Description

[Technical field to which the invention relates] R. 27(1) (A)



[0001] The bladed multishearing machine represents an important technological innovation in the mechanical field which is applied to the industrial production in different fields (alimentary field: meat, fish and so on; wood; resin).

[Background art] R. 27(1) (B)



[0002] The present system are based on rotaring disks, interposed each other with rings to measure the cut thickness.
These systems produce excessive waste in that the cut disk is 2,5 mm and the same thickness will be lost from the product to be dissect.
The consequences are negative either on the economic side or on qualitative results in that the product appears the formed and crumbled.

[Technical problem to be solved, disclosure and advantageous effects of the invention] R. 27(1) (C)



[0003] The bladed multi-shearing machine, as proposed in the enclosed mechanical drawings, is able to carry out a piece of work in a careful and safe way. The cut thickness can be changed in few minutes and the speed of work is beyond comparison with other systems in that the blades produce less friction.

[0004] The performance of this machine is of an elevated quality of the final product, an exiguous waste, elevated economics of scale in terms of production cost and an increase of the productive potentiality intended as relation between production/time (in minutes).
This machine is useful where a cut of different thickness is necessary (meat, fish, tuna-fish and cooked and raw aliments) and it guarantees a greater productivity and above all precautionary measures for the staff.
It is made of suitable materials used in the alimentary field and it is equipped with the best electronics systems for its working and for the security of the staff.
This machine, using the suitable materials, but with the same working, can be used in other fields tor example in the wood and resin processing. The machine permits, so equipped, the cut of the product in five pieces of equal size with a thickness from 1 cm to 16 cm or it can cut five different pieces varing the entries. The firm can increase or reduce the thickness of the cut.

[Description of at least one way of carrying out the invention by reference to the drawings] R. 27(1) (D) and (E)
