Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method in which both ends of a seam felt are pulled together to engage a seam loop.
The present invention relates to a seam felt joining aid for joining a core wire to a common hole formed thereby.

[0002]

2. Description of the Related Art Generally, in a press part for dewatering moisture from a wet paper, means for increasing the amount of dewatering of the press include increasing the roll pressure, increasing the roll hardness, and increasing the pressing time by a pressure shoe. Is adopted. In such a high pressure part, felt is interposed for the purpose of transporting and dewatering the wet paper web.
Alternatively, since the felt interposed between the roll and the shoe press blanket is quickly flattened, a laminated felt obtained by laminating at least two heavy woven fabrics on a base cloth is used.

[0003] Since the laminated felt is hard and heavy, the use of seam felt, which is open-ended and is endlessly joined on the paper machine, has recently become mainstream in order to facilitate the work of inserting the laminated felt into the paper machine. . Such an open-ended seam felt is shown in FIG.

As shown in FIG. 5 (a), the seam felt 51 uses two woven fabrics 53 and 54 as a base cloth 52, lays bat fibers 55 on the base cloth 52, and entangles and integrates them by needling. When seam loops 53a and 53b and 54a and 54b are provided at both ends of the woven fabric, in order to join these seam loops 53a and 53b and 54a and 54b, the felt 51 Elements 56a and 56 constituting the coupling tool 56 near both ends
5b, and the temporarily fixed elements 56a and 56b are connected as shown in FIG. 5 (b) to draw both ends of the felt 51 to form a mountain shape, thereby forming the seam of the lowermost woven fabric. The loops 54a and 54b are engaged with each other, and the core wire S is inserted into the common hole and joined. In this case, if the chevron is still made, the loops 53a and 53b of the second woven fabric
Cannot be engaged with the coupling 56
The connection between the loops 53a and 53b of the second woven fabric is performed by releasing the connection between the elements 56a and 56b.

[0005]

However, after the seam loops 54a and 54b of the lowermost woven fabric are engaged with each other, and the core wire S is inserted into the common hole and joined, as described above, the element When the connection with the seam felts 56a and 56b is released as shown in FIG. 5C, the seam felt is long and wide and the weight increases, so that both ends of the seam felt 51 are separated from each other (arrow C1). ,
(C2 direction), the meshing between the loops 53a and 53b of the second woven fabric is displaced, and the common hole (hatched portion) is reduced or misaligned. It may take some time.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to easily join all seam loops provided at both ends of two or more woven fabrics on a paper machine. It is an object of the present invention to provide a seam felt joining aid that can be used.

[0007]

In order to achieve the above object, a seam felt joining aid according to the present invention comprises a base fabric composed of two or more woven fabrics, and two of the woven fabrics are provided. A joining tool which is temporarily fixed opposite to both ends of a seam felt provided with seam loops at both ends of the woven fabric and joined together for joining the seam loops, wherein the number of seam loops joined The structure is such that the meshing of the seam loop is ensured for each woven fabric, and the common holes are accurately aligned on one line.

A second aspect of the present invention is a seam felt joining auxiliary tool, wherein the connecting tool to be connected to each other is a slide fastener, and is simply and simply slided by a slider. , So that both ends of the seam felt can be pulled with a strong force.

A third aspect of the present invention is a seam felt joining auxiliary tool, wherein one of the connecting elements of the connecting tool is one and the other is plural, and the connecting elements are provided near both ends of the seam felt. When the slide type fasteners are temporarily installed opposite to each other, the fastener elements can be saved and the cost can be reduced.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a seam felt, and the seam felt 1 is formed by laminating bat fibers 3 on a base cloth 2 and entangled and integrated by needling. 5 and seam loops 4a and 4b, 5a and 5
b. The seam loops 4a and 4b, 5a and 5
b may be formed by folding a vertical thread of the woven fabrics 4 and 5 by forming a loop, or by forming a hook member having a loop on both ends of the woven fabrics 4 and 5 or other. Of course.

In the vicinity of the lower surface of both ends of the seam felt 1, a connecting element 6 constituting the joining aid 6 of the present invention is provided.
a and 6a 'and 6b and 6b' are temporarily fixed to face each other. Tips A of the first-stage coupling elements 6a and 6a '
Is La from the loop end B of the felt (empirically 10 mm
(Up to 30 mm). This is because when the elements 6a and 6a 'are connected, both ends of the felt 1 are drawn together to form a chevron as shown in FIG. 2, whereby the seam loops 5a and 5b of the lowermost woven fabric are meshed with each other. Effectively works to align the common holes.

