Definitions

  • This invention relates to a process for making a disposable upper garment.
  • a process for making disposable upper garment comprising steps of:
  • said step (d) of inverting the relative position of said first and second front body sheets comprises a step of feeding narrow belt members made of a nonwoven fabric successively pair by pair, each of said belt members having longitudinally opposite ends and transversely opposite side edges, placing said belt members upon the respective upper surfaces of said first and second front body sheets so that, at a predetermined distance ahead of said sleeve members as viewed forward in said longitudinal direction, the transversely opposite side edges of said belt member extending in parallel to the transversely opposite outer side edges of said first and second front body sheets, and bonding respective rear ends of said belt members to the respective upper surfaces of said first and second front body sheets.
  • Figs. 1 and 2 are schematic diagrams illustrating, by way of example, sequential steps of a process for making a disposable upper garment of this invention in side views (1) and in plan views (2).
  • Fig. 1 illustrates the first step (a) - the fourth step (d)
  • Fig. 2 illustrates the fifth step (e) - the seventh step (g) following the steps illustrated in Fig. 1.
  • a front body sheet 2 a rear body sheet 3, a pair of sleeve members 4, 4 and a pair of belts 5, 5 are assembled to make an upper garment 1.
  • the front body sheet 2 is made of a nonwoven fabric having a given width and defined by upper and lower surfaces A, B, right and left side edges 2a, 2b extending in the longitudinal direction and a center line Y1 extending in the longitudinal direction to bisect a width between the right and left side edges 2a, 2b.
  • the rear body sheet 3 is made of a nonwoven fabric having a width larger than the width of the front body sheet 3 and defined by upper and lower surfaces A, B, right and left side edges 3a, 3b and a center line Y3 extending in the longitudinal direction to bisect a width between the right and left side edges 3a, 3b.
  • the sleeve member 4 is made of a nonwoven fabric sheet folded onto itself and bonded together along its transversely opposite side edges placed upon each other, and has wrist-opening 4a, 4b defined by longitudinally opposite ends 4a, 4b and a center line Y2 bisecting a width between these ends 4a, 4b.
  • the front and rear body sheets 2, 3 travel through the respective steps as nip rolls are driven by driving means.
  • the sleeve member 4 and the belt members 5 travel through the respective steps as nip rolls, suction drums or endless conveyor belts are driven by driving means.
  • the front and rear body sheets 2, 3, the sleeve member 4 and the belt members 5, 5 are fed at the same rate.
  • the first step (a) is a step of forming the front body sheet 2 with a pair of cutouts 6 destined to form a neckline.
  • the front body sheet 2 stored on a delivery roll 100 is continuously fed forward in the longitudinal direction as a nip roll 101 rotates.
  • a pair of regions are cut off from the front body sheet 2 by a cutter 102 placed at the downstream of the nip roll 101 so that the cutout 6 obtained by this step of cutting off may describe a convex curve extending from the right and left side edges 2a, 2b toward the center line Y1.
  • the cutouts 6 identical to each other in shape as well as in size.
  • the cutouts 6 are symmetric about the center line Y1.
  • the second step is a step (b) of bonding the sleeve member 4 to the upper surface A of the front body sheet 2.
  • a plurality of the sleeve members 4 stored on a delivery roll 103 provided with suction means are fed forward in the longitudinal direction one by one at predetermined intervals in such a manner that the transversely opposite side edges 4c, 4d connecting the longitudinal opposite ends 4a, 4b of the sleeve member 4 extend in parallel to the transversely opposite side edges 2a, 2b of the front body sheet 2.
  • the sleeve member 4 is 90° turned by turning over means 104 placed at the downstream of the delivery roll 103 so that the side edges 4c, 4d of the sleeve member 4 intersect the side edges 2a, 2b of the front body sheet 2 at right angle. Then the sleeve member 4 is held on a peripheral surface of a suction drum 106 placed at the downstream of the turning over means 104.
  • the front body sheet 2 is coated in a first bonding zones S1 on the upper surface A with adhesive by an adhesive coating device 105 placed at the upstream of the suction drum 106.
  • the first bonding zones S1 lie on both sides of the center line Y1 slightly ahead of the neckline 6 and extend in parallel to the center line Y1.
  • Each bonding zone S1 is dimensioned to be substantially a half of a circumferential dimension of the sleeve member 4.
  • the front body sheet 2 having been coated with the adhesive then passes between the contacting surfaces of the drum 106 and the nip roll 107.
