Eight Working Station Coil Winding Machine
Dec 20, 2016

winding machine or winder is a machine for wrapping string, twine, cord, thread, yarn, rope, wire, ribbon, tape, etc. onto a spool, bobbin, reel, etc.

Winders are used heavily in textile manufacturing, especially in preparation to weaving where the yarn is wound onto a bobbin and then used in a shuttle. Ball winders are another type of winder that wind the yarn up from skein form into balls. Ball winders are commonly used by knitters and occasionally spinners.

Winders have a center roll (a bobbin, spool, reel, belt-winding shell, etc.) on which the material is wound up. Often there are metal bars that travel through the center of the roll, and are shaped according to their intended purpose. A circular bar facilitates greater speed, while a square bar provides a greater potential for torque. Edge sensors are used to sense how full the center roll is. They are mounted on adjustable slides to accommodate many different widths, as the width increases as the center roll is filled. The sensitivity of the sensor depends on the required speed of operation.
