摘要：A sack (11) is filled with pulverulent material, e.g. cement from a container (7) asthe sack is carried around a path suspended from a filling spout (8). The weight of thefilling in the sack is measured by a load cell (10) which transmits a weight signal via a
damper (14) and computer unit (20) to a comparator (13) which closes a filling valve (9)when the weight of filling reaches a preset weight determined by a setting unit (12). Afterthe sack has been filled it is immediately check weighed whilst still on the spout (8) and afeed-back unit (15) resets the setting unit (12) to compensate for any difference betweenthe actual and desired weight of filling.
