ProStar™ Double-Pinch Angle Rolls

30 Preconfigured Models

Praxair’s ProStar™ fully-hydraulic, double-pinch angle rolls come with an impressive set of standard production features. All machines ship with a standard, universal roll set to roll most all common shapes.


General Characteristics

The PRSPAR Series features independent hydraulic adjustment of lateral bending rolls, with powered rotation of all three bending rolls. Medium-sized models are designed to operate shafts with both horizontal and vertical orientations. These versatile units are ideal for rolling standard and special sections, tube and pipe in mild and structural stainless steels, aluminum, brass, copper and other materials.


Available Options 

  • Rolls for tubes, pipes and special profiles
  • Tooling for production of half-tubes
  • Overhead supports for coil production
  • Compression and tension tooling for C, H & I beams, hard way
  • 3 CNC control options with automation levels for repetitive jobs and production of variable-radius, multiple-radius bends
  • Powered movements on lateral material guides on smallest models
  • LED digital displays for lateral guides or CNC controlled guide movements

Surface and pit mount models for section sizes up to:

  • Flats hard way 20 in.
  • Schedule 40 pipe 20 in.
  • Angle leg-out & leg-in 10 in.
  • Square tube 20 in.