  • the single sleeve member 4 moving together with the peripheral surface of the drum 106 is controlled so that the center line Y2 of the sleeve member 4 coincides with the center line Y1 of the front body sheet 2 and the sleeve member 4 is exactly placed upon the bonding zones S1.
  • the sleeve member 4 passes between the contacting surfaces of the drum 106 and the roll 107, the sleeve member 4 is bonded to the front body sheet 2 by means of the adhesive.
  • a transverse dimension of the sleeve member 4 is larger than that of the front body sheet 2 and the longitudinally opposite ends 4a, 4b of the sleeve member 4 extend outward beyond the transversely opposite side edges 2a, 2b of the front body sheet 2.
  • the third step (c) is a step of dividing the front body sheet 2 in a first front body sheet 2A and a second front body sheet 2B.
  • the front body sheet 2 and the sleeve member 4 are cut along their center lines Y1, Y2, respectively, by a cutter 108.
  • the front body sheet 2 is divided in the first front body sheet 2A lying on the right side of the center lines Y1, Y2 and the second front body sheet 2B lying on the left side of the center lines Y1, Y2 as viewed in the longitudinal direction.
  • the fourth step (d) is a step of inverting the relative position of the first front body sheet 2A and the second front body sheet 2B.
  • an inverter 109 inverts the relative position of the first and second front body sheets 2A, 2B so that the first front body sheet 2A may lie on the left side and the second front body sheet 2B may lie on the right side as viewed forward in the longitudinal direction.
  • Such inversion of the relative position may be achieved by simultaneously moving these sheets 2A, 2B to their new positions of one of these two sheets 2A, 2B may be moved to its new position opposed to the other sheet.
  • the cutouts 6 of these sheets 2A, 2B are opposed to each other and placed side by side in a relationship of plane symmetry.
  • the side edges 2a, 2b which have been the transversely opposite side edges 2a, 2b of the undivided front body sheet 2 now define side edges 2a, 2b of the first and second front body sheets 2A, 2B closely adjacent and opposed to each other.
  • the longitudinally opposite ends 4a, 4b of the sleeve member 4 is now placed upon each other. Laterally inversion of the relative position of the first and second front body sheets 2A, 2B enables the sleeve member 4 longer than the width of the front body sheet 2 to be attached to the jacket 1 without being restricted by the width of the front body sheet 2.
  • the fourth step (d) includes a step of bonding the paired belt members 5, 5 to the upper surface A of the first and second front body sheets 2A, 2B, respectively. While the diagram illustrates the belt members 5, 5 to be bonded to the upper surface A of the first and second front body sheets 2A, 2B after the relative position of these sheets 2A, 2B have been inverted, it is also possible to bond the belt members 5, 5 to the first and second front body sheets 2A, 2B before the relative position of these two sheets 2A, 2B are inverted.
  • Each of the belt members 5, 5 is a narrow rectangular strip made of nonwoven fabric and defined by transversely opposite side edges 5a, 5b and longitudinally opposite ends 5c, 5d.
  • the belt members 5 are fed forward pair by pair at predetermined intervals from a delivery roll 110 on which a plurality of the belt members 5 are stored and including suction means in the longitudinal direction.
  • Each pair of the belt members 5, 5 are coated on their rear ends with adhesive by an adhesive coating device 111 interposed between said delivery roll 110 and a suction drum 112. These belt members 5, 5 are then hold on a peripheral surface of said drum 112.
  • each of the paired belt members 5, 5 has its transversely opposite side edges 5a, 5b extending in parallel to the transversely opposite outer side edges 2c, 2d and lie at a predetermined distance ahead of the sleeve member 4 as viewed in the longitudinal direction. Passing between the contacting surfaces of the drum 112 and the roll 113, these belt members 5, 5 are bonded to the first and second front body sheets 2A, 2B, respectively, by means of adhesive.
  • the fifth step (e) is a step of bonding the first and second front body sheets 2A, 2B to the rear body sheet 3 in second bonding zones S2.
  • the rear body sheet 3 stored on a delivery roll 114 is continuously fed forward in the longitudinal direction as a nip roll 116 rotates.
  • An adhesive coating device 115 interposed between the delivery roll 114 and the nip roll 116 coats the upper surface A of the rear body sheet 3 with adhesive along transversely opposite side edges 3a, 3b as well as along portions of respective lines transversely extending between the opposite side edges 3a, 3b of the rear body sheet 3.
