Abstract

632,074. Coating webs ; coated paper. COPEMAN LABORATORIES CO., and JENNINGS, H. Y. Aug. 18, 1941, No. 10466. [Class 140] An aqueous dispersion 13 comprising natural and/or synthetic rubber is applied as a coating to a moving sheet of material 10, e.g. paper by a roller 11 which dips in the dispersion and rotates in a direction opposite to that in which the sheet moves. If desired the roller may rotate at a higher speed than the speed of movement of the sheet material. After application of the coating the sheet material may be dried and the coating partially cured by passing the sheet material adjacent a heating element 16, over a heated drum 17 with coated surface exposed, and the sheet then wound on roll 20 with coated side innermost after passing under guide rolls 18 and 19. The direction of travel of the coated sheet material prior to the drying step may after leaving the coating roller be changed abruptly, for example, as shown through a right-angle. The coating, if desired, may be stripped from the sheet material. The products are suitable for use as wrapping materials. Specification 632,141 is referred to.
