    摘要: In a wet press for dewatering a web of material, for instance a web of paper, a contact pressure device presses against a rotating roll and exerts a pressure which increases in the travel direction of the web of paper. For this purpose, several rows of contact pressure elements are arranged sequentially in the travel direction of the web of paper. In each row the contact pressure elements are arranged side by side transversely to the travel direction of the web of paper. In order to circumvent a differential dewatering at the location of the contact pressure elements and at the gaps between the contact pressure elements of a row, the contact pressure elements of successive rows are shifted or staggered in relation to one another transversely to the web of material such that they mutually overlap. This prevents the arisal of strips in the paper being processed.

    摘要: The separator of the machine is constructed to retain the paper web on the inner (upper) wire upon separation of the two wires. To this end, the separator positions the roll for the outer (lower) wire downstream of the point of separation of the two wires. A suction box can be used in the separator roll to assist in retaining the paper web on the inner wire (FIG. 1). The inner wire extends from the separator along a straight run which defines an angle of less than 90.degree. relative to the straight path traversed by the two wires upstream of the separator.

    摘要: A wire is passed over the suction breast roll between the formed paper web and the doffer belt or the previously formed paper webs and doffer belt. The doffer felt is disposed in an unencumbered fashion over each of a plurality of consecutive suction breast rolls. The wire is removed from the web at a downstream point outside the dewatering influence of each breast roll. Stripping of the wire from the paper web is aided by various suction devices or couch rolls at this latter point.

    摘要: The present invention is directed to a heated sag-compensation roller, with short heat-up and cool-down times and a more even temperature distribution, which reduces the risk of damage to the roller shell. These improvement are achieved by the roller shell being heated or cooled from the inside and the outside simultaneously. The heating devices can be controlled so that the temperature difference between the inside and outside does not exceed a particular value.

    摘要: An arrangement containing a controlled deflection roll which is supported by means of support or pressure elements against a roll support or beam. There is also provided a regulation arrangement for regulating the position of the roll shell, wherein the position of the roll shell at least at both of its opposed ends is detected by position sensors or feelers and deviations from a set or reference value are processed into two adjustment or positioning magnitudes which act upon the support or pressure elements. Both of the adjustment magnitudes are formed while taking into account a possible difference between both of the reference value-actual value differences and thereafter weighted and grouped together with further adjustment magnitudes and inputted to the support or pressure elements.

    摘要: A winder for a papermaking machine comprising a cylinder over which there is guided the paper web which is to be wound-up. A reel-spool receives the wound-up paper roll or package and a contact or press device presses the reel-spool in the direction of the cylinder. An endless band arrangement is guided such that it extends over the cylinder between its surface and the paper web, the band arrangement in conjunction with the paper web being wrapped about part of the circumference or outer surface of the cylinder and extends between the cylinder and the reel-spool or, as the case may be, the paper roll or package wound upon the reel-spool. The band arrangement also encloses the paper roll or the reel-spool along part of its circumference.

    摘要: A controlled-deflection roll having a stationary roll support or carrier and a tubular roll shell rotatable about the stationary roll support. The tubular roll shell bears upon the roll support or carrier through the intermediary of at least one bearing or support element. The roll shell is provided at its ends with guide members which are rotatably mounted in the roll shell and which are guided on the roll support in the direction of the pressing or contact movement or the disengaging or lift-off movement of the roll shell. The controlled-deflection roll is provided with a scraper device equipped with a scraper blade which, during operation, is in contact with the surface of the roll shell, and the scraper device is secured to the guide members.
