Bertsch B-Series Bending Rolls

American made since 1879, Bertsch Bending Rolls utilize industry-leading hydraulics and electrics in both Three-Roll Initial Pinch and Four-Roll Double Pinch robust designs. Bertsch Bending Rolls are supported by an experienced and knowledgeable applications & technical service team based in Rockford, IL.



Three-Roll Initial Pinch

Ability to pre-bend material to minimize flat
Able to bump form easily
Requires less floor space than three roll double pinch (both ends of the plate are preformed from the same side of the machine)
Able to square plate prior to rolling
Machine can be easily fitted with feed tables, material supports, or set in a pit
Material remains square throughout the entire rolling process once it is squared and pinched between the pinching rolls
May require operator to remove plate from machine and rotate 180 degrees to pre-bend trailing edge of plate if the part requires pre-bending on both ends



Four-Roll Double Pinch

Easiest machine to operate since material is clamped during the squaring process and held during the entire rolling process
Able to pre-bend, roll and post-bend the entire piece without releasing the pinch, allowing some parts to be pre-bent and the entire cylinder rolled in a single pass
Because the plate is clamped through the entire bending cycle, a rotary encoder can be utilized to indicate how much plate has been fed through the machine, allowing it to be fitted with an optional CNC control
Material is fed into the machine parallel to the floor, easily fitted with feed tables and side supports, or placed into a pit for ease of operation
Less floor space is required because the part is rolled up and over right after the first pre-bend
Machine can be fed from either direction
