A counter ejector disposed at a downstream part of a box former, the counter ejector including a hopper that receives a sheet-shaped corrugated board box being transferred from an upstream side and fallen; and a blower that downwardly blows air to a hopper from above the corrugated board box, wherein the blower is capable of changing a blowing area to be blown along a transfer direction of the corrugated board box, and blows air to the blowing area corresponding to at least the front-end portion and the rear-end portion of the hopper in the transfer direction if the corrugated board box has a possible maximum size in the transfer direction.

Counter ejector and box former

A coating apparatus is provided in which entrained air flow of an applicator roll and a web is removed and occurrences of misting and coating irregularity are suppressed to thereby realize a uniform coating liquid film and a uniform coating state. A coating apparatus includes an applicator roll arranged to abut on another roll so as to form a nip portion therebetween and to transfer a coating liquid to be coated on a surface of a web passing through the nip portion. The coating apparatus further includes a coater head provided on an upstream side of the nip portion in a rotational direction of the applicator roll so as to supply the coating liquid onto a surface of the applicator roll and a boundary air remover provided between the nip portion and the coater head on the upstream side of the nip portion so as to prevent air from entering the nip portion. The boundary air remover includes a box part having an ejector ejecting an ejector gas on the surface of the applicator roll toward a direction reverse to the rotational direction of the applicator roll and also comprises a blade. The box part is constructed so as to cover a portion of the applicator roll.
