  • Receptacle forming apparatus having split receiver
    Patent number: 4440290
    Abstract: A split receiver mounted on an indexible rotary turret of a paper receptacle forming machine has a cylindrical bore which opens radially outwardly of the turret. One part of the receiver, mounted in fixed position on the turret, defines the inner end portion of the bore. Another part, supported for movement into and out of mating engagement with the one part cooperates with the outer end portion of the one part to define the outer end portion of the bore. A camming mechanism operates in response to indexing movement of the turret to move the one part out of mating engagement with the other part and from a receptacle holding position to a receptacle releasing position.
