摘要： An apparatus and method for leveling a bonding device and anvil in an assembly via a closed-loop control system is provided. The assembly includes an anvil, a bonding device positioned adjacent the anvil and configured to interact with the anvil to form the bonds on the web, and an actuator that enables adjustment of an orientation between the bonding device and the anvil. The assembly also includes a closed-loop control system configured to control operation of the actuator, with the closed-loop control system configured to monitor an operational parameter of the assembly indicative of interaction of the bonding device with the anvil, determine whether the bonding device is parallel or substantially parallel with the anvil based on the operational parameter, and when the bonding device is not parallel or substantially parallel with the anvil, cause the actuator to adjust the orientation between the bonding device and the anvil.

摘要： Apparatus and methods are provided for folding discrete items such as diapers at high speeds. Discrete items are conveyed in a machine direction toward a pair of engaging members rotating in the machine direction and first carrying a top side of a leading edge of the discrete item with a first engaging member away from the conveyor, and then carrying a bottom side of the leading edge with a second engaging member back towards the conveyor. The diaper fold is created at a contact point with a folding finger which travels rotationally and straight in a fixed orientation about a travel path into and out of contact with the diaper.

摘要： A system and method for controlling the speed of both a continuous web and a bonding apparatus is provided in order to effectuate stronger bonds in the web. The bonding system includes a velocity changing device for increasing and decreasing a velocity of the web in a machine direction, an anvil and a corresponding ultrasonic horn that interact to form ultrasonic bonds on the web, and an anvil actuator configured to control a movement of the anvil. A control system is also included in the bonding system for controlling operation of the anvil actuator the velocity changing device, with the control system programmed to decrease a moving velocity of the web from a feed velocity to a bonding velocity as the web passes between the anvil and the ultrasonic horn and control movement of the anvil to synchronize the movement of the anvil with the moving velocity of the web.

摘要： An elastic composite structure includes a plurality of tensioned elastic threads positioned between first and second web layers. A pattern of laminating bonds fuse the first and second web layers together within a deactivated zone of the elastic composite structure. A cut end of a first portion of a tensioned elastic thread and a cut end of a second portion of the tensioned elastic thread are positioned on opposing ends of the deactivated zone. A pattern of anchoring bonds fuses the first and second web layers together within an anchored zone bounding opposing ends of the deactivated zone. The anchored zone includes a first plurality of bonds that anchor the first portion of the tensioned elastic thread to the first and second web layers and a second plurality of bonds arranged that anchor the second portion of the tensioned elastic thread to the first and second web layers.

摘要： A system and method for folding a discrete absorbent sanitary product includes conveying a product in a machine direction along a main conveyor, folding the product at a first folding station, and later folding the absorbent sanitary product at a second folding station. The product is folded at each of the first and second folding stations by engaging the product with a first drum and rotating the absorbent sanitary product in a first rotational direction, contacting the product with one or more folding fingers traveling in the machine direction, engaging the product with a rotating member adjacent to the first drum and downstream therefrom in the machine direction, the rotating member rotating in the first rotational direction, and folding the product over the one or more folding fingers via rotation of the rotating member in the first rotational direction.

摘要： An apparatus and method for manufacturing an elastic composite structure for an absorbent sanitary product includes at least one structure that guides web layers in a machine direction, an elastic thread combiner that combines a plurality of elastic threads to form a combined elastic thread assembly, and a bonding unit. The bonding unit bonds the web layers together via a bond pattern that includes bond lines that each have at least one pair of adjacent bonds, which anchor the combined elastic thread assembly within a passage defined by a pair of adjacent bonds in each of the plurality of bond lines. The passage is narrower than the combined elastic thread assembly in a non-tensioned state and wider than one of the plurality of elastic threads in a non-tensioned state.

摘要： A web splicing apparatus is disclosed that includes a web unwinding unit configured to hold a running web material roll and a new web material roll and to unwind webbing from the running web material roll and a web splicing unit operable with the web unwinding unit to selectively splice the webbing of the running web material roll with webbing of the new web material roll. The web splicing unit further includes a cutting assembly configured to selectively sever the webbing of the running web material roll, a web deflection device, an actuator system configured to linearly translate the web deflection device in a first direction and a second direction opposite the first direction, and a locking mechanism operable in a locked state and an unlocked state to selectively prohibit and enable movement of the web deflection device in the first direction and the second direction.

摘要： The present invention provides a method and apparatus for increasing the number of articles processed. over a distance traveled in the machine direction of an assembly line. In particular, the orientation of the long dimension of the article is provided transverse to the machine direction, thus process rug the articles side-by-side instead of end-to-end.

摘要： Systems and methods utilizing stationary and/or moveable cutting components provide limited interference with web processing operations, such as pad spin and pitch alteration. Heat, laser, fluid, or mechanical cutting operations may be used, including respectively, a heated element (e.g., wire, ribbon, bar, or embossing or perforating element) that may be triggered inductively, water or steam jets, or improved knife/anvil cooperation.
