Abstract:
1. A method for producing a carpet mat by injection molding, comprising: providing an injection mold including a cavity and a complementary core, each defining a portion of a mold recess for accommodating the finished carpet mat; providing said cavity with a surface having at least one vacuum opening bordered by a peripheral retaining barrier; applying vacuum to said cavity; inserting a sheet of carpet into said mold recess of said cavity and against said surface so that said carpet is held in said recess by said vacuum; closing the cavity and core, thus sealing said mold recess; injecting a flowable supply of plastic into said mold recess; opening said mold after a specified period, allowing said plastic to at least partially solidify; and providing sufficient vacuum so that said carpet sheet is compressed within a space defined by said barrier.
