Abstract

A control arrangement for a control member for opening and closing of the exit of a feed channel communicating a closure magazine and a closure transfer device, especially for apparatus for closing containers such as bottles and the like to which a closure is to be secured. The control member is controllable by means of an opto-electric sensor arrangement which is actuatable by a proximity switch which, in turn, is actuatable by a control cam. The sensor is arranged at such a distance away from the point of tangency of the pitch circles respectively prescribed by the transport wheel and the rotating securing devices, laterally of the transport path of the transport wheel and its beam is directed transverse to the transport path to strike a container held by the transport wheel to project from the upper side or the lower side thereof, such that the control member is retained in its open position when a container is sensed and, when the absence of a container is sensed, i.e. when a pertaining pocket of the transport wheel is not occupied by a container and the beam is reflected, the control member assumes its closed position for the closure intended for an absent container.
