Abstract

488,422. Moulding hollow rubbber articles. HUNGARIAN RUBBER GOODS FACTORY, Ltd. Nov. 6, 1936, No. 30313. Convention date, Nov. 6, 1935. [Classes 70 and 87 (ii)] Hollow rubber articles such as toys are formed from rubber sheets, the pre-stamping, inflating, stamp-welding, and vulcanizing being carried out in a single working operation in the same mould. The mould comprises two steel half moulds I, II having a number of mould cavities a and provided with sharp edges f and blunt edges g for stamp-welding the sheets. Heating-channels h are provided for the steam used in the vulcanization and for cooling water, and channels e, e<1> are provided for releasing air entrapped by the sheets. During moulding, hollow needles are introduced between the rubber sheets to fill them with compressed air in known manner. Very fine needles may be inserted through the channels l after vulcanizing to puncture the articles and release part of the compressed air. The space m between the mould cavities may be divided by cutting-edges p so as to render the waste rubber easily removable. The rubber is vulcanized for about two minutes at a temperature of 170‹ C., and then cooled to 60‹ C. The moulds may be placed between heated platens or be heated electrically. Rubber whistles may be inserted in the articles. Specification 24169/95, [Class 87], is referred to.
