Abstract: A method of spraying patterns on a web that includes directing at least one intermittent spray of liquid onto the web to form a pattern on the web; sensing a position of a leading edge of at least one of the spray and the pattern relative to one or more references on the web; generating a first correction signal when the leading edge is out of position; and adjusting the spray of liquid in response to the first correction signal to correctly position a leading edge of a subsequent pattern. The method further includes sensing a position of a trailing edge of at least one of the spray and the pattern relative to one or more references on the web; generating a second correction signal when the trailing edge is out of position; and adjusting the spray of liquid in response to the second correction signal to correctly position a trailing edge of subsequent patterns.

Abstract: A composite elastic material including a nonwoven layer, a layer of substantially parallel elastomeric filaments and a bonding component that joins the elastic filaments to the nonwoven layer. The nonwoven layer has a plurality of bonding elements resulting in greater total bonding in a first direction than in total bonding in a second direction; the second direction being nonparallel to the first direction. The configuration of the bonding elements of the nonwoven layer is used to control properties of the composite elastic material. Additional laminate bond elements on the composite elastic material, having greater bond area oriented appropriately can further control properties of the composite elastic.

Abstract: Disclosed is a process for the detection of marked components of a composite article. The present invention relates to detecting the presence, position, concentration and/or distribution of one or more components in a composite article, and to registration inspection of a composite article using infrared radiation. In one embodiment of the invention, infrared blockers, such as absorbing infrared blockers, are incorporated into the component of interest in the composite to increase the visibility of the marked component during inspection.
