experiment example 1

[0084] Prepare figure 1 , figure 2 The shown is a pressing and crimping device for acetate fiber bundles for cigarette filters. In the pressing and crimping device for fiber bundles, the width of the pressing roller is 19mm, and the material of the tow width limiting part is chrome sprayed on the surface. Finished SUS440C stainless steel, tow protruding prevention plate is made of alumina ceramics. As shown in Table 1, the distance B between the width A of the first and second press-in rollers and the wall surface of the left and right pair of tow sticking prevention platens having the tow width restricting portion and the tow sticking out preventing portion The difference (A-B) is set to 5 types of 0.4mm, 1mm, 5mm, 10mm, and 15mm, and the distance C between the front end of the tow width restricting part and the nip of the press-in roller is calculated for each tow width restricting part and the yarn The difference in distance B (A-B) between the walls of the pressure plat...

[0091] Prepare figure 1 , figure 2 The press-fitting and crimping device for acetate fiber bundles for cigarette filters is shown. In the press-fitting and crimping device for fiber bundles, the width of the press-fitting roller is 19mm, and the material of the tow width limiting part is chrome sprayed on the surface. Finished SUS440C stainless steel, and the material of the pressure plate for preventing the tow from sticking out is alumina ceramics. As shown in Table 2, the distance B between the width A of the first and second press-in rollers and the wall surface of the left and right pair of tow sticking prevention platens having the tow width restricting portion and the tow sticking out preventing portion The difference (A-B) is set to 1.6 mm, and the distance C between the front end of the tow width restricting part and the nip of the press-in roller is set to three types of tow width restricting parts (there are tow width restricting parts) ), the operation was conti...

Abstract

According to the present invention, a tow-width restrictor (10a), constructed from a plate material shaped substantially as an isosceles triangle having an acute angle at the front tip with respect to the direction of travel, is disposed in the tow introduction part (10) of a pair of fiber-tow push-in rolls further upstream from the nip point (9) of push-in rolls (1, 2). A tow protrusion preventer (11a) for preventing fiber protrusion in the fiber tow (8) is disposed subsequent to the tow-width restrictor (10a) in a roll side surface that includes the nip point (9) of the pair of the push-in rolls (1, 2). The difference between the push-in roll width (A) and the distance (B) between the inner wall surfaces of a pair of protrusion prevention holding plates (15) is 0.2-12 mm. The distance (C) between the tip of the tow-width restrictor (10a) and the nip point (9) of the push-in rolls (1, 2) is 0-22 mm.

Description

technical field [0001] The present invention relates to a press crimping device for crimping a fiber bundle and a method for manufacturing a fiber bundle. A crimping device for continuously and efficiently producing crimped fiber bundles without damage, and a continuous manufacturing method for crimped fiber bundles. Background technique [0002] As a method of crimping a fiber bundle, a crimping device using a press-in roller is widely used, and the crimping device using the press-in roller produces a crimped fiber bundle by passing a pair of press-in rollers and pressing the fiber bundle into a crimping chamber. In order to make a crimped fiber bundle with this device, the fiber bundle needs to be held by the press-in rollers at a predetermined holding pressure, and the fiber bundle held by the pair of press-in rollers will spread to both sides between the press-in rollers. In order to prevent the stretching of the fiber bundles that will protrude from the left and right ...
