Bending machine for bending Biegeboy upturned droves to bending height 50 mm. Smallest radii are produced in multiple passes. By Biegeboy aufgekantete hordes bent. The maximum bending height is 50 mm. By a special pressure roller system the material is stretched. Depending on the radius multiple passes are required. By the roller system, the material processed gently and evenly and can also be used for color-coated materials. There are two different applications: When working in the stator are supplied to the upturned droves unit by hand and drawn reciprocally, possibly in multiple passes. For long droves is advisable to use at the site. The bands are attached to a point on the substructure and the upstand at the Biegeboy guided along. The use of two units can be stretched in a single pass, it is with the use of a device working alternately. The drive unit has its advantages and return, the operating speed is adjustable.
