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).

L'invention concerne un bourrelet de poil (20) ayant une ailette solidaire, que l'on obtient en enveloppant un matériau pour ailette autour d'un mandrin ou d'une bande (14) à courroie, en enroulant le matériau de poil autour du matériau pour ailette et de la bande (14), en fixant une paire d'éléments d'appui au matériau de poil sur les bords opposés de la bande et en coupant ensuite le matériau de poil afin de produire simultanément deux bourrelets de poil. Les éléments fixes et mobiles peuvent être utilisés pour faciliter la coupe et produire des ailettes au-dessus des bourrelets de poil 20.
