20150053349 | CORRUGATED SHEET MANUFACTURING APPARATUS - The present invention provides a corrugated sheet manufacturing apparatus ( | 02-26-2015 |
20140326119 | CORRUGATED PAPERBOARD BOX MAKING MACHINE - Disclosed is a corrugated paperboard box making machine, which comprises: a slotter for slotting a corrugated paperboard sheet to form slots, a die-cutter disposed downstream of the slotter, the die-cutter including a die cylinder with a punching die and an anvil cylinder; a cutting blade for cutting, in cooperation with the anvil cylinder, the corrugated paperboard sheet slotted by the slotter, into two small-size corrugated paperboard sheets, along a direction perpendicular to the conveyance direction; and a lifting and lowering mechanism for lifting and lowering the cutting blade in such a manner as to allow a position of the cutting blade with respect to a corrugated paperboard sheet being passing through the anvil cylinder to be changed between a cutting position where the cutting blade is permitted to cut the corrugated paperboard sheet, and a non-cutting position where the cutting blade is precluded from cutting the corrugated paperboard sheet. | 11-06-2014 |
20140162862 | CORRUGATED PAPERBOARD BOX MAKING MACHINE, AND INTER-SHEET PACING DEVICE THEREFOR - Provided is a corrugated paperboard box making machine which comprises: a cutting device for cutting one corrugated paperboard sheet into a plurality of small-size corrugated paperboard sheets along a direction perpendicular to a predetermined transport direction; a folder-gluer for bending and gluing each of the cut small-size corrugated paperboard sheets; a counter-ejector for stacking the glued small-size corrugated paperboard sheets to form a batch of the small-size corrugated paperboard sheets; and an inter-sheet spacing device for spacing the small-size corrugated paperboard sheets apart from each other, between the folder-gluer and the counter-ejector. The inter-sheet spacing device comprises a transport section for transporting the small-size corrugated paperboard sheets from the folder-gluer to the counter-ejector, and a speed adjustment section for adjusting a transport speed in at least one of the folder-gluey and the transport section so that the transport speed in the transport section becomes greater than that in the folder-gluey. | 06-12-2014 |
20140037353 | CORRUGATED PAPERBOARD SHEET PRINTING DEVICE, CORRUGATED PAPERBOARD SHEET BOX MAKING MACHINE, AND MANAGEMENT DEVICE FOR CORRUGATED PAPERBOARD SHEET BOX MAKING MACHINE - Provided is a corrugated paperboard sheet printing device which includes a conveyance device for conveying a corrugated paperboard sheet fed out from a sheet feeding device, while suckingly holding the sheet; a plurality of printing units for printing the sheet through a series of printing processes; an information generator for generating basis weight information indicative of a basis weight of a corrugated paperboard sheet in each order; a storage device for storing therein a plurality of correction information for correcting a plurality of printing timings at each of which a respective one of the plurality of printing units performs the printing process on the sheet, in association with the basis weight information; and a controller for, based on the correction information, correcting the printing timing in each of the printing units, and causing the printing unit to operate according to the corrected printing timing. | 02-06-2014 |
20090120263 | SCORER APPARATUS FOR CORRUGATED PAPERBOARD SHEET - Disclosed is a scorer apparatus for scoring a surface of a corrugated paperboard sheet (DS) being continuously fed along a feed line. The scorer apparatus comprises a plurality of scorers each adapted to be displaced to a given position in a crosswise direction of a corrugated paperboard sheet, and made up of a pair of upper and lower segments ( | 05-14-2009 |
