Abstract
A metering operation in a capsule filling machine is controlled based on a correction signal derived from capsules just filled with material and ejected therefrom, by sampling/weighing these capsules, and by processing the weighed value to generate correction signal wherein: a first step of sampling/weighing is performed at the start-up stage of the capsule filling machine by collectively weighing a plurality of capsules sampled in bulk at once, and the second step of sampling/weighing is performed in subsequent steady operation stage by individual weighing each capsule from the bulk one by one. An apparatus for performing the method has a sampling chute bifurcated in alternatively switchable two paths; i.e., a direct path and a controlled path, which share a common terminal i.e., a scale pan of a balance. The first step of sampling/weighing is performed in the direct path to the pan and then said second one is made through the controlled path having a gate means which permits intermittent and individual passage of capsules.
