  • Patent number: 5261211
    Abstract: The invention relates to a method for manufacturing subcutaneous capsules. The capsules are produced by cutting from a silicone tube lengths in excess of the final capsule length. The lenghts are arranged into rows including a defined number of them and in these rows they are filled and sealed. One end of the capsules is first sealed by glue dosaged into their openings. The material for the capsules is dosaged by an aperture disc glidable on a plane surface. By sweeping the upper surface of the disc the dosage volume is limited to the volume defined by the aperture. To regulate the packaging density of the material vibration may be used during the filling of the apertures. The dosaged material is conveyed to the capsule via a feeder funnel, through which a rotatable spiral spring, functioning as a filling screw, is inserted into the capsule to be filled.
