Description

  In the seam felt for papermaking in which a loop is provided at the end of the felt to join the ends of the felt together, the joining core wire retaining structure for retaining the end of the core wire inserted into the loop And a method.

  In order to improve the workability of putting into a paper machine, so-called seam felts are widely used in which end felts are drawn into a felt run and both ends thereof are joined to each other to be endless. In this type of seam felt, loops formed at the end in the length direction by folding back warps constituting the base fabric are alternately meshed so that their center holes are aligned, and the core wire is formed in the common hole formed thereby. The structure which joins both ends through is common.

  In this seam felt end joining method, it is necessary to take measures to prevent the core wire inserted into the loop from slipping out. Conventionally, as a measure for preventing such core wire from coming out, a knot (ball knot) is attached to the end of the core wire. ) Or the end of the core wire is folded back to the loop side and inserted into a space outside the common hole in the loop (see Patent Documents 1 to 4).

  Further, in order to simplify the retaining treatment, the end of the core wire or the connecting portion connectable with the end of the lead wire for guiding the core wire into the common hole is provided on one end side, and the gripping portion is provided on the other end side. After inserting the core wire into the common hole in advance so that the connecting part and the gripping part protrude outside through the pull-in path, the end of the core wire or the end of the lead wire A technique is disclosed in which the end of the core wire is pulled into the pull-in path by pulling the gripping portion after connecting to the connecting portion (see Patent Document 5).

  However, in the method of forming a knot on the core wire as described above, when the ear of the felt comes into contact with the palm provided to guide the felt in the paper machine, the core wire is caught by the palm knot on the palm. There is a risk of failure to be disconnected. In addition, the width of the felt changes as it continues to be used, but since the movement of the core wire is constrained by the knot, the core wire cannot follow the dimensional change of the felt, causing a problem of cutting. Was undesirable.

  On the other hand, the method of folding the end of the core wire has the advantage that the core wire is not cut due to the knot as described above, but the end of the core wire is inserted into the space outside the common hole in the loop. In addition, since this work is forced in a work environment that is difficult to say in the paper machine, there is a problem that it requires skill in the work and is very troublesome for unskilled workers. .

  Also, as in Patent Document 5, even in the method of drawing the end portion into the space outside the common hole in the loop, the work of feeding the end portion of the core wire into this space is difficult because the inner diameter of the loop is extremely small. Furthermore, with the recent increase in the speed of operation of papermaking machines, thick and hard felts are often demanded, and resin processing is often performed on the felts. For this reason, it is difficult to draw the end of the core wire into a felt or hard felt that has been subjected to resin processing by the method of pulling the end of the core wire into the nonwoven fiber layer, and the end of the core wire is felt on the paper machine. The method of suturing to the part was very difficult.

  The present invention has been devised to solve such problems of the prior art, and its main purpose is to provide a loop at the end of the felt to join the ends of the felt together. Another object of the present invention is to provide a joining core wire retaining structure and method that can easily prevent the end portion of the core wire inserted into the loop in the seam felt for papermaking.

  The present invention for solving such a problem is for papermaking in which a loop (3) is provided at the end (2) of the felt (1) in order to join the ends (2) of the felt (1) to each other. A seam felt (1) joining core wire (4) retaining structure, wherein a through hole (5) penetrating in the thickness direction is provided in the vicinity (7) of the end (2) of the felt (1). The end portion (4a) of the core wire (4) inserted through the common hole (6) formed by alternately engaging the loop (3) is inserted into the through hole (5). It is configured as follows.

  According to the above configuration, by forming a through hole for drawing the core wire end portion in the vicinity of the felt end portion in advance, the core wire end portion is drawn even in the case of a resin-processed felt or a hard felt. The retaining work can be facilitated.

  According to one aspect of the present invention, it is preferable that a plurality of the through holes (5) are formed in the length direction of the felt (1).

  According to the above configuration, by providing a plurality of through-holes through which the core wire is inserted, the frictional resistance between the core wire and the through-hole is increased, so that the core wire is prevented from being pulled out, and the core wire can be hardly pulled out.

