20080276439 | Methods and apparatus for application of nested zero waste ear to traveling web - 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° into the correct orientation such that the ears and associated tape present a left ear and a right ear on the diaper. | 11-13-2008 |
20090020211 | Apparatus and method for minimizing waste and improving quality and production in web processing operations - 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. | 01-22-2009 |
20100243155 | Apparatus and method for intermittent application of stretchable web to target web - Apparatus and methods are provided to allow for cutting a stretchable first web into segments and securing the segments to a second web. The apparatus includes an infeed rate adjustment apparatus, a tension control device, a cutting apparatus, and means for securing the segments to the second web. The infeed rate adjustment apparatus is sized and configured to adjust the speed of the infeed of the first web to the cutting apparatus to space apart the segments. | 09-30-2010 |

20120159753 | APPARATUS AND METHOD FOR MINIMIZING WASTE AND IMPROVING QUALITY AND PRODUCTION IN WEB PROCESSING OPERATIONS BY AUTOMATED THREADING AND RE-THREADING OF WEB MATERIALS - 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. | 06-28-2012 |
20130005555 | METHOD OF CREATING A CROSS-MACHINE DIRECTION FOLD LINE BOUNDARY - 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. | 01-03-2013 |
20130035222 | METHODS AND APPARATUS FOR APPLICATION OF NESTED ZERO WASTE EAR TO TRAVELING WEB - 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. | 02-07-2013 |
20130037201 | METHODS AND APPARATUS FOR APPLICATION OF NESTED ZERO WASTE EAR TO TRAVELING WEB AND FORMATION OF ARTICLES USING A DUAL CUT SLIP UNIT - 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. | 02-14-2013 |
20130056576 | METHODS AND APPARATUS FOR FORMING DISPOSABLE PRODUCTS AT HIGH SPEEDS WITH SMALL MACHINE FOOTPRINT - 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. | 03-07-2013 |
20130061732 | MULTI-PROFILE DIE CUTTING ASSEMBLY - 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. | 03-14-2013 |
20130063587 | APPARATUS AND METHOD FOR MINIMIZING WASTE AND IMPROVING QUALITY AND PRODUCTION IN WEB PROCESSING OPERATIONS BY AUTOMATIC NARROW WEB TWIST DEFECT CORRECTION - 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. | 03-14-2013 |
20130075038 | DIFFERENTIAL SPEED SHAFTED MACHINES AND USES THEREFOR, INCLUDING DISCONTINUOUS AND CONTINUOUS SIDE BY SIDE BONDING - An apparatus having independently rotating shafts for producing discontinuous and continuous side by side bonding using independently rotating bonding units. | 03-28-2013 |
20130239765 | SINGLE TRANSFER INSERT PLACEMENT AND APPARATUS WITH CROSS-DIRECTION INSERT PLACEMENT CONTROL - 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. | 09-19-2013 |
