Embodiment Construction

[0033] figure 1 It is a schematic top view of a cutting machine 1 of the present invention.

[0034] The cutting machine 1 comprises a belt knife 3 which is guided in a continuous manner. The band knife 3 is guided in opposite directions in a swivel zone 5 forming a cutting zone 7 .

[0035] The cutting machine 1 comprises a first deflecting device 9 and a second deflecting device 11 which respectively deflect and return said band knife 3 . The first and second deflection means 9, 11 deflect and return the belt knife 3 without a reverse bending cycle. That is to say: In the deflection devices 9 , 11 the band knife 3 is subjected to only a single bending cycle in each case.

[0036] The first deflection device 9 comprises a first cutter wheel arrangement 13 and a second cutter wheel arrangement 15 . The first cutter wheel arrangement 13 and the second cutter wheel arrangement 15 each comprise a cutter wheel 17 around which the band knife 3 is guided. The cutter wheel 17 of...

Abstract

In a cutting machine (1) with a rotating band blade (3), wherein the band blade (3) is moved in opposite directions in a circulation section (5) of the band blade (3) that forms a cutting section (7), and with a first and a second deflection device (9, 11) for redirecting and returning the band blade (3), provision is made that the first and the second redirection device (9, 11) each deflect the band blade without a reverse bending cycle and return it AGAin.

Description

technical field [0001] The invention relates to a cutting machine as defined in the preamble of claim 1 . Background technique [0002] Cutting machines, especially for cutting plastic and foam materials, are facing increasing demands on cutting quality, speed and stability. Said plastics and foams that need to be cut with a cutting machine become increasingly heavier and harder or resistant to shattering. Examples of said materials that need to be cut are not only found in the field of comfort foams, such as mattresses or furniture, but also rigid and semi-rigid PU, PE or PS foams that need to be cut, these foam materials are used in construction, Insulation of refrigerators or vehicles. [0003] For several years, belt knife machines have been used for cutting and separating foamed materials, etc. The belt knife runs on multiple knife deflection pulleys and spans freely in a cutting area with a length of up to 2.5 meters. Such cutting machines are known, for example, fr...
