ABSTRACT:
A selector mechanism for controlling transfer of articles from a plurality of upstream feed lines to at least one downstream feed line (104) comprises a plurality of transfer passages (114) each provided with a gate (106) and at least one stop (108). The gates (106) are operable to block the leading article in the respective transfer passages while the stops (108) are operable to arrest movement of a trailing article and hence the articles that follow it. Operation of the gates (106) and stops (108) is co-ordinated so that the stops are operative when the gates are operated to unblock the leading article. In this way, the number of articles freed for onward movement each time the gates are operated to unblock the path of conveyance can be controlled.
