A process for preparing plates (22,32) for cylinders (20,30) to treat items of the paper processing industry (40) is described, the process comprising the following steps: acquisition of a treating pattern (50) to be produced on the item of the paper processing industry (40); creation of a 3D reference model of the treating profile elements (25, 35) according to the treating pattern (50); application of the treating profile elements (25,35) on the plate (22,32) by means of an additive manufacturing process of polymeric material, preferably thermoplastic polymeric material, in accordance with the 3D reference model of the treating profile elements (25, 35), carried out by means of at least one printing nozzle (80) of said polymeric material. A device (250) for preparing plates (22,32) is also described, in addition to a plate (22,32) to treat items of the paper processing industry comprising at least one treating profile element (25,35) of polymeric material, preferably thermoplastic polymeric material, deposited on said plate by means of an additive
A process for preparing plates (22,32) for cylinders (20,30) to treat items of the paper processing industry (40), the process comprising the following steps:
The process according to any one of the preceding claims, wherein in said application step of the treating profile elements (25,35) on the plate (22,32) by means of an additive manufacturing process of polymeric material, said plate (22, 32) is positioned on a supporting plane (90) or a cylindrical support (91).
The process according to any one of the preceding claims, wherein said polymeric material printed by said nozzle (80) is PTEG and/or said at least one plate (22, 32) is made of polymeric material, preferably PVC.
The process according to any one of the preceding claims, wherein the nozzle (80) is movable along at least one axis (X), preferably along at least two axes (X, Y) perpendicular to each other.
The process according to any one of the claims from 4 to 7, wherein the supporting plane (90) or the cylindrical support (91) moves at least along a vertical axis (Z).
The process according to one of the claims from 4 to 8, wherein said cylindrical support (91) is rotatable around its own rotation axis.
The process according to one of the preceding claims, wherein the application of the treating profile elements (25,35) on the plate (22,32) by means of an additive manufacturing process comprises the formation of a plurality of stacked layers (70).
The process according to any one of the preceding claims, wherein a step of displaying and/or modification of the deposition parameters of the treating profile elements (25,35) is provided, said deposition parameters of the treating profile elements (25,35) preferably comprising at least the height (h) of the nozzle (80) relative to the deposition surface, the displacement speed of the nozzle (80) relative to the deposition surface, the delivery speed of the material, or any combination of the preceding parameters.
A device (250) for preparing plates (22,32) for cylinders (20,30) to treat items of the paper processing industry (40), preferably according to the process according to any one of the preceding claims, the device comprising at least one nozzle (80) for the deposition of polymeric material, preferably thermoplastic polymeric material, on at least one plate (22, 32) by means of an additive manufacturing process for the production of treating profile elements (25, 35) according to a 3D model of the treating profile elements (25, 35).
A plate (22,32) to treat items of the paper processing industry comprising at least one treating profile element (25,35) of polymeric material, preferably thermoplastic polymeric material, deposited on said plate by means of an additive manufacturing process of polymeric material, preferably by means of a process according to any one of the claims from 1 to 13.
