Abstract
The present invention relates generally to the reclaiming of carpet waste material. More particularly, the invention relates to a method and system for reclaiming carpet components such as yarn, tufting primary, binder, and secondary backing from post-industrial and post-consumer carpet waste in a substantially continuous flow process.
Claims23
A method of reclaiming secondary backing materials, primary backing materials, and face materials, from carpet waste pieces, comprising:
- selectively feeding carpet waste pieces into a component waste separation system comprising:
- a shearing subsystem comprising a band blade shearing subsystem having an endless moving band blade that is configured to contact the incoming carpet waste pieces to remove or otherwise separate the face materials from the primary backing material of the carpet waste pieces;
- and
- a shearing infeed subsystem comprising a drawbridge conveyor that is configured to be movable about and between a substantially horizontal operation position and a substantially vertical maintenance position, a distal end of the drawbridge conveyor being selectively positioned with respect the band blade of the band blade shearing subsystem to remove or otherwise separate the face materials at a desired height from the primary backing material of the carpet waste pieces.
