- This machine makes hose continuously by criss-crossing strands and wrapping them around a cylindrical core (mandrel) which is pulled through the center of the machine. The strands (of fiber, plastic, etc) are on spools, and these spools rotate on a ring concentric to the mandrel, winding the fibers around the mandrel as the mandrel is pulled through the ring. Half of the the spools are traveling clockwise, and half counter clockwise, weaving in between each other to create the criss-crossed pattern.
