A pair of 3s are placed. The ultrasonic welding machine 22, 2
3, the unfinished clothes cover (see FIG. 3) is carried by the conveyor 24, and the unwelded cut edges are covered with continuous tapes 18 and 19 from both the top and bottom sides, and then welded and joined. ing.

Further, in the feeding direction of the ultrasonic welding machines 22 and 23, male hooking machines 25 and 26 and female hooking machines 27 and 28 are arranged, and male and female hooking machines are arranged near each cut of the clothes cover. The hooks of each are to be nailed down. that time,
A reversing conveyor 29 for reversing the front and back of the clothes cover is disposed between the male hooking machines 25, 26 and the female hooking machines 27, 28.
If the clothing cover is moved straight forward as it is, the hooks will hit as shown in Figure 4, while if it is reversed and moved straight, the hooks will hit as shown in Figure 5.

In the first manufacturing line 2, a tape holder 31 for holding the continuous tape 30 in a roll is provided between the set roll 6 and the ultrasonic welding machines 8 and 9 for ultrasonic welding. Machine 32 is arranged. As shown in FIGS. 6 and 7, the ultrasonic welding machine 32 includes a slitter 35 consisting of a substantially cylindrical body 34 integrally attached to a shaft 33 that rotates in synchronization with the feeding of the continuous sheet 4. It is provided. The slitter 35 includes a plurality of sharp fusing blades 36 at the center of the main body 34 and welding blades 37 at both ends thereof.
The welding blades 37 extend in the radial direction at regular intervals along the circumferential direction, and the welding blades 37 extend at right angles to the fusing blades 36 . As a result, the continuous tape 30 is guided from the tape holder 31 to the center of the upper surface of the continuous sheet 4 via the positioning guide 38, and is welded and bonded so as to have a series of cuts a in the continuous sheet 4, as shown in FIG. be done. The cuts a are provided at intervals that can be easily torn with a fingertip or the like, and form an entrance to a clothing cover such as a suit.

In addition, 39 is a press for making a hole for hanging the clothes hanger, 40, 41, 42, 4
3 is a cutter for cutting the continuous tapes 18, 19. Further, 44, 45, and 46 are guide rolls, and 47, 48, 49, and 50 are positioning guides that guide the continuous tape.

Next, the operation of the above embodiment will be explained.

When the device is operated, the set roll 6 and the tape holder 3 are rotated in synchronization with the rotation of the set roll 6.
rotates, and the continuous sheet 4 and continuous tape 30 are unwound from the set roll 6 and tape holder 31, respectively. The continuous tape 30 is
Together with the continuous sheet 4, it is guided to an ultrasonic welding machine 32 for fusing, and cut at the center of the upper surface of the continuous sheet 4 by a fusing blade 36 of a slitter 35 so as to have cuts a at regular intervals along the feeding direction. At the same time, the welding blade 37 continuously welds and joins the sheet onto the continuous sheet 4.

On the other hand, the continuous sheet 5, together with the continuous sheet 4, is guided from the set roll 7 via the guide roller 45 to the ultrasonic welding machines 8, 9 for peripheral edge welding in a mutually overlapping state. In the ultrasonic welding machines 8, 9, positioning guides 47,
The continuous tapes 10 and 11 guided through 48 are welded and bonded in a superposed state from both upper and lower surfaces. As a result, the two continuous sheets 4 and 5 are processed into a continuous cylindrical shape in the feeding direction.

After the welding by the ultrasonic welding machines 8 and 9 is completed, the continuous sheets 4 and 5 are attached to the pinch rollers 14 and 1.
5 and step rollers 16, the paper is sent to a cutter 17 at a constant feed speed, and is cut at regular intervals perpendicular to the feed direction. As a result, the continuous sheets 4 and 5 are sent to the second production line 3 as unfinished clothes covers as shown in FIG.

This unfinished clothes cover is guided by a conveyor 24 to ultrasonic welding machines 22, 23 for peripheral welding, and the unwelded cut edges are welded to continuous tapes 18, 1.
9, the upper and lower surfaces are continuously covered and welded and joined. As a result, continuous sheets 4, 5
The peripheral edges of the tapes are all welded together and bordered by continuous tapes 10, 11, 18, and 19.

After that, this clothes cover is made of continuous tape 10,
Cut 11, 18, 19 into 40, 41, 42, 4
3, the products are separated into parts by the reversing conveyor 2 by the hooking machines 25, 26, 27, and 28.
Male and female hooks are nailed through 9. Furthermore, a hole is made by the press 39 to allow a hanger to be hung on the clothes, thereby completing the series of manufacturing of the clothes cover.

Therefore, according to the embodiment described above, the continuous sheets 4, 5 have their peripheral edges passed through the first and second production lines 2, 3, and then passed through the ultrasonic welding machine 8 for peripheral edge welding.
In addition to being continuously welded and joined by 9, 22, and 23, one continuous sheet 4 of the pair of continuous sheets 4 and 5 is used to form an entrance/exit for a suit, etc.
In addition, the ultrasonic welding machine 32 for fusing cuts the continuous tape 30 while leaving welding marks along the feeding direction and making cuts a at regular intervals, so no manual work is required and automatic continuous operation is possible. This makes it possible to improve productivity, reduce costs, improve homogeneity and dimensional accuracy, and obtain reliable products.

Furthermore, the slitter 35 is equipped with welding blades 37 at both ends of the welding blade 36, and at the same time as the welding blade 36 is fused, the continuous tape 30 is firmly pressed onto the continuous sheet 4 and welded while leaving welding marks, so strong strength can be obtained. . Furthermore, by changing the welding blade 37 into various shapes and interposing the continuous tape 30, various patterns can be drawn on the surface of the continuous tape 30 welded to the continuous sheet 4, increasing the decorative effect. , product design improves. In addition, even when the continuous tape 30 is not used, the welding blade 35
Since it is possible to create a welding mark at the same time as the melting and welding the material firmly, there is no possibility of so-called bulges or fraying from the melted part.

In addition, for materials that are difficult to flop or fray, such as non-woven fabrics and synthetic resin films, the welding blade may be eliminated in the slitting process using the fusing blade 36, as shown in FIGS. Cuts can be made at regular intervals without causing any deterioration in the quality.

(Effects of the Invention) As described above, according to the present invention, a pair of continuous sheets are guided from a set roll to an ultrasonic welding machine for peripheral welding in a superimposed state, and the continuous sheets are continuously welded by the ultrasonic welding machine for peripheral welding. In addition to welding and joining the corresponding peripheral edges with tape, one of the pair of continuous sheets is welded at regular intervals using an ultrasonic welding machine for fusing to form an entrance/exit for the dressmaking product. Since the cuts are made in the 2nd direction, manual operation is not required at all, automatic continuous operation is possible, productivity is improved, costs are reduced, and uniformity and dimensional accuracy are good, making it reliable. You can get a product with good quality. Further, in the ultrasonic welding machine for fusing,
When welding blades are provided on both sides of the fusing blade, it is possible to make cuts in the continuous sheet and also to make welding marks at the same time, thereby providing strong strength and improving the decorative effect.
