Low friction materials prevent glass filament breakage

Fiberglass gathering shoes, pad wheels and wobble wheels are available in several grades of Metcar’s proprietary carbon-graphite material.

Carbon-graphite gathering shoes are used to guide and gather together individual glass filaments to form bundles of filaments called “fiberglass strands,” which are produced as part of the fiberglass manufacturing process. Metcar materials are low in friction, so they prevent breakage of the glass filaments. Materials that do not provide sufficient lubrication degrade, fray and even break the filament as it is pulled or guided through the process.
