In a dip treating apparatus for carrying out a multiple-step process, e.g. for film processing, the objects to be treated are transferred in separate groups step by step through a row of stations by means of a series of individually operatable conveyors, one for each adjacent pair of stations. Each such conveyor comprises a vertically extending guideway along which a slide member is reciprocatable by means of a working cylinder, the piston of which is pneumatically driven at an operating speed controlled by a flow of liquid through a variable restriction. The slide member of each conveyor carries a rocker swingable about a transverse horizontal axis and including a pair of downwardly extending rocker arms having means at their lower ends for catching the various groups of objects to be treated and transferring them from one station to the next, the swing axis of the rocker being always above the level at which the various groups of objects are picked up and delivered by the catching means of the related rocker. The slide member further carries an arm serving as a splash-shield between adjacent stations and operative to restrict any excessive swinging motion of the groups of objects at their transfers. |
