ABSTRACT:
In a machine for handling objects conveyed through the machine, there is a spacing device for the objects which includes at least one lever pivoted on a spreading section of an entrainment unit. The lever is elastically stressed in a position such that a first portion thereof is normally moved toward the interior of the machine and inserted in the path of travel of the objects while a second portion thereof bearing a passive stopping device and located upstream from the first is normally moved toward the exterior of the machine and outside the path of travel of the objects. When a first object meets the first portion of the lever moving it outwardly, the second portion of the lever is moved inwardly in such a manner that the stopping device can prevent advance of a second object until the first object reaches a desired distance.
