Abstract: 1370251 Forming pastry cones NABISCO Inc 14 April 1972 17388/72 Heading B5A [Also in Divisions A2 and B8]  Apparatus for forming pastry cones comprises a conveyer moving continuously at a constant speed and carrying a plurality of moulds and cores, first means to remove the cores from the moulds and store them on the conveyer and second means downstream of the first to remove the cores from the conveyer and reinsert them in the moulds. As shown in the Figures, the apparatus comprises a mould filling section 10, an oven 11 and a conveyer 12 for removing baked and trimmed cones from section 10. A chain conveyer 20 carrying moulds 40 passes over driven sprockets 16, 19. The moulds 40 comprise a fixed, leading half 47 and a half 49 pivoted thereto at 51 and are mounted in transverse sets of ten on mould bars 45. Core bars 86 carry cores 41 which are placed on the moulds 40 except for a part of section 10 where they are removed and placed on following U- shaped supports 134 on the conveyer to enable removal of the product and refilling of the moulds before replacing on the following moulds. The moulds are retained shut by curved springs 52 and are opened by rollers 64 on levers 56 engaging cam tracks 80 and reclosed on engagement with ramp 84. The core bars 86 are locked to the mould bars 45 by finger 107, Fig. 23, of latch 104 pivoted to bar 86 which engages pins 109 on bar 45. Release of the locking means is effected by means 114, surface 116 of which depresses core bar 86 by engaging roller 100 thereon, freeing finger 107 and latch 104 is then raised by ramp 126 engaging ear 112 on latch 104. Core bars 86 are then raised by members 141a, Fig. 12, having notch 150a to receive rollers 100 and placed on supports 134 immediately following the moulds from which they were taken. Simultaneously with this movement, members 141b raise bars 86 from the storage supports 134 and place them on following moulds 40. After removal of the cores, the finished cones 42 are removed by suckers 195 on tube 198 connected to a vacuum source by flexible conduit 202, and placed by air from conduit 236 on discharge conveyer 237 having partitions 532 and then pass to trimmer 539. Batter is metered from pump assembly 244 into the open moulds, pump 244 moving in the same direction and at the same speed as the moulds. Pump assembly 244 may be indexed transversely so that successive moulds in a moving longitudinal row may be charged from different pumps, e.g. with different composition, texture and/or colour. Core bars 86 are then replaced on following moulds as above described. Thereafter, rollers 100 on core bars 86 enter core bar jogging track 406, 407 which is movable vertically to jog the cores to allow gas and steam to escape from the moulds before core bars are locked upon the moulds. The core bars are centered thereon by means (458, Figs. 30, 31, not shown). The core bars are locked by track 475 depressing roller 100 thereby allowing latches 104 to pivot and fingers 107 to engage pins 109 on the mould bars. Latch 104 is fully locked in position by roll 476 pressing on lug 480 on latch 104. The latch position is detected by means 483 (Figs. 28, 29, not shown) which would stop the machine if necessary.
