ABSTRACT:
Apparatus comprising a pair of endless conveyors arranged on an aligned line with a space therebetween, one of which runs intermittently and the other continuously; a lifter arranged between the conveyors to freely move up- and downwards; a gripper arranged above the lifter to freely close and open its claws; and a cutter arranged immediately below the gripper and attached freely swingable and integral to a cutter plate being freely movable in a direction perpendicular to the direction at which a cylindrical package is conveyed; wherein the front end of the package is brought and stopped above the lifter by means of the intermittently running conveyor; the front end of the package is a little lifted and pressed by the lifter against the claws of the gripper; the gripper closes its claws to grip the packaging material of the package at the upper side thereof and then to hang the package when the lifter returns to its original position; the tip of the cutter is horizontally thrust into the packaging material below the gripped portion thereof; following the opening of the closed claws of the gripper, the intermittently running conveyor is re-driven to further convey the package; and the cutter is swung synchronously with the forward movement of the package to cut out the packaging material along the upper side of the package.
