened, which requires micrometer screws that enable the adjustments to be reproduced. If all of the straightening rollers have to be adjusted more or less, the entire process is extremely labor-intensive, so that in order to reduce the work, a row of straightening rollers is arranged in a fixed position so that adjustment using micrometer screws is only necessary for some of the straightening rollers.

The aim of the innovation is to improve a straightening device of the type mentioned at the beginning so that a reproducible adjustment of the movable straightening rollers is possible with little effort.

This object is achieved by a straightening apparatus having the features of claim 1.

Advantageous embodiments of the innovation can be found in the subclaims.

The invention is explained in more detail below using an embodiment example with reference to variants and with reference to drawings. It shows:

Fig. 1 is a plan view of a straightening device , Fig. 2 is a section along line H-II in Fig. 1, Fig. 3 is a partial section along line III-III in Fig.

A straightening device has a base body 3 containing two jaws 1, 2 with a lock 4 for opening and locking the jaws 1, 2 in a position adjacent to one another as shown in Fig. 1. In the exemplary embodiment, the straightening device has four straightening rollers 5 in one jaw 1 that are fixedly arranged on a line parallel to the dividing line between the jaws 1, 2. Adjustable straightening rollers are arranged on the jaw 2 in the gap between the straightening rollers 5 of the jaw 1. To ensure adjustability, parallel grooves 7 are made in the jaw 2, in each of which a sliding block S carrying an adjustable straightening roller 6 is movably arranged. The sliding block 8 is against an adjustable screw 9 that can be fixed by a lock nut 10.

supported. The position of the sliding block 8 in the groove is adjusted by screwing and unscrewing the screw 9 in its bearing. The sliding blocks 8 are designed in such a way that they are at least flush with the surface of the jaw 2 or protrude slightly beyond it (see Fig. 2). In the area of the grooves 7 for the sliding blocks 8, grooves 11 are incorporated into the surface of the jaw 2, parallel to the parting plane between the jaws 1, 2 and perpendicular to the adjustment direction of the sliding blocks 8.

As can be seen from Fig. 3, the grooves 11 can, for example, have a wedge-shaped, rectangular, rounded or undercut cross-section. Between grooves that are at the same distance from one another and have a larger cross-section, one or more intermediate grooves 12 that evenly divide the distance and are preferably smaller in cross-section can be incorporated.

In order to facilitate cleaning of the grooves 11 or intermediate grooves 12 from dirt that occurs during straightening, the grooves 11, 12 can be filled with a mass 13 in such a way that the jaw 2 has a smooth surface (see the left part in Fig. 3). The mass 13 can have the same color in each groove 11, 12 or in every second, third, etc. groove 11, 12, so that additional marking of the grooves 11 or intermediate grooves 12 is possible.

Due to the presence of the grooves 11 or the intermediate grooves 12, the position of the sliding block 8 and thus of the adjustable straightening rollers 6 can be easily and reproducibly adjusted without a micrometer screw.
