<p>A blade assembly for a meat cutter, which assembly includes a drive shaft having an axis, a plurality of driving discs made of light metal mounted on the drive shaft, a plurality of cutting blades alternating with the driving discs along the shaft to form a stack with the driving discs, two end pieces mounted on the shaft and each disposed at a respective end of the stack, the driving discs being connected in a form locking manner with the shaft and the blades being axially clamped between the driving discs in a force transmitting manner, a plurality of outer rings of chemically resistant plastic material each disposed around a respective one of the driving discs and end pieces, and being substantially coextensive, parallel to the shaft axis, with the associated driving disc or end piece, and each ring having a radial dimension substantially equal to the axial dimension of each driving disc, and a plurality of sealing rings of a chemically resistant plastic elastomeric material each pressed into a respective outer ring via an associated axial end face of the outer ring such that each sealing ring protrudes for a distance into the respective outer ring via the associated end face, with each outer ring which is disposed around a driving disc having a sealing ring at each end face and each outer ring which is disposed around an end piece having a sealing ring at that end face which faces inwardly of the stack.</p> |
