    摘要: In a web cutting device, a web held by pads has a section between mutually adjacent pads that is sandwiched between an anvil and a blade edge of a cutter and cut. A stop member is fixed in a rotating member. The cutter is biased by a biasing member and comes in contact with the stop member. The stop member obstructs travel by the cutter towards the outside in the radial direction of the rotating member, when the cutter comes in contact with the stop member. The biasing member biases the cutter to the outside in the radial direction of the rotating member and causes the cutter to come in contact with the stop member, by using a predetermined biasing force, and allows the cutter to retreat when the reaction force acting on the cutter is greater than the predetermined biasing force.

    摘要: An insert assembly is received in a recess on the outer surface of a rotary cutting cylinder. The insert has a hole for a slug ejector pin which is slidingly engagable with the insert. The hole is arranged on the insert to communicate with a through hole in the recess that extends into the interior of the cylinder. When the slug ejector pin is inserted in the pin hole, the pin proximal end is received in the recess hole adjacent to the compressible core and the pin distal end projects from an outer surface of the insert. When the pin is assembled with the insert and the insert is assembled with the cylinder, the pin proximal end operatively engages the compressible core when the pin retracts into the pin hole of the insert and the pin proximal end operatively engages the insert when the pin projects from the pin hole.

    摘要: A cutter roll and an anvil roll, with which it is possible to control deformation in the axial direction, and a rotary cutter having the same. A roll 101, 210 for a rotary cutter includes: a barrel portion having a circumferential surface and a pair of end surfaces located respectively at opposite ends of the circumferential surface; a pair of first depressions 113, 213 having a ring shape or a cylindrical shape and located respectively at the pair of end surfaces of the barrel portion, the pair of first depressions each having a depth direction that is parallel to an axis of the barrel portion; a pair of first bearings 152, 252 located respectively in the pair of first depressions and being in contact with outer walls of the first depressions; and a pair of first bearing boxes 156 located on an outside of the pair of first depressions and having support portions 151b, 251b to be in contact with a support frame or a pressure mechanism, the pair of first bearing boxes supporting the respective bearings.
