Abstract

380,825. Moulding artificial resin by hopper-and-plunger machines. KOPP, P., 3, Stubenrauchstrasse, Friedenau, Berlin. March 24, 1931, No. 9056. Convention date, Nov. 7, 1930. Addition to 380,824. [Class 87 (ii).] The apparatus of the parent Specification is modified by arranging the discharge opening of the mould at right angles or at a substantial angle to the direction of pressure. Fig. 2 shows a plunger B with bevelled rear end forcing the material P through the outlet die C. Fig. 3 shows a pair of co-operating dies A, B which receive partly-compressed articles D or successive charges of material pushed between them in succession by a ram H. The dies complete the compression to produce the finished article, each charge being partly compressed and also partly heated by the bevelled portion of the die on the one stroke and finally compressed and more strongly heated by the flat portion on the succeeding stroke. Heating and cooling channels F, G are provided. Metal inserts may be positioned in the partly-compressed articles before the final pressure is applied.
