Claim 0:
1. A blade for machines for cutting elastic products into slices, the blade comprising:
a plate-shaped base body having a rotation axis, a rear cutting surface, which forms a part of a blade rear side of the plate-shaped base body, and a front cutting surface, which forms a part of a blade front side, wherein the rear cutting surface and the front cutting surface meet in a continuous cutting edge, wherein
the blade rear side extends axially outwards from a cutting plane, defined by the cutting edge on a front side of the plate-shaped base body,
the rear cutting surface is inclined relative to the cutting plane at a cutting angle,
the rear cutting surface is positioned adjacent to a pressing surface, wherein a portion of the pressing surface extends on the blade rear side at a pressing angle relative to the cutting plane which is smaller than the cutting angle,
at least one recess is formed only in the pressing surface on the blade rear side, with a radially outer end of the at least one recess terminating distant from the cutting edge, and a radially inner end of the at least one recess terminating radially outward from a radially inner end of the pressing surface,
wherein a size and/or a shape of a cross-sectional surface of the at least one recess transverse to the cutting plane varies in a direction in which the cutting edge extends, wherein a position of the at least one recess relative to the cutting edge varies in the direction in which the cutting edge extends, and
the at least one recess extends only along a part of a length of the cutting edge, or the cutting edge is a finite cutting edge and the at least one recess ends at a distance before a beginning and/or before an end of the cutting edge.