  According to one aspect of the present invention, the end (4a) of the core wire (4) includes a lead wire (8) that guides the insertion into the common hole (6), and the end of the through hole (5). The diameter (D1) is preferably configured to be approximately equal to the diameter (D2) of the lead wire.

  According to the said structure, the operation | work which penetrates a lead wire to a through-hole can be made easy by making the diameter of a through-hole and the diameter of a lead wire substantially equal. In general, the diameter of the lead wire is thinner than the core wire diameter, and the core wire guided to the through hole by the lead wire is inserted into the through hole narrower than the wire diameter. By increasing the frictional resistance between the core wire and the through hole, it is possible to prevent the core wire from coming out and to make it difficult to remove the core wire.

  According to one aspect of the present invention, one or more temporary fixing threads (9) are inserted into the through hole (5), and one temporary fixing thread (9) is inserted. In the case where the temporary fixing thread (9) has a wire diameter (D3) substantially equal to the diameter (D1) of the through hole (5), or two or more temporary fixing threads (9) are inserted. When the plurality of temporary fixing threads (9) are bundled, the maximum outer diameter (D3) is substantially equal to the diameter (D1) of the through hole (5), and the temporary fixing threads (9) Is preferably configured to be held in the through hole (5) until the end (4a) of the core wire (4) is inserted into the through hole (5).

  The through hole formed in the felt may be gradually closed after the formation. According to the above configuration, the through hole is blocked by inserting the temporary fixing thread substantially equal to the diameter of the through hole into the formed through hole and removing the temporary fixing thread before inserting the core wire end. The core wire end portion insertion work can be facilitated. The configuration in which one or two or more temporary fixing threads are inserted into the through-holes means that two temporary fixing threads are inserted into the through-holes or that the through-holes are sewn with one temporary fixing thread. And the case where this one temporary fixing thread is inserted in the same through-hole twice or more is also included. That is, the configuration in which one or two or more temporary fixing threads are inserted into the through-hole represents how many temporary fixing threads are inserted into the through-hole when attention is paid to only one through-hole. ing.

  According to one aspect of the present invention, the temporary fixing thread (9) is inserted into the plurality of through holes (5) by one thread, and the first surface (1a, 1b) of the felt (1). ) To the second surface (1b, 1a) is preferably formed so as to form a temporary fixing loop (10, 11).

  In order to prevent a foreign matter trouble during the papermaking operation, it is necessary to reliably remove the temporary fixing thread inserted through the through hole. Further, from the viewpoint of improving workability, it is preferable that the temporary fixing yarn can be easily removed. For example, when one temporary fixing thread is first inserted into one through hole and then inserted into a through hole adjacent to this one through hole, the temporary fixing thread is inserted from the temporary fixing thread insertion side of the one through hole. When pulling out, the temporary fixing thread is pulled out in contact with the inner surface of one through hole, the inner surface of the adjacent through hole, and the felt surface between the one through hole and the adjacent through hole. Since the contact causes frictional resistance between the temporary fixing thread and the inner surface of the through hole or the felt surface, there is a possibility that the frictional resistance may be increased by contact at three positions in the above example. If the frictional resistance at the time of extraction is large, the temporary fixing thread may be cut, entangled or entangled, and there is a possibility that reliable and easy removal of the temporary fixing thread may be hindered.

  In the above configuration, only a temporary fixing loop is formed in the through hole by inserting a portion of the temporary fixing thread facing the through hole of the single temporary fixing thread disposed along the felt surface so as to face the plurality of through holes. It can be inserted. In this state, when one end of the temporary fixing thread is pulled, the temporary fixing loop inserted in the through hole is extracted. The temporary fixing loop can be formed by using, for example, a sewing needle through which a temporary fixing thread is passed.

  According to the above configuration, when the temporary fixing loop is pulled out, the temporary fixing thread contacts only at one place on the inner surface of the through hole, and the frictional resistance is reduced and the temporary fixing is ensured as compared with the above example. Yarn can be eliminated. Further, since a temporary fixing loop is formed in each through-hole with a single temporary fixing thread, the temporary fixing thread can be reliably removed by pulling one end, and the operation can be facilitated.

