Filament winding machines place or wind continuous fibers on a mandrel surface in a precise geometric pattern. The mandrel is rotated while a delivery mechanism precisely positions the fibers on the ...
A fan cools the filament just before it goes onto the spool. The same stepper motor is used for both stages of the process. We like the simplicity of this machine compared to a conventional screw ...
In concept, any machine that creates filament is pretty straightforward. Melt pellets and push them out of a nozzle. Cool the filament and wind it up. Easy, right? But, of course, the problems are ...
