A label winding device is for receiving a medium including a label liner and a label member that is removably attached to the label liner and has at least one label portion and a waste portion, separating the waste portion from the label liner at a waste separation portion, and winding the at least one label portion with the label liner. The label winding device includes: a waste winder for winding the separated waste portion; a label winder for winding the at least one label portion with the label liner without the separated waste portion; a waste guide for guiding the separated waste portion to the waste winder; a support for rotatably supporting the waste guide; a sensor for detecting a rotational speed of the waste guide; and a waste break detector for detecting break of the waste portion on a basis of the detection by the sensor.

A method, apparatus and program product may evaluate a packaging material to determine various metrics associated with the packaging material. A test apparatus may be used to evaluate packaging material using a take up drum capable of sensing containment force imparted upon the drum by packaging material applied thereto, and in some instances, simulated flaws may be formed in a web of packaging material to evaluate a packaging materials response to such flaws when under tension.

A computer program product, an industrial installation in particular a paper-making machine, an apparatus and method for predicting a position of a web break of a fibrous material web that has occurred or is imminent, wherein the method includes capturing parameters, in particular speeds of rollers for transporting the fibrous material web or a web tension thereof, where the parameters are advantageously stored in the form of time series, a self-learning algorithm is used to detect the imminent web break and to determine the position of the web break which is imminent and/or has occurred, where the basis for the detection or the determination is a deviation of the respective parameter, such as from a temporal mean of the respective parameter.

A method, apparatus and program product may evaluate a packaging material to determine various metrics associated with the packaging material. An apparatus may be used to sense flaws in packaging material, and in some instances, to accommodate such flaws by temporarily increasing a dispense rate of a packaging material dispenser.

A method for operating a machine for producing and/or processing a material web, wherein a first drive unit is supplied by a converter with a current, a vibration propagating over the material web is captured via the first drive unit, the vibration is measured and transformed into a measurement signal that is examined for presence of a signature that differs from the basic waveform of the current, a web tear is thus identified if the signature propagating over the material web is missing during the evaluation of the electrical measurement signal, whereby no further sensors, in particular optical sensors, are required to capture the measurement signal, and the measurement also occurs independently of a torque, a speed or speed development of drive motors over time and, moreover, the detection of the web tear does not require a comparison measurement at the machine without a continuous material web.

The present invention is directed to a method and apparatus for securely applying print to a web of continuous polymeric film. The web can first travel in a machine direction on a tensioning roller and onto a folding board whereupon the web is divided into first and second partial widths with a cross-section of the web taking on a U-shape or a V-shape. In between the cross-section of these two partial widths a printer can be placed such that the printer prints onto an inner surface of first partial width. Once the printing is complete, the folding of the web can be completed such that an inner surface of the second partial width is in contact with, covers, and protects the printed matter placed onto the first partial width.

A method for protecting a unit for converting a web substrate to limit a jam of the substrate inside the unit, the unit converting the substrate when the unit is stopped, in a packaging production machine: the steps of: detecting at the outlet of the unit that the converted web does not come out; stopping a motor of an infeed arrangement to prevent the substrate from entering the unit; stopping a motor of a feathering drive; and simultaneously stopping the machine, and guiding the substrate to an accumulation storage.

Proposed is an apparatus for supplying a roll-type material, the apparatus including an unwinder for unwinding a roll on which a material is wound, a rotation speed sensor for measuring a rotation speed of the roll, and a controller for performing a first deceleration for decelerating the rotation speed of the roll when the rotation speed of the roll is equal to or greater than a first reference rotation speed, and performing a second deceleration for decelerating the rotation speed of the roll when the rotation speed of the roll is equal to or greater than a second reference rotation speed after the rotation speed of the roll is decelerated. Accordingly, it is possible to adjust a supply speed of the material according to a remaining amount of the material without operator's control, and minimize waste of the material.

An apparatus and method for stretch wrapping of a palletized load uses film tension feedback derived from a film tension control load cell to control film dispensation. The load cell measures film tension and the film payout rates is determined by the film tension. Film tension values are used to determine when an out of bounds condition occurs, namely, when a film break has occurred, or when a possible film break is about to occur or when the film has been cut at the end of a wrapping cycle. To prevent film free end entanglement caused by a break, clamps engage the film so the film tail is controlled, eliminating the risk of recoil. The broken film tail may then be quickly and reliably reattached to the rotating load in a desired position.
