<P>PROBLEM TO BE SOLVED: To securely convey sticky product material not suited for vibrational conveyance. <P>SOLUTION: A weighing arrangement includes an infeed for weighed product material and at least one dosing mechanism 3 for controlled conveyance of product material portions from the infeed to a weighing system. The dosing mechanism 3 includes a motor-driven transport screw 5 formed as a helically-shaped rod positioned in an open trough for conveying the product material from the infeed to the weighing system, and a control unit for controlling the motor in order to deliver a desired portion of product material to the weighing system. This weighing arrangement provides a gentle, well-defined conveyance of product materials that are not suited for vibrational conveyance or conveyance by a screw conveyor in a tubular housing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
