Abstract
Systems and methods utilizing stationary and/or moveable cutting components provide limited interference with web processing operations, such as pad spin and pitch alteration. Heat, laser, fluid, or mechanical cutting operations may be used, including respectively, a heated element (e.g., wire, ribbon, bar, or embossing or perforating element) that may be triggered inductively, water or steam jets, or improved knife/anvil cooperation.
Claims19
A system for processing a web of material, the system comprising:
- a wheel configured to rotate about an axis;
- a traveling body coupled to the wheel and configured to carry a web;
- and
- a cutting loop coupled to the traveling body and configured to receive electrical current, wherein the web of material is disposed adjacently to the cutting loop;
- wherein the cutting loop is configured to:
- receive the electrical current in a web alteration zone to heat the cutting loop;
- and
- contact the web of material in the web alteration zone to alter the web of material from a first condition of the web to a second condition of the web.
A system for processing a web of material, the system comprising:
- a rotatable puck support assembly;
- a puck coupled to the rotatable puck support assembly and configured to carry a web;
- and
- a cutting loop coupled to the puck and configured to receive electrical current, wherein the web of material is disposed adjacently to the cutting loop;
- wherein the cutting loop is configured to:
- heat to a cutting temperature in a web alteration zone;
- and
- contact the web of material in the web alteration zone to sever a pad from the web.
A system for processing a web of material, the system comprising:
- a vacuum system;
- a traveling body configured to carry a web, the traveling body comprising:
- a vacuum chamber fluidly communicating with the vacuum system;
- and
- a plurality of vacuum holes in a surface of the traveling body, the plurality of vacuum holes fluidly communicating with the vacuum chamber;
- wherein the vacuum system is configured to create a vacuum in the vacuum to cause the traveling body to carry the web;
- and
- a fluid jet system comprising:
- one or more fluid jets;
- and
- a fluid collection system;
- wherein the web of material is disposed between the one or more fluid jets and the fluid collection system;
- wherein the one or more fluid jets are configured to operate cooperatively with the fluid collection system in a web alteration zone to generate a cutting fluid;
- and
- wherein the cutting fluid contacts the web of material in the web alteration zone to alter the web of material from a first condition of the web to a second condition of the web.
