Abstract

<PICT:0693486/III/1> <PICT:0693486/III/2> In a method of making endless flexible seamless tubing (see Groups V and XXII) an inner coating of for example, natural or synthetic rubber may be applied from nozzles such as 29, Fig. 7, carried by the shaft 6 which carries the internal corrugating rolls, the tubing passing through a hot or a cold zone before or after the lining is applied, depending upon the lining material being used. The shaft 6 may have more than one base, Fig. 9, allowing additional substances to be introduced if necessary, to assist in hardening the lining.
