Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a dryer canvas for II paper, and more specifically, to facilitate the operation of hanging a dryer canvas in the drying section of a paper machine. This invention relates to a dryer canvas equipped with a guiding cloth for drying.

(Prior art) As a dryer canvas for papermaking, metal hooks are planted along the entire width of both ends in the length direction, the warp threads of the canvas body are extended and folded back, and a joint base fabric is sewn on. A large number of joining loops are provided to protrude in the length direction, one joining loop and the other joining loop are butted against each other in an interlocking manner, and a joining core wire is inserted into these joining loops, whereby the above-mentioned dryer A device in which canvases are joined in an endless manner is known.

In addition, in order to facilitate the installation of the dryer canvas into a paper machine with a large number of cylinders arranged, one end of the dryer canvas was
It is known to attach a guiding cloth as described in Japanese Patent No. 356 and the like. That is, a large number of string holes are drilled along one end of the thick fabric, which has a width similar to that of the dryer canvas described above and a length of several tens of centimeters, and a thread is inserted only in the longitudinal direction near the other end. length 6-10m
A blind-shaped part of the length of 1.m is formed over the entire width to serve as a guide cloth, and one joining loop of a new dryer canvas is inserted into the gap between the blind-shaped parts.

A protective core wire is inserted into the protruding end to join the two, and a joining string is inserted into the string hole at one end of the guiding cloth, respectively.
Connect the above-mentioned guiding cloth with the above-mentioned string to the end of the rope that has already been wrapped around multiple cylinders of the paper machine or the end of the old canvas, and pull the above-mentioned rope or the old canvas. A new canvas is wound around the cylinder, and then the guide cloth is removed from the new canvas, the joining loops at both ends are engaged, and the joining core wire is inserted into these joining loops.

(Problem to be Solved by the Invention) In order to join both ends of a dryer canvas wrapped around a large number of cylinders, it is necessary to pull both ends of the above-mentioned papermaking canvas and connect one joining loop to the other. Since the joining core wires had to be inserted into these joining loops while being accurately engaged with the joining loops one by one, a great deal of labor and time was required for this joining work. In particular, the joining loop of the dryer canvas is small.

If the dryer canvas has a wide width of several meters or more, the weight of the dryer canvas is large, and this weight acts to pull the ends of the dryer canvas apart, and the work area for engaging the joining loops is large. The above work was extremely difficult due to poor footing and insufficient lighting. In addition, the work of inserting the joining loop of the dryer canvas into the blind-like part of the conventional guide cloth and inserting the protective core wire through the protruding end of the loop is also quite troublesome and requires a long time.

(Means for solving the problem) A large number of joining loops are protruded in the length direction along the entire width of both lengthwise ends of the dryer canvas, and one joining loop and the other joining loop In a dryer canvas for paper manufacturing in which the core wires for joining are inserted through these joining loops by interlocking butts, one set of slide fasteners is attached to the entire width of the upper surface of one end and the other end of the dryer canvas. and the other tape are removably attached so that their interlocking elements are located above or near the joining loop,
The other end of the guiding fabric, which has approximately the same width as the dryer canvas and has a number of string holes perforated on one end, is sewn to the other end of the one tape. It is removably joined via the same tape as the above tape.

(Function) When winding a large number of cylinders, pass the string through the string hole of the guide cloth as in the past, and attach the above guide cloth to the end of the old dryer canvas that has already been wrapped around the paper machine. Connect with the string, then pull the old dryer canvas, and wrap the new dryer canvas around the multiple cylinders via the guide cloth. After one end of the new dryer canvas has returned to its original position, remove the guide cloth from one end of the new dryer canvas by opening the slide fastener connecting this end to the guide cloth, and then remove the guide cloth from one end of the new dryer canvas. The slide fastener tape and the slide fastener tape at the other end are brought together and held in tension, their joints are engaged and connected, and then, while opening the closed slide fastener little by little, While correctly engaging the joining loop with the other joining loop, insert the joining core wire into these joining loops, and after completing the insertion over the entire width,
Remove one end of the tape and the other end of the tape from the dryer canvas.

(Example) In FIG. 1 and FIG. 2, ■ is a dryer canvas, and a large number of joining loops 2 and 3 made of warp threads are protruded from one end 1a and the other end 1b of the canvas, respectively. One tape 4 and the other tape 5 of the slide fastener are attached to the one end 1a and the other end ib, respectively, by the stitches 6 of a chain stitch sewing machine, and the same tape 7 as the other tape 5 is attached to one tape 4. The guiding cloth 8 is joined through the cord passing hole 8 bored at the other end of the guiding cloth 8.
An eyelet 9 (see Fig. 2) is attached to a. In addition.

4a, 5a-7a are the joints fixed to the tapes 4, 5.7, respectively, and the slider 10 (see Fig. 5).
is attached to tape 4.

In the above structure, as shown in FIG.
Insert the string 12 through the eyelet 9) and attach the old dryer canvas 1.
A new dryer canvas 1 is connected to the dryer canvas 1 through the guide cloth 8, the machine base is driven, the dryer canvas 1 is wound around a cylinder (not shown), the string 12 is untied, and the old dryer canvas is untied. 11 to guide cloth 8
Then, the tapes 4 and 7 of the slide fastener joining the guide cloth 8 and one end of the dryer canvas 1 are opened by sliding the slider 0, thereby removing the guide cloth 8 from the dryer canvas 1. reference).

Subsequently, one tape 4 and the other tape 5, that is, both ends of the dryer canvas 1 are pulled together, and the interlocking elements 4a and 5a of the two are engaged by sliding of the slider 1O, thereby temporarily joining the dryer canvas 1 into an endless shape. Next, as shown in FIG. 5, the slider lO is slid little by little to open the above interlockers 4a, 5a, and the joining core wire 13 is inserted while accurately engaging one loop 2 and the other loop 3. After the entire width has been inserted, remove the fastener tape 4.5 from the dryer canvas 1.

The above example is a slide fastener tape 4.5.7
Since it is attached by chain stitch 6, it can be easily removed.

Next, to explain an experimental example, a door with a width of 6.25 m

Loops 2 for joining with warp threads at both ends of the lier canvas l,
3 and a slide fastener tape 4 on both ends.
5 is sewn by a sewing machine, and a guide cloth 8 with a width of 6.25 m and a length of 40 mm is connected to one end with tape 4.7. Furthermore, string passing holes 8a are made in the guide cloth 8 at intervals of 30C11, and eyelets are formed. The guide cloth 8 with attached guide cloth 9 was connected to the old dryer canvas 11 on the paper machine with a string 12 and passed through the paper machine, then the guide cloth 8 was removed and both ends of the dryer canvas l were joined. The time required from removing the cloth 8 to completing the joining was 15 minutes by four workers. On the other hand, when a conventional guide cloth without a slide fastener attached was used, it took eight workers and one hour.

(Effect of the invention) Since the induction cloth is connected to one end of the dryer canvas with a slide fastener, by connecting this induction cloth to the old dryer canvas, the dryer canvas can be wrapped around the cylinder of the paper machine without damaging it. The guide cloth can be removed very easily when the winding is finished. Then, the ends of the dryer canvas that have been wrapped as described above can be manually pulled together, temporarily joined in an endless manner as if closing a slide fastener, and then the joining loops can be engaged while opening little by little. The joining of both ends of the can be performed more accurately and easily than in the past, with fewer people and in a shorter time.
