Abstract
An assembly for chopping glass fibers including a cutter wheel having a plurality of radially extending blades and a cot wheel adjacent the cutter wheel. The cot wheel including an inner hub, an elastomeric ring mounted onto the inner hub for rotation therewith; and a retaining device fixably attached to the hub and engaging the elastomeric ring to resist separation of the elastomeric ring from the hub during rotation of the cot wheel.
Claims17
An assembly for chopping glass fibers, the assembly comprising:
- a cutter wheel having a plurality of radially extending blades;
- and
- a cot wheel adjacent the cutter wheel, the cot wheel comprising:
- an inner hub;
- an elastomeric ring mounted onto the inner hub for rotation therewith;
- and
- a retaining device fixably attached to the hub and engaging the elastomeric ring to resist separation of the elastomeric ring from the hub during rotation of the cot wheel.
4 more elements
A method of cutting glass fibers, the method comprising:
- bringing continuous glass fibers into engagement with a circumferential surface of a first rotatable member that includes an elastomeric ring mounted onto a cylindrical inner hub for rotation with the inner hub;
- rotating the first rotatable member to bring the glass fibers into contact with one or more cutter blades;
- cutting the glass fibers into discrete segments with the one or more blades;
- and
- mechanically holding the elastomeric ring in place relative to the inner hub.
