Abstract
A process and apparatus for insertion of a stuffer plug () within a hollow section of a automotive weatherseal extrudate () is provided which operates by insertion of a needlelike section () 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 () then forms a stuffer plug () within the hollow section. Preferably, the stuffer plug is a two part polyurethane which reacts chemically to form a polyurethane foam stuffer plug () within the hollow section. An easier method for establishing a stuffer plug () within an extrudate () is provided.
