Method for producing logs (B1, B2) of continuous thin products, or web products, in optimized manner by tracking defects in the surface and/or in the thickness detected on the products, comprising a step of continuously winding a thin product (T) into logs (B1, B2) on a winding machine, in order to produce at least one primary log, a step of identifying any defects in the surface and/or the thickness of said continuous thin product, a step of storing in a database system (31), outside the primary log, information related to said defects comprising at least the position of said defects with respect to a reference system associated with the primary log, a step of assigning a primary ID code to said primary log, a step of marking said primary log with said primary code, a step of associating, in said database system (31), information on said defects with the primary ID code of the primary log, so that, in said database, to a given primary ID code information are associated related to defects in the surface and/or the thickness of the respective primary log, that can be identified based on their position on the primary log, a step of using said information on the defects of the primary log, stored in the database system (31), in order to optimize at least one subsequent processing of the product wound into the respective primary log, said use providing for recognizing the primary code of the primary log being processed and the processing of the product based on the information on the surface defects associated to the primary log.

To provide a marking device that enables to easily find a tag determined as defective (RFID error, etc.) among a plurality of tags that are stacked or the like. The marking device to use with a sheet includes cut and raising part for forming, as a failure process, a cut and raised section to be positioned at an edge of the sheet having been found the defect.

A recording-medium-container device includes a container configured to contain a stack of recording media; a blower configured to blow gas to the recording media contained in the container; and an image capturer movable in a stacking direction in which the recording media are stacked in the container, the image capturer being configured to capture an image of the recording media while the recording media are being blown with the gas by the blower.

According to one embodiment, there is provided an image forming apparatus including a conveyance unit, a detection unit, an image forming unit, and a control unit. The conveyance unit is configured to convey a print medium to which a wireless tag is attached and on which wireless tag position information indicating a position of the wireless tag is formed. The detection unit is configured to detect the wireless tag position information formed on the print medium. The image forming unit is configured to form an image on the print medium. The control unit is configured to control the conveyance unit and the image forming unit based on the wireless tag position information detected by the detection unit.

A bill processing apparatus which is capable of reliably supplying information on a bill to the bill housing body side. The paper sheet processing apparatus has a bill housing part being capable of housing a bill inserted from a bill insertion slot, and also a reader/writer which wirelessly transmits information on the bill inserted from the bill insertion slot. The bill housing part has a coil antenna which wirelessly receives the information transmitted from the reader/writer, and a storage part which stores the information on the bill received from the coil antenna.

The present invention relates to a system (200) and computer implemented method for monitoring the performance of at least one winding spool (120) in the reel section (100) of a paper machine, by detecting a unique identification code, ID, associated with the winding spool (120) from a marker (130) on the winding spool (120); identifying the winding spool (120) based on the unique identification code, ID; determining at least one winding spool performance parameter for the identified winding spool (120) based on measurements from at least one sensor (160); and determining if there is a failure of the performance of the identified winding spool (120) based on if the determined at least one winding spool performance parameter fulfils a requirement indicative of failure of the performance of the winding spool (120). The invention further includes a computer program comprising software for executing the method, a non-volatile data carrier, and a paper machine comprising the system.

A sheet processing apparatus for processing sheets each with a wireless tag includes a roller, a wireless tag reader/writer, and a controller configured to control the roller to convey a first sheet with a first tag along a path, control the reader/writer to acquire first strengths of radio signals received from the first tag during the conveyance and second strengths of radio signals received from wireless tags of sheets not being conveyed, determine a threshold value of signal strength for distinguishing a wireless tag being conveyed from wireless tags not being conveyed based on the first and second strengths, and control the roller to convey a second sheet with a second tag and control the reader/writer to write to the second tag when a strength of a radio signal from the second tag is greater than or equal to the threshold value.

According to one embodiment, there is provided an image forming apparatus including a conveyance unit, a detection unit, an image forming unit, and a control unit. The conveyance unit is configured to convey a print medium to which a wireless tag is attached and on which wireless tag position information indicating a position of the wireless tag is formed. The detection unit is configured to detect the wireless tag position information formed on the print medium. The image forming unit is configured to form an image on the print medium. The control unit is configured to control the conveyance unit and the image forming unit based on the wireless tag position information detected by the detection unit.

According to an embodiment, a stack-of-sheets package includes: a stack of sheets; a conductive sheet; and a package material. The stack of sheets is obtained by stacking printing sheets, each of the printing sheets having a printable surface and including a wireless tag. The conductive sheet is disposed at an end portion of the stack of sheets in a stacking direction of the printing sheets. The conductive sheet has a conductive region that overlaps with the wireless tag as viewed from the stacking direction. The package material packages the stack of sheets.
