Abstract

Extractor systems for extracting a flexible article of manufacture from a mold include an extraction roller, at least one track configured to support the extraction roller, and a trolley configured to carry the extraction roller from a first side of the mold toward a second, opposite side of the mold. Molding systems include a mold and an extractor system. Methods of extracting a flexible article of manufacture from a mold include separating a first platen and a second platen, positioning an extraction roller between the separated first and second platens, engaging the article of manufacture with a row of teeth positioned along the extraction roller, and rotating the extraction roller to wrap the article of manufacture about the extraction roller.

First claim

What is claimed:

1. A method for removing a flexible article of manufacture from a mold, comprising:
positioning an extraction roller adjacent to the flexible article of manufacture;
positioning at least an edge portion of the flexible article of manufacture on an exterior surface of the extraction roller; and
while maintaining contact between the edge portion and the exterior surface of the extraction roller, rolling the extraction roller to concurrently pull the flexible article of manufacture from at least a portion of a mold and completely wrap the flexible article of manufacture onto the extraction roller.

2. The method of claim 1 , wherein positioning at least a portion of the flexible article of manufacture on the extraction roller comprises grasping the edge portion of the flexible article of manufacture with the extraction roller.

3. The method of claim 1 , comprising moving the extraction roller over at least the portion of the mold while concurrently pulling the flexible article of manufacture from at least the portion of the mold and rolling the flexible article of manufacture to completely wrap the flexible article of manufacture onto the extraction roller.

4. The method of claim 3 , comprising moving the extraction roller between at least the portion of the mold and another portion of the mold that has been separated from at least the portion of the mold.
