  • Patent number: 4251977
    Abstract: End closures for cans fed horizontally at given intervals at a high speed are shifted in direction, one after another, to be substantially perpendicular to a support passage extending substantially horizontally, received separately by the passage rapidly and positively, and lotted out when a predetermined number has been reached by the pieces received. Each lot thus compacted to a solid cylindrical form is put into an elongate paper bag, and the open end of the bag is closed.
