Continuous edge folds of a top sheet in disposable products prepare the top sheet for placement/attachment of discrete side panels to the folded-over portion of top-sheets oriented so that the side panels lay on top of the top-sheet without any further folding steps required. Later, a back sheet can be added and back sheet edges then folded over to cover edges of top-sheet/side panel sandwich.

Method of forming bonds between discrete components of disposable articles

The present invention provides a method of providing a disposable product with zero waste ear formation and attaching the ears to a running chassis web.

Methods and apparatus for application of nested zero waste ear to traveling web

A series of elastic break brakes are provided throughout a travel path of elastics in a machine operation. Elastic strands thread through each individual brake mechanism, and if an elastic strand breaks downstream, a natural snap back of the elastic, which ordinarily travels through the system under tension, drives an immediately upstream cam mechanism back, and holds the elastic thread in place at the elastic break brake immediately upstream of the break as to minimize rethreading required downstream of the elastic break brake.

Apparatus and method for applying parallel flared elastics to disposable products and disposable products containing parallel flared elastics

Elastic break brake apparatus and method for minimizing broken elastic rethreading

The present invention provides a method of providing a disposable product with a contoured leg opening. In this method at least one chip is removed from at least one ear of a disposable product. The chip may be removed from an ear prior to attaching the ear to the chassis web. Alternatively, the chip may be removed from the ear after the ear is attached to the chassis web.

Apparatus and methods are provided to minimize waste and improve quality and production in web processing operations. A first non-elastomeric layer is bonded with an elastomeric layer, and to a second non-elastomeric layer. The apparatus and methods provide defect detection in the elastomeric layer and triggers an unthreading/rethreading sequence. Web defect detection may be provided by way of at least one visual inspection station. If defects are detected in the elastic layer, the resulting products may be culled.

Apparatus and method for minimizing waste and improving quality and production in web processing operations by automated threading and re-threading of web materials

The present invention provides a process wherein a rotary knife or die, with one or more cutting edges, turns against and in coordination with a corresponding cylinder to create preferably trapezoidal ears. Ear material is slit into two lanes, one for a left side of a diaper and the other for a right side of a diaper. Fastening tapes are applied to both the right and the left ear webs. The ear material is then die cut with a nested pattern on a synchronized vacuum anvil. The resulting discrete ear pieces however, due to the trapezoidal pattern of the ears, alternate between a correct orientation and an incorrect (reversed) orientation. The reversed ear is required to be rotated 180&#xb0; into the correct orientation such that the ears and associated tape present a left ear and a right ear on the diaper.

A method and apparatus for applying tape tabs to a traveling web of material, for example, placement of tape tabs on a running web of disposable undergarments. A pair of wheels each has a protuberance come in contact with the running web of material, which comes in contact with an infeeding tape web. The invention allows placement of tape tabs at asymmetrical spacings, where placement of the tape from contact of the first wheel and protuberance may not be equally or centrally spaced from placement of the tape by the second wheel and protuberance.
