A process and apparatus for insertion of a stuffer plug (18) within a hollow section of a automotive weatherseal extrudate (10) is provided which operates by insertion of a needlelike section (20) of a dispenser unit through a wall of the extrudate into the hollow section. A stuffer plug precursor is then injected or inserted into the hollow section and the needle-like section of the dispenser is removed. The stuffer plug precursor (22) then forms a stuffer plug (18) within the hollow section. Preferably, the stuffer plug is a two part polyurethane which reacts chemically to form a polyurethane foam stuffer plug (18) within the hollow section. An easier method for establishing a stuffer plug (18) within an extrudate (10) is provided.
An on-line process for introducing a stuffer plug into a hollow section of an extrudate comprising:
An apparatus for the on-line provision of a stuffer plug within a hollow section of an extrudate, which apparatus comprises a dispenser assembly having a needle-like section and a stuffer plug precursor supply means for supplying stuffer plug precursor material to said dispenser assembly, wherein said needle-like section is capable of being at least partially inserted, through the wall of the extrudate, into a hollow section within said extrudate so that said stuffer plug precursor material can be fed through said needle-like section of said dispenser into said hollow section in an operative position, and wherein said needle-like section is capable of being substantially removed from the hollow section within said extrudate in an inoperative position.
