Abstract: The disclosure relates to a cutting blade that is rotatably drivable and provided for machines for slicing food products, in particular high-speed slicers. With the aid of a mounting area surrounding a rotary shaft, the cutting blade is fixed to a drive shaft of the machine. A distance area is provided outside the mounting area but inside the cutting edge area. The disclosure aims at improving the cutting blade with respect to its stability and configuring it such that it has the lowest possible weight. For this purpose, alternately recessed and raised formations are provided in the distance area.

Abstract: The invention relates to a mechanism for laterally aligning sheets, said mechanism comprising a suction device that grips the sheets and guides them with the side edges against a side lay. The mechanism comprises at least one suction plate provided with suction holes. The invention modifies a mechanism for laterally aligning sheets in such a way that heavy and special print substrates can be gripped and aligned easily by the side edges. The mechanism of the present invention comprises suction openings (8.1) of the suction holes (8) open into grooves (9), which are open towards the sheets to be aligned (FIG. 1).
