The present method comprises providing a flexible web substrate (e.g., polymeric flexible web substrates) that forms at least part of a component of a device, coating so as to wet-out on and cover all or a substantial portion of a major surface on one side or both sides of the flexible web substrate with flowable polymeric material, while the flexible web substrate is moving in a down-web direction, and solidifying the polymeric material so as to form one cleaning layer on the major surface of one side or both sides of the flexible web substrate. The present invention can be utilized in a continuous in-line manufacturing process. In applications of the present invention where the flexible web substrate will not form a component of a device, the present invention broadly provides a method for cleaning particles from a flexible web of indefinite length. Each cleaning layer forms a substantially adhesive bond to the major surface that is readily removable without damaging or leaving a substantial residue of cleaning layer material on the major surface. A substantial number of the particles that were on this major surface are captured by and removable with the cleaning layer.

Method of producing a component of a device, and the resulting components and devices

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 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.

A center-fed single cavity slot die () for coating particulate suspensions without creating the coating defect known as center banding. The die has a flow obstruction device () located in the die cavity () in a position such that the flow obstruction device blocks undisturbed straight-line flow of coating composition from the feed inlet to the die coating slot. Also, a coating process that employs the disclosed coating die. Types, shapes, sizes, and compositions of particles that may be used, and viscoities and particle concentrations of the coating composition which may be used.

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 ().
