ABSTRACT:
Disclosed is a removable edge guard for installation on an edge of a vehicle door or the like. The edge guard is a composite of self-supporting polymeric materials. A protector portion is formed from a first polymeric material and has a bumper section and a planar section. A base portion is formed from a second polymeric material more rigid than the first polymeric material. The base portion and the planar section of the protector portion together define a U-shaped channel to receive the edge of the vehicle door or the like. The base portion is extrudably joined to the planar section of the protector portion at the closed end of the U-shaped channel. A retention fin is extrudably joined to the base portion at the open end of the U-shaped channel. The retention fin is formed from the first polymeric material. The retention fin projects into the U-shaped channel toward the planar section of the protector portion. The retention fin and planar section cooperate to retain the edge of the vehicle door or the like received in the U-shaped channel. Also disclosed is a method of manufacturing the removable edge guard by co-extruding a first and second polymeric material through a single extrusion die to form a composite polymeric extrudent having the desired profile. The desired profile is maintained by a series of vacuum sizing plates until a memory is established by cooling the composite polymeric extrudent in a combination water bath and water wash. The composite polymeric extrudent is then cut into predetermined lengths to form the final composite polymeric edge guard.
