An unwinding system includes a detector assembly configured to detect a position of a fiber unwound from a bobbin and the presence of fuzz. The system further includes a controller configured to adjust at least one of a lateral position or a rotational speed of the bobbin based on at least one of the position of the fiber tow or the presence of fuzz.

A method, apparatus and program product may utilize packaging material quality compensation to sense changes in certain characteristics of a packaging material that can be associated with increased risks of film breaks, and automatically make certain changes in machine settings to mitigate the impact of those enhanced risks.

An example method comprises operating a drive unit to advance a substrate in a substrate advance direction toward a printing station. At the printing station, a first line is printed onto the substrate. A drive unit is instructed to advance the substrate in the substrate advance direction by a target amount, and a second line is printed onto the substrate. The distance between the first and second lines in a direction perpendicular to the substrate advance direction is calculated and, based on the calculated difference, a tension of the substrate is modified.

Provided in a paper sheet feeding apparatus and a box making machine are: a plurality of wheels capable of supplying a sheet by coming into contact with a lower surface of the sheet; a grate liftable and lowerable to an ascending position positioned above upper edges of the plurality of wheels and a descending position positioned below the upper edges of the plurality of wheels; a drive motor; an elevating device capable of lifting the grate to the ascending position by rotating the drive motor in one direction and capable of lowering the grate to the descending position by rotating the drive motor in the other direction; and a control device capable of adjusting an amount by which the grate is lifted and lowered by the elevating device by controlling the drive motor.

The present invention provides an apparatus for recycling artificial or synthetic layered materials. The apparatus includes a first conveying section arranged to receive and unroll a used or pre-processed roll of artificial or synthetic layered material, in use, and at least a second conveying section arranged to receive and re-roll the subsequently processed roll of said material. The apparatus further includes a beating section located intermediate said first and second conveying sections, arranged to beat and/or agitate said unrolled material as it is moved from the first conveying section to the at least second conveying section, in use.

A transport device includes a transport belt configured to alternately repeat a transport operation of transporting a medium and a non-transport operation of not transporting the medium, a detection mechanism configured to detect a movement amount of the transport belt in the transport operation, and a control section configured to determine a magnitude of tension of the transport belt based on a vibration state of the transport belt when the transport operation ends, the vibration state being detected by the detection mechanism.

The present invention provides an adaptive control system to control a plant using direct output feedback in which a function of the full plant state, as opposed to estimates thereof, is used for feedback control of the plant. The adaptive control system of this invention is therefore highly useful in the control of plants, particularly plants for controlling the physical properties of rolls of web material and more particularly a calendering apparatus. Accordingly, in a particularly preferred embodiment the adaptive control system of this invention controls loading of a calender apparatus, such as a pair of opposed rolls forming a calendering stack, based upon the physical properties of a previously processed web.

A printing system includes a printing unit, a determination unit, and a switching unit. The printing unit prints an image on a recording medium. The determination unit compares a prestored reference image and a read image corresponding to a reading result of a printed document in which the image is printed on the recording medium and determines whether a result of the comparison satisfies a predetermined condition. The switching unit switches a discharge destination of the recording medium based on a result of the determination. The switching unit switches a conveyance path of the recording medium based on whether the determination is performed.
