Continuous filament winding

Attaching a Pullwinding machine (Figure 21.67) to a pultrusion machine enables a combination of pultrusion and continuous filament winding to be accomplished.

Staple and Tow. The same extmsion technology that produces continuous filament yam also produces staple and tow. The principal difference is that spinnerets with more holes are used, and instead of winding the output of each spinneret on an individual package, the filaments from a number of spinnerets are gathered together into a ribbon-like strand, or tow. A mechanical device uniformly plaits the tow into a carton from which it can be continuously withdrawn without tangling.
