Abstract

Boots, shoes, &c. are made wholly or partly of caoutchouc by pressing up the caoutchouc between movable outer moulds and a hollow last previously covered with the necessary layers of fabric and caoutchouc, the last being inflatable to effect the moulding operation. Reference has been directed by the Comptroller to Specifications 305,908 and 309,821, [both in Class 87 (ii), Moulding plastic &c. substances].
