the carpet blank the carpet blank is shown alone prior to tpr molding in fig2 and 7 and can also be seen in partial cross section in fig3 and 8 the carpet blank has a fibrous top layer 106 undercoated by a plastic layer 108 perforations 112 pass through both layers and are arranged in a pattern around the carpet which is selected to correspond with the rubber areas 116 and 117 of the tpr base fig3 through 5 depict the molding sequence through a line of perforations taken at line 4 4 of fig1 and line 3 3 of fig2 fig8 through 10 depict the molding sequence through both perforated and non perforated areas taken at line 9 9 of fig6 and line 8 8 of fig7 the exemplary molding process includes and may be considered a variation of existing insert injection molding except with improvements in traditional insert injection molding a component is positioned in the open mold prior to closing the mold and injecting molten plastic resin around the component to at least partially encapsulate it and bond it to the plastic as the plastic cures and hardens the present arrangement and process advances the bonding while providing significant structural function and aesthetic advances referring to fig3 and 8 the carpet blank is positioned within the top.
