Patent ID: RE45067

Claim:
A numerical jet machine for viscous material product for the application of a coating to a plastic face of a substrate, including: a reservoir configured for including a viscous product having viscosity between 100 and 1000 centipoises, an input magazine and an output magazine, work stations and a computer device to manage the operations on each of the work stations, a movement device for moving the substrate between the different work stations, a device for grasping and transferring the substrate from the input magazine to the movement device and from the movement device to the output magazine, further comprising at least said work stations comprising at least : a read station for reading and determining at least one position of the substrate and/or of markers placed on the substrate, a an application station including a series of plural nozzles arranged in a ramp, each of the nozzles including a hollow needle, a piezoelectric actuator affixed to a resonator formed by an assembly included in each hollow needle, a drying station with an infra-red or heated air current of UV drying oven; , wherein each hollow needle is piloted separately by a command the computer device, and is arranged to be fed from said reservoir configured for including said viscous product to be applied onto the substrate during relative movement between the substrate and the application station, to apply the product in a given zone on the substrate, wherein each hollow needle is arranged to be vibrated by its associated piezoelectric actuator, with the excitation of the actuator, in duration and power, determining the dimensions and the shape of the drop of viscous product, to apply the product in a given application zone on the substrate, said application zone being defined for each substrate by a configuration file concerning the zone shape, the zone position on the substrate in relation to the position determined by the read station, the quantity of product to be applied, wherein of the management computer device is arranged to be responsive to an established programming said configuration file for controlling the command device of the application station according to the position translate the information into parameters of relative movement of the substrate, to the read station and to the drying station with the management of the nozzles, and selective control of the information received at the different work stations to coordinate the operations each actuator of each nozzle .
