Abstract: A counter ejector is configured to receive a sheet-shaped corrugated board box forwarded from an upstream side by the hopper and to eject the sheet-shaped corrugated board box in units of batch. The counter ejector includes a front stop defining a hopper for stopping the sheet-shaped corrugated board box forwarded from the upstream side; an elevator including a mount that receives the sheet-shaped corrugated board box falling after hitting the front stop; a ledge activated when the number of sheet-shaped corrugated board box forming a stack piled on the mount reaches a predetermined number for receiving a sheet-shaped corrugated board box that is to form a next stack; a support ledge disposed under a front of the hopper for receiving the stack formed on the ledge; and a position setting mechanism that variably sets a vertical position of the support ledge.

Abstract: 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.

Abstract: In an apparatus for applying a film of coating solution to each side of a web such as paper, resin film, etc., there is provided an air-flotation type mini turn bar (4) to the downstream side of the nipping portions (20) of two applicator rolls (2,2). The air-flotation type mini turn bar (4) is used to convey the web (1) while holding the web on the surface of one of the two applicator rolls (2), after it passes between the nipping portions (20). In this way, the occurrence of flaws in the coated surfaces of the web (1) is prevented, the occurrence of a mist and coating unevenness is suppressed, and a film of coating solution is formed evenly on each side of the web.
