Abstract

551,499. Moulding corrugated rubber tubing; vulcanizing. COW & CO., Ltd., P. B., and HUIZINGA, W. A. July 23, 1941, No. 9349. [Classes 70 and 87 (ii)] Corrugated rubber tubing, e.g. for respirators, is made by locating a tube of uncured rubber within a corrugated mould, supplying fluid under pressure to the interior of the tube so that the tube is expanded into intimate and direct contact with the mould, and then removing the rubber from the mould and curing it. Apparatus suitable for carrying out the invention includes a mandrel 5 having perforations 7 through which pressure fluid passes. The curing operation may be performed in two steps. First, the tubing is removed from the mandrel 5 and collapsed longitudinally (to make it less liable to deformation during vulcanization) with the aid of flanged rings which are placed over the ends of the tubes and secured together by a quick-release bolt ; the tube, disposed with its axis horizontal to ensure uniformity in the corrugations, is then partly cured, whereby it is given a slight set. Second, the partly cured tubing is threaded on a mandrel and pulled out to a length greater than the required finished length (to overcome the initial set given in the first step) and vulcanization is completed, thick tubes being held with the axis horizontal and thin tubes with the axis either horizontal or vertical. If one end of the finished tube is to be of different diameter from the other, e.g. to connect the filter box to the face piece in a "service" respirator, the flanged rings used in the first vulcanizing step may be fitted with bushes of the required diameters, and the mandrel used in the second step is provided at one or both ends with bushes to take the ends of the tubing. According to the Provisional Specification, the collapsed tubing may be held in the vertical position during the first vulcanizing step.
