  • Patent number: 4761932
    Abstract: A capsule sealing machine (10) in which capsules (C) are fed from a supply hopper (16) to a rotating sealing table (12) for banding or sealing the capsules as they pass over a set of sealing wheels (13). The sealing machine has an improved capsule guide (22) for feeding the capsules from the hopper to the table, thereby reducing the cost and complexity of the machine while at the same time enabling a greater number of capsules to be sealed or banded in a given amount of time and space. The capsule guide comprises slotted magazine sections (23, 28 and 30) which are caused to vibrate by a vibrator (48) to promote discharge of capsules from the hopper and to advance the capsules along the slots. In one form of the invention, a capsule orienting device (51) is disposed in alignment with the magazine to orient the capsules in a desired end-for-end relationship before they are discharged onto the table.
