Abstract
Tubular blanks, from which containers to be filled and closed are set up, are stacked in flat condition inside a magazine (3), so that they rest on supporting bars. A back edge of the lowermost blank of the stack is engaged by a pair of lugs mounted on a belt conveyor situated under the magazine, so that the lugs protrude upwards beyond a rest plane defined by the supporting bars. The lowermost blank is stripped by passing it through a passage delimited by the supporting bars and stops situated above the supporting bars, and aimed at stopping blanks of the stack situated above the blank just withdrawn. The belt conveyor carries the withdrawn blank through following working stations.
