This invention relates to a method of controlling the operation of a winder in which method while forming at least one fiber web roll the fiber web is brought on the web roll via a nip formed by a first support drum and the web roll, which first support drum is driven by a first drive assembly (20) applying controllable torque to the drum and the winding force is applied to the web roll by a second drive assembly (22). In the method the second drive assembly (22) is controlled based on the indicative speed difference of the second drive assembly (22) and setting a friction coefficient for determination of maximum winding force.

In some embodiments, the instant invention provides an exemplary method for dispensing that at least includes: initiating a movement of a dispensing object along a dispensing passage of a dispensing device; determining, by a displacement sensor, a magnitude of a displacement of the dispensing object along the dispensing passage based on remotely measuring, by the displacement sensor, a characteristic associated with the dispensing object during the movement of the dispensing object along the dispensing passage; generating an indication by the displacement sensor when the magnitude of the displacement is equal to or exceeds a pre-determined distance value; separating, based on the indication, a portion from the dispensing object to form a remaining portion of the dispensing object and a separated portion of the dispensing object; and dispensing the separated portion of the dispensing object from the dispensing device.

A pinion gear is coaxially attached to vicinity of an end of an inner bar. The pinion gear is engaged with a rack gear and rotates in response to upward and downward movements of the tension bar. When the pinion rotates, the inner bar correspondingly rotates. The inner bar and an outer bar, which is a tension applying bar, are connected to each other so as to freely rotate. When the pinion rotates, the inner bar correspondingly rotates, while the outer bar remains unrotated.

An apparatus and method for producing self-adhesive labels, in particular in a self-service area, for example of a drug store, is provided. The apparatus comprises a dye-sublimation thermal printer, as a printing means for printing a printing pattern onto an adhesive film, and a cutting apparatus for cutting the adhesive film along a cutting pattern, the adhesive film being moved automatically from the printing means to the cutting apparatus. Initially, only a first moving unit of the printing means moves the adhesive film at a first speed to a second moving unit of the cutting apparatus, after which both moving units move the printed adhesive film further in the forward direction.
