A plurality of marks (11) equidistantly provided on both side edge parts (1a) of a long medium (1), a plurality of first indicator holes (12) equidistantly given on at least one of the side edge parts (1a), and a plurality of second indicator holes (13) given on at least one of the side edge parts (1a) on a straight line different from a row of the first indicator holes (12) at spacings shorter than spacings of the first indicator holes (12) are provided, and the second indicator holes (13) are each provided to a side of a trailing-end mark (11b), and each gradually comes closer to a leading-end mark (11a) as the long medium (1) runs toward a trailing end.

A material tracking system is provided for tracking material stored on and drawn from a reel. The material tracking system may include a reel, detection element, digital logic components, battery and power components, transceiver and communication components, location receiver, enclosure, analytic component and interface component. One or more sensors relative to the reel may detect a position indicative of forward or reverse reel rotation. A processor may analyze signals to count rotations of the reel, which is savable in memory. A battery may provide power. The system may also record the time and location associated with rotations. A method to operate a tracking material stored on and drawn from a reel using the material tracking system is also provided.

A system and method for tracking the remaining length of a material wound on a reel is disclosed. In the system, two sensors deployed relative to the reel (and each other) produce a detection signals when a detection element mounted on the reel is near the respective sensor in an order indicative of forward or reverse reel rotation. The system further includes a processor operably receiving the detection signals to count a total number of forward rotations of the reel, which count is saved in memory. A battery powers the processor, memory, and sensors. The system further includes a transceiver that removably and operably couples between the memory and a calculator that calculates the remaining length of the material wound on the reel based on the total number of forward rotations of the reel. The system may also record the time and location associated with the rotations.

Medicine packaging apparatuses and methods for accurately determining a remaining sheet amount of a medicine packaging sheet are described. The apparatus includes: a roll support section to which a core tube of a medicine packaging sheet roll is attached; a sensor disposed in the roll support section for outputting a count value according to a rotation amount; a wireless reader-writer unit for writing information to a core tube IC tag and reading said information; an information generation section for generating information to be written to the core tube IC tag; a remaining sheet amount estimation section for estimating a current amount of remaining sheet based on the information and dimensional information of the core tube; and a controller which selectively performs an operation if a reference time-point count value is not yet written to the core tube IC tag and another operation if the count value is already written thereto.

The invention relates to a method for a multitrack provision of web-like interleaved sheet material at a cutting region in which products supplied on multiple tracks are cut into slices and interleaved sheets are introduced which are cut off from the provided interleaved sheet material in the cutting region and for which a normal length is predefined which is dependent on the respective application, in which material webs are removed from at least two material stores which are each associated with one or more tracks; and in which the material consumption of at least one material store is impacted during operation, in particular in dependence on residual quantities in the material stores, in that the length of the interleaved sheets is varied in the respective track or tracks with respect to the normal length at least for this material store.

A converting line for coreless roll products includes a rewinding machine and a controller. A log of convolutely wound web material is wound in the rewinding machine during a wind cycle. A diameter of the log, a caliper of the web material, and an amount of tension of the web is determined at a plurality of time points during a time period of the winding cycle. The controller is enabled to generate a signal to change an operating condition of the converting line based upon at least one of a diameter determination at a time point during the wind cycle, a caliper determination at a time point during the wind cycle, a wound web amount determination at a time point during the wind cycle, and a tension determination at a time point during the wind cycle.
