  • Publication number: 20200024779
    Abstract: An apparatus and method for applying a first web to a base web in a nonlinear pattern as the base web is advanced in a machine direction in contact with a back-up roller are disclosed. The apparatus can include a guide roller and a guide roller translations system. The guide roller can be configured to define a nip with the back-up roller. The guide roller translation system can be configured to allow the guide roller to move with respect to the back-up roller to control the position of the nip to allow the first web to be applied to the base web in the non-linear pattern in the machine direction.

  • Publication number: 20200016010
    Abstract: An applicator for and method of guiding a first web to a base web in a nonlinear pattern as the base web is advanced in a machine direction are disclosed. The applicator can include a support structure, a cantilever arm, a guide roller, and a connecting link. The cantilever arm can be supported by the support structure and moveable through a range of motion relative to the support structure in a cross machine direction. The guide roller can guide the first web onto the base web and can be pivotally mounted on the cantilever arm for pivotal movement of the guide roller with respect to the cantilever arm. The connecting link can be operatively coupled to the guide roller. Pivotal movement of the guide roller can be dependent on movement of the connecting link. Positioning of the guide roller in the cross machine direction can be dependent on movement of the cantilever arm.

  • Publication number: 20190240920
    Abstract: A method of bonding a first web of material to a second web of material to form a composite material is disclosed herein. First, a first web of material and a second web of material moving in a machine direction is provided. The webs of material pass over a first energy application device extending transverse in the cross-machine direction. The first energy application device includes a primary bonding pattern and a secondary bonding pattern. The primary bonding pattern in combination with the secondary bonding pattern extends continuously across the first energy application device in the cross-machine direction. In addition, a second energy application device is provided. The second energy application device is moved in the cross-machine direction, and thereby extending the second energy application device over the first energy application device and operating the first and second energy application devices in combination to bond a composite web.

  • Patent number: 7000260
    Abstract: A disposable garment, subassemblies of the garment, and apparatus and methods for making the garment and subassemblies. The garment has elasticized leg and waist openings. The apparatus and methods of the invention facilitate assembling leg elastics and crotch elastics into the garment subassemblies, with the leg elastics extending across the width of the garment, and the crotch elastics extending along the length of the garment, while assembling a series of the garment subassemblies in a continuous web structure at a constant, or relatively constant, continuous and efficient speed. The leg elastics are installed across the crotch. The resulting garment is free from resilient tension across the crotch when the crotch portion is extended across the width of the garment.

  • Patent number: 6899780
    Abstract: This invention pertains to processing continuous webs such as paper, film, composites, and the like, in dynamic continuous processing operations. More particularly, it relates to transferring discrete parts to a continuous web, whether paper, film, composite, or the like. Specifically, the invention relates to methods and apparatus for taking discrete parts from a source in a taking zone, optionally taking the discrete parts as components of a continuous web, onto a transport head on a transfer assembly, severing the discrete parts from the continuous web if received as part of a continuous web, rotating the transfer assembly about a first axis and correspondingly rotating the transport head about a second axis radial to the first axis, to thereby present the discrete parts to a receiver in a transfer zone, and transferring the discrete parts to the receiver in the transfer zone.

  • Patent number: 6856850
    Abstract: This invention pertains to processing continuous webs such as paper, film, composites, and the like, in dynamic continuous processing operations. More particularly, it relates to accumulating limited lengths of such continuous webs and to controlling tension in such continuous webs during the processing operation. Both tension control and limited accumulations are achieved in festoon systems by connecting corresponding movably mounted festoon rolls to an actuator, sensing parameters such as position, tension, velocity, and acceleration related to the web and the festoon, and providing active force commands, in response to the sensed variables, to cause translational movement, generally including a target acceleration, in the movably mounted festoon rolls to control tension in the web while providing limited accumulation of a length of the web. The festoon control system can be used to attenuate tension disturbances, in the alternative to create controlled tension disturbances.

  • Publication number: 20030196253
    Abstract: This invention pertains to a three dimensional disposable garment, subassemblies of the garment, and apparatus and methods for making the garment and subassemblies. The garment is designed to hold a primary absorbent sanitary pad. The garment may have elasticized leg and waist openings and be stretchable about the hip and stomach regions of a user. The garment provides backup protection to control egress of fluids that leak or seep around or through the primary sanitary pad. The garment includes a secondary absorbent positioned in the crotch area and extending into the body of the disposable garment, front and back, and preferably over the leg elastics to trap, inside the garment, leakage from the primary absorbent, and to prevent strike through onto e.g. outer clothing and bed linen.

    Abstract: This invention pertains to processing continuous webs such as paper, film, composites, and the like, in dynamic continuous processing operations. More particularly, it relates to controlling tension in such continuous webs during the processing operation. Tension is controlled in a dancer control system by connecting a corresponding dancer roll to an actuator apparatus or the like, sensing variables such as position, tension, velocity, and acceleration parameters related to the web and the dancer roll, and providing active force commands, in response to the sensed variables, to cause translational movement, generally including a target acceleration, in the dancer roll to control tension disturbances in the web. In some applications of the invention, the dancer control system is used to attenuate tension disturbances. In other applications of the invention, the dancer control system is used to create tension disturbances.
