Accordingly, a superimposed veneer is obtained in which the parallel veneer and the cross veneer are bonded with a high degree of adhesion and corresponding edges of the parallel veneer and the cross veneer substantially align with each other.

A sheet conveyance apparatus includes a first conveyance portion configured to convey a sheet, a second conveyance portion configured to convey the sheet, the second conveyance portion including an abutment portion configured to form a loop on the sheet by being abutted against a leading edge of a sheet conveyed by the first conveyance portion, a curved guide portion, which is curved, configured to guide the sheet conveyed by the first conveyance portion to the second conveyance portion, and a rotary member arranged downstream of the first conveyance portion and upstream of the second conveyance portion in a sheet conveyance direction, and configured to be driven to rotate by a surface of the sheet that is guided by the curved guide portion, the surface sliding against the curved guide portion.

A corrugated cardboard sheet feeding apparatus, which comprises: an upstream-side conveying unit which conveys a corrugated cardboard sheet mounted on delivery rollers; and a downstream-side conveying unit which is adjacent to the downstream side of the upstream-side conveying unit and conveys, to a sheet processing unit, the corrugated cardboard sheet delivered from the upstream-side conveying unit. The downstream-side conveying unit has: a downstream-side suction unit which has openings facing a sheet conveyance path; and feed rollers with a portion of the outer peripheral surfaces thereof protruding towards the sheet conveyance path, which are accommodated in the downstream-side suction unit. The distance between the downstream ends of the openings and the axis of the most-downstream-side delivery rollers is set to be not larger than the maximum range of the distance between the conveyance rollers of the sheet processing unit.

A system includes an image forming station, which is configured to apply droplets of one or more printing fluids to a target substrate, so as to form an image thereon, and a substrate conveyor, which includes one or more perforated plates having multiple openings, and is configured to grip and move the target substrate to and from the image forming station for forming the image, the substrate conveyor includes one or more rotatable elements, which are fitted in the respective openings, and are configured to provide mechanical support to the target substrate, and when the target substrate moves over the one or more rotatable elements, at least one of the rotatable elements is configured to rotate in response to a physical contact with the target substrate.

A transmission device of a developing machine is disclosed. The transmission device includes a plurality of transmission units with bearing points thereof arranged on an identical surface to form a bearing surface for transmitting a substrate, and each of the plurality of transmission units comprises a supporting rotating axle and a roller connected with the supporting rotating axle, and the supporting rotating axle has a central rotating axis. A developing machine is also disclosed.

A medium-transport apparatus includes: an apparatus main body having the transport path for transporting the medium; and a cover CV provided on the side surface of the apparatus main body and configured to be switched between a first state of exposing the transport path and a second state of covering the transport path. The cover CV is divided into: a first cover that has the rotation shaft along a Z-axis and is rotatable with respect to the apparatus main body; and a second cover that is arranged on a Z side of the first cover, has the rotation shaft along a Y-axis on the Z-side, and is rotatable with respect to the apparatus main body.

A self-contained no-feed-roll computer controlled corrugated board or paperboard sheet feeder apparatus 200 is configured to upgrade an installed corrugated board processing machine (e.g., 10) and includes a feed table surface 210 for boards (e.g., 2) having drive wheels (222W, 224W, 226W) in an initial variable velocity zone 220 which drives the board in a first motion profile through a first vacuum zone, and a second velocity zone 230 which then drives the board in a second motion profile through a second vacuum zone Retrofittable sheet feeder 200 also includes a controller 300 configured to receive predetermined velocity signals from the host machine 10 and generate (i) a first initial variable velocity control signal for initial variable velocity zone 220 and (ii) a second velocity control signal for second velocity zone 230 in response.

A sheet conveyance apparatus includes a first conveyance portion configured to convey a sheet, a second conveyance portion configured to convey the sheet, the second conveyance portion including an abutment portion configured to form a loop on the sheet by being abutted against a leading edge of a sheet conveyed by the first conveyance portion, a curved guide portion, which is curved, configured to guide the sheet conveyed by the first conveyance portion to the second conveyance portion, and a rotary member arranged downstream of the first conveyance portion and upstream of the second conveyance portion in a sheet conveyance direction, and configured to be driven to rotate by a surface of the sheet that is guided by the curved guide portion, the surface sliding against the curved guide portion.
