A process for producing a nonwoven web material with improved edge quality, and the product thereof, are disclosed. The process may include the steps of forming a batt of polymeric fibers; consolidating the batt in a z-direction and thereby forming a nonwoven web material, conveying the nonwoven web material to a nip between a bonding roller and anvil roller, and impressing a pattern of bond impressions into the nonwoven web material, the bond impressions lying along a cut path. When the web is subsequently cut along the cut path, fibers proximate the cut path are immobilized by the bonds, providing for relatively neater, cleaner cut edges and reducing the number of loose fibers that may be released into the plant environment in downstream processing operations.

The present disclosure relates to methods and apparatuses for manufacturing absorbent articles. More particularly, the systems and methods for folding absorbent articles advancing in a converting line may be configured with tucker blades that prevent opposing end regions of absorbent articles from colliding directly with each other as the absorbent articles are being folded.

Methods and apparatuses for folding absorbent articles

A method for removing dust-carrying air from a moving paper web is disclosed. The method includes the steps of: providing a moving web, the web having a first side and a second side, the web moving at a sufficient rate to produce a boundary layer of adjacent dust-carrying air; providing a NACA duct, the NACA duct having an intake opening and walls that diverge in increasing cross-sectional area to an exhaust opening having greater cross sectional area than the intake opening; and submerging the intake opening into the boundary layer to scavenge dust-carrying air from the boundary layer.

Method and apparatus for particulate removal from moving paper webs

An apparatus for removing particulate-carrying air from a moving web. The moving web has a first side and a second side. The apparatus includes a NACA duct positioned in a non-contacting relationship on a first side of the moving web, and at least partially submerged in a particulate-carrying boundary layer of the moving web. The NACA duct can have an intake opening and an exhaust opening such that when the intake opening is submerged in the boundary layer at least a portion of the particulate-carrying air from the boundary layer enters the intake opening and exits the exhaust opening, thereby scavenging particulate-carrying air from said boundary layer.

The present disclosure relates to a method for redirecting cut web products and/or rejecting cut web products. The method comprises advancing a plurality of cut web products along a first path and providing a redirecting or folding device for folding the plurality of cut web products and/or delivering the folded cut web products to a second path. Prior to reaching the folding device, the cut web products may be determined to be defective. The folding device can be accelerated, decelerated, or substantially stopped, such that a selected cut web product is not delivered to the second path, thereby rejecting the selected cut web product. The present disclosure additionally comprises an apparatus for redirecting and/or rejecting cut web products.

Method and apparatus for selective folding or redirecting

An automatic handling device for flexible flat products, in particular catamenials, comprises: conveying means ( ) on the infeed side for the serial guidance of the supplied products ( ) in a main infeed direction ( ), conveying means ( ) on the outfeed side for the intermediate stacker units ( ), the compartments ( ) of which are charged with products ( ), to be led off in a main outfeed direction ( ) which is substantially perpendicular to the main infeed direction ( ), and a feed head ( ) for the products ( ) between the conveying means ( ) on the infeed side and on the outfeed side, which oscillates about a pivoting axis ( ) in the plane spanned by the main infeed direction ( ) and outfeed direction ( ) such that, during the oscillating motion in the main outfeed direction ( ), the end ( ) of the feed head ( ) that is turned towards the respective intermediate stacker unit ( ) is synchronous with the respective compartment ( ) of the intermediate stacker unit ( ) for a product ( ) to be transferred into this compartment ( ), and that, during the oscillating motion in the opposite direction, it orients itself toward the next compartment ( ).
