PCT No. PCT/SU86/00005 Sec. 371 Date Sep. 17, 1987 Sec. 102(e) Date Sep. 17, 1987 PCT Filed Jan. 30, 1986 PCT Pub. No. WO87/04660 PCT Pub. Date Aug. 13, 1987.Apparatus for the pressure-forming and curing of polymer products incorporates two moulds (1) and a forming device, the moulds (1) being sturdily linked to each other with provision for setting the separating distance as required and for revolving on a fulcrum pin (9) so that the material of a circular product can be wound therearound. The moulds (1) are semicylinders which face each other with their flat sides and are sturdily interlinked by two parallel plates (2) so as to form integrally therewith a sturdy building core having a contoured outside surface. The forming device is a girdling structure which embraces the semicylinders (1) and the plates (2) circumferentially and is made up of at least two elements at least one whereof is located with provision for radial displacement in the course of pressure-forming.
