SweBend Four-Roll Plate Bending Rolls

Time efficient and resource-saving…
The PB4 series stands for fast and efficient production. We have designed our plate bending machines according to the double pinch pre-bending principle.

This technology provides you with three benefits:

• Minimal residual flat ends

• Minimized quantity of processing steps

• Up to three times faster production

Our highly configurable machines and accessories offer you maximum flexibility. A plate bending machine matched precisely to your specific production requirements contributes considerably towards maximizing your real world productivity. It is therefore one of our guiding principles to find the best possible solution in partnership with you, the end user.  We do not just produce and sell “off the shelf” standardized machines. Instead, we start each new project with a detailed consultation. This is how we, together with you, find the best bending solution for your task. We have tailor made solutions for even the most complicated production tasks.

The SweBend Four-Roll…
With our four-roll double-pinch PB4 machines, plates can be bent on both sides without having to turn the plate. This results in only minimum residual flat ends of 1.5- to 2-times the plate thickness. As there is no need for additional processing steps for bending the ends, production time is also up to three times faster

Touchscreen CNC control…
For simple operation, the 4-roll machines can be optionally fitted with the newly developed, highly intuitive “Seven” CNC control. This advanced operating environment simplifies all rolling operations from the most basic simple cylinders to highly complex shapes such as ellipses and even specialized products with variable radii.  Now these traditionally difficult shapes can be produced quickly and effortlessly.  Equipped with a large, easy to use touch screen interface the “Seven” CNC control  will make setup fast and easy and thereby ultimately reduce production times.  The control is also network-compatible to make off-line programming and remote diagnostics a simple and easy process.
