Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
156 words
A method of forming a laminated ski comprising the steps of: (a) providing a ski mold having a portion thereof which supports individual layers of the ski during the forming operation; (b) vacuum forming a layer of plastic film onto said portion of said ski mold; (c) positioning various components of the ski on said vacuum-wrapped portion of said ski mold, at least some of said components being pre-coated with thermo-setting adhesive, until a ski pre-assembly has been formed on the mold; (d) subjecting said mold and ski pre-assembly to heat and pressure to form a contoured ski pre-assembly and set the adhesive under conditions wherein an excess of the adhesive is expressed from the ski pre-assembly into contact with said plastic film layer; (e) separating said mold from the contoured ski pre-assembly whereby said plastic film layer adheres to said contoured ski pre-assembly; and (f) removing said plastic film layer from said contoured ski pre-assembly.
Claim 2
Independent Claim
156 words
A method of forming a laminated ski comprising the steps of: (a) providing a ski mold having a portion thereof which supports individual layers of the ski during the forming operation; (b) vacuum forming a layer of plastic film onto said portion of said ski mold; (c) positioning various components of the ski on said vacuum-wrapped portion of said ski mold, at least some of said components being pre-coated with thermo-setting adhesive, until a ski pre-assembly has been formed on the mold; (d) subjecting said mold and ski pre-assembly to heat and pressure to form a contoured ski pre-assembly and set the adhesive under conditions wherein an excess of the adhesive is expressed from the ski pre-assembly into contact with said plastic film layer; (e) separating said mold from the contoured ski pre-assembly whereby said plastic film layer adheres to said contoured ski pre-assembly; and (f) removing said plastic film layer from said contoured ski pre-assembly.
Claim 3
Independent Claim
146 words
A method of forming a laminated ski comprising the steps of: (a) providing a ski mold having a portion thereof which supports layers of components which make up the ski, said portion being covered by a plastic film layer vacuum formed onto said ski mold; (b) building a laminated ski pre-assembly on said portion of said mold by properly positioning all of the components of the ski in layered fashion on said mold, at least some of said components being pre-coated with a settable adhesive material; (c) imparting to the laminated ski pre-assembly the proper shape and contour of a ski while concurrently causing said plastic film layer to adhere to the laminated ski pre-assembly; (d) stripping the shaped and contoured ski pre-assembly and the plastic film layer adhering thereto away from said mold; and (e) removing the adhering plastic film layer from the ski pre-assembly.
Claim 4
