Water streak roller and method of manufacture

Abstract

The invention relates to a lay mark roller for manufacturing lay mark paper and a manufacturing method thereof. The lay mark roller comprises a plurality of circular-ring shaped framework plates, a fixed drawing wire for connecting the circular-ring shaped framework plates into a hollow roller cylinder, a roller tray and a roller shaft. The lay mark roller is characterized in that the radial surface of the inner side on the periphery of the framework plate is provided with a plurality of through holes evenly, the circular surface is respectively provided with grooves in radial communicated with the through holes, a plurality of metal wires are passed through the through hole corresponding to each framework plate, the two ends of the tensioned metal wire are fixed inside a holddown groove on the roller tray, the two ends of the drawing wire are fixed and are connected with the roller tray. In the invention, the framework plates and the metal wires are not welded together, the frameworkplates are not deformed, the metal wires have uniform tensity, thereby forming flat and straight staggered lines on the web paper page; the smooth appearance of the metal wire and the arrangement of the radial groove on the framework plates form natural and smooth lines with good third-dimensional effect; the paper fiber is not scraped and the piling paper pulp is not caused in use, the manufacturing method is simple and convenient, the technique is reasonable, the manufacturing cycle is short, the post processes of lathing and grinding are omitted and the production cost is lowered.

Description

technical field [0001] The invention relates to a paper making equipment, in particular to a watermark roller for producing watermark paper and a manufacturing method thereof. Background technique [0002] We know that the water pattern paper uses the water pattern roller to displace the fibers of the wet paper sheet in the wire part of the paper machine, and embosses the vertical and horizontal lines on the periphery of the water pattern roller on the wet paper sheet to form a vertical and horizontal cross, different transparency, three-dimensional Special paper that is visually appealing, visible when viewed flat, neatly arranged, and evenly textured. At present, the water pattern paper on the market is mainly imported from abroad. The fundamental reason is that there is no special water pattern roller for the production of water pattern paper in China. The applicant manufactured the first watermark roller in China based on the structure of the watermark roller currently ...

Problems solved by technology

[0003] In order to overcome the stress and deformation caused by welding between the ring-shaped skeleton piece and the axial metal strip in the prior art, resulting in poor straightness of the pattern of the water pattern paper, lack of three-dimensional effect of the paper pattern, uneven texture, and thick paper It is easy to break at the water lines, and the axial metal strip is easy to scrape the paper fibers in the pulp when used, which makes the paper flatness poor, causes waste of pulp and is not easy to clean, and has the disadvantages of complicated manufacturing process, long cycle and high cost. The invention provides a watermark roller and its manufacturing method