  According to one aspect of the present invention, one temporary fixing loop (11) is extended from the through hole (5) longer than the plurality of other temporary fixing loops (10), and It is preferable that the temporary fixing loop (10) is inserted through the temporary fixing loop.

  In the above configuration, by pulling out one temporary fixing loop for a long time and inserting the drawn portion into another temporary fixing loop, the other temporary fixing loop is restricted from coming out, and one temporary fixing loop is By pulling out, the restriction of the other temporary fixing loop is released, and the temporary fixing thread can be eliminated. Thus, according to the above configuration, it is possible to prevent the temporary fixing yarn from falling off before the step of removing the temporary fixing yarn.

  The present invention is a method of preventing a core wire for joining a papermaking seam felt, in which a loop is provided at the end of the felt to join the ends of the felt together, and in the vicinity of the end of the felt A plurality of through holes penetrating in the thickness direction are formed in the length direction, and one or more temporary fixing threads are inserted into the through holes, and after removing the temporary fixing threads, An end portion of a core wire inserted into a common hole formed by alternately engaging loops may be inserted into the through hole.

  According to one aspect of the invention relating to a method for preventing a core wire for joining a seam felt for papermaking, the temporary fixing thread is inserted between the plurality of through holes by one thread, and the first of the felt It is preferable that a temporary fixing loop protruding from the surface to the second surface is formed.

  As described above, according to the present invention, in the papermaking seam felt in which a loop is provided at the end of the felt in order to join the ends of the felt to each other, the end of the end of the core wire inserted into the loop is prevented. It is possible to provide a method and a method for preventing a joining core wire from being configured so that the operation can be performed easily and reliably. As described above, the present invention can achieve a great effect in improving work efficiency.

It is a top view which shows the seam felt to which an example of the retaining structure of the joining core wire by this invention was applied. It is II-II sectional drawing of the felt shown in FIG. It is the perspective view seen from the A direction about the III section shown in FIG. It is a top view which shows the lead wire with which the core wire and the edge part of the core wire were equipped. It is sectional drawing which shows the penetration state to the through-hole of a temporary fixing thread in steps. This is an embodiment (1) of suturing and drawing the temporary fixing thread. This is an embodiment (2) of suturing and drawing the temporary fixing thread. This is an embodiment (3) of the suturing and drawing of the temporary fixing thread.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1-3, this felt 1 is formed by, for example, laminating and integrating a non-woven fiber layer on a base fabric (not shown), and the base fabric has a pair of warps entangled with a weft. A loop structure 3 (not shown) is formed, and an end joining loop 3 is formed at the end portion 2 in the length direction by folding back a yarn that becomes a warp. When the two felts 1 and 1 are joined together, the joining core wire 4 is inserted into the common hole 6 formed by alternately meshing so that the center holes of the loops 3 and 3 are aligned with each other. By inserting, both ends 2 and 2 are joined to each other.

  In this felt 1, a plurality of ends 4 a of the core wire 4 that are inserted into the common holes 6 of the loops 3 and 3 and protrude from the ears (ends in the width direction) of the felt 1 are formed in the length direction of the felt 1. The core wire 4 is prevented from coming off by being inserted into the through hole 5.

  As shown in the figure, the core wire 4 is sewn in parallel to the plurality of through-holes 5 so that the end portion 4a is prevented from coming out due to the frictional resistance between the base fabric or the non-woven fiber layer constituting the felt and the core wire 4. . In addition, it is preferable to form 4 to 8 through holes 5 within 5 cm from the felt end 2 as the range L in the length direction and 4 to 8 near the ears as the range 7 in the width direction. With such a configuration, a sufficient retaining effect can be obtained, and the core wire 4 is not easily displaced by an external force acting while running in the paper machine, and the end portion follows the dimensional change of the felt 1 during continuous use. The movement of 4a may be allowed. The stitching of the core wire 4 into the through hole 5 is not limited to the side stitching as shown in the figure, and can be appropriately selected.

