Contact detail and maps
During the rolling process, the material is rolled forward and backward between three rollers. By adjusting the distance between the centre roller and the two side rollers, the radius/diameter is changed.

After each roll, the material is measured. If it is not on size, the distance between the rollers is adjusted and the material is rolled again. This is repeated, until the material is on size.

For each profile a set of three tools is needed with the negative form of the profile to minimize distortion. All material gets distorted in the rolling process. The thicker the material, the less distortion.

For a large radius, a thinner wall is sufficient. The smaller the radius, the thicker the wall of the material to minimise deformation.

Every rolling machine needs extra material. On each end of the material, there is a straight piece and an indentation. The length of the straight piece depends of the distance between the centre and the side roller of each machine.

Business hours are from Monday to Thursday 08h00 to 16h50. Friday 08h00 to14h00. No loading or off loading after 16h15 and on Fridays 13h15 without prior arrangement. (If you need to load or offload material, please come early, so that my employees can catch their train. If they miss the 17h20 train, some of them will arrive home after 22h00.)
