Abstract

881,821. Moulding corrugated plastic materials. GADANI, C., and GADANI, U., [trading as C-I-M.E.M. DEI F. LLI GADANI]. April 14, 1960 [April 14, 1959], No. 13457/60. Class 87(2). A press for the production of longitudinally corrugated plastic sheets comprises series of rollers 1,1<SP>1</SP>, 2,2<SP>1</SP>, 3,3<SP>1</SP>, 4,4<SP>1</SP>, and 5,5<SP>1</SP> each series having upper and lower rollers which alternately partly intervene and the transverse spacing of adjacent rollers decreasing to the series furthest from the material supply station and co-operating mould parts 9,9<SP>1</SP> arranged on endless belts 7,7<SP>1</SP> to maintain the corrugations produced by roller series 5,5<SP>1</SP> Resin-impregnated glass-fibre a is sandwiched between two sheets of cellulose acetate &c. by rolls 1,1<SP>1</SP> to form a laminate which is passed through the series of rollers, each series forming deeper corrugations, and is then received by corrugated mould halves 9,9<SP>1</SP> in a heated chamber in which the corrugated sheet material is polymerised. The height of the upper rolls from the axis of the lower ones may be varied by screw thread means, Fig. 4 (not shown), The mould halves 9,9<SP>1</SP> traverse the heating chamber under the action of rolls, rails, and guides and are non- rotatably secured to the belts by pins, Fig. 5 (not shown). Specification 871,751 is referred to.
