Abstract

Successive foremost trays of a row of trays on the upper reaches of several endless belt conveyors are advanced away from the remainder of the row toward a lifting device by setting the conveyors in motion while a blocking device engages the remaining trays and holds them against movement with the conveyors. The blocking device can lift the remaining trays above the conveyors, or is provided with a profile which engages complementary profiles at the undersides of the remaining trays. A pawl holds the foremost tray against movement with the conveyors while the blocking device is disengaged from the trays behind the foremost tray.
