    In a grooved drum with a working drum surface of metal consisting of a cylindrical inner drum on which at least one ribbon is helically wound, turn by turn, the radially outer boundary of which forms the working drum surface, the ribbon also forming axially extending circumferential grooves, adjacent turns of the ribbon are connected to each other in a form locking manner on their sides facing each other in the axial direction causing the adjoining turns to be immovably fixed relative to each other so that in the event of a break in the ribbon the turns will not give in to the circumferential tension force generated during winding and burst open.

    (54) FURNISHED SHAFT BODY MACHINE
    The invention relates to paper making machines and can be used in the pulp and paper industry. The grooved shafts of paper machines are known; they are used for dewatering a paper web and containing a core and a shirt made of a profiled steel strip spirally wound on a core that forms a grooved surface of the shaft fl. After winding. Due to the different deformations of the upper and lower parts of the profiled strip, due to the difference in diameters, the upper part stretches more strongly during winding, which leads to uneven stresses inside the strip and its tilting during winding. The purpose of the invention is to increase the reliability of the shaft operation. The goal is achieved by the fact that the profiled strip of the shirt has a cross section, a part of which, extending towards the core, has the shape of a trapezium, facing a smaller base towards the core. FIG. 1 shows a general view of a grooved shaft; FIG. 2 - the cross-section of the profiled strip to 3 - the same, after winding; in fig. vivka. The grooved shaft contains a core 1 on which a profiled strip 2 is wound, having a cross section adjacent to the core 1 in the form of a trapezium, facing a smaller base towards the core. This is achieved due to the fact that one of the sides of the cross section is turned relative to the other side at an angle of sat., PS when winding such a strip on core 1, the side of the strip adjacent to the core is stretched due to the difference in the diameters of the outer and inner sides of the strip relative to the axis of the core less. In this case, the strip material is redistributed; it takes the correct rectangular shape, which excludes its tilting during winding and increases the reliability of the shaft operation. Grooved shafts are typically used in the press section of atelier paperwork to dewater the paper web.
