Abstract
An apparatus includes: a receiving surface configured to receive a stack of grinding discs; a frame arranged substantially parallel to the receiving surface so that the stack of grinding discs is positioned between the receiving surface and the frame, the frame only partially overlapping an outer rim of a topmost grinding disc of the stack of grinding discs; and a mechanical pretensioning unit coupled with the frame such that a defined force is exerted by the frame on the stack of grinding discs.
Claims15
An apparatus, comprising:
- a stationary receiving surface configured to receive a stack of grinding discs;
- a frame movably mounted on the stationary receiving surface and including a ring that is arranged substantially parallel to the stationary receiving surface so that the stack of grinding discs is positioned between the stationary receiving surface and the ring, the ring only partially overlapping an outer rim of a topmost grinding disc of the stack of grinding discs;
- and
- a mechanical pretensioning unit comprising a weight mechanically connected to the frame below the stationary receiving surface, such that the stationary receiving surface is vertically interposed between the weight and the ring and a weight force of the weight is transferred to the ring and the ring is pulled towards the stack of grinding discs and the stationary receiving surface.
