Versatile regulating unit for a stream of containers

A regulating unit inserted in an installation for preparing batches of containers of the bottle kind. The unit is interposed between an upstream conveyor and a downstream conveyor and at each of its ends, between two adjacent walls (16), includes a mechanism for centering each conveyor module (9). These mechanism includes arms (25) of the same length forming a pair of compasses between two adjacent walls (16), which pair of compasses has a central articulation secured to the conveying module (9) by a sliding connection located in the mid-plane of the corresponding lane. The walls (16) are connected to one another by a pantograph system (30) and a connecting member, having a link rod (35) extending between the pair of compasses and the pantograph to collaborate with the corresponding support of the conveying module (9) in order to keep it in the mid plane of the corresponding lane.
