Plug-and-Play Motorized Puller Assemblies

Motorized puller assemblies from Versa Machinery (Elkhart, IN) include all components for out-of-the-box productivity for a wide variety of downstream handling requirements.

Available in pinch wheel or caterpillar designs, pullers are mounted on a 12-in-by-14-in base plate for easy positioning of feed materials, include a choice of AC or DC motor and drive, and come with a remote operator control station (OCS) that can be mounted wherever desired. A wide variety of speed ranges is available, with pinch roll or belt materials to suit a broad range of product requirements.

The OCS includes pushbuttons for start, stop, and emergency stop as well as a 10-turn potentiometer with turns counter for speed control. Digital speed indicator and 115-volt input are standard; other voltages available as options.

The assemblies are equipped with a hand wheel to adjust the belt gap, which opens and closes around a constant centerline. Optional pneumatic operation of the belt booms along a constant centerline allows control of the pressure applied to the product being pulled and makes repeatable setup almost instantaneous.

P Series (pinch wheel) feeds are used when materials aren’t sensitive to pinching pressure and in operations where minimal pulling force is necessary. They’re available with roller widths from 2 in (50 mm) to 5.5 in (127 mm) with roll materials offering different traction and wear characteristics. Pinch roll pullers are ideal for manufacturing band saw blades, weed whacker line, 3D printer filament, moving and punching rigid profiles, and for capturing materials trimmed from the edges of various profile and film extrusions.

C Series (caterpillar) feeds provide uniform pressure over the entire traction length, which enables greater pulling force without product deformation. Belt configurations range from 2 in (50 mm) wide by 9 in (230 mm) long to 4 in (100 mm) wide by 18 in (460 mm) long. Caterpillar pullers are ideal for pulling materials through braiding machines, feeding disc brake materials into grinders, pulling wire and cable, and pulling extruded vinyl siding.

Belt and pinch wheel materials include sponge, gum rubber, silicone, neoprene, urethane, and nitrile; some are approved by the U.S. Food and Drug Administration. Various durometer ratings are available to suit application requirements. Additional options include left-to-right configuration and OSHA guarding package.
