System and method for reclaiming waste carpet materials

摘要

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.

主权项

1. A system for reclaiming secondary backing materials, primary backing materials, and face materials from carpet waste pieces, comprising:
a component separation system, comprising:
a shearing infeed subsystem comprising a drawbridge conveyor that is configured to be movable about and between a substantially horizontal operational position and a substantially vertical maintenance position; anda shearing subsystem comprising a band blade system having an endless moving band blade that is configured to contact the incoming carpet waste pieces to separate the face material from at least the primary backing material of the carpet waste pieces;wherein, when the drawbridge conveyor is positioned in the substantially horizontal operational position;
the shearing infeed subsystem selectively feeds incoming waste carpet pieces to the shearing subsystem; andthe distal end of the drawbridge conveyor is selectively positionable with respect the band blade of the band blade system such that the face materials can be separated at a desired height from at least the primary backing material of the carpet waste pieces.
