Abstract
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).
Claims34
A method of continuously manufacturing a pile weatherstrip having an integral fin, the method comprising the steps of:
- wrapping a fin material around a traveling band so as to provide excess fin material proximate at least one side of the band;
- winding a pile material around the fin material and the band;
- attaching a backer to the pile material;
- and
- cutting the fin material and the pile material to produce the pile weatherstrip.
A machine for manufacturing a pile weatherstrip having an integral fin, the machine comprising:
- a traveling band;
- a guide for wrapping a fin material around the band so as to provide excess fin material proximate at least one side of the band;
- a winding station for winding a pile material around the fin material and the band;
- an attachment station for attaching a backer to the pile material;
- and
- a slitter station for cutting the fin material and the pile material to produce the pile weatherstrip.
