[Classes 100 (i) and 100 (ii).] Printing processes; printing and embossing surfaces; cutting and winding webs.-A method of producing simultaneously a number of copies of a sound record or other original in the form of a long strip, consists in producing on a continuous cylindrical surface a copy of the original in the form of a helix and rotating the cylinder in contact with a strip of material so that multiple copies are produced on the strip simultaneously from the adjacent convolutions of the helix. The copies may be produced by ink printing, photographic printing, or by embossing. In one form suitable for reproduction by ink printing, a drum 1, Fig. 1, is provided with a photomechanical printing surface having the design in the form of a helix, by one of the methods described in Specification 331,278, [Class 98 (ii), Photographic processes &c.], and by means of this drum and an impression roller 2, a strip B of paper or other material is printed with a number of side-by-side copies 3. The strip B is then passed between a pair of cutting rollers having helical cutters to divide the strip into separate bands which are wound into spools by means of driven rollers 6, 7, 8, Fig. 6, which are set at an angle to each other so that the spools 10 automatically travel along the space between the rollers as their diameter increases. For reproduction by photography, the drum 1 is made transparent with opaque helical markings and is illuminated from within, the strip B in this case being sensitive to light. For the reproduction of sound records adapted to work in conjunction with a stylus, the strip B is formed of thermoplastic material and the drum is prepared by recording the sounds directly on its surface or from a strip record in any suitable way.

Filed: 1942-05-13
Abstract: 557,369. Laminated fabrics. BELL, A. S., and GREENWOOD, E. L. May 13, 1942, No. 6484. [Class 140] A two or more ply laminated fabric comprises plies of textile material bonded together at intervals by means of thermoplastic material, each of the separate plies having structural elasticity in the line of bondings, e.g. by being formed of knitted fabric or woven fabric containing crepe twisted yarns so that the laminated fabric is elastic in that direction. In one example comprising an inner ply united to two outer plies the interlining fabric is a knitted material formed of bands 14 of cotton alone alternating with bands 13 containing cellulose acetate which is plasticized by immersion in a solution of a plasticizer, the plasticized interlining being then sandwiched between two plies of all cellulose acetate knitted fabric and the three plies united by heat and pressure resulting in a laminated fabric wherein bands 15 in which the cellulose acetate yarns of the interlining have coalesced with the cellulose acetate yarns of the outer plies alternate with bands 16 in which the cotton courses 16a are sandwiched between but not united to the two layers 17, 18 of cellulose acetate. A sweat band for hats may be cut from the material in a direction perpendicular to the alternating bands and other articles which can be made having elasticity in one direction are chainstraps for hats and helmets, belts, components for braces, garters and military body-harness including head-harness of respirators. The interlining may contain thermoplastic fibres throughout and may be rendered adhesive in bands by application of a plasticizer or solvent and the outer plies may be of non-thermoplastic material, e.g. cotton, linen, silk, wool, artificial proteinaceous fibres or fibres of condensation polymers of diamines with dicarboxylic acids. e.g. polyhexamethylene adipamide and like fibre-forming polymers. Instead of using cellulose acetate as the thermoplastic material of the interlining other thermoplastic materials may be employed such as other cellulose esters, cellulose ethers and polyvinyl compounds.
