Hot punch process for producing a perforated retroreflective trim

摘要

A method for producing a perforated retroreflective trim is disclosed, wherein the method includes the steps of: providing a retroreflective trim comprising a retroreflective material and having first and second sides; forcing a plurality of rigid members through the retroreflective trim to remove a plurality of portions of the retroreflective trim to provide a plurality of openings through the retroreflective trim extending between the sides of the retroreflective trim, thereby forming a perforated retroreflective trim, wherein the rigid members are heated when forced through the retroreflective trim. The disclosed perforated retroreflective trim includes: a retroreflective film of material including opposite first and second sides;a plurality of holes or openings through the retroreflective film of material and extending entirely through the film of material between the first and second sides formed by the removal of a plurality of portions of the retroreflective film,wherein in the process a portion of the retroreflective film around the openings formed in the retroreflective film through melting or softening is partially drawn through and into the openings.
