Abstract
In a system for filling granular material into hard gelatin capsule wherein the granular material is portioned to a predetermined quantity by volume in a metering chamber and the portioned granular material mostly gravitates to a body of the hard gelatin capsule positioned beneath the metering chamber, an artificial force is exerted by a pusher rod on the granular material remaining in the metering chamber after the beginning of the gravitation. There also is an improved system for adjusting the capacity of the metering chamber. The improvements result in a greatly increased number of capsules which may be handled and filled at a time, a reduction in time required for the process and correspondingly in area occupied by the machine, and a remarkable improvement in the productivity. The uniformity and accuracy in the quantity of the granular material actually filled in the capsule are also remarkably improved.
