A cutting apparatus for cutting a web within a frame includes a die cutter assembly including a cutting blade projecting from a cylindrical surface and a counter anvil including first and second ends journaled into the frame. The counter anvil is positioned below the die cutter assembly for receiving the web fed therebetween across a width of the frame. The cutting apparatus includes first and second outboard bearing assemblies positioned on the die cutter near the first and second opposing ends, respectively, and one or more inboard bearing assemblies positioned about the die cutter assembly and spaced inwardly from the outboard bearing assemblies. Each outboard bearing assembly is configured to control a spacing between the die cutter assembly and the counter anvil along the width of the frame. The cutting apparatus also includes one or more actuators positioned atop the frame in connection with the one or more inboard bearing.

A rotary cutting apparatus includes a frame movable in a first direction and a second direction that is opposite the first direction. The apparatus includes a cutting roll. The cutting roll is rotatably connected with the frame and configured to rotate about a first longitudinal axis. The apparatus includes an anvil roll. The anvil roll is rotatably connected with the frame and is configured to rotate about a second longitudinal axis. The first longitudinal axis is substantially parallel with the second longitudinal axis. The apparatus includes a first stationary member adapted to prevent movement of the frame in the first direction. The apparatus also includes a second stationary member connected with the frame. The second stationary member has a first configuration that prevents movement of the frame in the second direction. The second stationary member has a second configuration that allows movement of the frame in the second direction.

A rotary cutter system for cutting a web of material being feed into the rotary cutter at a press speed that includes a cutting cylinder, an anvil cylinder and a servo motor. The rotary cutter includes a controller that controls the speed of rotations of the cylinders. Control of the speed of cutting and anvil cylinders allows for the adjustment of the cut length of the material without having to adjust the position of knives in the cutting cylinder.

A method of cutting a continuous hollow tubular member having a fully expanded configuration with an outer diameter D, includes the steps of feeding the continuous hollow tubular member in the fully expanded configuration to a cutting station, cutting the continuous hollow tubular member into a plurality of hollow tubular members, each of which has a first flattened end and expanding the first flattened end of the plurality of hollow tubular members to the fully expanded configuration such that the first end of the plurality of hollow tubular members has an outer diameter D.

The present invention provides a perforating station comprising two or more discrete perforating stations, the stations synchronized with one another to cut a line of perforations across a web, such as a web of tissue paper, moving at high speeds. By providing two or more synchronized perforating stations the perforating station may increase the number of impacts per minute compared to prior art perforating devices.

Aspects of the present disclosure involve methods and apparatuses for cutting and removing trim from an advancing substrate. Particular embodiments of the apparatuses and methods disclosed herein provide for removal of continuous lengths of trim, and in some embodiments, discrete pieces of trim from an advancing substrate.

The disclosure concerns a rotary cutting apparatus having a frame and a die roll defining a first longitudinal axis and having a cutting member. The die roll is rotatably connected with the frame and configured to rotate about the first longitudinal axis. The rotary cutting apparatus further has a bearer ring connected with the die roll and an anvil roll defining a second longitudinal axis and having an outer radial surface. The anvil roll is rotatably connected with the frame and is configured to rotate about the second longitudinal axis. The bearer ring of the die roll is in contact with the outer radial surface. The anvil roll may be supported by at least one cam follower. The anvil roll may be axially removable from the frame via lateral translation along the second longitudinal axis.

Perforating equipment (111) for high speed transversal perforations of variable lengths on a continuous form (32) in movement is disclosed. The perforations are carried out by means of a perforating blade (39a) against a projecting profile (41a) of a blade contrast (39a) and blade and contrast servomechanisms (43, 128) for rotating a support for the blade and the blade contrast. The projecting profile (41a) has sectors with axial extensions different in dependence on their angular positions. The contrast servomechanism (128) is settable for selecting an angular phase of the blade contrast (39a), such to positioning, for the contrast with the blade, a sector of the projecting profile (41a) having axial extension equal to the requested length of the perforation (P). The blade contrast can be constituted by a hollow cylinder (113) rotatable around a support shaft (114) as a radial air bearing of pneumostatic type.
