[0011]

BEST MODE FOR CARRYING OUT THE INVENTION In order to increase the strength by adhering fine fibers forming a warp and to prevent the fluff from being exposed by covering the warp surface, glue is used as a treating agent, and furthermore, slip of the warp is prevented. For the purpose of improving, for example, an oil agent or wax is applied to the warp sheet using a warp treating agent applicator as a treating agent. The following embodiments are embodiments in which a warp sizing machine is used as a warp treating agent applicator and glue is applied to a warp as a treating agent.

FIGS. 1 and 2 show the construction of a stop mark preventing device 1 of a warp gluing machine as a warp treating agent applying machine according to the first and third aspects. First, in FIG. 1, a large number of warp yarns 2 are unwound from a creel 3, pass through a reed 4, come into contact with a guide roll 5, and are then sandwiched between a tension roll 6 and a nip roll 7 to form a sheet-like warp sheet. 8, through a fluff detector 9 and a reed 10, and wound around the first guide roll 11 on the upstream side, and the direction is changed in a downward direction. On one side, the first glue application roller 13 as an application roller is used. Contact and then on the other side a second application roller
After contact with the glue application roller 14 of the second guide roll 1
2, the direction is changed in the horizontal direction, for example, and after entering the hot air drying chamber 16 of the hot air drying device 15, the zigzag comb 1
7. After being passed through the length measuring roll 18, it is wound around the warper beam 20 while being pressed by the press roll 19.

Before and after the hot air drying device 15, the warp sheet 8
The warp path of the second guide roll 12 and the length measuring roll 1
8 and is set in the horizontal direction. For this reason, the warp sheet 8 is placed in the horizontal hot air drying chamber 16.
The vehicle travels in a straight line without contact through the entire area from the entrance to the exit.

FIG. 2 shows supporting portions such as the first guide roll 11 and the second guide roll 12. The first guide roll 11 is rotatably attached to a roll lever 21 by a roll shaft 28, and the reed 10 is fixed to the roll lever 21. The roll lever 21 is rotatably supported by a horizontal fulcrum shaft 22 of a bracket 23 fixed to the frame 24, and is connected by a pin 27 between a cylinder bracket 25 of the frame 24 and one end of the roll lever 21. The first guide roll 1 is moved by the air cylinder 26 in the direction in which the warp sheet 8 is separated from the first glue applying roll 13.
1 so that it can be moved.

The second guide roll 12 is rotatably supported by a roll shaft 31 at the tip of a piston rod 30 of an air cylinder 29 fixed to the frame 24 in a horizontal direction. When the machine is stopped, the warp sheet 8 is separated from the second glue applying roller 14,
It moves substantially horizontally in a direction in which the warp path is shortened, that is, in a range not contacting the entrance of the hot air drying chamber 16.

When the machine is stopped, the first guide roll 11 and the second guide roll 12 move to the positions shown by imaginary lines in FIG. It is separated from the second glue applying roller 14 to absorb a change in the length of the warp path caused by these movements. Note that the first glue application roller 13 and the second
The lower side of the glue application roller 14 is in contact with the size liquid 34 accommodated in the size liquid boxes 32 and 33, respectively.

Here, the length of the warp path is upstream and downstream of the pair of guide rolls (the first glue applying roller 13 and the second glue applying roller 14), and
Are determined based on the warp route reference positions A and B which are constrained by contacting with a fixed roll or the like. One warp path reference position A is set at a contact position between the tension roll 6 and the nip roll 7, as shown in FIG.
The other warp path reference position B is set at an upstream contact position (contact start position) between the warp sheet 8 and the length measuring roll 18. Before and after the movement of the warp sheet 8, a pair of the first guide roll 11 and the second guide roll 12 are arranged so that the lengths of the warp paths between the warp path reference positions AB are the same.
Stop position is set. "The first guide roll 11,
"The length of the warp path between the warp path reference positions AB before and after the movement of the second guide roll 12 is the same." Even after that, warp paths having substantially the same length are included within a range in which the warp sheet is not loosened due to the decrease in tension and the warp or the snare ring does not occur.

