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.

According to an embodiment of the present disclosure, a roll-to-roll apparatus may include an unwinding unit, a winding unit, at least one supporting unit, at least one breakage sensor, and at least one holding unit. The at least one supporting unit is disposed between the unwinding unit and the winding unit, and supports the flexible substrate to move from the unwinding unit to the winding unit. The at least one breakage sensor may sense whether the flexible substrate is broken or not. The at least one holding unit may grip the flexible substrate while a breakage of the flexible substrate is sensed by the at least one breakage sensor.

A winding device includes a first roller that winds label roll paper that is composed with a continues base sheet, a plurality of labels and a marginal portion, a second roller that winds the marginal portion peeled off the label roll paper, a drive part that generates a driving force for the second roller to rotate, a drive transmission control part that is provided between the drive part and the second roller such that the driving force is transmitted to the second roller from the driving part, and stops transmitting the driving force to the second roller if a load placed on the second roller exceeds a prescribed load, a detection part that detects a rotation of the second roller, and a control part that determines a cutoff of the marginal portion based on the rotation of the second roller detected by the detection part.

A brake is provided for an idler roll (10) of a fiber web machine, in particular of a slitter-winder, which idler roll (10) has an outer shell surface (13). The brake (20) is located outside the outer shell surface (13) of the idler roll (10) in close vicinity of the idler roll (10) in a non-contacting position. The brake (20) has a permanent magnet (25), which is configured to be moved from non-braking position to a braking position and vice versa by an actuator or cylinder (35, 45).

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.

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, 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 of operating an off-line finishing device for fiber webs, in particular an off-line slitter-winder for winding fiber webs, wherein in operating the off-line device the running speed is automatically optimized to minimize cost of web breaks. The method considers the costs associated with a web break during unwinding in addition to the cost benefit of maximizing web unwind speed so as to maximize machine utilization. The method determines an optimal web break stopping time in a web break situation and how often a web break is predicted. Automatic optimization incorporates limitations including the maximum rotation speed of the parent roll, the maximum speed of the fiber web being unwound, the maximum positive torque which can be applied to the parent roll to accelerate the parent roll to a rotation rate which produces a desired web speed, and maximum braking torque.
