The Spiral Machine CAL35 Evo is a complete version of Calendering Unit studied to calender rods (circles, spirals and centrings) with Ø from 10mm to 32mm (from 0,39 in to 1,26 in).
The spiral machine CAL35 can execute circles with practically boundless bending radius (bars for roof supports) and spirals with adjustable diameter from min. 28 cm to over 200 cm. Rollers are made in heat-treated alloy steel.
The standard machine is designed to work in vertical, as shown in the side picture, but – upon request and subject to estimation – it can be predispose to the horizontal development.
The double-speed motor (8 rpm and 16 rpm), selectable by the electrical panel of the spiral machine, makes it possible to work small diameters very quickly (choosing the maximum speed) and calender larger diameters in total safety (using the reduced speed).

The working top is constituted by three rollers, placed in triangular position, all of them in a special heat treated alloy. The two largest ones, named “towing rollers”, are provided with manifold inclined slots, with the function to catch the bar; the central roller, called “idle roller” and adaptable through the specific screw, has the role to determine the curving radius.
Depending on the requirements, the Spiral Machine CAL35 Evo can be prepared to work in horizontal or vertical position.
