has been shifted to engage the wax surface 18 for softening same as at 18a prongs 23 remain in penetrating positions at this time a blade actuator appears at 32 in fig2 d the softened surface 18a has been engaged against and to adhere to the surface 20a of wax 34 tree 34 or carrier in fig2 e the prongs 23 have been retracted from the gate 15 and the supported heads are free to travel on conveyor 21 in the specific showings of fig4 9 the support body 22 is preferably attached to carrier 40 at locations 41 to pivot about horizontal axis 42 carrier 40 has spaced arms 43 to which support 22 is connected to pivot between a primary position see fig5 and 6 associated with one position of the carrier the gate 34 pick up 34 position overlying mold 14 and a secondary position associated with the other or first carrier position see fig9 the degree of such pivoting being between 10 u00b0 to 120 u00b0 for example a robot arm 45 articulated at 46 48 supports the carrier to such transport the arm being pivotally connected at 49 to base 50 to swing about a vertical axis 51 the blade 31 is pivotally attached at 52 to the underside of bracket 53 carried by arms 43 to swing between a retracted position 31a within a heater structure 30 and an advanced position 31b corresponding to fig2 c softening the bottom surface 18 of the gate ultimately the support tree 20 with the wax head replicas supported thereon is coated with ceramic the wax is melted out and the ceramic.
