ABSTRACT:
To sand the surface of an item (3) uniformly smooth, a sanding machine is used with sanding tools in the form of sanding rollers (29) which are rotated as well as turned in the same plane, and which at the same time are also moved in a different direction from the direction in which the item is conveyed, whereby during the working stroke the sanding elements on the sanding rollers (29) will sand at all possible contact angles in relation to the item (3).
To move the sanding rollers (29), the apparatus comprises a motor-driven crank arm (7), in sliding engagement with a carriage supports the sanding rollers (29), and drives the carriage on rails (33) which extend in a circle about the machine (1). This achieves a stable and robust construction which also gives the sanding rollers (29) an expedient movement characteristic, which compensates for the predominantly longitudinal sanding movements to which the items are exposed in the outer areas.
