Abstract

316,134. Pick, P. July 23, 1928, [Convention date]. Moulding indiarubber and the like.-A sheet material resistant to air, water, acids, &c. is made by pressing sheets of plastic material such as unvulcanized rubber on both sides of a perforated metal sheet by means of a hydraulic press in vacuo and hardening by vulcanizing or otherwise. Several layers of plastic material may be employed, the layers being of different degrees of hardness. The layers are welded together, and the layers on the two sides are connected through the perforation in the plate. Fig. 7 shows a press suitable for the process. The sheet 1 to be coated rests on ledges 14 in a chamber 4 provided with a tight fitting door and a pipe 7 connected to an air pump. One set of sheets of plastic material 3<1>, 3<11>, 3<111> are laid on the plates 1 and covered with a plate 20 and the others laid on a plate 15 on the platen of the press. The plate, 15 is provided with a rib 16 sliding in a groove in the platen, so that it can be placed accurately in position. Sheets of vulcanized rubber &c. prevent the plastic material from sticking to the plates 15, 20. The plates 15, 20 are provided with slots 22, 23, which arrest the motion of the platen when the material has been compressed to the desired extent. Heating coils 25 are provided. The press forms the subjectmatter of the Specification 335,996, [Class 69 (ii), Hydraulic presses &c.]. The Specification as open to inspection under Sect.. 91 (3) (a) describes the use of a mixture of linseed oil, asphalt and chalk for the plastic material, and of wire fabric for the metal skeleton and comprises also the subject-matter of the Specification 339,320, [Class 66, Hollow-ware]. This subjectmatter does not appear in the Specification as accepted.
