A pull-on garment (1) includes an outer cover (3) forming an outer surface of the garment, both lateral side edge portions of the outer cover in a front body portion F and both lateral side edge portions of the outer cover in a back body portion R being joined to each other to form a pair of side seals (4), a waist opening (8), and a pair of leg openings (9). Each of the side seals (4) includes a seal edge portion (41) where the edge portion (3F) of the outer cover (3) in the front body portion F and the edge portion of the outer cover (3) in the back body portion R are bonded to each other by a continuous linear fusion-bonded portion (40) extending in a longitudinal direction of the side seal (4). In a cross-section orthogonal to a direction in which the side seal (4) extends, the fusion-bonded portion (40) includes a narrow section (4F) which is formed at a middle portion thereof in the thickness direction Q and of which a width W along the inner-to-outer direction P is small. The narrow section (4F) includes broad sections (4A, 4B) which are provided on both sides of the narrow section (4F) in the thickness direction Q and of which the width W is larger than the width of the narrow section (4F).

An absorbent article having a plurality of granular particles placed between two liquid-permeable non-woven fabric sheets, the article including: a high-strength bonded portion formed in a loop-shaped pattern on the article such that the two non-woven fabric sheets are not separated even if the granular particles swell to thereby apply a separating force to a bonded position between the two non-woven fabric sheets; and a low-strength bonded portion formed in an inner area surrounded by the high-strength bonded portion such that the two non-woven fabric sheets are separated from each other at a bonded position when the granular particles swell to thereby apply a separating force to the bonded position between the two non-woven fabric sheets.

One surface of a belt-shaped sheet laminate (10) (continuous diaper strip), in which a plurality of sheets are laminated, is made to abut against a support member (21) having a light passage section (27) through which a laser beam (30) can pass, and the belt-shaped sheet laminate (10) which is in a pressurized state is irradiated, from the support member (21) side via the light passage section (27), with a laser beam (30) having a wavelength that is absorbed by the sheets constituting the sheet laminate (10) and that causes the sheets to generate heat, and thus, the belt-shaped sheet laminate (10) is cut and separated and, simultaneously, cut edge sections created, by the cutting/separation, in the plurality of sheets which are in the pressurized state are fusion-bonded together. Thus, sealed edge sections (4) (side seal sections) are formed by fusion-bonding the edge sections of the plurality of sheets in a state where the sheets' edge sections are superposed.

The present invention is to provide wearing articles adapted to be identified one from another in one and same articles on the basis of a pattern of seam arrays differentiated for every one of the wearing articles belonging to one and same articles and to provide a seam welder used to form the seam arrays. Front side edges 16a, 16a and rear side edges 16b, 16b of a diaper 1 are respectively joined by seam arrays 17 extending in a longitudinal direction Y and thereupon a waist-opening and a pair of leg-openings are formed. The diaper 1 comprises an inner sheet 18, an outer sheet 19 and a liquid-absorbent core 20 sandwiched between these inner and outer sheets 18, 19. The inner and outer sheets 18, 19 are formed of heat-sealable fibrous nonwoven fabrics containing thermoplastic synthetic resins. Each of the seam arrays 17 of the diaper 1 comprises a plurality of seam-welded regions 21 and a seam-nonwelded region 22 left behind in the seam array 17. In the seam array 17, the seam-welded regions arranged so as to be aligned in longitudinal and transverse directions, each substantially shaped in a square, partially lack at a position differentiated for every one of specified patterns.

Gewickelte Rohre (4) aus Kunststoff lassen sich in wirtschaftlicher Weise herstellen, indem man auf eine wandernde Unterlage (7) ein Polyurethan-Reaktionsgemisch (17) aufgibt und zu einem Band (16) aushärten läßt, welches direkt anschließend unter einem Wickelwinkel auf einen Zylinder (2) aufgewickelt wird, wobei die zwischen den Windungen (20) entstehende Fuge (22) ebenfalls mit einem Polyurethan-Reaktionsgemisch (23) ausgegossen wird, und wobei das als endloser Strang entstehende Rohr (4) laufend vom Zylinder (2) abgeführt wird.
摘要:
A fabric light control window covering in which fabric vanes 10a are adhesively bonded between two sheer fabric sheets 72,96 such that relative movement between the sheer fabric sheets in a direction perpendicular to the longitudinal direction of the fabric vanes changes the angle of the fabric vanes and, thus, controls the amount of light admitted through the shade. The vanes are bonded to the sheer fabric sheets in a manner which tends to bias the sheer fabric sheets together to the non-light admitting position. Also, disclosed are methods and apparatus for manufacturing the above window covering. The method features linear application of adhesive to the vane material which provides for a uniform appearance in the finished product. A heat setting process and apparatus is disclosed in which the bonded layers of sheer fabrics and vanes are fed between belts over hot and cool surfaces, under uniform tension and pressure. This provides for heat setting of the layers of the window covering to a uniform temperature-size relationship without inducing wrinkles or distortion into the fabric during heat setting.

A device including: a plurality of protruding portions of an anvil roll; an ultrasonically vibrating horn; a suction hole for drawing granular particles together with non-woven fabric sheets so as to carry the non-woven fabric sheets and to prevent the granular particles from being placed on the non-woven fabric sheets over the protruding portions; and a ridge extending along an outer circumference of the suction hole with a protruding height lower than a protruding height of the protruding portions.
