Foam product with an insert and its method of manufacture

摘要

A product, such as an insole (21, 22) or the like, is formed in a mold (20) having mold cavities (26, 27) therein. A porous insert (33, 34) is placed in the cavities (26, 27) and a foamable material (35) is introduced into the cavities (26, 27). When the material (35) cures, it impregnates the inserts (33, 34) which makes them more rigid. The resulting insoles (21, 22) thereby have a portion made up entirely of foam (35) and a portion made up of the insert material (33, 34) rigidified by the foam (35).

主权项

1. A method of making a product having a length in a mold having a cavity with a peripheral configuration comprising the steps of placing a porous material onto a portion of the peripheral configuration of the cavity, inserting a foamable material in the mold, and allowing the foamable material to cure while at the same time completely impregnating the porous material so as to render the porous material more rigid and to become integral with the foamable material while maintaining a cushioned product, wherein the foamable material is coextensive with and extends in length beyond the porous material.
