Method of lining closures |
摘要 |
A method and apparatus for molding and curing liners in cap closures includes a molding head having a plurality of molding stations, a feeding mechanism for feeding unlined caps with charges of lined material to the molding head and a take-off mechanism for removing the completed liner. The feeding mechanism consists of a dispensing unit which is capable of dispensing more than one-thousand charges of material per minute and includes a gun having a lining compound receiving chamber with a needle reciprocated therein. The needle is normally biased to a closed position and is electrically moved to an open position through a solenoid and a photosensing mechanism which accurately senses the position of a rotating wheel of the feeding mechanism.
