    摘要: The present invention is to provide a method and an apparatus facilitating side edges of a web continuously running in a machine direction to be quickly corrected when these side edges are detected to be out of coincidence with a positions in a cross direction orthogonal to the machine direction. Roll means rotating about a shaft extending in a direction defined between a machine direction and a cross direction are put in contact with side edge of a web continuously running in the machine direction. The shaft is mounted on an arm adapted to rotate back-and-forth so that the shaft can swing in- and outward in the cross direction. Downstream of the roll means, the side edge is position-detected and the arm is made swing by a desired angle determined on the basis of a difference between the actual position and a desired position.

    摘要: Here is disclosed a method for efficiently attaching elastic members around leg-holes of a garment such as a disposable diaper or the like without any futile use of material.Elastic members 04A, 04B are fed and bonded onto a web so that the respective elastic members described curves like sine curves with summits and troughs of these curves defining together respective annular elastic areas 16 and thereby a base web is formed. Then the base web is severed into strips 17' bearing thereon the individual annular elastic areas and these strips 17' are intermittently bonded to a web 07 to form a composite web 19. A separate web is bonded onto a top surface of the composite web 19 to form a composite web 20. Finally, the composite web 20 is severed along center lines of the respective annular elastic areas 16 into individual garments.

    摘要: The present invention generally resides in method and apparatus for intermittently applying pieces of elastic band severed into a predetermined length onto a moving continuous web at predetermined positions. The apparatus comprising elastic band transfer means including a plurality of independently rotatable rotor elements coaxially supported in rotatable fashion and carrying on respective arc-shaped outer surfaces suction members wherein the respective rotor elements carrying the respective suction members are adapted to be rotated along common circumferential path and the respective rotor elements are coupled to a drive wheel eccentrically located relative to a rotational center of the respective rotor elements and adapted to be rotated at a constant speed by a rotatable slider crank mechanism; suction distributor means for the respective suction members, adapted to operate synchronously with rotation of the drive wheel; means to feed continuous elastic band tangentially to the circumferential path of the respective suction members; means intermittently cooperating with one of the respective suction members periodically advanced by the elastic band transfer means to a predetermined position to sever the continuous elastic band; and web feeding means located in opposition to an end position of transport of the severed piece of elastic band along the circumferential path so that the piece of elastic band may be effectively transferred onto the web. This apparatus may further comprise means by which at least one ends of the respective suction members are pivotally supported by the respective rotor elements in laterally displaceable fashion so that the one ends are laterally displaced as the respective rotor elements rotate.

    摘要: A moving web is folded at its predetermined length at its opposite side portions so that the opposite side portions are opposed to each other at a predetermined angle with its central portion. Then part of each of the opposite folded portions is outwardly folded. These foldings occur so that a first folding line and a second folding line being opposed to each other at each side of the web include portions in non-parallel relationship. Elastic bands are affixed onto the web along the second opposite folded portions longitudinally and substantially in parallel to each other. When the web is flattened from the folded condition, the paired elastic band affixed onto the web at its opposite sides each has a diagonal orientation symmetrically with respect to the direction in which the web moves.
