  • Patent number: 6843445
    Abstract: The invention relates to a roll stand (1) for a continuous unrolling of several rolls (8, 8?) of reeled, web-like material, which are unrolled consecutively after each other in the roll stand, and which rolls are arranged to be changed by roll changing from an almost depleted roll (8?) to a new, full roll (8) in said roll stand, which roll stand comprises a machine stand (2) with two gable sides (3, 4), which are arranged aloof from each other, a horizontally arranged hub girder (9) which is rotatably journalled at the gable sides and around which hub girder the rolls are arranged to be pivoted between an inlet side (6), to which new, full rolls (8) are delivered, and an outlet side (7) from which the web-like material is unrolled, at least two roll holders (10, 10?) which are arranged at the hub girder for handling of each roll and which roll holders each comprises two roll holding arms (11) which are mounted linearly displaceable laterally along one or several, axially along the hub girder and rigidity moun

  • Publication number: 20020066173
    Abstract: The present invention provides a method for producing a bending-resistant, elongated body, preferably a shaft or beam. The invention is characterized in that an elongated blank is produced having at least one cavity extending essentially along the entire length of the blank, the inner surface of which cavity is at a distance from the mass center of the blank seen in a section at right angles to its longitudinal axis and that affixed in the cavity is a fiber composite body with an outer surface essentially congruent with the inner surface of the cavity and that majority of the fibers in the fiber composite body both extend essentially parallel to the longitudinal axis of the elongated blank and are elongated along the whole of its length. The invention also relates to an arrangement produced according to the method.

  • Patent number: 5282583
    Abstract: A roll stand is designed to unwind a material web (60) to a printing machine (2) or other production machine from an unwinding roll (13) in the roll stand and for a stoppage-free automatic shifting to a new roll (5), when the unwinding roll has been emptied to the desired degree. In accordance with the invention, tension is detected in the material web, which while braked in the roll stand is fed into the production machine. Based on that detection, the power supplied to or from a power receiving or power supplying system is regulated in such a way that the tension in the material web, which is fed in to the production machine, is kept constant.
