Abstract

A kind of jointing method is used for the technical fabric, the particularly joint of the belt conveyor of corrugated board milling train of paper machine or similar machine.Its adjacent layer (17,18,24) inwardly is cut into complementary ladder-type structure with the end (12,13) of the connected multiply cloth of fixed line, in the plane of its step between two adjacent tissue layer (17,18).Between the tissue layer of each relative fabric ends, be provided with a seam clip (14) that is lower than plane, ladder place, this fabric is cut by the straight line along the seam clip, and otch is crossed this clip, and go deep in the fabric body, to form a tongue-shaped member (19) hook of seam clip is installed.

Description

The connection of fabric ends

The present invention relates to the fabric of paper machine and similar machine, the belt conveyor of corrugated board milling train particularly, but be not limited to this.This corrugated board milling train belt conveyor comprises the flat fabric layer that multilayer is thick, and its end need be coupled together, and to produce the endless belt, is used for this paper machine.The weight of belt conveyor commonly used, such as, be 4Kg/m ²(Kilograms Per Square Meter).

In the prior art, traditional belt conveyor has sizable thickness, is difficult to satisfactorily it be connected into annular.Especially usually adopt the seam clip to connect, make the hook on this seam clip surround whole fabric thickness, this clip itself just defines bigger breaking joint on the belt conveyor bearing surface.

The object of the present invention is to provide a kind of improved type of attachment.

According to the present invention, a kind of paper machine that is made of flat fabric or the technical fabric of similar machine are provided, it comprises the multiply cloth layer that is interwoven by warp and filling, with along warp-wise or broadwise or existingly have along broadwise again along warp-wise, the additional wire that adjacent said tissue layer links up is formed, in addition, corresponding joint at this fabric, this fabric also comprises the joint component that cooperates with it, these parts comprise a seam clip, only connect and fixing said multiply cloth layer in some layer, these parts comprise that also covers a said seam clip, and with respect to the end connecting bridge of seam clip arranged offset.

According to a preferred construction feature, the fabric ends with complementary stairstepping is consistent on the gap between adjacent tissue layer, this fabric be cut open one parallel with fabric side and grew this seam clip and goed deep into the interior otch of fabric.

The present invention also comprises jointing method, promptly utilizes the seam clip, and the end of the paper machine that multiply cloth layer that will be woven into by longitude and latitude and the additional wire that those tissue layer are crosslinked together are formed or the technical fabric of similar machine links together.This method comprises following each step, it is the cutting fabric respective end, to form the step of complementary ladder-type structure, this cutting comprises along the plane that is parallel to fabric face, and the cutting of carrying out along the straight line between two adjacent tissue layer, this otch that is parallel to fabric face at fabric one end is extended down to fabric, to form a tongue-shaped member, the appropriate section that is used for fabric the other end on the relative mounting positions, this method also is included between this tongue-shaped member and this said fabric the other end, and the step of a seam clip is provided.

The present invention will be further by way of example, referential expression the accompanying drawing of several embodiments of the present invention describe.Wherein:

Fig. 1 has shown the annexation between fabric ends of the present invention.

Fig. 2 to Fig. 4 shows and is easy to adopt the representative fabric construction that is used for above-mentioned corrugated board milling train belt conveyor of the present invention.

With reference to each figure, particularly Fig. 1, the belt conveyor of corrugated board milling train is made up of the multiple-structure 11 that flat fabric constitutes, wherein only show its corresponding two

ends

12,13, utilize one fixing in the said tissue layer the only seam clip 14 of part layer, this structure is made annular.

In the process that fabric ends is coupled together, each

end

12,13 is cut into complementary stairstepping, be parallel to the fabric plane and cut corresponding to the

otch

15,16 of

fabric ends

12,13 along the straight line between the two

adjacent tissue layer

17,18, therefore, only cut off the connection yarn between adjacent layer, do not damage the integraty of each layer.The otch 15 that is positioned at fabric ends 12 places is cut fabric to 21 places, and seam clip 14 just is used for the appropriate section 22 on 21 tongue-shaped member 19 that form to otch 15 places and the relative fabric end 13.

Before moulding, fabric ends is handled with resin glue, so that obtain better notch effect.Before the hook 23 that inserts on the seam clip 14, glue is coated in is about to install on these tissue layer of this clip 14.

As from figure, obviously seeing, the upper layer of fabric layer 17 of fabric ends 12 extends across seam clip 14, it has also crossed the tissue layer 18,24 of relative fabric end 13, so, in seam clip region, just exist a continuous supporting plane significantly, completely different in the prior art fabric construction, this clip zone of this supporting plane intrinsic discontinuous plan.

Fig. 1 has illustrated this principle, promptly form complementary stepped end, utilize the seam clip more only to connect in the multiply cloth layer and utilize other tissue layer to cover the clip zone and by suitable cutting fabric formation tongue-shaped member, so that these processes of one group of hook in the clip hook are installed, this principle is applied to Fig. 2 respectively to each fabric construction shown in Figure 4, certainly, also can be used for other fabric construction.

With regard to fabric construction shown in Figure 2, this fabric construction is two comprehensive satins, and the

fixed line

29,31 of warp-wise is connected 26,27 these two surface layers respectively with interlayer 28, each layer that contains warp and filling knitted together, so that a fixing structure to be provided.Arrow 32 has been expressed the line of cut of each fabric ends, is easy to see, when cutting forming, has only the fixed line 29 of warp-wise to be cut off, thereby cuts the integraty of the multiply cloth layer of otch in the middle of can remaining on.

Fig. 3 has provided another structure, and this structure has a plurality of interlayers, and the cutting interlayer equally only cuts the fixed line 34,33 of warp-wise between the two adjacent tissue layer 35,36, and therefore, on its each limit, tissue layer 35,36 is still keeping the fixed fabric structure.In arrangement illustrated, otch 37 is opened between the second layer in six layers of weft yarn of this fabric and the 3rd layer.

Fig. 4 has provided another fabric construction again, and this structure has 4 tissue layer of from 41 to 44, and fixed line 45 connects together top three tissue layer 41 to 43, and fixed line 46 connects together following three layer 42 to 44.In this example, otch is driveed between the superiors 41 and 42, therefore, cut off fixed line 45, upper layer of fabric layer 41 is keeping fixing structure by fabric construction itself, and other three layer 42 to 44 connections by fixed line 46, is keeping fixing fabric construction.The tabby shape in this upper strata more helps the formation of tongue-shaped member, is beneficial to the installation of seam clip.

Obviously, though in arrangement illustrated, the fixed line in each fabric construction extends on warp direction, and if connect tissue layer with the fixed line of broadwise, also can obtain same effect.

The present invention is used on the belt conveyor of above-mentioned corrugated board milling train especially, the standard thickness of said fabric is 0.9 centimetre in other words, the gap that the seam clip is installed can be such as 1 centimetre wide, the material of belt conveyor or fabric is the textile material that is used for general type of the prior art, such as can include cotton thread or polyester blended yarn.
