An apparatus for conveying a web using an engagement cover comprising resilient looped pile engagement surface.

Web conveyance apparatus

A looped pile static reduction blanket or cloth, an apparatus including the looped pile static reduction blanket, and a technique to neutralize static and static patterns from a polymeric film surface during processing, to enable higher speeds and fewer defects during web transport and subsequent processing of wound film rolls, an apparatus including the looped pile static reduction cloth, and a technique to neutralize static from a polymeric shaped part during processing, to enable fewer defects. The looped pile static reduction blanket includes a static reduction engagement cloth that is resilient and can facilitate discharge of static from a web to ground before, during, and after contact with a charged web.

Articles for eliminating static electricity and methods for their use

The present application relates to an apparatus () for supporting sheet material during cutting by laser radiation comprising a support member () having a gold facing layer. A method for cutting sheet material using such apparatus is also defined.

Apparatus and method for laser cutting using a support member having a gold facing layer

A method for conveying a workpiece having a first major surface with exposed adhesive using at least one transport roll () having an engagement cover () having an engagement surface comprising looped filaments () that have a low surface energy wherein the work-piece () passes through engaging contact with the engagement surface such that at least a portion of the pressure sensitive adhesive () directly contacts the engagement surface wherein the pressure sensitive adhesive () is tacky when in contact with the engagement surface. Also an apparatus for carrying out the method.

Method for conveying adhesive-sided articles and apparatus for doing so

Laser conversion of multilayer optical film bodies comprising polyester and polycarbonate materials.

Laser cut articles

The disclosure generally relates to a looped pile film roll core used for winding a polymeric film, a method of winding film on the looped pile film roll core, and a roll of film that includes the looped pile film roll core. The disclosure describes an article and a process to reduce the core impressions created by the starting end of a web on the adjacent web layers next to the core. In one particular embodiment, the present disclosure can lead to a reduction in the amount and severity of such core impressions on a wound polymeric film, by reducing the amount of stress in adjacent layers of wound web.

Looped pile film roll core

The disclosure generally relates to a film roll core used for winding a polymeric film around, an apparatus for winding the polymeric film on the film roll core, a process of winding the polymeric film on the film roll core, and a rolled film on the film roll core. The disclosure more particularly relates to an open gap film roll core that is capable of reducing defects in wound films.

Open gap film roll core

The present disclosure describes a looped pile static reduction roller (), an apparatus () including the looped pile static reduction roller, and a technique to neutralize static and static patterns from a polymeric film surface during processing, to enable higher speeds and fewer defects during web transport. The looped pile static reduction roller includes a static reduction engagement cover () that is resilient and can facilitate discharge of static from the web to ground before, during, and after contact with a charged web ().

Static reduction roller and method for reducing static on a web

Laser cutting of multilayer optical film bodies comprising polyester and polycarbonate materials.

Laser cutting method and articles produced therewith

The provided containers () and methods provide for gravitational alignment of a plurality of stacked articles (), in which at least two edges () of each article align along inner walls () of a respective container. The aligning walls of the container are provided with low-friction surfaces to facilitate sliding and alignment of the articles. By aligning the stack of articles along two edges, the articles can be registered relative to not only each other but the container itself, thereby facilitating loading, unloading, and conversion of articles in the stack. Optionally, a compressible layer () opposing one or both of the aligning walls conforms and distributes stress along the non-aligning edges, thereby preserving registration of the articles relative to each other when the container is transported.

Storage container

A method for conveying a web using an engagement cover () comprising resilient looped pile () engagement surface. Also, web conveying roller () having an engagement cover thereon.

Web conveyance method and apparatus using same

The present disclosure describes a spreader roll () that can help spread webs laterally in a web processing operation, in particular to reduce or remove the presence of wrinkles or bagginess in the web. The spreader roll can be a reverse crown roll that is covered with a resilient material () to assist spreading the web to remove wrinkles. The surface curvature of the spreader roll () can be formed using layers of material such as a tape, to easily and readily approximate the shape of a reverse crown roll.

Adaptable web spreading device

A web tensioner, a web slitter, a method of tensioning a web, and a method of slitting a web are provided. A corrugated edge nip is used in the tensioner, the slitter, and the methods of tensioning and slitting. The corrugated edge nip can provide a crossweb tension to a suspended web or film in a web line. The corrugated edge nip can be used in conjunction with, for example, a rotary shear slitter to improve slit edge quality.

Corrugated edge nip

An improved contact nip roll, a method for assembling an improved contact nip roll, a system for nipping a web, and a method for nipping a web are provided. The improved contact nip roll integrates an inner softer core that can provide compliancy to web caliper variations, while rigid annular rings and a harder outer skin can maintain a uniform contact area.
