Abstract

941,073. Treating fibrous webs. PORTALS Ltd., and A. J. TOOTH. Feb. 9,1962 [Nov. 21, 1960], No. 39992/60. Heading D1L. Impregnating liquid (e.g. emulsions of polyvinylacetates or of polybutadiene styrene copolymers, on solutions of sodium carboxy methyl cellulose) is applied to a fibrous web 11 by firstly applying the liquid to a travelling web-supporting band 12 (e.g. of wire mesh) and then bringing the web into close contact with the band. In Fig. 1, the band 12, driven by roller 14 at a speed equal to or slightly in excess of the speed of the web 11, has the liquid applied thereto by a transfer roller 15 driven at a surface speed equal to that of belt 12 which it contacts or closely approximates (0 to 0.030 inches). The liquid is, in turn, applied to the transfer roller by means 16 which may, as shown in Fig. 2a take the form of an applicator roller 30 contacting the transfer roller and dipping into a bath 31 of the liquid (which may be heated electrically at 32 for ease of application). In another form, further rollers may be inserted between applicator roller 30 and transfer roller 15. In a further form, transfer roller 15 dips directly into the liquid bath and an air doctor is provided to remove excess liquid therefrom. In Figs. 1 & 2a smoothing rollers 17, 33 are provided and may be driven at a surface speed considerably greater than that of their associated roller while roller 33 may additionally be caused to oscillate parallel to the axis of roller 30. Adjustable doctors 34 limit the width of the liquid layer on roller 34 to be equal to the width of the web 11. Rollers 19 are spring urged towards belt 12 in an adjustable manner to press web 11 thereagainst. In Fig. 3 the supporting band 45 runs through the liquid in tank 48, the excess liquid being removed by an air doctor 48 (having adjustable slot plates 49) and by a pair of resiliently covered (e. g. rubber) rollers 50 pressed against the band in an adjustable manner. The band 12 or 45 may be of wire mesh, perforated stainless steel, perforated films of polyvinyl chloride or polyethylene or it may be of natural or synthetic fibres or paper in similar porous material coated with an inert, non-stick substance such polytetrafluorethylene or silicone compounds.