As described above, in the gluing process, the upper and lower pair of the first guide roll 11 and the second guide roll 12 cause the warp sheet 8 therebetween to divide the warp sheet 8 into the first glue applying roller 13 and the second glue applying roller 14. The warp sheet 8 is moved together with the first glue applying roller 13 and the second glue applying roller 13 when the machine is stopped.
And at the same time, keep the warp path length substantially constant between the warp path reference positions A and B.

As an example of the operation conditions for the gluing, the warp speed is 200 [m / min], the size diameter of the glue applying rollers 13 and 14 is 60 [mm], the number of rotations is 8 [rpm], and the peripheral speed is 1.
For example, 5 [m / min] is set. During the gluing operation, the first
Guide roll 11 and second guide roll 12
Both are set at the positions shown in FIG. For this reason, the warp sheet 8 is glued on one side in contact with the first glue applying roller 13 and then in contact with the second glue applying roller 14 on the other side. Then, after gluing, the warp sheet 8 enters the inside of the hot air drying chamber 16, and after being dried, is wound up by the warper beam 20.

When the machine stops during such a gluing operation, the second guide roll 12 is driven by the air cylinder 29 and horizontally moves in a direction to separate the warp sheet 8 from the second glue applying roller 14. In FIG. 2, it stops at the position shown by the imaginary line. As a result, the length of the warp path of the warp sheet 8 is reduced.

At the same time, the first guide roll 11
Is driven by the air cylinder 26 and the roll lever 21,
In order to move the warp sheet 8 away from the first glue application roller 13 and correct the decrease in the length of the warp path caused by the movement of the second guide roll 12, the warp sheet 8 is increased in the right direction. It moves diagonally upward and stops at the position indicated by the imaginary line in FIG.

After the movement of the first guide roll 11 and the second guide roll 12, the length of the warp path between the warp path reference positions AB does not substantially change from that before the movement. For this reason, there is almost no change in the warp tension, and there is no loosening of the warp, an increase in the tension, and no adverse effects due to them. In this way, the warp sheet 8 has the first side on one side.
And the second glue applying roller 1 on the other side
Separated from 4. Therefore, no stop mark is generated on the warp sheet 8 due to the stoppage of the machine, and the adverse effect thereof can be prevented.

The second guide roll 12 moves in a substantially horizontal direction at the same height as the inlet of the hot air drying device 15. Since the warp paths in the hot air drying chamber 16 and the hot air drying chamber 16 before the movement are both provided horizontally, the warp sheet 8 does not come into contact with members other than the inlet of the hot air drying chamber 16 after the movement. There are no stop marks and no fluff due to glue.

As in this specific example, it is preferable that there is no member, such as a roll, for regulating the warp sheet 8 inside the hot air drying chamber 16, but there is a roll or the like that changes the direction of the warp sheet 8. You may. Normally, in order to prevent the glue from sticking, the first glue applying roller 13 and the second glue applying roller 14 are rotated by the glue liquid 34 while the machine is stopped.

Next, the example of FIG. 3 corresponds to claims 1 and 3, and the first glue applying roller 13 and the second glue applying roller 14 are moved in the opposite directions to those of FIGS. Corresponding to the first guide roll 1 when the machine is stopped.
The first and second guide rolls 12 are moved in a direction opposite to that of the example shown in FIGS.

