Reels, spools and spooling

Protecting your wire. . . On any continuous wire drawing machine, the wire has to be either to be wound on the reels, spools or take-up drums. Even the payoff equipment can be a source of feeding of wire. This equipment acts as the hands of the machine, with high drawing speeds and a series of blocks and panel lines and the productivity levels can be enormous.

Much of the capital cost and the materials handling of a wire drawing system lies in payoffs, take-up equipment, dead block coilers, etc. This equipment has become more important with the increase in the drawing speed and the machine running with modern AC variable frequency drive control panels. Of the many products handling wire, perhaps the most misunderstood group of machines is spoolers. Before selecting the spooling machine as a manufacturer we have to consider maximum time allowable for starting and stopping, along with special features such as tension requirements and range of spool sizes, layer winding, random winding, spool mounting, etc. These spools can vary from smaller size to heavier sizes for thicker wires. Even double spoolers are gaining popularity because of the elimination of down time of equipment. A double spooler is capable of transferring the wire from the full spool to an empty spool automatically without stopping, and during the transfer the wire will be sheared. The main advantage of a dead block coiler is to get heavy continuous wire coils and drawing the wire uninterrupted on the wire drawing machine. The use of dead block permits coils to be removed with complete safety regardless of wire speed or coil weight without interrupting the operation of the drawing machine. Drum pack coilers are used for packaging various types of high and

low carbon wire in hard cardboard/fibre drums. Since this innovation, it is easy to handle and provides protection for the wire. The grades of wire which often require use of drum pack coilers are welding wire, stapling, stitching wire and other gauges of wire which require production in transportation. The drum pack unit is in conjunction with the wire drawing machine and operates at the same speed as the drawing equipment.
