Abstract
A seal member has a sealing portion, length control members and a heat activated member securing the length control members to the sealing portion. The length control members prevent excessive elongation of the sealing members during installation when the sealing member is applied by automated equipment.
Claims19
A sealing weather strip comprising:
- a means for sealing a door, window, body or the like, said sealing means being elongated, defining a longitudinal axis and formed from an elastomeric material, said sealing means including a surface for coupling said sealing means along said longitudinal axis;
- one or more length control members positioned on said coupling surface along said longitudinal axis;
- and
- heat activated means for coupling to said coupling surface, said heat activated means covering said longitudinal length control members and being heated to bond to said surface such that said heat activated means fixedly secures to said surface to form a laminate weather strip.

The weather strip according to claim wherein said one or more length control members are polyester strands.
A method of forming a weather strip comprising the steps of:
- providing an elongated extruded elastomeric sealing member, said member defining a longitudinal axis and having a surface for coupling said sealing member, one or more length control elements and a heat activated member;
- positioning said one or more length control members longitudinally along said axis on said coupling surface;
- positioning said heat activated member on said coupling surface such that said one or more length control elements are sandwiched between said heat activated member and said coupling surface;
- heating said heat activated member to affix said heat activated member and said one or more length control members to said coupling surface;
- and
- forming a laminate weather strip with controlled elongation characteristics.
