Abstract: 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.

Abstract: Apparatus and methods are provided to allow for creation of a configured laminate of a non-woven material, to which a character strip is applied, the character strip exposed by either heat severing and removal of overlying materials, or intermittent application of overlying materials to leave the desired portions of the character strip exposed. A simultaneously formed core insert is applied to a preformed chassis web.
Abstract: A method for producing disposable undergarments is disclosed. The method generally comprises combining a first layer, comprising an elastic material sandwiched between layers of nonwoven material, and a second layer, comprising a backing material and a graphically printed applied patch of material layer.

Abstract: Several variations of core formation techniques and machines to produced cores are disclosed, including a large and small discrete core, formed on a screen and combined; a large and small continuous core, formed on a web; and two and three-dimensional cores, formed on a screen, and core formation on a non-woven web.
Abstract: An apparatus and method is provided for single transfer insert placement. The apparatus receives continuous web material and cuts a discrete section or pad from the web. The pad is then supported on a single transfer surface. The single transfer surface then may spin the supported pad to a desired angle and provide the pad to a receiving surface at a desired interval. The web material can be cut to different insert lengths and the placement location varied.

Abstract: A web cutting system is provided for use with a single transfer insert placement mechanism having at least one puck for transferring a discrete web and a continuous web feeding mechanism for feeding a continuous web wherein first and second rollers having substantially parallel axes and being aligned with one another form a nip at their juncture, an anvil is attached to one roller, a die is attached to the other roller, a vacuum source is coupled to one of the rollers, a plurality of vacuum apertures is formed in the same roller. One of the rollers is positioned adjacent to the single transfer insert placement mechanism and to the continuous web feeding mechanism. The continuous web is applied to one roller and at least one discrete web is transferred from the puck to the same roller after which a die cutting process of the webs occurs at the nip.
Abstract: 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.
Abstract: An elastic netting like product is carried between two or more outer layers of material, such as nonwoven or non-stretch material, which are bonded together at the open areas of the netting like structure. The resulting laminate allows for the outer layers of the laminate to be directly bonded to each other without the stretch engine material being introduced into the bond. A directionally oriented pleated laminate carrying an elastomeric layer in between two material layers is also disclosed.
Abstract: Apparatus and methods are provided to allow for creation of a configured laminate of a non-woven material, to which a character strip is applied, the character strip exposed by either heat severing and removal of overlying materials, or intermittent application of overlying materials to leave the desired portions of the character strip exposed. A simultaneously formed core insert is applied to a preformed chassis web.
Abstract: Apparatus and methods are provided to allow for short length adhesive application in the machine direction. These short length adhesive applications can be used in creation of pocket style rear waistband feces containment features onto running webs for use in diaper manufacturing. Different configurations of adhesive and patch applications can be employed to create the pockets.
Abstract: A method of reversing direction of an article, or of speeding up or slowing down an article is disclosed by engaging an article with a first belt to move the article in a first direction; disengaging the article from the first belt; and then engaging the article with a second belt to move the article at a different speed. An apparatus to change speed of an article is also disclosed by a first belt rotating in a first direction; a second belt rotating in the direction at a second speed; the first belt engaging an article at a first time while the second belt is disengaged with the article, the first belt disengaging the article at a second time, and the second belt engaging the article at a third time while the first belt is disengaged with the article.
Abstract: Apparatus and methods are provided to minimize waste and improve quality and production in web processing operations. The apparatus and methods provide defect detection both before and after application of component patches to a traveling web to create a product. Web defect detection may be provided by way of at least one visual inspection station located upstream from the patch applicator. Patch defect detection may be accomplished by way of a visual inspection station located proximate the patch applicator. If defects are detected in either the traveling web or the component patch prior to patch application, patch application may be prevented until both a satisfactory web and patch are provided. If defects are detected after patch application, the resulting product may be culled. Furthermore, the apparatus may be provided with diagnostic software to warn against extant or imminent machine complications.

Abstract: A die roll is disclosing have multiple alternating patterns. Cutting edges and non-cutting edges on the die roll are phased with cutting surfaces and relieved areas on the anvil, respectively. Multiple cut profiles are achieved from a single die/anvil combination.
Abstract: Apparatus and methods are provided to minimize waste and improve quality and production in web processing operations. The apparatus and methods provide defect detection in deposition of acquisition material, which on current machines frequently flips and is difficult to detect when it has flipped causing manufacturers to scrap thousands of products. Using the present invention, defects are able to be detected by discerning a difference in the appearance from side to side with a vision camera, and an acquisition inverter can flip the material to a correct orientation.

Abstract: The present invention provides machinery used to create products (for instance disposable products). The machinery is operated at high speed, with the machine occupying a small footprint. Materials can be fed into the manufacturing process vertically (from above or below), using assembly stations to feed completed components into the system at appropriate stations. Additionally, restocking of raw components can be accomplished by robotic means of transferring the raw material from staging areas into infeeding or splicing stations, without the need for human operators.

Abstract: 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. A cut/slip operation is performed on an incoming web carried by a transfer drum, and the cut/slip pieces are further divided and next separated by a second transfer drum and bonded to incoming webs.

Abstract: Apparatus and methods are provided to allow for creation of a cross-machine direction fold boundary, so that a laminate with a defined foldover can be created. A laid open two-ply material can then undergo processing operations such as addition of discrete disposable product components, or printing, and then be laid closed and sealed to form disposable products.
Abstract: A variable infeed speed device is provided in order to apply under proper tension ribbon type devices in a sinusoidal manner to a running web.