  Referring also to FIG. 4, a lead wire 8 is connected to the end 4 a of the core wire 4. The lead wire 8 is used for guiding the core wire 4 into the common hole 6 of the loop 3, and is provided on both the front end side and the end side of the core wire 4 here. The core wire 4 is usually a bundle of a plurality of (for example, five) thread materials, and the lead wire 8 is fixed to the end portion 4a of the core wire 4 with an adhesive or the like.

  The diameter D1 of the through hole 5 is made substantially equal to the diameter D2 of the lead wire 8. According to this configuration, the lead wire 8 can be easily inserted into the through hole 5. In general, the diameter D2 of the lead wire 8 is smaller than the wire diameter of the core wire 4 (the outer diameter when a plurality of core wires are bundled), and is guided to the through hole 5 by the lead wire 8. Since the core wire 4 is inserted into the through hole 5 narrower than its diameter, the frictional resistance between the core wire 4 and the through hole 5 is increased, and the core wire 4 is prevented from coming out.

  The through hole 5 formed in advance in the felt 1 may be gradually closed after the formation. In the paper machine, the end felt 1 is pulled into the felt runn and both ends are joined to each other to make it endless. During the storage and transfer period after the end felt 1 is manufactured, It is necessary to prevent the through hole 5 from being blocked.

  Referring to FIG. 5, the through hole 5 can be prevented from being blocked by inserting the temporary fixing thread 9 having an outer diameter D <b> 3 substantially equal to the diameter D <b> 1 of the through hole 5 into the formed through hole 5. Here, the outer diameter D3 of the temporary fixing thread 9 is the wire diameter of the temporary fixing thread 9 when one temporary fixing thread 9 is inserted into the through-hole 5, and two or more temporary fixing threads. When 9 is inserted, it becomes the maximum outer diameter when the plurality of inserted temporary fixing threads 9 are bundled. When the loop 10 (11) formed in the temporary fixing thread 9 is inserted into the through-hole 5 as in the present embodiment shown in FIG. 5 (c), the single temporary fixing thread 9 is By inserting two or more times into the same through hole 5, two or more temporary fixing threads 9 are inserted into the through hole 5. Therefore, the outer diameter D3 in the embodiment of FIG. 5C is the maximum outer diameter when two temporary fixing threads 9 are bundled.

  In order to prevent a foreign matter trouble during the papermaking operation, it is necessary to reliably remove the temporary fixing thread 9 inserted through the through hole 5. Further, from the viewpoint of improving workability, it is preferable that the temporary fixing yarn 9 can be easily removed.

  Next, referring also to FIG. 5 (b), the portion 9a facing the through holes 5,... 5 of the temporary fixing thread 9 is inserted into the through hole 5, and the through hole of the second surface 1b of the felt. Temporary fixing loops 10 and 11 projecting from 5 are formed. Since only these temporary fixing loops 10 and 11 are inserted into the through hole 5, only the inner surface of the through hole 5 comes into contact when the temporary fixing thread 9 is extracted. With this configuration, it is possible to reduce the frictional resistance, prevent the temporary fixing yarn 9 from being cut, entangled, and entangled, and reliably eliminate the temporary fixing yarn 9.

  Next, referring also to FIG. 5C, one temporary fixing loop 11 has a longer protruding portion 11a than the plurality of other temporary fixing loops 10, and the protruding portion 11a has a plurality of other temporary fixing loops. The inner hole of the stop loop 10 is inserted.

  By configuring in this way, it is possible to restrict the other temporary fixing loop 10 from coming out of the through hole 5 by one temporary fixing loop 11. Further, by pulling one end 9b of the temporary fixing thread and extracting one temporary fixing loop 11, the restriction of the other temporary fixing loop 10 is released, and the temporary fixing thread can be eliminated. Such a configuration can prevent the temporary fixing yarn 9 from being unwound or detached until the ends 2 and 2 of the felts 1 and 1 are joined.
