Anti-twist system for guillotine shears

During the cutting process, internal stresses tend to twist the material. Especially when width is reduced with respect to thickness, the strip will tend to curl.

Anti-twist system contrasts the piece warping by pushing it against the upper blade.

The unique Anti-Twist system of Gasparini guillotine shears consists of a series of hydraulic cylinders placed below the lower blade, which support the sheet metal against the upper blade.

The cylinders exert a counter-pressure in proportion to the thickness, thus compensating the twist effect of the sheet.

This opposing action allows us to prevent the twisting effects, which depend on the geometry and the characteristics of the material and the cutting parameters.

The Continuous Anti-twist version distributes the force more evenly. It serves to reduce the possibility of damage to the surface of thin metal sheets, or in case of delicate finishes such as polished stainless steel or pre-painted plates.
