Apparatus and method for rotary die X, Y, and theta registration
10717203 · 2020-07-21 · ·

A rotary die apparatus and method for three-axes registration error correction. The rotary die apparatus includes a rotary die for applying patterns to a strip of material, a sensor for sensing fiducials on the strip of material, actuators to adjust the rotary die, and a control system. The actuators adjust the rotary die along an X-axis extending along a direction of travel, along a Y-axis transverse of the direction of travel, and about a theta axis perpendicular to the X-axis and the Y-axis. The control system calculates a registration error based on a difference between an actual location or orientation of the fiducials and a desired location or orientation of the fiducials. Then the control system outputs control signals to the actuators to adjust the rotary die along the X-axis, along the Y-axis, and/or about the theta axis while the rotary die continues to rotate.

Perforating Apparatus and Method for Manufacturing A Shaped Line of Weakness

A perforating apparatus and method includes a longitudinal cylinder axis about which a cylinder rotates. At least one shaped anvil bead is disposed on the cylinder. The cylinder including an anvil block and an anvil bead form a cavity. The cavity may be used to control the debris produced during the perforating process. A blade is disposed on a support to cooperate in contacting relationship with the anvil bead. A web is perforated as the web passes between the rotating cylinder and the support and the blade operatively engages with the anvil bead. The debris may be controlled by being drawn into the cavity prior to the point where the blade engages the anvil and, subsequently, being expelled after the point where the blade engages the anvil bead.

A corrugated board plant includes a corrugated board production assembly for producing a double-face laminated web of corrugated board, and at least one cutting assembly arranged downstream of the corrugated board production assembly, which has a cross-cutting device for producing sheets from the double-face web of corrugated board, and is capable of producing at least one identification sheet from the double-face laminated web of corrugated board, which is different from the sheets. The corrugated board plant further has a stack depositing area arranged downstream of the cutting assembly to stack the sheets and the at least one identification sheet in such a way as to form a stack, which is identifiable by means of the at least one identification sheet, in particular for further processing.

Roll paper towel or tissue dispenser with spring dampening roll support

Dispenser apparatus for dispensing from a roll of sheet paper product supported by a support arm, a support member pivotally mounted on the support arm and a biasing structure operable to reduce the shock force in the sheet paper product by resisting pivotal movement of the support member.

Apparatus and method of manufacturing an elastic composite structure for an absorbent sanitary product

An apparatus for manufacturing an elastic composite structure for an absorbent sanitary product includes an anvil with weld pattern comprising at least one anchoring region and at least one deactivating region. The anchoring region includes anchoring welds that form anchoring bonds that fuse facing web layers and anchor elastic thread(s) in position relative to the facing web layers. The deactivating region includes a break bar constructed to sever the thread(s). A method of manufacturing the elastic composite structure includes positioning a tensioned elastic thread between web layers, fusing the web layers to form an anchored zone that includes anchoring bonds that fuse the web layers and anchor the tensioned elastic thread therebetween, and cutting the thread to form a deactivated zone between adjacent portions of the anchored zone that is free of tensioned threads. The method further includes fusing the web layers within the deactivated zone.