In the example shown in FIG. 4, a first guide roll 36 which can be moved in the horizontal direction is provided between an auxiliary guide roll 35 provided at a fixed position and the first glue applying roller 13, and the first guide roll 36 is provided. The roll 36 is rotatably provided by a roll shaft 39 with respect to the tip of a piston rod 38 of an air cylinder 37 in a horizontal direction. When gluing, air cylinder 3
7, the warp sheet 8 is brought into contact with the first glue applying roller 13 by the first guide roll 36 by advancing the piston rod 38.
By retracting the guide roll 36, the warp sheet is separated from the first glue applying roller 13. According to this example, from the tension roll 6 to the auxiliary guide roll 3
Since the warp path does not change during the period from 5, the reed 4 does not have to be moved.

The stop mark preventing device 1 of the warp gluing machine shown in FIG. 5 corresponds to claims 2 and 4, and has a hot air drying device 15 similar to the specific example of FIG. When the machine is stopped, the second guide roll 12 is provided so as to be horizontally movable in the direction of shortening the length of the warp path, that is, in the direction of the hot-air drying device 15, and moves the warp sheet 8 to the second glue applying roller 1.
Separated from 4.

A warp separating roll 40 is provided between the first guide roll 11 and the first glue applying roller 13 as a guide member on a piston rod 42 of an air cylinder 41 by a roll shaft 43 so as to be able to advance and retreat. When the machine is stopped, it advances and comes into contact with the warp sheet 8 between the first guide roll 11 and the first glue applying roller 13 to bend,
The warp sheet 8 is separated from the first glue applying roller 13 and the length of the warp path is increased. The warp separation roll 40 as a guide member is preferably provided rotatably, but may not be rotatable. During the gluing operation, the warp separation roll 40 is at a position not in contact with the warp sheet 8, but may be at a position where it does.

In this specific example, as in the other examples, the lengths of the warp paths before and after the movement are substantially the same. Since the warp path between the tension roll 6 and the first guide roll 11 does not change, the reed 4 does not have to be moved. The warp separation roll 40 is composed of a pair of first glue application rollers 13,
Is provided on the upstream side of the glue applying roller 14, the glue liquid 34 does not adhere.
There is no stop mark due to glue drop.

In the above embodiment, the warp sizing machine as the warp treating agent applicator uses the glue applying roller as the applying roller to adhere the paste as the treating agent to the warp sheet. . Further, in a warp oiling machine as a warp treating agent applying machine, an oil is attached to a warp sheet by supplying an oil to an oiling roller, and in a warp waxing machine as a warp treating agent applying machine,
The wax is supplied to the warp sheet by supplying the wax to the waxing roller.

[0031]

According to the first aspect, when the machine is stopped due to thread breakage or the like, the two guide rolls move in a direction to separate the warp sheet from the application roller. The guide roll and the guide member move in a direction to separate the warp sheet from the application roller, the warp sheet separates from the application roller, and stop at a position where the length of the warp path is the same as before the movement. Thereby, it is possible to prevent a stop mark from being generated on the warp sheet. In addition, since the length of the warp path is the same before and after the movement, the warp tension does not change, so that the warp does not loosen, there is no occurrence of entanglement between adjacent warps due to twisting or snare ring, and the warp tension is reduced. When it increases, warp elongation and change in warp physical properties occur and quality is impaired, but this is not the case.

Further, according to the third and fourth aspects, when the machine is stopped, the guide roll on the downstream side moves within a range where the warp sheet is not in contact with the inlet of the hot air drying device, and moves the warp sheet on the downstream side. Away from the application roller. Claim 3
Then, the guide member on the upstream side moves, and according to the fourth aspect, the guide member comes into contact with the warp sheet before applying the treatment agent, so that the guide member can move while avoiding the drop of the treatment agent from the warp sheet. The sheet is separated from the application roller on the upstream side. Thereby, it is possible to prevent the occurrence of stop marks on the warp sheet. Further, even after the warp sheet is moved, the warp sheet does not come into contact with the inlet of the hot-air drying device, and the warp sheet does not have any stop mark or fluff due to the drop of the processing agent. Further, since it is not necessary to newly provide a member for preventing contact, there is no occurrence of a stop mark due to the provision of a new member.
