Abstract
An apparatus for serially conveying receptacle lids includes two lid-advancing wheels each having a plurality of circumferentially spaced peripheral pockets for receiving individual lids. The wheels peripherally adjoin one another in a border zone for transferring the lids from one wheel to the other. The apparatus further has a supporting surface situated underneath the wheels for supporting the lids as the lids are advanced by the wheels. An annular guide surrounds the wheels externally of the border zone for retaining the lids in the wheel pockets. A pin is mounted on at least one of the wheels at one of the pockets thereof; the pin is held displaceably relative to the wheel carrying the pin. Further, the pin has an upper position for engaging a radially inner part of a shoulder of the lid to retain the lid in the pocket adjoining pin. Further, the pin has a lower position for releasing the lid shoulder to allow a displacement of the lid relative to the pocket. A control device displaces the pin during rotation of the wheels.
