Abstract
A weatherstrip and method for making the weatherstrip for use in sealing the space between fixed and movable members. The weatherstrip comprises a backing strip having a sealing body affixed thereto to form a sealing assembly, and a barrier fin secured at one edge to the sealing assembly. The barrier fin comprises a pair of leafs transverse to the backing strip. A longitudinal fold line in each leaf defines a leaf portion extending outwardly from the backing strip and toward the other leaf portion. The leaf portions are sealed together to form a hollow fin of substantially diamond-shaped cross section.
Claims17
A pile weatherstrip having a diamond-shaped barrier fin comprising:
- a backing strip;
- at least one sealing body having one surface portion thereof fixed to one face of said backing strip and extending longitudinally thereof and cooperating therewith for forming a sealing assembly, said sealing body extending from said one face and having an opposite free surface portion;
- and
- a flexible barrier fin fixed adjacent one edge portion thereof to said sealing assembly, said fin comprising a pair of longitudinally extending leafs transverse to said one face, and a first fold line in each leaf defining a leaf portion extending outwardly from said backing strip and toward said other leaf portion, said leaf portions further being sealed together along a seal line to form a hollow fin of substantially diamond-shaped cross section.
A method for manufacturing a pile weatherstrip having a substantially diamond-shaped hollow barrier fin comprising the steps of:
- securing at least one sealing body to a backing strip to form a sealing assembly;
- folding a film to form a bottom fold and a pair of up-standing leafs and securing the folded film to the sealing assembly;
- folding the leafs intermediate their ends so that free end portions of the leafs are moved toward one another;
- sealing the free end portions of the leafs together along a seal line to form a substantially diamond-shaped hollow barrier fin;
- and
- cutting the leafs along the seal line to remove the excess free ends of the free end portions of the leafs whereby a weatherstrip is formed having a substantially diamond-shaped hollow barrier fin.

- securing at least one sealing body to a backing strip to form a sealing assembly;
- folding a film to form a bottom fold and a pair of up-standing leafs and securing the folded film to the sealing assembly;
- folding the leafs intermediate their ends so that leaf portions are moved toward one another;
- sealing the leaf portions together along a seal line to form a substantially diamond-shaped hollow barrier fin connected to free end portions of the leafs;
- and
- folding at least one of the free end portions over the sealing body whereby a weatherstrip is formed having a substantially diamond-shaped hollow barrier fin.
