Abstract: An apparatus arranged for grinding, polishing, etc. with a closed loop 5 of grinding, polishing, etc. belt mounted on the output shaft of a motor 1 and driven by a rotating drive wheel 4. This loop belt 5 is intended to be applied against a workpiece which is to be machined by means of the loop belt 5, said closed loop 5 having loop portions differing from one another in a running direction. The loop 5 is steered by steering members 2:8, 9:10, 11 to adopt an essential L-shape and comprising at least two loop portions, of which the loop portion 5d which is arranged to make contact with said workpiece is preferably selected shorter than the other loop portion 5a, 5b, 5f, 5g.Said drive wheel 4 for driving of the belt 5 is arranged displaceable relative to a foundation 17 by a guide 19 steered by the foundation 17 and turnable by means of guide members 3 arranged on the guide. An angle .phi.

Abstract: The disclosure relates to an apparatus for the controlled infeed, storage and discharge of elongate objects (20, 21, 22, etc.). The apparatus essentially includes a rotary drum (1) and at least one strap, belt or the like (2, 3, 4). The invention, the strap, belt or the like (2, 3, 4) is connected to the rotary drum (1) which is disposed to rotate in two different directions for winding up and unwinding of the belt (2, 3, 4) or the like. The elongate objects (20, 21, 22, etc.) are aligned with the drum (1), are disposed on the belt (2, 3, 4) or the like, and are arranged to be held by the belt (2, 3, 4) or the like against the rotary drum (1). The belt (2, 3, 4) or the like and/or the elongate objects (20, 21, 22, etc.) are moreover disposed to be prevented from movement in their storage position by a holding device (6).
