Abstract

Perforated rubber sheeting is made by spraying latex or the like on to a perforated base of metal, celluloid, ebonite or the like, causing the rubber to set, and stripping the sheet from the base. Natural or artificial dispersions, which may be compounded, and also vulcanized, may be employed. The base may be plane or shaped, and engraved or embossed, and the perforations may be chamfered, countersunk, fluted, or grooved. To ensure that the perforations are not blocked, a gas such as air may be passed through them from the coated side. The sheet may be coated while still tacky, with a fibrous or powdered material, such as silk, cotton, wool, asbestos, carbon, mica, glass, metal. A decorated surface may be obtained by spraying the last coat of a different colour through a second perforated plate, spaced away from, or close to the surface. Specification 405,970, [Group VIII], is referred to.
