Abstract: In a plural component foam dispensing apparatus there is provided an easily removable and replaceable combination nozzle-mixing chamber that is formed of a low friction, slightly deformable material with a first front contact surface against which is applied force to load the second rear contact surface against the contact surface of the nozzle seat to securely hold the combination nozzle-mixing chamber in place. The core of the combination nozzle-mixing chamber is not axially restrained on each end.

Abstract: A method for manufacturing laminated skis wherein the molds in which the skis are built are vacuum wrapped with a plastic film prior to the placement of the ski components in the molds. The adhesive-coated ski components are then placed in the vacuum-wrapped molds in proper fashion. The mold-component assembly is then placed in a press when the ski is formed under pressure and heated so as to set the adhesive. The ski is then stripped off of the mold, the plastic wrap adhering to the ski and leaving behind a clean mold. The plastic wrap is then removed from the ski.
