Abstract
895,821. Preheating moulding material. GILBERT, N. W. May 5, 1958 [May 4, 1957], No. 14289/57. Class 87(2). [Also in Group XI] Thermosetting moulding material is preheated prior to moulding by pushing pellets of the material from a trough 15 through an electrically heated cylinder 3 by means of a piston 22. The preheated pellets are discharged on to a trough 18. The temperature is thermostatically controlled. Two cylinders may be mounted side by side. A thermometer may be provided.
