ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to apparatus and methods for molding thermosetting polymers, and more particularly to apparatus and methods for molding thermosetting polymers onto substrates.
2. Background
The use of logos and other types of graphical display on articles of clothing is widespread. To date, the use of such graphic media has generally been limited to two dimensional flat display media such as, for example, silk screen. This presents many shortcomings to marketers of consumer goods. The present invention is directed to overcoming these shortcomings.
SUMMARY OF THE INVENTION
According to one aspect of the present invention, a method of molding bodies of thermosetting polymers onto substrates is provided that includes providing at least one supply of a polymer resin, positioning at least one substrate onto a heated surface, positioning a heated mold having at least one cavity onto the substrate, injecting a controlled amount of one of the supplies of polymer resin into each mold cavity to form at least one three dimensional body of polymer resin, and curing the three dimensional bodies of the polymer resin on the positioned substrate.
According to another aspect of the present invention, an article is provided including a substrate and at least one three dimensional body of a thermosetting polymer affixed to the substrate. The at least one three dimensional body of the polymer is affixed to the substrate by the process of: providing at least one supply of polymer resin, positioning the substrate on a heated surface, positioning a heated mold having at least one cavity onto the substrate, injecting a controlled amount of one of the supplies of polymer resin into each mold cavity to form at least one body of the polymer resin, and curing the bodies of polymer resin on the positioned substrate.
