  • Patent number: 11426992
    Abstract: 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.

  • Patent number: 11325801
    Abstract: A machine for producing disposable products anticipates when a current run of a product size is coming to an end, and therefore begins loading of material rolls intended for the next product size or code that will be run. An integrated production facility layout automatically orders and stocks raw material based on production plans, and commands a production machine to produce specific products of differing configurations, and automatically loads appropriately sized raw materials into the process.

  • Patent number: 11034539
    Abstract: Apparatus and methods are provided to minimize waste and improve quality and production in web processing operations. The apparatus and methods provide defect detection in deposition of acquisition material, which on current machines frequently flips and is difficult to detect when it has flipped causing manufacturers to scrap thousands of products. Using the present invention, defects are able to be detected by discerning a difference in the appearance from side to side with a vision camera, and an acquisition inverter can flip the material to a correct orientation.

  • Patent number: 10792194
    Abstract: Apparatus and methods are provided to allow for creation an elastic laminate. Non-stretched elastic can be laid at peaks over a nonwoven layer contained in valleys and atop peaks. Stretched elastic can be laid over tented nonwoven to create nonwoven tunnels when a second nonwoven is laid atop the first nonwoven and elastic, and the tunnels resist un-stretching of stretched elastic strands by frictional or obstruction forces. A laminated material comprising a first and second layer of material bonded at spaced apart bond sites is disclosed, with a plurality of elastic strands disposed in a non-linear manner between said first and second layer of material, so that said strands meander in a cross-machine direction and traverse a machine direction line, restraining movement of the strands by frictional forces between the strands and the non-woven layers.

  • Patent number: RE48182
    Abstract: Apparatus and methods are provided to minimize waste and improve quality and production in web processing operations. The apparatus and methods provide defect detection both before and after application of component patches to a traveling web to create a product. Web defect detection may be provided by way of at least one visual inspection station located upstream from the patch applicator. Patch defect detection may be accomplished by way of a visual inspection station located proximate the patch applicator. If defects are detected in either the traveling web or the component patch prior to patch application, patch application may be prevented until both a satisfactory web and patch are provided. If defects are detected after patch application, the resulting product may be culled. Furthermore, the apparatus may be provided with diagnostic software to warn against extant or imminent machine complications.
