摘要:
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.

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.

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.

摘要:
An automatic handling device for flexible flat products, in particular catamenials, comprises: conveying means (2) on the infeed side for the serial guidance of the supplied products (1) in a main infeed direction (3), conveying means (4) on the outfeed side for the intermediate stacker units (5), the compartments (9) of which are charged with products (1), to be led off in a main outfeed direction (7) which is substantially perpendicular to the main infeed direction (3), and a feed head (8) for the products (1) between the conveying means (2, 4) on the infeed side and on the outfeed side, which oscillates about a pivoting axis (18) in the plane spanned by the main infeed direction (3) and outfeed direction (7) such that, during the oscillating motion in the main outfeed direction (7), the end (16) of the feed head (8) that is turned towards the respective intermediate stacker unit (5) is synchronous with the respective 4 compartment (9) of the intermediate stacker unit (5) for a product (1) to be transferred into this compartment (9), and that, during the oscillating motion in the opposite direction, it orients itself toward the next compartment (9).
