  • Patent number: 5393218
    Abstract: Dough (10) should, in a volumetric sense, be measured in dough pieces, which during extended use, must very precisely take place. The improved measuring device can be built in dough dividers and gives, through the specific piston construction (3) with connected parts, an amazing result. In the sidewall of the piston an annular-shaped recess (20) is provided and in which a filter (21) is fitted. To the recess (20) a crosswise channel system (15) with a bore (16) is fitted, which is connected to a flexible suction/press hose (17).

  • Patent number: 4686875
    Abstract: An apparatus for cutting bread products into slices, consisting principally of: a stand (1); a supporting surface (3) for the product to be sliced, carried by the stand (1); two groups of parallel cutting blades, each group being driven with an oscillating motion transverse to the supporting surface (3), the blades of the two respective groups (5', 5") being mounted alternately next to one another; and a pressure organ (6) which can be moved over the supporting surface (3) towards and away from the groups of blades (5), wherein the cutter blades of one group (5') include a different angle with the supporting surface (3) than the blades of the other group (5"), so that during cutting the blades of one group are ahead of the blades of the other, whereas an arrangement of this kind also has the advantage that the bread can deflect more easily, so that resistance is reduced and the cutting time is consequently shortened to approximately 3 seconds.
