    Custom surface cutting machine for bread dough pieces or similar
    OBJECT OF THE INVENTION
    The purpose of this application is the registration of a machine for custom surface cutting of pieces of bread dough or similar.
    More specifically, the invention proposes the development of a customized surface cutting machine for pieces of bread dough or the like that allows a custom and repetitive cut of a cutting design with complex shapes, on the piece of bread dough in a process continuous production, being the cut made by means of pressurized water.
    BACKGROUND OF THE INVENTION
    It is known to make cuts distributed in parallel to each other on the surface of a piece (or bar) made from a bread dough, whose cuts are made prior to baking the bread dough. The cuts have a decorative purpose that allows you to customize the piece of bread as well as functional by allowing the bread to have no defects in shape due to the effect of cooking and improve the baking of the dough.
    These cuts are made manually on the surface of the bread dough by an operator using a cutting edge tool. However, this process has a series of drawbacks, among which are the fact that a repeatability of the shape or depth of the cuts made during a production process cannot be guaranteed. In addition, since the cutting is done manually, there is a risk that some piece of bread dough does not have the cuts or even the same number of cuts due to an oversight of the operator in charge of making the cuts.
    It is known in the state of the art the Spanish patent ES 465371 which describes a
    installation for the manufacture of bread that comprises scarification means
    Automatic bread based on the use of a series of cutting blades supported on a

    support structure and located on a conveyor belt. Although this installation allows to perform some repetitiveness in the cuts made, it does not allow in any case to customize the type of cut to be made, so its versatility is limited. In addition, in the case of modifying the cut to be made on the bread, it would imply the disassembly of the structure where the blades are for replacement, a fact that would entail a considerable non-operative time as well as the provision of a different number of structures or provision of cutting blades Another drawback is the fact that the cutting blades must be replaced due to their wear.
    In addition, the applicant is not currently aware of an invention that has all the features described herein.
