摘要：A method and apparatus for continuous cold cutting or slitting of a flat materialwherein the flat material is subjected to a first step of partial-shearing or penetration in azigzag state to a controlled depth of penetration, and subsequently to a second step offlattening, thus forcing the penetration formed in the material back to substantially theoriginal thickness of the material, thereby to perform complete severing or slitting thematerial having no burrs formed during the operation. The first working action isobtained from feeding of the flat material into the controlled spacing of opposing pairsof cutter discs so that there occurs partially shearing or penetration in the flat materialunder an optimally predetermined interfering action by the opposing pairs of cutter discsinto the material when it engages therewith. The second working action is obtained fromthe insertion of thus partially-sheared or penetrated material into the spacing optimallypredetermined between an opposing pair of rolls having a flat cylindrical surface so thatthere occurs flattening action by the opposing pair of rolls over the both surfaces of thematerial when engaged therewith. The cutter discs and flattening rolls are controllablydriven in synchronism.
