  • Publication number: 20240024171
    Abstract: A single step method for imparting a pattern of apertures in a fibrous nonwoven web is disclosed. The method may include providing a pinned roller bearing a pattern of aperturing pins thereon; providing an opposing roller; arranging the rollers so as to form a nip therebetween, wherein the nip has effectively zero clearance between top surfaces of the pins and outermost surfaces of the opposing roller; providing heating energy to one or both of rollers; rotating the rollers and conveying the nonwoven web through the nip, whereby material constituting fibers of the nonwoven web is at least partially melted and expressed from regions between the top surfaces of the pins and the opposing roller, and accumulates on the web about perimeter edges of the pin top surfaces. Resulting features of the nonwoven web, and products in which it may be incorporated as a component, are also disclosed.

  • Patent number: 11655572
    Abstract: Aspects of the present disclosure relate to methods and apparatuses for relofting nonwoven substrates. During the relofting process, a substrate is directed to advance in a first direction such that a length of the substrate is in a facing relationship with a radiation source. The advancing substrate is relofted by irradiating the length of the substrate with infrared radiation from the infrared radiation source. The substrate comprises a first caliper upstream of the radiation source and the substrate comprises a second caliper downstream of the radiation source greater than the first caliper. The substrate may also be redirected around an axis to advance the substrate in a second direction, wherein the second direction is different than the first direction. The axis may be selectively movable between a first position and a second position to selectively subject the substrate to infrared radiation and remove the substrate from the infrared radiation.
