Bertsch Hydraulic Angle Rolls

Machine Design

The Bertsch Double Pinch design reduces end flats to a minimum. The top roll is in a fixed position, while the two lower rolls have independent hydraulic adjustments. This design provides ease of operator control as well as more uniform rolling results.

Vertical or Horizontal Working Position

The Bertsch Angle Roll can be designed to work equally well in the vertical or horizontal position.

Hydraulic Drive

All three rolls are driven by planetary speed reducers for positive feed and efficient torque transmission. Bertsch Angle Rolls are designed with a self speed compensating drive for proper roll rotation between the top and lower rolls.

Hydraulically Adjustable Guide Rollers

The hardened guide rollers are hydraulically adjustable from the operator’s control pendant. Each guide roll assembly is provided with a “leg-in” attachment.

Operator’s Control Pendant

All essential operator functions are located in a “walk-around” pendant type control for maximum mobility.

Standard Dies Furnished

One complete set of standard dies is furnished with each machine. Each die set is supplied with one hardened spacer to provide support for the tip of the vertical leg being formed. Standard dies will accept: flat bar, bar-on-edge, square bar, angle leg-in, angle leg-out, “T” leg-in, “T” leg-out, and “T” on web.
