AI Technical Summary

Problems solved by technology

A certain degree of delay is therefore introduced, which can sometimes adversely affect the resulting band segments
Since the entraining discs, usually knurled discs, grip directly on the belt material, compression deformations of the material can also occur, which can likewise have a detrimental effect on said material

Embodiment Construction

[0031] figure 1 A slitting machine 1 according to the invention is shown with a machine frame 2 , at least one cutting unit 3 and a supply device 4 . The cord strips to be cut are supplied via a supply device 4 . The supply device has a series of individual support rollers or guide rollers 5 for this purpose (see also for this Figure 7 ), the cord belt travels on the idler roller or guide roller. The rollers 5 are part of a control frame 6 which is arranged rotatably about a vertical axis 7 on the machine frame 2 .

[0032] The cord tape is fed through an entry guide 8 comprising a plurality of protruding guide fingers (alternatively guide plates can also be provided) and runs on a control frame 6 or on rollers 5 . Servomotor 9 is used to adjust the oscillation about vertical axis 7 . By controlling the corresponding oscillation of the frame 6, the relative position of the cord band with respect to the cutting unit 3 is defined.

[0033] Behind the supply device 4 is con...

Abstract

The present invention relates to a slitter for cutting a cord band, which comprises a frame structure, at least one cutting section and conveying section, wherein a cord band to be conveyed to the cutting section is guided by the conveying section, the cutting section comprises a first cutter shaft and a second cutter shaft, the first cutter shaft is driven by a driving means and the first and second cutter shafts are arranged in parallel with each other and are operated together to carry out cutting, and the cord band to be cut is passed between the first and second cutter shafts. In the slitter, a conversion roller (10) is disposed above the first cutter shaft (16), and the cord band (34) introduced from the conveying section (4) is wound around the conversion roller partially and is changed in direction toward the first cutter shaft (16) by the conversion roller so that the cord band (34) may be wound around the cutter shaft (16) partially before cutting.

Description

technical field [0001] The invention relates to a slitting machine for cutting cord strips, having a machine frame, at least one cutting unit and a feed / feed device, by means of which the cords to be fed / feed to the cutting unit are guided Belt, wherein the cutting unit includes a first knife shaft and a second knife shaft driven by a driving device, the first knife shaft and the second knife shaft are arranged parallel to each other and work together for cutting, the cord to be cut A belt passes between the first arbor and the second arbor. Background technique [0002] Such a slitting machine is known, for example, from DE 20 2013 104 653 U1 for cutting rubber-coated cord material used in the web processing industry. A slitting machine is a longitudinal dividing device with which the cord web is divided into at least two material strips as required during the production process. This is used to increase the output of processing equipment. The cord tape material is suppl...
