Abstract (en)
[origin: EP0329130A2] In a cutting apparatus for resin sheets which, in the form of a strip covered on at least one side by a foil, have been unwound from a roll and stripped from the foil, having a pneumatic drive for the fastening mean or fastening means for a cutting blade (3), a reduction in the energy used is obtained in that the cutting blade (3) is fastened to a piston slide (2) which is movable in a pneumatic cylinder (1) without a piston rod, which pneumatic cylinder is connected at both ends in each case via a reversing valve (5, 6) to a rechargeable compressed-air store (7), the capacity of which is adaptable to the amount of energy required for the cutting process. <IMAGE>