The second-stage connecting elements 6b and 6
The tip A 'of b' is inside the loop end B of the felt by Lb (1 to 2 mm empirically). This is because when the connection between the elements 6b and 6b 'is released as shown in FIG. 3, the ends of the seam felt 1 are separated (arrow C).
It effectively functions to prevent the common hole (hatched portion) from being displaced by the engagement of the loops 4a and 4b even when a force in the direction (1, C2) is received. In the third and subsequent stages (not shown), the tip of the element may coincide with or be outside the loop end of the felt.

The joining aid 6 of the present invention connects the respective elements 6a and 6a 'and 6b and 6b' to each other to draw both ends of the seam felt 1 to engage the seam loops 4a and 4b, 5a and 5b with each other. As described above, it is possible to provide a function for matching. As long as the function is provided, any structure may be used. In this example, a slide fastener (zipper) is used. This is because it has a structural feature that can be easily connected only by sliding the slider, and that can draw both ends of the seam felt with a strong force.

Each element 6 of the joining aid 5 of the present invention
a and 6a ', 6b and 6b' are temporarily fixed to the last, and after seam loops 5a and 5b and 4a and 4b are meshed with each other and the core wire is joined through the common hole, the seam felt 1 Will be removed.
Therefore, it is preferable that the battery is firmly fixed in a state where subsequent removal becomes easy. As this temporary fixing,
It is excellent to use "double chain stitching", in which one end of the sewing thread is unwound so that the sewn portion is transmitted one after another.

The elements 6a and 6a ', 6b and 6b' of the joining aid 6 of the present invention are connected to seam loops 4a, 4b and 5b.
Although a plurality (two in this example) is provided corresponding to the number of junctions of a and 5b, even if both elements have the same number (two each) as shown in FIGS. As a matter of course, one may be provided as "1" and the other as a plurality (two). In the latter case, since one of the elements is shared, the cost can be reduced accordingly.

Next, the operation of the joining aid 6 of the present invention will be described with reference to FIGS. When the seam felt 1 is inserted into the paper machine, the lowermost base fabric is joined. First,
As shown in FIG. 2, the first-stage joining elements 6a and 6a 'of the joining assistant 6 of the present invention are joined. As a result, both ends of the felt 1 are drawn to form a chevron, and the lowermost woven fabric 5 is formed.
Since the seam loops 5a and 5b are engaged with each other, the core wire S is inserted into a common hole formed thereby and joined.

As described above, if the first-stage elements 6a and 6a 'remain connected to form a chevron, the seam loops 4a and 4b of the second woven fabric 4 do not mesh with each other. 3, the first stage elements 6a and 6
As soon as a 'is released, the second stage elements 6b and 6b' are immediately connected. That is, when the first-stage elements 6a and 6a 'are released from coupling, both ends of the seam felt receive a force in the direction in which the seam felts are separated (directions of arrows C1 and C2), but the second-stage elements 6b and 6b ', The common holes are securely aligned between the loops 4a and 4b of the second woven fabric as shown by hatching, and the work of inserting and bonding (seaming) the core wire can be performed easily and reliably.

[0018]

As described above, in the seam felt joining aid according to the present invention, the base fabric is formed of two or more woven fabrics,
A joining tool which is temporarily fixed to both ends of two or more woven fabrics having seam loops at both ends thereof, in the vicinity of both ends of the seam felt, and joined together for joining the seam loops. Therefore, since a plurality of seam loops are provided corresponding to the number of seam loops joined, the meshing of the seam loops for each woven fabric can be ensured, and the common holes can be accurately aligned on a line. This has an excellent effect that the seaming operation can be greatly reduced.

Further, the seam felt joining aid according to the second aspect of the present invention is characterized in that the joining tools to be joined to each other are slide fasteners, so that they can be easily operated by simply sliding the slider. Moreover, the present invention has an excellent effect that both ends of the seam felt can be pulled with a strong force.

According to a third aspect of the present invention, there is provided an auxiliary tool for seam felt bonding, wherein one of the connecting elements of the connecting tool is one and the other is plural. When the slide fastener is temporarily fixed in the vicinity of the fastener, an excellent effect of saving the fastener element and reducing the cost can be achieved.
