Abstract

PURPOSE:To effectively utilize all the raw cloth by conveying and processing the belt-like raw cloth woven with a curved line attached on one side, winding the inside end of this raw cloth around an erected rotary shaft and stacking it in sequence, and tightening the top and bottom of the stacked one with a flange to form a desired roll. CONSTITUTION:The belt-like raw cloth 1 woven with a curved line attached on one side is conveyed by rollers 2 in accordance with a bending habit, the belt- like raw cloth 1 is coated and impregnated with a heat-resisting liquid during this conveying process using a coating roller 5 and a pinching roller 6, then the inside end of this raw cloth 1 is wound around an erected rotary shaft 7 and is stacked in sequence. This stacked raw cloth 1 if kept in a tightened condition from above and below by a flange screwed with both ends of the rotary shaft 7, thus a roll is obtained effectively utilizing all the raw cloth 1.

Description

[Detailed description of the invention] The present invention relates to a method for producing seed rolls inexpensively and easily.

Conventionally, for example, it was used as a grinding and polishing roll.
2 1 3 4, Publication No. 6, Special Publication No. 50-39590
As shown in the publication, a flat material that has been subjected to necessary treatments such as adhesion of abrasive grains is punched out into a disc shape of the required diameter, and at the same time, a shaft insertion hole is punched in the center of the material, and the hole is superimposed into the shaft. It is available that is pressurized and tightened with a flange.

That is, as shown in Figure 4, a flat plate-shaped material is punched out into a disk shape, and at the same time a shaft insertion hole (2J
), but it required a lot of punching work and had the disadvantage that the hatched area in the figure was wasted and was extremely uneconomical.

The present invention eliminates the above-mentioned drawbacks, and aims to manufacture various rolls by effectively utilizing all of the accumulated time.

An embodiment of the present invention will be described in detail below with reference to the drawings.

In the present invention, first, as shown in the first figure, a belt-shaped raw fabric (1) is prepared which is knitted with a curved tendency so as to curve to one side. The belt-shaped original fabric (1) is not limited to a single sheet, and may be woven into a cylindrical (tubular) shape.

The strip-shaped raw fabric (1) has a relatively thick weft yarn (lα) provided in the width direction, a somewhat thin warp yarn (1b) provided in the length direction, and has a relatively coarse mesh without being densely knitted, The structure is such that heat-resistant resin, resin mixed with abrasive grains, etc. can easily penetrate into the inside of the mesh. Furthermore, by making the weave coarser, it is easier to knit with a curved pattern.

Further, the weft (1a) and the warp (1b) may be made of natural fibers, chemical fibers, minerals, or a mixture thereof, depending on the purpose, and may be a single thread or a twisted thread.

Figure 2 shows an example of manufacturing a heat-resistant roll for conveying a heated steel plate using the strip-shaped original fabric (1).

Naturally, the weft (]a) and the warp (1b) constituting the belt-like raw fabric (1) are heat-resistant, that is, fibers used in flame-resistant 4-heat clothing, such as Pike (trade name = (manufactured by Toho Rayon), Keffler (trade name - DuPont), etc. are used.

In FIG. 2, first the strip-shaped original fabric (1) is conveyed;
This is done using a roller (2) adapted to the curvature of the belt-shaped original fabric (1) or an appropriate kite plate (not shown) so as not to correct the curvature of the strip-shaped original fabric (1).

In the process of conveying the strip-shaped raw fabric (1), the coating roller (5
) and clamping rollers (6) to coat and impregnate the strip-shaped raw fabric (1) with the heat-resistant liquid.

Note that as the heat-resistant liquid, for example, an inorganic compound such as ceramic titanium is used.

Furthermore, an upright rotating shaft (7) is provided in front of the conveyance path of the strip-shaped raw fabric (1), and the rotating shaft (7)
) and the inner end of the strip-shaped original fabric (1) is wrapped around the material and polymerized in sequence.

That is, the rotating shaft (7) is supported on a vertically movable turntable (8), and as the inner end of the strip-shaped raw fabric (1) is wrapped and superposed, the turntable (
8) is lowered little by little until the polymerized strip-shaped raw fabric (1
) Turn tape/L so that the upper surface of the strip (1) always remains in a horizontal position with the conveyance path of the belt-shaped original fabric (1).

(8) is controlled.

In addition, in the case of the drawing example, the above-mentioned rotating shaft f7) I
c 6 A key (7a) is configured in advance, and a key (7a) of the belt-shaped raw fabric (1) (in the general feed path) is set to fit the key (7a) of the rotating shaft (7). Groove (9)
A punching device flO) is provided.

Therefore, during polymerization, the band-shaped raw fabric (1) is wrapped around the rotating shaft (7) by wrapping the belt-shaped raw fabric (1) in a roll-like manner.
1) is integrated, and the rotary shaft (7) can be used in any device that requires it.

Next, when the above-mentioned winding is completed, the press plate (
Lower the mark and pressurize the entire area or heat and press as necessary.

Then from both ends of the rotating shaft (7) flanges (12)
It is only necessary to tighten and hold the belt-shaped original fabric 71) which is wrapped around the rotating shaft (7) by screwing the two together and wrapping it in a superimposed manner.

As mentioned above, the present invention has a curve on one side.
The JWl woven belt-shaped raw fabric (1) is generally fed once, and the belt-shaped raw fabric (1) is
1) is subjected to the necessary treatment, and then the inner end is wrapped around the rotating shaft that is made to stand upright, and the 11r polymerization is carried out, and the upper and lower parts are tightened with flanges. There is no need to punch out the material into a disk shape of the required diameter and at the same time punch a shaft insertion hole in the center, so there is no waste due to punching, and an extremely economical effect can be obtained. .

In addition, when constructing a grinding and polishing roll according to the present invention, a mixed liquid of abrasive grains, a thermosetting resin, etc. is coated and impregnated onto the strip-shaped raw fabric instead of the heat-resistant liquid.
