Claims51
A method of processing carpet, fabric or other flexible sheet material having a face layer and at least one backing layer, the method comprising:
- conveying the carpet, fabric or other flexible sheet material along a platform;
- urging the carpet, fabric or other flexible sheet material into contact with the platform;
- and
- simultaneously abrading a surface of the carpet, fabric or other flexible sheet material.
A system for processing carpet, fabric or other flexible sheet material having a face layer and at least one backing layer, the system comprising:
- a platform upon which the carpet, fabric or other flexible sheet material is conveyed;
- an abrasive device located adjacent the platform to abrade a surface of the carpet, fabric or other flexible sheet material as the carpet, fabric or other flexible sheet material passes beneath the abrasive device;
- and
- a screed device located adjacent the platform and upstream of the abrasive device to urge the carpet, fabric or other flexible sheet material into contact with the platform as the surface of the carpet, fabric or other flexible sheet material is simultaneously abraded by the abrasive device.
A system for abrading a substrate, the system comprising:
- an abrasive device positioned to abrade a surface of the substrate as the substrate is conveyed adjacent the abrasive device, the abrasive device including
- a cylinder having a first end, a second end and an exterior surface extending therebetween;
- an abrasive media sheet anchored at the first end of the cylinder and wrapped around the exterior surface;
- and
- an attachment device coupled to the abrasive media sheet and the second end of the cylinder, the attachment device including a biasing element arranged to urge the abrasive media sheet into a taut condition around the exterior surface of the cylinder.
A method of preparing an abrasive device to abrade a surface of a substrate, the method comprising:
- attaching a first end of an abrasive media sheet to a first end of a cylinder;
- wrapping the abrasive media sheet around an exterior surface of the cylinder;
- and
- attaching a second end of the abrasive media sheet to a second end of the cylinder whereby a bias is applied to the second end of the abrasive media sheet to urge the abrasive media sheet into a taut condition around the exterior surface of the cylinder.
