Scribing and Looping Process of Base Web for Seamed Papermaking Felt

Abstract

The invention discloses a base net marking ring-forming technique for a jointed papermaking carpet. The base net marking ring-forming technique comprises the following steps: (1) marking a line, sizing a base net on a shaping machine for one circle, and directly marking points and drawing two lines on the shaping machine after the base net is contracted and stabilized, wherein the two lines are straightly arranged and are located on an oppositely folded central line of the base net; (2) drawing yarns, operating according to a datum line marked on the shaping machine, and drawing three weft yarns from the datum line and using the yarns for forming a ring; (3) forming the ring, strictly oppositely folding a base net part with three drawn weft yarns, ensuring the upper and lower nets of the edges of the drawn yarns to be aligned, locating the ring in the middle of the base net, and keeping the upper and lower parts of the ring straight and un-inclined; (4) penetrating the ring, selecting a suitable wire size according to the width of the cloth and bringing the yarn with a 1.4mm diameter into the ring.

Description

technical field [0001] The invention relates to a base net scribing and looping process for papermaking felts, in particular to a base netting and looping process for seamed papermaking felts. Background technique [0002] With the support of the state and related policies, my country's papermaking industry has developed rapidly in recent years. At the same time, papermaking machinery and equipment are developing in the direction of large-scale and high-speed development. Certain achievements and better development, but due to problems in industrial policy, technology research and development, capital, talents, etc., the scale of mass production of high-end papermaking felts has not yet been formed, and the quality of felts and the demand for high-speed large-scale paper machines still exist There must be a gap. How my country's papermaking felt industry creates a high-end brand of domestic papermaking felts, further enhances market competitiveness, gradually realizes the loc...
