Next, the operation of the winding step will be described.
As shown in FIG. 1, the filter element 14 manufactured in the previous step is stored in the buffer 69 for the length of one wound filter element 15. Both ends in the width direction of the filter element 14 are inserted between the opposing claws 711 and 712 of the winding pin 71 in the open state as shown in FIG. 16 by a feeding device (not shown). After that, the cylinder 73 is operated and the filter element 14 is pinched by the counter claws 711 and 712 of the winding pin 71.

Thereafter, the sealing adhesive applying device 703 attached to the robot 701 applies the sealing adhesive 95 to the outer side surface of the corrugated filter medium 11 (FIG. 23). Also, the detector detects the diameter required for the winding filter element 15,
Stop winding. After that, the filtering element 14 is cut by the cutting unit 702, and the remaining unwound end portion is wound again while being sealed with the adhesive 95 (FIG. 25).

Then, after the winding end is positioned right above the winding shaft by a control unit (not shown), the cylinder 75
Is operated to retract the flat filter media 71, 71 to remove the take-up pins 71, 71 from the winding filter element 15.
At this time, the winding filter element 15 has the winding end 131.
(FIG. 25) is moved to the index unit 791 while being positioned.

When the index unit 791 is then inverted, the winding end 13 of the winding filter element 15 is
The adhesive application device 792 waiting at the position 1 applies the adhesive 96 to the winding end portion and adheres the winding end end (FIG. 25). Then, the winding filter element is taken out by a not-shown conveying device and conveyed to the subsequent step. The wound filter element 15 is manufactured by repeating the above series of operations.

As is known from the above, according to this example,
The tape-shaped filter medium 1 taken out from the hoop material 21 is formed into the corrugated filter material 11 by the corrugating machine 3, and then the adhesive 91 is applied to the top of the tape-shaped filter material 11 by the adhesive application device 4, while the flat filter medium taken out from the hoop material 22. 12 to end coater 25
The end sealing adhesive 93 is applied by the
Are continuously bonded by a heat bonding device. And
An end sealing device is used to end-seal the filter element 14
And the winding filter 7 is used to manufacture the winding filter element 15. Therefore, according to this example, the filter element 14 and the wound filter element 15 can be continuously and efficiently manufactured.

Example 2 In this example, as shown in FIG. 17, the peaks 311 of the concave roller 31 and the corrugated filter medium 11 do not contact the valleys of the molding roller 32 corresponding to the convex rollers of the corrugating machine 3. Deep flat bottom groove 3
20 is formed (compare with FIG. 6). This example is an example corresponding to the fourth invention. Others are the same as in the first embodiment. According to this example, the valley portion of the forming roller 32, which is the convex roller, has the deep flat-bottom groove 320. for that reason,
No stress is applied to the corrugated filter medium 11 during molding, and the corrugated filter medium 11 is not damaged or broken. In addition, the same effect as that of the first embodiment can be obtained.

Embodiment 3 In this embodiment, as shown in FIGS. 18 and 19, a slit 46 for an adhesive jet is provided in an adhesive coating device 4 for coating an adhesive on the top 111 of the corrugated filter medium 11. is there.
This example is an example corresponding to the fifth invention. The adhesive applying device 4 has a main body 45 having a triangular vertical section, an adhesive reservoir 452 provided in the main body 45, and slits 46 provided at two locations above the adhesive reservoir 452. Adhesive pool 45
2, a pipe 4 connected to an adhesive supply device (not shown)
Connect 4

Below the main body 45, a plate-like cover 47 is fixed via a sealing material. Also, two heater insertion holes 454 are formed in the main body 45 so as to be located on both sides of the adhesive reservoir 452. Each heater insertion hole 454 inserts the heater connected to the temperature controller. Others are the same as in the first embodiment.

In the adhesive application device 4 of this example, the pipe 4 is inserted into the adhesive reservoir 452 by the adhesive supply device.
4, the adhesive is supplied, and then the adhesive is jetly applied from the slit 46 to the top 111 of the corrugated filter medium 11. The amount of adhesive supplied during this application is adjusted by the adhesive supply device.

Further, the adhesive applying device 4 is arranged near the lower end surface of the rotary adhesive drum 52 of the heating adhesive device 5 so as to face the slit 46 (see FIGS. 8 and 9). The adhesive application device 4 is moved up and down by a cylinder (not shown), and the gap between the top surface of the slit 46 and the top 111 of the corrugated filter medium 11 is adjusted to 0.2 to 0.5 mm. The width of the slit 46 is 0.2 to 1.0 mm. In addition, the adhesive application device 4 of this example is provided with slits 46 at two positions, and the adhesive is not applied to the central portion of the top 111 in the width direction.

In this embodiment, the adhesive is jet-coated by the slit 46 from the adhesive supply device through the adhesive reservoir 452. Therefore, the amount of adhesive supplied can be adjusted according to the amount applied, and the adhesive can be applied reliably without waste. Further, the adhesive is once stored in the adhesive reservoir, and only the necessary amount is jetted from the slit 46. Therefore, even if the adhesive is less likely to be contacted with air and is easily oxidized by a general roll coater, the adhesive can be applied without being oxidized and deteriorated. In addition, the same effect as that of the first embodiment can be obtained.
