The design of Broomfield transformer and foil winding machines, which optimizes the configuration of the various assemblies, results in effective and efficient material handling and tension and keeps machine size to a minimum.
Our transformer winding machines offer an extra heavy-duty, welded and machined steel vertical frame. This guarantees the accurate alignment of all payoffs and guides with the winding axis.
Operator Control Stations are located for accessibility and convenience during the machine operation. Switch labels available in several languages.
Dual Roller Coil Pressing is supplied as standard on most of our foil winding equipment. The dual roller design with a pivoting head, allows the rollers to change angle and spend more time on the corners. Interlocked with the E-Stop switch and up to 1,000 lbs (453.59 kg) of pressure.
Foil Tension is provided by urethane covered steel rollers positioned after the guide assembly. Several styles provide a large range of tensions. May be powered to move the foil forward.
Heavy Duty Tailstocks of swing-away or slide-away designs to meet the need for winding mandrel support.
Inflatable Air Shafts with pneumatic disk brakes, provide for de-spooling and tensioning insulation paper; may also have powered rewinds.
Foil Guide System, just prior to tensioning system, is simple, effective and maintenance free to provide consistent edge alignment of your foil.
Inflatable Air Shafts for foil supply rolls are switch controlled and supported on the frame end by two heavy duty flange bearings piloted into each side of the frame. Many different diameters to accommodate most supply roll core sizes. Electric Rewinds standard. Powered unwind or loose loop control is optional.
Tailstock Supports on the longer payoff shafts, swing down for easy supply roll loading and unloading and lock up into place.
Our foil and wire/foil winding machines are custom configured according to your specific coil requirements. We start with one of our standard winding machines models based on the speed, torque, and weight capacity requirements and add the features which tailor the winder to your needs.
Motor Equipment: 5 HP - 75 HP (3.73 kW - 55.93 kW) with AC Variable Frequency, AC vector, or DC regenerative motor drive controls.
Speed Reduction: Belt and pulley to a gear reducer for single speed machines, or multi-speed gearbox when ease of speed range change is required.
Spindle Speeds: Single speed machines for high torque, low speed applications: 0 - 30 rpm. Other speed ranges available.
Multi-Speed Machines for Wire & Foil: 0 - 30 rpm in lowest speed range typically; 0 - 380 rpm in highest speed range, depending on base machine selected. Higher speed ranges available.
Faceplates: 14" - 22" (355.6 mm - 558.8 mm) diameter models are used depending on the torque requirements
