Abstract

626,728. Coating webs. DEXTER, L. N. Nov. 30, 1946, No. 35547. Convention date, Nov. 30, 1945. [Class 140] A striped coating is applied to a fabric 11, Fig. 1, by drawing it under a trough 18 disposed transversely of the fabric and divided into a series of open-bottomed cells for differently coloured compositions by partitions 31, Fig. 4, extending between the front and rear walls 28 and 27 of the trough. The lower edges of thepartitions 31 are tapered to a sharp edge 36 at their forward or exit ends adjacent to the front wall 28. The front wall may also have a sharp lower edge 33. The fabric is pressed against the bottom of the trough 18 by a tensioned fabric band 37, Fig. 1, which may consist of two layers of canvas enclosing a resilient pad of sponge rubber. The cells may be supplied with coloured coating composition from overhead tanks 20 through pipes 19 with handoperated valves 21 and, if desired, also floatcontrolled valves to keep a constant level in the cells. Some cells may be supplied from a feed trough 44, Fig. 4, provided on the front of trough 18, the paint flowing through holes 45 in the front wall 28. The fabric 11 on its way to the trough from a fabric reservoir 10 passes around roller 12, through an aligning mechanism 13, over rollers 14, 15, a brush 16 and a roller 17. The coated fabric is dried in an oven 23 and wound into a roll 26.
