Abstract: Process for the manufacture of stretch resistant, liquid impermeable, flexible press bands, in particular for dewatering presses of paper-making machines.

Abstract: The invention relates to a method of the manufacture of dimensionally stable, liquid-impermeable, flexible press bands, particularly for wet presses of paper making machines. With known manufacturing methods for such press bands, the provision of a structured surface for liquid discharge on the outer surface of the press band, which faces the fibrous web or the felts, is achieved either by reversing the press band after removal from the casting mould so that the structured surface becomes the outer surface of the band while the smooth surface forms the inside thereof, or by grinding drainage ducts into the outer surface of the press band. But especially in the case of small band diameters, reversing of such cast press bands causes serious problems and entails considerable expenditure, wherein the risk of damage to the band cannot be excluded and grinding of the drainage ducts is just as expensive.

Abstract: The production of tension-proof, liquid impermeable, flexible bands which are preferably utilized for presses to dewater fiber material webs and are subjected therein to substantial tensile stresses between a press-shoe and a press-roll as the same glide across the press-shoe which is effected by means of penetration of a flowable mixture of a prepolymer with a cross linking agent onto the reinforcing band, preferably formed of fabric and receiving the tension forces in a direction longitudinally of the press band. Penetration most effectively occurs through covering the fabric band by pouring thereover of the flowable mixture as the band is in stretched condition and is moved.

Abstract: The invention is directed to a composite-type paper making wire or screen, comprising an upper or forming fabric and a lower or wear fabric including at least three sets of longitudinal threads and at least two sets of cross threads. Due to the imperfect nature of the paper-facing surface which results in all kinds of markings in the paper, paper making screens of this type are unsuited for the manufacture of fine papers. To eliminate this drawback, the screen is formed in such a way that at least half of all outwardly disposed longitudinal knuckles of the upper fabric (paper-facing side) of the screen are formed of two sets of longitudinal threads and that the first set of longitudinal threads is woven with the first set of cross threads, the third set of longitudinal threads is woven with the second set of cross threads, and at least portions of the second set of longitudinal threads are woven with both sets of cross threads.

Abstract: A loom wherein several gripper shuttles advance simultaneously along an endless path has a track with an arcuate section extending along an arc of 180 degrees ahead of the inlet to the shed. Shuttles are temporarily stored in a magazine ahead of the arcuate section and are propelled into the arcuate section and into the range of an accelerating conveyor in synchronism with movements of the reed toward and away from the fabric. The accelerating conveyor is driven by a variable-speed motor to advance a freshly engaged shuttle first at a low speed and to thereupon accelerate the shuttle to a maximum speed not later than on entry of the shuttle into the open shed. The shuttles have guide rails, guide faces and/or guide rollers which cooperate with complementary guide elements of the reed to prevent the ejection of shuttles during travel through the shed.

Abstract: Device for spraying a traveling paper web or the like with a liquid under the influence of an electrostatic high voltage includes spray nozzle means for spraying the liquid through a given space and onto the web, high voltage source means, electrode means connected to the high voltage source means and energizable thereby to ionize the space through which the liquid is sprayed, and means for grounding the web and the spray nozzle means.
