METHOD OF PRODUCING A COMPONENT OF A DEVICE AND METHOD OF CLEANING PARTICLES FROM A MAJOR SURFACE OF A FLEXIBLE WEB SUBSTRATE OF INDEFINITE LENGTH

摘要

The method of the present invention includes the steps of providing a flexible web substrate (e.g., a polymeric flexible web substrate) that forms at least a portion of a component of the device, Wet-out and cover all or a substantial portion of the major surface on one or both sides of the flexible web substrate with a flowable polymeric material, and solidifying the polymeric material to form one side or both sides of the flexible web substrate, And forming a single cleaning layer on the major surface of both sides. The present invention can be used in a continuous in-line manufacturing method. In an application of the present invention in which the flexible web substrate does not form a component of the device, the present invention provides a method for cleaning particles from flexible webs of undetermined length. Each of the cleaning layers creates a significant adhesive bond to the major surface that is easily removable without damaging or leaving significant residue of cleaning layer material on the primary surface. A significant number of particles on these major surfaces are trapped by the cleaning layer and can be removed using it.
