The object of the present invention is to provide a wet paper web transfer belt with excellent crack resistance in the regions of the wet paper web transfer belt facing the roll edges.This is achieved by an endless wet paper web transfer belt travelling by rotation while being supported by a plurality of rolls in the press part of a papermaking machine; wherein the wet paper web transfer belt has at least an outer circumferential resin layer on the wet paper supporting side, the outer circumferential resin layer comprises roll edge-facing regions positioned to face both edges in the width direction of at least one of the plurality of rolls and a central region positioned between the roll edge-facing regions, the difference in the thickness between the thickness of the roll edge-facing regions and the thickness of the central region is 0.5 mm or less, and the maximum profile valley depth Rv of the outer circumferential surface of the roll edge-facing regions is 40 μm or less.
摘要:
A conveying installation has least one endless conveyor belt guided via a plurality of rollers along a leading belt run for conveying material or products and a returning belt run, particularly for manufacturing a paper web with a wire belt or felt belt. At least one of the rollers has an adjustable mounting for adjusting and correcting a direction of movement of the conveyor belt. A tensioning unit for detecting and controlling a tension of the conveyor belt has a pressure-measuring apparatus disposed at the adjustable mounting. A movement correction unit for detecting deviations of a direction of movement of the conveyor belt from a correct movement and for correcting the movement includes a sensor that is disposed to monitor a lateral periphery of the conveyor belt. A sensor output of the sensor is used for adjusting the adjustable mounting of the one of the rollers.

The object of the present invention is to reduce the wear of the doctor blade applied to the wet paper web transfer belt and the wear of the guide rolls supporting the wet paper web transfer belt while maintaining the wear resistance of the wet paper web contacting surface and the machine contacting surface of the wet paper web transfer belt together with the adhesive and releasing properties of the wet paper web on the wet paper web contacting surface of conventional wet paper web transfer belts.This is achieved by a wet paper web transfer belt in which a polyurethane is integrated with a reinforcing base material comprising a wet paper web-side surface and a machine-side surface, at least the wet paper web-side surface of the reinforcing base material is embedded in the polyurethane, an outer circumferential layer comprising a wet paper web contacting surface is constituted by some of the polyurethane; wherein, at least the outer circumferential layer comprises a spherical filler.
摘要:
The present invention relates to a process of obtaining an industrial fabric with porous and controlled plasticized surface and an industrial fabric with the mentioned characteristics thereof. The invention also relates to an industrial fabric such as press fabric for use in the press section of a paper machine with enhanced aesthetic properties by the use of plasticizers and optional heat and/or pressure treatment.
摘要:
An industrial fabric such as an endless belt or sleeve for use in the production of nonwovens, and a method of making thereof are disclosed. The industrial fabric is produced by spirally winding strips of polymeric material, such as an industrial strapping or ribbon material, and joining the adjoining sides of the strips of material using ultrasonic welding or laser welding techniques. The fabric may then be perforated using a suitable technique to make it permeable to air and/or water.
摘要:
A method for detecting a target impact of the munition. The method including: providing the munition with a power supply having a piezoelectric material for generating power from an axial vibration induced by the munition; monitoring an output from the power supply; and determining if the munition has axially impacted a target based on the output.
摘要:
A fibrous structure includes first, second, and third relatively high density wet-formed discrete elements disposed in a repeating concentric pattern. Each relatively high density wet-formed discrete element is at least partially defined by a continuous relatively low density wet-formed network that extends about an area of the fibrous structure. The first, second, and third relatively high density wet-formed discrete elements are distinguishable one from another by their respective area dimensions.
