  • Description: 818,167. Moulding fibrous articles. BRODRENE HARTMANN A. S. Feb. 27, 1957, No. 6633/57. Class 87(2). [Also in Group XXX] Relates to a pulp-moulding machine comprising a rotatable carrier 18 for suction dies 38 which are moved through a vat 40 containing liquid pulp, and at least two other rotatable carriers 20, 22 for transfer dies 42, 50 by which the blanks taken up on the suction dies are transferred successively to a depositing place where they are thrown off onto an endless conveyer 52 which carries them through a kiln. According to the invention, the conveyer consists of trays 58 which are suspended on chains 55 and are horizontal at and near the depositing place, and the arrangement is such that when a blank is being thrown off the diecarrier it is located a short distance vertically over and parallel to a tray on the conveyer, so that the still moist blank is not distorted on impact with the conveyer. The .trays are freely swingable and constantly kept horizontal by means of counter-weights 60. The conveyer 52 and the rotating members are driven from the same electric motor, the gearing being so constructed that the peripheral speed of the die 50 is equal to the speed of the trays 58. The distance between the die and the tray is made adjustable by mounting. the two front chain wheels 56 on a frame 64 which is swing- able about a pivot by rotation of a shaft 88 which through gearing 92 rotates screws 94 and so raises or lowers the frame 64. The chain wheels 56 are attached to gear wheels 76 which engage gear wheels 78 fixed to a shaft 82 mounted on the main frame. This shaft is driven from a motor-driven chain wheel 34 mounted loosely on the shaft 82, by means of a worm-wheel 100 fixed to the chain wheel 34, a worm 102 adjustable by a handle 118, and a clutch 104, 110 one part of which carries the worm. When the distance adjustment is made, the gear wheels 76 will roll on the gear wheels 78, resulting in a movement of the chains 55 and thus a phase displacement of the trays 58. To adjust the phase to the desired value, the worm 102 and worm wheel 100 are rotated, so as to rotate the shaft 82 and chain wheels 56 in relation to the stationary chain wheel 34.
