A method and apparatus for applying a reinforcing liner blank on a moving box blank and shifting the assembled blank into the desired position for a subsequent attachment together characterized by a first belt moving a box blank in one direction, a second belt moving a liner blank and guiding it into surface-to-surface engagement on the moving box blank and the belts coacting to move the box blank and with the liner engaged thereon and cooperating with a shifting device which moves the blanks relative to each other to the desired position prior to joining the blanks together. The shifting device includes at least one endless chain belt having an abutment for engagement by the leading edge of the box blank and a second abutment for engagement by the leading edge of the liner blank which abutments coact with the respective belts to cause slippage of their respective blank on the belt when the leading edge is engaged. Preferably, the apparatus and method include a device for sequentially feeding a box blank into a transporting device which includes the belt engaging the box blank and a similar feeding device for sequentially feeding liner blanks into a transporting device which includes the belt for moving and guiding the liner blanks into the surface engagement with the box blank. |
