Example Embodiment

[0022] A base net scribing and looping process for a seamed papermaking felt, comprising the steps of:

[0023] Step 1: Marking the line, you need to shape the base net on the setting machine for a circle, and after the base net shrinks and stabilizes, directly draw dotted lines on the setting machine to ensure the straightness of the line and ensure that the two lines are in the base net. Centerline of the fold in half. During the shaping process: the shaping temperature is 150 degrees, the shaping speed is 2M / min, and the shaping is done in one circle.

[0024] Step 2: draw yarn, operate strictly according to the reference line marked on the sizing machine, take out 3 weft yarns on this reference line to form a loop (because the reference line is not completely along the weft yarn, so cut the weft yarn at an appropriate distance, drawn strictly along the reference line).

[0025] Step 3: Form a loop. Fold the part of the base net from which 3 yarns have been taken out stri...

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...
