FIELD: packing industry.SUBSTANCE: invention is designed to remove an end sealing part of a compressible type package, in which the end sealing part closes a channel limited with two opposite side walls of the package. The device comprises a cut disc installed as capable of rotation around the first axis of rotation with sharpened teeth along circumference, forming a cutting edge, and a support disc installed as capable of rotation around the second axis of rotation, which is parallel to the first axis. Besides, the cut disc has a peripheral surface stretching in radial direction, which partially forms the cutting edge of the disc, and the support disc has a surface stretching in radial direction and facing the first surface of the cut disc. At the same time the peripheral surface of the cut disc and the surface of the support disc stretching in radial direction and facing the peripheral surface of the cut disc are arranged in contact with a closure to form a place of clamping for cutting.EFFECT: invention provides for higher quality as a result of reduced spreading of packaging material and reduced cold welding of channel walls.14 cl, 13 dwg |
