DEVICE FOR APPLICATION OF COATING ONTO ROLL MATERIAL Russian patent published in 1998 - IPC

FIELD: equipment for production of flexible roll materials with one-or two-sided coating, applicable in mechanical rubber industry, as well as in production of artificial leathers, in paper industry, etc. SUBSTANCE: the compound application mechanism is made as applying-sizing roll 6 with spreading knife 7 and an appliance adjusting its gap relative to the roll that is installed in fixed axle 9 with disks 11 inside it. Infra-red sources 12 and 13 are fastened on disks 11 from the inner surface of the roll. Fixed axle 9 carries also roller 18 on levers 17, which is turned by a drive around the sizing roll changing the angle of roll coverage by material at turning. The deflection assembly has roller 23 located at the ends sizing roll 21 at the instant of its engagement with applying-sizing roll 6. For application of coating onto the other side of material the frame additionally carries mechanisms and assemblies similar to the respective mechanisms and assemblies for application of coating onto the first side. The additional mechanisms are separated from the main ones coating before the second application. EFFECT: enhanced efficiency. 4 cl, 7 dwg
