Three Models for Uncured Rubber Sheet or Slabs from 28" to 42" (700 to 1100 mm) Wide

Eliminate costly secondary cutting operations for milled and calendered uncured rubber sheet or slab stock
Cut uniform slabs, rectangular transfer pads or compression mold loads continuously at the end of your batch-off system
Synchronize the Rotary Shear Cutter in-feed conveyor to your batch-off unit to simplify your set-up and operation
Reduce your maintenance headaches with a rugged machine built to last

Whether you are a custom mixer or mixing rubber in-house, the reliable production of uniform width slit strips of uncured rubber for cold feed extruders and injection molding machine feed is a problem. If the strips are cut at the batch-off mill, you have to fight dropped or mangled strips in your batch-off system. Most home made slitters are not rugged enough to cleanly slit all types of stock following the batch-off.

Pallets or cartons of wig-wagged sheet can be fed cold into an off-line version of the Rotary Slitter to produce slit strips from custom mixed rubber sheet. The sheet must be capable of readily unfolding from the pallet or carton without sticking or jamming.

The GOODMAN Rotary Slitter is a very simple, but ruggedly built, machine designed to cleanly slit cold uncured rubber sheet or slabs into uniform width strips. Whether your products are 40 Durometer or 90 Durometer, you will still get cleanly cut strips every time. Features of the GOODMAN Rotary Slitter include the following:

Heavy welded steel frame
Heavy duty alloy steel blade arbor turning in spherical roller bearings
90 Durometer polyurethane covered anvil roll turning in spherical roller bearings
10" (250 mm) diameter hardened toolsteel slitting blades with PETE coating
Large diameter spacers between blades to keep the arbor rigid
Stripper/hugger belt assembly to guide slit strips out from between slitting blades
Infeed and discharge conveyors integral with machine
AC gear motor for off-line applications and either AC variable frequency or DC drive for in-line applications; can be configured to follow reference signal or loop control system
In-line systems can operate at up to 120 FPM (36 MPM)
Custom machine configurations welcomed, including longer infeed and/or discharge conveyor, operating height, maximum product width
