Abstract
Apparatus for draping blanks around blocks of parallel cigarettes has a continuously driven turret with radially inwardly extending pockets in its peripheral surface. Successive pockets of the turret receive blocks of cigarettes from successive pockets of a first endless belt or chain conveyor which partially overlies the peripheral surface of the turret and carries pushers which transfer the blocks into the pockets of the turret in the region of overlap. First blanks are caused to overlie the pockets of the turret ahead of the region of overlap so that the blocks deform the blanks during transfer into the pockets of the turret. The blanks are provided with flaps and tucks during travel with the turret, and the latter is further overlapped by a portion of a second endless belt or chain conveyor whose pockets receive blocks and the at least partially draped first blanks from the pockets of the turret in the region where the second conveyor overlaps the peripheral surface of the turret. Second blanks are placed across the pockets of the turret ahead of the region of overlap with the second conveyor, and such second blanks are automatically draped around the blocks and the respective …
