Abstract

253,145. Gechter & K³hne Akt.-Ges., (Assignees of Meyer, O., and Schõfer, G.). June 8, 1925, [Convention date]. Stream-cutting machines extrusion machines; rolling machines. - A machine for dividing and moulding dough comprises a hopper leading to a series of feeding tubes through which the dough is extruded by screws, a reciprocating knife adapted to sever the extruded dough into portions, trays carried by endless aprons to receive the portions, and a moulding plate operating over the trays with a circular motion. As shown, the hopper 8 leads to a trough 6 divided by partitions into compartments each fitted with a screw 7 and a feed tube 9. The screws are driven simultaneously through worm gear 4, 5, preferably through interposed spring clutches so that the feed ceases upon excessive. pressure. A knife 10, supported by rods 11<1>, is reciprocated over the ends of the tubes 9 by cams 12 on a shaft 20 acting on levers 11 against the action of springs 17. Trays 29, supported by aprons 28, receive the dough portions, which are worked by a moulding-plate 31 supported upon crank pins 32 of members 33 driven from the main shaft 13 through gearing 16, 36, 35, 34. The aprons 28 are supported by rollers 18, 27 and are driven intermittingly through the roller 18, which is operated from the shaft 20 through a cam 21, lever 23, and ratchet gear. The plate 31 is preferably provided over each apron with a series of moulding-recesses 40 of progressively increasing depth; it is pressed down by springs 32<1> and is raised by levers 39 operated by cams on the shaft 20. The shaft 4 is driven from the main shaft through variable friction gear 1, 3.
