Three-Roll Plate Bending Rolls

LEMAS initial pinch bending rolls feature hydraulic adjustment of the rear bending roll and the lower pinch roll. In addition, the rear roll is hydraulically tiltable for cone rolling, and the hydraulic drop end makes it simple to remove the completed cylinder from the rolls.

Unique to LEMAS initial pinch machines is the Quick and Easy pinch gauge adjustment. Consistent positioning of the lower pinch roll is critical to rolling consistent quality cylinders. By simply inserting a small tab of the material thickness to be rolled into the pinch gauge control, the lower pinch roll is properly positioned to ensure that consistency.

Sumitomo Cyclo® 6000 gearless speed reducers, featuring unique epicycloidal design, have advantages superior to speed reducers using common tooth gears. Unlike gear teeth with limited contact points, a Cyclo has two-thirds of its reduction components in contact at all times. This design enables Cyclo speed reducers and gear motors to withstand shock loads exceeding 500% of their ratings, and provide exceptional performance, reliability and long life in the most severe applications.

Other standard features include Direct-Drive Design using no belts, cone rolling attachment, rolls heat treated to 50Rc, digital readout for positioning the rear bending roll, and grooves for 1/4″, 3/8″ and 1/2″ round bar (except 80 series models).

The long list of standard features together with competitive pricing makes the LEMAS roll a continuing favorite of the metal fabricating industry.
