    Curved roll with rubber sleeve, type W. G.


    In the textile, foil and plastic industry the roll serves to keep the width of heavy webs stretched. The roll stretches the base material in lining and coating processes. In the paper and paper processing industry it stretches the width of paper in calenders, flexographic and gravure printing processes, in slitting and cross cutting machines, coating machines, etc.
    Maximum web speed up to 500 m/min. Special design for higher speeds upon request.
    This roll is suitable for keeping the width of paper free of creases during the operation. it guides wires as well as felts of the paper machine in wet or dry operations. The roll regulates the wet felt and helps to achieve a better drainage, thus prolonging the operational life considerably. It serves to maintain the width of paper in front of the pope-roller, in calenders, coating and pasting machinery, etc. Suitable up to a maximum web speed of 1400 m/min.

    Drive of a bowed roller directly fixed on a special mounting, designed on customer's specification.

    Heavy construction curved roll
    for application in the paper industry

    Field of application:
    Wire part in wet operations, felt straightening rolls, wires in dryer section, smoothing units, pope rollers, calenders, reel slitter rewinders, coating and pasting machines.
    A new end packing with oil chamber system has been developed especially for completely wet operations. The radial packing runs over molybdenum-coated friction rings which guarantees utmost packing and long operational lie. Re-lubrication from the side of the roll axle.

    Axlediameter 150mm
    Roller face 7500mm,
    with V-belt drive pulley.
    Roller is running in a slitter.

    Curved rolls with steel sleeve, type W. S.

    Suitable for application in the paper industry. The roll keeps the paper stretched in front of the slitter-rewinder and separates the reels after cutting. In calenders and in front of the pope-roller it keeps the web free from creases. Very good results are obtained in the drying tunnel at high temperatures. The roll is furthermore used in paper processing, in slitting and cross cutting and in printing machines.
    Maximum web speed up to 2500 m/min.

    The adjustable bow combined with a turning range of 360¡Æ by means of a turning gear allows maximum adjustment of these rolls. This can be effected during operation by a slight turn of the adjusting screw. The height of the bow remains in the adjusted position without any additional lock. The advantages of this roll become obvious when handling different materials or in continually changing processes.
    Especially behind the size press where due to the wet condition the width of paper tends to crease very much. The application of this adjustable roll has proved very useful.
    Very good results can also be obtained with this roll in foil processing since this material allows more or less stretching depending on its quality.

    Einbau und Projektierung

    In order to achieve an optimum spreading effect the following points should be observed.

    The wrap angle "W" should be noted when planning the installation:

    For paper and foils 20¡Æ - 40¡Æ
    For metal wires 15¡Æ - 20¡Æ
    For plastic wires 20¡Æ - 40¡Æ
    For wet felts 30¡Æ - 60¡Æ

    The web feed has to be effected always from the concave side of the roll.
    In order to avoid irregular wear the spreading roll must be mounted horizontally and at right angles to the web path.
    The distance "E" between the spreading and the following roll should not be too large. It should not exceed 2 or 3 diameters of the roll.

    The distance "A" may be larger, but it should not exceed twice the distance "E".


    Adjustment
    At normal tension and web conditions the posting of the
    curved roll is as shown. This position is the best in order
    to avoid irregular wear, especially when using rolls with
    rubber sleeves.

    When webs with slack edges are handled the axle it
    turned form ¡±normal¡± to ¡±concave¡± until the proper tension
    of the edges is achieved and the center part of the web
    becomes slack.

    If the center part of the web is slack the axle is turned
    form ¡±normal¡± to ¡±convex¡± until the proper tension of the
    web center is obtained.

    All these adjustments can be effected and registered by
    means of a scale on the swivel gear.


    Maintenance
    Where necessary, the rolls will be accompanied by
    corresponding maintenance instructions.
    The operational life is almost unlimited. Should the roll,
    however, become defective by extreme wear it can rapidly
    be repaired in our factory.