  • the first and second front body sheets 2A, 2B are placed upon the rear body sheet 3 with the transversely opposite outer side edges 2c, 2d of the first and second front body sheets 2A, 2B coinciding with the center line Y3 of the rear body sheet 3.
  • the respective lower surfaces B of the first and second front body sheets 2A, 2B are bonded to the upper surface A of the rear body sheet 3 by means of adhesive in the second bonding zones S2 extending transversely of the first and second front body sheets 2A, 2B except the cutouts 6 destined to define the neck-opening.
  • the sixth step (f) is a step of bonding the first and second front body sheets 2A, 2B, the sleeve members 4, 4 and the rear body sheet 3 together in third bonding zones S3.
  • a folding device 118 folds the transversely opposite side edges of the rear body sheet 3 onto the respective upper surfaces A of the first and second front body sheets 2A, 2B. In this manner, the first and second front body sheets 2A, 2B, the sleeve members 4, 4 and the rear body sheet 3 are bonded together in the third bonding zones S3 extending in the longitudinal direction along the transversely opposite side edges 3a, 3b of the rear body sheet 3.
  • the seventh step (g) is a step of cutting the first and second front body sheets 2A, 2B and the rear body sheet 3.
  • a cutter 119 cuts these sheets 2A, 2B, 3 transversely of them and, at a predetermined distance ahead of the belt members 5, 5 as viewed in the longitudinal direction, the same cutter 119 cuts these sheet 2A, 2B, 3 transversely of them.
  • Fig. 3 is a perspective view showing the disposable jacket 1 made using the process as the sleeve members 4 have been laterally spread.
  • the upper garment 1 comprises the first and second front body sheets 2A, 2B and the rear body sheet 3 bonded together, a pair of the sleeve members 4, 4 attached to the upper ends of these sheets 2A, 2B, 3 and extending outward from these sheets 2A, 2B, 3, and a pair of belt members 5, 5 partially bonded to the first and second front body sheets 2A, 2B in their middle zones.
  • the upper garment 1 has the neckline defined by a pair of the cutouts 6 in the middle of its upper end, a hemline defined by its lower end and a front slit-like opening 8 extending between the upper and lower ends of the upper garment 1.
  • the upper ends of the front and rear body sheets 2, 3 except the cutouts 6 of the neckline define a pair of shoulders. Bonding of the front and rear body sheets 2, 3, the sleeve members 4 and the belt members 5 may be carried out using suitable adhesive agent such as hot melt adhesive or suitable sealing technique such as heat- or ultrasonic-sealing. Bonding of these sheets may be achieved in continuous or intermittent mode. Cutting of the sheets 2, 3 may be carried out not only using a cutting die but also using the other cutting technique utilizing laser rays or ultrasonic wave.
  • the front and rear body sheets 2, 3, the sleeve members 4, 4 and the belt members 5, 5 are preferably made of a nonwoven fabric formed by thermoplastic fibers such as a spun bond nonwoven fabric or a melt blown nonwoven fabric.
  • a nonwoven fabric formed by thermoplastic fibers such as a spun bond nonwoven fabric or a melt blown nonwoven fabric.
  • particularly preferable stock material for these members includes a spun bond, a point bond or melt blown nonwoven fabric having a basis weight of 50 - 100g/m 2 each containing dependently rayon, nylon, pulp or a mixture thereof.
  • Useful stock material for these sheets further includes a nonwoven fabric made porous to improve its moisture-permeability, a nonwoven fabric embossed to generate irregularity and thereby to improve its cushioning property or nonwoven fabric treated to have an elasticity.
  • the production line as has been described heretofore utilizes an optical sensor comprising an emitting optics and a receiving optics, a rotary speed sensor adapted to measure a rotary speed of the rolls, a control device electrically connected to these sensors, and movable devices and a driving device also electrically connected to said control device to achieve proper positioning when the sheets 2A, 2B, 3 are placed one upon another or when the sheet 2 is placed upon the sleeve member 4, on one hand, and to control the rates at which said sheets 2, 3 and said sleeve member 4 should be fed.
  • a program to optimize a running environment for the production line is stored in a memory of said control device.
  • the process according to this invention enables the disposable upper garment to be made merely by bonding the body sheets, the sleeve members and the belt members together using adhesive or sealing technique and thereby enables a manufacturing cost to be remarkably reduced.
  • the process according to this invention adopts continuous running and automation of the sequential steps, instead of adopting discontinuous stitching steps of relay mode and thereby improves a productivity per unit time.
