The present invention relates to a measurement system for use in a corrugating machine and a corrugating machine and a method of checking the process for producing paper adhesions with such a measurement system. The measurement system according to the invention for use in a corrugating machine comprises a measurement device. The measurement device can detect electromagnetic waves in the infrared range here and is aimed at a region of a transportation device of the corrugating machine in the direction of transportation downstream of an adhesion station of the corrugating machine.

A plant for producing corrugated cardboard. The plant includes an arrangement for producing a corrugated cardboard web laminated on one side, the arrangement having a corrugating apparatus for generating a corrugated web, which has a corrugation, from a first material web, having a glue-applying apparatus for applying glue to tips of the corrugation of the corrugated web, and having a pressing apparatus for pressing a top web onto the tips, provided with glue, of the corrugated web. The plant furthermore has a severing apparatus which is arranged upstream of the corrugating apparatus and which serves for at least regionally severing the first material web in the transverse direction thereof.

A corrugated board sheet defect detecting device detects a defect in a single-faced cardboard sheet guided by a guide member with corrugated core paper facing outwards. The device includes a radiating device, an image capturing device, an image processing device, and an assessing device. The radiating device is configured to radiate light toward the core paper at a radiation angle relative to the single-faced cardboard sheet. The image capturing device is configured to capture an image of a portion of the core paper irradiated with the light. The image processing device is configured to a light portion and a dark portion in a direction in which the single-faced cardboard sheet is transported based on the captured image. The assessing device is configured to assess a quality by comparing a length of the light portion and a length of the dark portion.

An apparatus for forming a box or bag that is made of a substrate strip which includes a winder having a mandrel and posts that extend from the mandrel in a direction parallel to a winding and translation axis that rotate together as a unit around the translation axis. The apparatus also has a feeder that includes precursors and a gathering head used for forming the precursors into the strip and feeding the strip to the winder. A motor adjusts the feeder's angle relative to the winder in response to instructions from the controller based on the dimensions of the box or bag. This causes controlled overlap between adjacent windings of the strip on the posts. As the mandrel rotates, the posts draw the strip and wind the strip along a spiral having a length in excess of the depth. Zero waste of precursors is made possible by cutting the substrate perpendicular to its length and folding over the box or bag ends to form an angled seam with respect to the sides of the box.

A corrugated sheet processing apparatus is disclosed, comprising feed and guide rollers for selecting, moving and supporting sheets or webs to a corrugator for forming a corrugated sheet; and a control system for controlling the sheet processing equipment or a cutter; the sheet processing apparatus further comprising a visual inspection unit for reading printed information markers on at least one printed sheet or web as the printed sheet or web pass through the corrugated sheet processing apparatus, or corrugator; and wherein the control system further has a data look-up table whereby the apparatus can identify what products will be produced downstream of the visual inspection unit, and the required settings for the sheet processing equipment or corrugator for those products.

A cardboard sheet manufacturing system includes an information editing unit storing production state information, operation state information, and warping state information as acquisition information in a storage unit, the information editing unit deleting, in a case where the stored acquisition information includes prescribed information to be deleted, the information to be deleted from the storage unit and outputting the acquisition information stored in the storage unit as editing information. The system also includes an editing information storage unit storing the editing information output from the information editing unit, a prediction model calculation unit calculating a prediction model of the warping state based on the editing information stored in the editing information storage unit; and a control table update unit updating a target value of a control value of a control element in the cardboard sheet manufacturing apparatus, based on the prediction model.

The method includes the step of pulling the corrugated board along hot plates by means of an upper flexible member and a lower flexible member driven by two electric motors. By at least one electric parameter of the drive motor of the lower flexible member, the correct operation of the traction device and in particular the correct ratio of the linear feeding speeds of the two flexible members is checked. The method provides an iterative check of the controlled electric parameter and a possible correction of the speed of the flexible members to maintain the desired speed ratio.

A single facer equipped with a plurality of corrugated roll units each composed of a pair of corrugated rolls is provided with: a lifting/lowering device that causes each of the corrugated roll units to be lifted and lowered between a use position at which a core sheet is to be corrugated, a first position adjacent to and directly under the use position, and a second position adjacent to and directly under the first position; a horizontal movement device that causes each of the corrugated roll units to be moved horizontally between the first position, a third position adjacent to the first position on one side in a sheet transfer direction, and a fourth position adjacent to the first position on the other side in the sheet transfer direction; and a control device that controls the lifting/lowering device and the horizontal movement device to move the corrugated roll units.

A corrugated sheet processing apparatus (120) is disclosed, comprising feed and guide rollers for selecting, moving and supporting sheets or webs to a corrugator (136) for forming a corrugated sheet; and a control system for controlling the sheet processing equipment (136) or a cutter (148); the sheet processing apparatus (136) further comprising a visual inspection unit (162) for reading printed information markers on at least one printed sheet or web as the printed sheet or web pass through the corrugated sheet processing apparatus (136) or corrugator; and wherein the control system further has a data look-up table whereby the apparatus (120) can identify what products will be produced downstream of the visual inspection unit, and the required settings for the sheet processing equipment or corrugator for those products.
