Abstract
Official abstract text for this publication.
A method and device for carrying out the method of converting waste such as thermally bonded polyester fiber to bed cushioning. Such waste is fed to a fiber lofter which forms lofted fiber. The lofted fiber is pneumatically transferring to a hopper, and from the hopper to an injector, the injector having a lofted fiber input nozzle and output nozzle, the output nozzle being a low friction tube.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of converting waste to bed cushioning, said method comprising: feeding said waste to a fiber lofter and lofting said waste therein to form lofted fiber; pneumatically transferring said lofted fiber to a hopper; and transferring said lofted fiber from said hopper to an injector, said injector comprising a lofted fiber input nozzle and output nozzle, said output nozzle comprising a low friction tube; wherein said low friction tube comprises polyethylene terephthalate. 2. A method of converting waste to bed cushioning, said method comprising: feeding said waste to a fiber lofter and lofting said waste therein to form lofted fiber; pneumatically transferring said lofted fiber to a hopper; and transferring said lofted fiber from said hopper to an injector, said injector comprising a lofted fiber input nozzle and output nozzle, said output nozzle comprising a low friction tube; wherein said low friction tube comprises polytetrafluoroethylene.
