Problems solved by technology

This can result in damage to the cut piece, material breakage or cracks, which can no longer be used
Especially in the event of severe damage which cannot be removed by re-grinding, the cutting knife can no longer be used in its entirety, since the cutting element, as described, is generally non-detachably connected to the support

Embodiment Construction

[0021] figure 1 A cutting knife 1 according to the invention is shown which has a beam-shaped support 2 whose length is usually greater than 1 m, here it can be up to 6 m or longer. A plurality of individual holes 3 are distributed along its length on the support 2, such as image 3 As shown, these holes are stepped, in order to fix the cutter 1 on the corresponding section of the cutting machine, especially the steel cord belt cutting machine, the bolts are inserted into these holes, so that the bolts are supported with their bolt heads on the corresponding hole on the ladder.

[0022] In the exemplary embodiment shown, three tool holders 4 are detachably attached to the support 2 , each having a cutting element 5 made of hard metal. like figure 1 As shown, the length of the cutting element 5 corresponds exactly to the length of the blade holder 4 , and here in the example shown a total of three blade holders 4 are provided with their cutting elements 5 which again exactly...

Abstract

The knife (1) has beam-shaped carriers (2) at which knife holders (4) are detachably fastened. The knife holders comprise cutting inserts (5) added to a continuous cutter. Length of the knife holders corresponds to length of the cutting inserts. A recess is provided at the knife holders. The cutting inserts are held in the recess in a form-fit manner and mounted in a load direction. The cutting inserts are soldered in the recess. Another recess is provided at the carrier. The knife holders are held in the knife holders in a form-fit manner.

Description

technical field [0001] The invention relates to a cutter, especially a cutter for a cord ribbon cutting machine. Background technique [0002] Cutters of the type described are commonly used for cutting strip-shaped materials. The cutter is either stationary or movable and interacts with another cutter to cut the strip of material therebetween. A basic field of application is the cutting of steel cord or fabric cord strips which are used in the field of tire manufacturing and which need to be cut by a corresponding steel cord cutter or fabric cord The machine cuts the coils into strips that can be individually handled and further processed. For this purpose, known cutters have a beam-shaped support on which a cutting element made of cemented carbide / hard metal is arranged and extends over the entire length of the support. This cutting piece is usually welded and is therefore non-detachably connected to the bracket. Depending on the length of the shearing machine, the len...
