摘要:
A process and apparatus for handling flexible components during manufacturing an assembled article. The process and apparatus involve at least one transfer the flexible components from one support surface to another. Control of the position and orientation of the flexible components during transfer from one support surface to another is managed through the spacing between the support surfaces and may further be managed by coordinated air pressure changes.

The present disclosure relates to methods and apparatuses for manufacturing absorbent articles, and more particularly, apparatuses and methods utilizing multiple processing stations for processing absorbent articles and being configurable to move along various predetermined travel paths defined by radii that may be constant or variable. Particular embodiments of apparatuses and methods of manufacture include a processing wheel having a plurality of processing stations which orbit around a rotation axis. The processing stations may be configured to perform various types of operations associated with the manufacture of absorbent articles while the processing stations orbit around the rotation axis. The processing wheel can be configured to adjust the path along which the processing stations orbit as the processing wheel rotates around the rotation axis. As such, the orbit path can be adjusted to accommodate the manufacture of different sized blanks without the need to physically move or relocate and realign other process apparatuses, such as for example, sealing stations.

A web centering and spreading processing system and related method are used to center a moving web (20) and then spread the web in order to remove wrinkles from the web. The centering mechanism (74), in one example, has a centering roller (69) that receives the wrinkles web. The outer edges of the web, which tend to be uneven arid not centered, are detected and a signal is sent to the centering roller to move the web laterally and thereby center the web. The centered web, which is substantially centered but not necessarily precisely centered, moves to a spreader station (70) that receives the web and spreads it thereby removing any wrinkles in the web. The spreader station may include a roller with a recessed center area and that has at least one set of contoured plates that move across the roller from an inner position to an outer position. The plates have gripping surfaces that grip the edges of the web and spread the web to remove the wrinkles. The plates also have an inner smooth area that, in conjunction with the recessed area, allow the inner area of the web to essentially float and thereby be spread to remove the wrinkles without binding.

A mechanical activation system has a first activation member, a second activation member, an activation zone, and a non-slip zone. The first activation member has a first plurality of teeth, and the second activation member has a second plurality of teeth. The first plurality of teeth is capable of intermeshing with the second plurality of teeth. The activation zone includes a first portion of the first plurality of teeth and a first portion of the second plurality of teeth. The first portion of the first plurality of teeth and the first portion of the second plurality of teeth include teeth having continuous tips. The first non-slip zone includes a second portion of the first plurality of teeth or a second portion of the second plurality of teeth. The second portion includes a tooth having a discontinuous tip.

A disposable absorbent article has a chassis, a first side panel, a second side panel, and a reinforcement element. The chassis includes a topsheet, a backsheet attached to at least a portion of the topsheet, and an absorbent core disposed between the topsheet and the backsheet. The first side panel has an inner end and an outer end and extends outward from a first longitudinal edge in a first waist region. The second side panel extends outward from the first longitudinal edge in a second waist region. The first side panel is configured to join to the second side panel adjacent to the outer end of the first side panel. The reinforcement element is joined to the outer end and limited to the outer end of the first side panel.

An apparatus for reducing downtime in processes utilizing continuous webs as a raw material upon the detection of a defective portion in a continuous web includes a defect detection member. The defect detection member (140) detects the defects in the continuous web (112) while a first engaging member (150) can stop or slow the speed of the continuous web upon the detection of the defective portion. A second engaging member (160) can receive the defective portion and separate the defective portion from the continuous web and can attach non-defective portions together. A storage element (124) can provide a contingent amount of the continuous web to any downstream processes while the continuous web is stopped or slowed by the first engaging member.
摘要:
A disposable diaper comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet. The topsheet and backsheet define a periphery and longitudinal edges, portions of the longitudinal edges define leg openings when the diaper is worn. The diaper has a discrete edge band joined to the longitudinal edges at least at the portions defining leg openings when the diaper is worn. An apparatus for affixing a discrete edge band onto a portion of a longitudinal edge of a continuous web and methods for affixing discrete edge band onto a predetermined portion of a longitudinal edge of a continuous web are also provided.

An apparatus and method for producing an elastomeric nonwoven laminate including a plurality of elastic strands joined to a nonwoven web in a controlled distribution is provided. The apparatus includes an extruder for extruding a plurality of elastic strands onto a cooled surface of a rotating drum, which transports the strands in parallel alignment to a nip formed between two rollers rotating about parallel axis. The drum transfers the plurality of strands to the nip in a controlled distribution where it is bonded with the nonwoven.

An elastomeric nonwoven laminate and a process for producing the elastomeric nonwoven laminate are proved. The elastomeric nonwoven laminate includes a first nonwoven, a second nonwoven and a plurality of elastic strands. The plurality of elastic strands is attached to the first nonwoven while under a strain producing a corrugated intermediate laminate once the strain is relieved. A second nonwoven is joined to the corrugated intermediate laminate and subsequently mechanically activated forming an elastomeric nonwoven laminate.
摘要:
Aspects of the methods herein relate to the fabrication of diaper pants wherein side panels connected with the first waist region of a discrete chassis are conveyed in a first direction until a second waist region advances past a nip. The crotch region of the chassis is then redirected into the nip, folding the chassis to position the second waist region into a facing relationship with the first waist region. The folded chassis is then conveyed in a second direction with the side panels positioned on panel conveyors extending laterally outward from the first waist region. As the folded chassis travels in the second direction, the panel conveyors twist to position end regions of the side panels to connect with the second waist region of the folded chassis. The side panels and the waist regions of the folded chassis may also be compressed between the panel conveyors and a roller.
