Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for manufacturing a disposable garment that can be easily worn by doctors, nurses, other workers, examinees in hospitals, inspectors of health examination samples in other facilities, various kinds of experimenters, and the like.
[0002]
[Prior art]
Japanese Patent Application Laid-Open No. 46-5123 forms two constant-width webs that form one front half body member that bisects the upper garment in the width direction and the other front half body member on the production line. While the two webs having a constant width are opposed to each other in the width direction and continuously moved in the length direction, the one and the other second half body members are joined to each other at the inner edges facing each other. A technique for continuously producing a disposable upper garment by a machine by forming a member and attaching a pair of sleeve members formed in advance to the body member on the production line is disclosed.
[0003]
Japanese Patent Laid-Open No. 47-9270 discloses that in a production line, two webs having the same width are overlapped with each other and continuously moved in the length direction, and the body and sleeves are sequentially formed on the two webs. The joint garment is continuously machined by cutting the two webs along the outer edge of the joint line by applying a joint line corresponding to the outer contour edge of the continuous upper garment without using a seam. The technology to produce automatically.
[0004]
In Japanese Patent Publication No. 51-34337, the sleeve member is formed on the production line while the wide body member web and the wide sleeve member web are superimposed on the upper surface and continuously moved in the length direction. A technique for continuously forming a disposable garment by a machine by forming a pair of sleeve members from a web for a body, forming a body member from the web for a body member, and joining the sleeve member and the body member Is disclosed.
[0005]
[Problems to be solved by the invention]
In the technique disclosed in Japanese Patent Application Laid-Open No. 46-5123, a total of four continuous webs are required to form the body member in order to form one of the two and the other front and rear body members, respectively. It is necessary to form a pair of sleeve members in advance separately from the body member.
[0006]
In the technique disclosed in Japanese Patent Application Laid-Open No. 47-9270, a pair of sleeves forms an upper garment extending obliquely outward from both shoulders of the body, and two continuous sheets for forming the upper garment are formed. As the web, a wide web corresponding to the dimension between the ends of the pair of sleeves is required, and the two webs in the outer region of the outer contour edge of the upper garment are cut out, which is economically wasteful.
[0007]
In the technique disclosed in Japanese Patent Publication No. 51-34337, it is necessary to form a pair of sleeve members in advance separately from the body member and attach them to the body member.
[0008]
Therefore, it cannot be said that each of the known techniques is a suitable method for mechanically mass-producing the upper garment at low cost.
[0009]
According to the present invention, a pair of sleeves can be connected to the body without a seam, and a joining or cutting pattern that can improve the fit and design of the wearer's body can be arbitrarily selected. An object of the present invention is to provide a method suitable for continuously mass-producing a disposable garment on a production line at a low cost.

It consists of a second vertical line 110b extending gradually smaller toward the boundary dividing line c1. The first and second webs 1A and 1B are joined by the joining line.
[0023]
The substantially Z-shaped cutting line B corresponds to the first and second horizontal lines 108a and 108b of the first and second substantially L-shaped joining lines A1 and A2 at the same time or after the joining line is formed in the first processing area S1. A third horizontal line 108c extending in the horizontal direction therebetween, a third vertical line 110c connected to one end of the first horizontal line 108c and extending close to the first vertical line 110a of the first substantially L-shaped joining line A1 and extending to the boundary dividing line 109c2. A fourth vertical line 110d is connected to the other end of the third horizontal line 108c and extends from the other end to the boundary dividing line 109c1 along the second vertical line 110b of the second substantially L-shaped joining line A2. . By the cutting line, the half bodies 2A, 2B with sleeves 3 are formed from the first and second webs 1A, 1B.
[0024]
Further, a cut line 111a is provided at a position corresponding to the center of the upper end between the sleeves 3 in the half bodies 2A and 2B with the sleeve 3. Reference numeral 130 in FIG. 5 indicates cut pieces of the first and second webs 1A and 1B along the cut line 111a.
[0025]
The first and second substantially L-shaped joining lines A1 and A2 are substantially the same as the first and second straight vertical joining lines 109a and 109b or after the application, and the substantially Z-shaped cutting line B and the cutting line 111a are It is preferable that the first and second substantially L-shaped joining lines A1 and A2 are applied or simultaneously with the application. Such a joining line and a cutting line are sequentially applied from the downstream first machining area S1 to the upstream third machining area S3.
[0026]

[0027]
In the manufacturing process of the upper garment 1, following the cutting process of the first and second webs 1 </ b> A and 1 </ b> B by the dividing boundary lines of the webs 1 </ b> A and 1 </ b> B, the half bodies 2 </ b> A and 2 </ b> B with sleeves 3 are joined to each other. It moves to the process for forming.
[0028]
5 and 7, each pair of the half bodies 2A, 2B with the sleeve 3 is indicated by A, B, C, D for convenience. First, the pair of half-body A and D with sleeves moves straight on the transfer line L1, moves to the transfer means L2 located downstream of the transfer means L1, and then moves to the transfer means L3 orthogonal to the transfer means L2. On the other hand, the pair of half-body bodies with sleeves B and C go straight through the transfer means L1 and move to the transfer means L2, and then move to the transfer means L4 orthogonal to the transfer means L2. Each pair of sleeved half bodies A, D; B, C moved to the transfer means L3, L4 is moved as it is, and the sleeved half bodies 2A, 2B and their inner edges 117, 117 are joined to the joining means 18a, While being adsorbed by 18b, they are lifted upward while being attracted inward and joined together in the form of a palm, and the inner edges 112 are superimposed on each other (see FIG. 8). However, the inner edges 117 and 117 may be joined so as to overlap each other, unlike the illustrated case.
[0029]
The travel speed of the transport means L1 and the transport means L2 and the transport means L2 and the transport means L3 and L4 are adjusted appropriately for the movement. Further, the movement of the pair of sleeved half bodies A, D; B, C from the transfer means L2 to the transfer means L3, L4 is not shown, but is performed by suction means that move by adsorbing and holding them. .
[0030]
As a material of 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, air through, or the like can be used. Moreover, as a material of the nonwoven fabric, various known fibers such as polyolefin, polyester, and polyamide can be used. Depending on the application of the upper garment 1 to be obtained, the nonwoven fabric is subjected to a treatment for imparting known required performance such as water pressure resistance, moisture permeability, tear strength, bulkiness, flexibility, stretchability, etc. You can also.
