  • Handling partly completed containers
    Patent number: 5613828
    Abstract: Successive flat skillets (S) are picked from a stack (12) and fed to a conveyor (2) by a mechanism which has devices gripping adjacent side faces to a fold line of a skillet to open the skillets to their tubular form during the transfer movement. The gripping devices (22,24) pivot on an axis coincident with the skillet fold line to allow the skillet to be opened to its full tubular form without distortion. The mechanism is so arranged that the skillet reservoir stack (12) can be oriented in a plane substantially parallel to the conveyor path for the opened skillets, in order to minimize space requirements.
