CONSTITUTION:An apparatus, consisting of a web stripping roll 3 covered with a metal card clothing 2 having 25-60 deg. working angle (alpha) of teeth 1 arranged in the vicinity of a doffer 4 covered with a metal card clothing 41 having 45-65 deg. working angle of teeth at 0.1-0.5mm. interval (C1) therefrom and a web receiving and delivery roll 7 covered with a metal card clothing 6 having 25-60 deg. working angle (alpha) of teeth 5 at or below the center of the web stripping roll 3 and within the radius thereof at 0.1-0.8mm. interval (C2) from the web stripping roll 3. The surface speed ratio between the doffer 4 and the web stripping roll 3 is 1:(1.02-2.0), and the surface speed ratio between the web stripping roll 3 and the web receiving and delivery roll 7 is 1:(1.02-1.5).

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a web stripping device for a carding machine that completely strips the web on a dot in a carding machine such as a flat card or a roller card.

Conventionally, as a device for completely stripping the web on a dot in a carding machine, a stripping device has been proposed in which a roller having a serrated tooth is entirely disposed and a wire is temporarily placed thereon. However, when the above-mentioned conventionally known web stripping device is used in a carding machine used for manufacturing cotton or nonwoven fabrics such as cards for cotton manufacturing or nonwoven fabric manufacturing cards, the carding machine is exposed to extremely harsh environments. Since the spinning machine is operated under such conditions, there are disadvantages in that the web wraps around the peeling roller and spinning cannot be performed, or the web cannot be reliably peeled off from the dot.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and provides a web stripping device t that can reliably strip the web even under adverse conditions in the spinning environment.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

As shown in FIG. 1, a web peeling roller 3 on which is temporarily placed a metal cloth 2 having teeth 1 having an angle α of 25° to 60°, and a metal needle having an angle α of 45° to 65°. The cloth 41 is wrapped around the cloth 41 and the cloth 41 is placed close to the cloth 41 with an interval C1 of 0.1% to 0.5X.

A metal cloth 6 having teeth 5 having a plow angle α of 25° to 600 degrees so as to be close to the axis of the web peeling roller 3 or below the axis and within the radius of the peeling roller 6.
A web delivery La-57w coated with is placed. In addition,
The distance c2 between the web peeling roller 6 and the web delivery roller 7 is set to 0.1 to 0.8%.

The web 11 arranged as described above has a high surface speed of 1.02 to 2.0 when the web [I roller 6 has a surface speed of 1.02 to 2.0], When the web transfer roller 7 is rotated in the same direction as the arrow A) (arrow B) and the surface speed of the web peeling roller 3 is 1, the web peeling roller is rotated at a high surface speed of 1.02 to 1.5. 3 in the same direction (arrow C).

By the way, the tooth shape of the metal clothing temporarily stacked around the web peeling roller 6 and the web delivery roller 7 is 6th.
As shown in Figure (A), the back side of m 1 (5) is completely vertical, and as shown in Figure 5 (B), m 1 (5)
) with an acute angle on the back side is best for use.

The metal clothing for the material, the web peeling roller 3, and the web delivery roller rough can be of the same tooth shape or of irregular tooth shapes, and can be used in appropriate combinations.

Specific example: A metal needle having a cross angle α of 300 violets, a number of ridges of 25.4% of the length; a per 10i11, and an edge thickness H of 1.3'X, as shown in Fig. 2. The distance C1 is set to 025 for all web peeling rollers 6 covered with cloth 4.
z, and is covered with a metal clothing 6 having the same specifications as the metal clothing 2 described above. , are arranged in close proximity to the web peeling roller 3 below its axis, with an interval C2 of 0.5%.

Then, the web peeling roller 3 rotates at a surface speed that is 1.15 times that of the docker 40, when the total surface speed of the web peeling roller 3 is 1. , it rotates at a surface speed 1.26 times faster than that of .

When the web stripping device configured as described above was attached to a full cotton card and a compound 'ft4 that did not generate static electricity was spun, the web was reliably stripped from the dot, and the web stripping device was placed close to the web stripping device. transferred onto the conveyor. Furthermore, similar results to those described above were obtained when natural fibers were spun.

As configured above, the web peeling device of the present invention uses metal cloth for both the web peeling roller and the web delivery roller, so it can be used for applications such as cotton cards and cards for nonwoven fabric manufacturing, especially under severe spinning conditions. When used in a carding machine to spin either natural fibers or synthetic fibers, the entire web can be reliably peeled off, and the web can also be reliably received and transferred.

For this reason, a high-speed carding machine was created that enabled the carding machine to speed up.
Moreover, since there is no web wrapping, handling is easy and productivity can be greatly improved.
