And a fourth horizontal line 110d extending to the second side edge 107b while being close to.

Also, the first and second straight horizontal joints which are opposed to and adjacent to each other via a second boundary dividing line 109c2 located at the rear end opposite to the first boundary dividing line 109c1 located at the front end of the first processing area S1. The first where the lines 109b, 109b are located
In the second processing areas S1 and S2, a cutting line 111a is formed at a position corresponding to the upper end of the completed half body with sleeves 2A and 2B opposite to the sleeve 3. FIG.
The reference numeral 130 indicates a cut piece of the first and second webs 1A, 1B by the cut line 111a. The first and second substantially L-shaped joint lines A1, A2 are the first and second straight horizontal joint lines 109a, Simultaneously with or after the application of 109b, substantially Z-shaped cutting line B and cutting line 111a
Is preferably performed after or simultaneously with the application of the first and second substantially L-shaped joint lines A1 and A2.

In the second processing area S2, the first processing area S
1 is the boundary line between the first and second machining areas S1 and S2 or the first and second
Each joining line and cutting line are provided so as to be symmetrical with respect to the second boundary dividing line 109c2 of the webs 1A and 1B.

The size between 09a and 109b is the above-mentioned upper garment 1 to be obtained.
Can be appropriately selected so as to be adaptable to the wearer's body and favorite design.

The manufacturing process of the upper garment 1 includes the first and second webs 1A and 1B in the first and second processing zones S1 and S2.
First and second by boundary dividing lines 109c1 and 109c2
Subsequent to the cutting process of the webs 1A and 1B, the process is shifted to a process of forming the body 2 by joining the sleeved left and right half bodies 2A and 2B to each other. In FIGS. 5 and 7 showing this step, for convenience, each half body 2A,
2B is indicated by A, B, C, and D.

First, the half body A with sleeves moves straight on the transfer line L1 and moves to the transfer means L2 located downstream of the transfer means L1, and then the transfer means L orthogonal to the transfer means L2.
Go to 3 and wait here for the arrival of the half body with sleeves D,
Next, after the sleeved half body B moves straight on the transfer means L1 and moves to the transfer means L2, it further moves to the transfer means L4 orthogonal to the transfer means L2, where it waits for the arrival of the sleeved half body C. Next, the sleeved half body D moves straight on the transfer means L1 and moves to the transfer means L3 via L2 so that the sleeved half body A and the inner edges thereof are closely aligned, and then the sleeved half body C Travels straight through the transfer means L1 and moves to the transfer means L4 via L2 so that the sleeved half body B and the inner edges thereof are aligned so as to face each other. The aligned pair of sleeved half bodies A and D move to the transfer means L5 via the transfer means L3. On the other hand, the aligned pair of sleeved half bodies B and C move to the transfer means L6 via the transfer means L4. Transfer means L
A pair of sleeved half-body A, D; B, C moved to 5, 6
Are lifted upward while being attracted to each other by the joining means 18a and 18b, and are drawn inward to be joined in a state where the inner edges 107a and 107b are overlapped with each other in a palm shape, and the inner edges 112 are overlapped with each other. (See FIG. 8). However, the inner edge 107
Unlike the illustration, a and 107b may be joined by overlapping each other vertically.

The transfer means L1 and the transfer means L2, and the transfer means L2 and the transfer means L3 and L4 run so that the aligned pair of sleeved half bodies A, D; B and C do not deviate from each other. The speed is adjusted to synchronize. Also,
Movement of each pair of sleeved half-body A, D; B, C from transfer means L2 to transfer means L3, L4, and movement of a pair of sleeved half-body A, D from transfer means L3 to transfer means L5. The movement of the pair of sleeved half bodies B and C from the moving means L4 to the moving means L6 is performed by suction means (not shown) which moves while holding the sleeved half body with suction.

According to the movement and alignment of the sleeved half bodies A, B, C, and D, it is not necessary to invert the sleeved half bodies to align the sleeved half bodies. It can be said that this is the form. However, the embodiment is merely an example in the present invention. In the present invention, the half body with sleeves A,
It is to be understood that any of B; C, D could be reversed for said alignment and practiced without excluding such embodiments.

As a material for the first and second webs 1A and 1B, for example, a nonwoven fabric obtained by a known nonwoven fabric manufacturing method such as spunlace, thermal bond, melt blown, chemical bond, and air through can be used. In addition, as the material of the nonwoven fabric, polyolefin,
Various known fibers such as polyester and polyamide can be used. Depending on the use of the upper garment 1 to be obtained, the nonwoven fabric is subjected to a process for imparting known required performances, for example, water pressure resistance, moisture permeability, tear strength, bulkiness, flexibility, stretchability, and the like. Can also.

[0031]

According to the method for manufacturing a disposable garment according to the present invention, a pair of straight horizontal joint lines and a pair of substantially L-shaped joint lines are formed in the processing regions of the first and second webs which are overlapped with each other. A garment as a body with sleeves can be easily manufactured by simply applying one substantially Z-shaped cutting line. In addition, a garment in which the body and the sleeve are continuously continuous can be manufactured from a relatively small width web. Furthermore, the angle to the body of the sleeve and the shape of the side edge of the body are arbitrarily formed to improve the fit and design of the wearer's body, and to produce garments that use garment materials without waste at high speed and at low cost. be able to.
