Pile weatherstripping ( 20 ) having an integral fin is made by wrapping a fin material around a traveling mandrel or band ( 14 ), winding pile material around the fin material and the band ( 14 ), attaching a pair of backer elements to the pile material along opposite edges of the band, and then cutting the fin material and the pile material to produce simultaneously two pile weatherstrips. Stationary and traveling elements may be employed to facilitate cutting and produce fin above the pile weatherstrips ( 20 ).
