ABSTRACT:
Apparatus for advancing sections of newspapers has a first conveyor with equidistant grippers which deliver a series of suspended sections to a transfer conveyor. The latter delivers successive sections into successive pockets of a turret-shaped conveyor and comprises a driven shaft carrying two annuli of bearings for the stubs of two sets of plate-like clamping members. Each clamping member of one set cooperates with a clamping member of the other set to engage a section which is delivered by an oncoming gripper and to transfer the thus engaged section into a pocket of the turret-shaped conveyor. The clamping members of each set are pivotable relative to the shaft and orbit about the shaft when the latter is driven to advance the clamping members along an endless path. The devices for pivoting the two sets of clamping members during predetermined stages of each revolution of the shaft employ exchangeable stationary cams and followers provided on the respective sets of clamping members to track the cams. Pivotability of the clamping members relative to the shaft renders it possible to compensate for differrences between the speeds of the first conveyor and turret-shaped conveyor.
