METHOD AND DEVICE FOR APPLICATION OF MATERIAL TO CLOTH Russian patent published in 2003 - IPC

FIELD: methods and devices for manufacture of cloth with strips applied from additional material. SUBSTANCE: device includes the first appliance for formation of steel of main material from the first suspension and for motion of made sheet along the first path; the second appliance for preparation of the second suspension; applicator with moving hole for repeated discharge of the second suspension after motion of main material sheet. Applicator with moving hole includes chamber box for installation of tank with the second suspension across the first path; endless conveyor with hole receiver through chamber box; driving member operating on endless conveyor for continuous motion of hole along endless path and periodically through chamber box, system of flow distribution for introduction of the second suspension into chamber box along chamber box spaced from each other locations; systems of flow regulation for taking readings of fluid medium pressure in said locations; and controller for determination of supply passage which is adjacent to definite zone of the maximum variation of pressure. Said controller also controls output of the remaining zones of supply as opposed to control of output in definite zone of supply. Technical result of the invention consists in provision of homogeneous application, possible correction of heterogeneities in state of fluid medium, smoothening of adverse effect of conveyor on fluid medium, provision of removal of any excessive material in the form of suspension and minimization of destructive effect of applicator edge sections. EFFECT: higher efficiency. 51 cl, 15 dwg
