Abstract

599,910. Moulding bearing jewels. ACES DEVELOPMENT CO., Ltd., and MARTINS, M. June 8, 1944, No. 10982. [Class 87 (ii)] [Also in Group XXIII] In the manufacture of instrument bearing jewels and the like from thermoplastic material, a rod p of the material is intermittently advanced into a zone between a die e and a plunger j where it is heated by burners wand becomes plastic. By means of a treadle a pivoted rod g is withdrawn from the die simultaneously with the advance of the plunger which thus causes the intrusion of the plastic material into the die. On the reverse movement of rod g and plunger the jewel is ejected: the jewels may be left as projections on the continuous strip of excess plastic material from which they can subsequently be broken off.
