Roll Winder
A winding machine or winder is a machine used for wrapping string, twine, cord, thread, yarn, rope, wire, ribbon, tape, etc. onto a spool, bobbin, reel, etc.
Mechanism of winders
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.
Types of winders
Winding machines are classified based on the materials they are winding; some major types are:
• Coil winding machine
• Film winding machine
• Rope winding machine
• Paper winding machine
• Foil winding machine
• Roll slitting machines
• Spool winding machine
• Cop winding machine
Generally, plastic film is extensible (stretchable) material, most other materials can be considered non-extensible. Rolls may be wound by applying drive torque at its center or its surface. As a result the two major categories of winders are:
• Center Winders
• Surface Winders
Winder drives are designed to improve the wound package and eliminate material breakage.

Application Overview:
Winding is a procedure to take up and package material in roll form for more efficient handling or in preparation for a subsequent operation. In a typical industrial application, a winder is employed to roll up a continuous or limited length of material such as wire, paper, film, metal or textiles. The winder and finished roll are referred to by different names in different industries.
