AI Technical Summary

Benefits of technology

The patent describes a way to make a non-woven material textured and easier to grip, by using intermeshing gears. The material can also be heated to make it easier to touch with smooth or rough surfaces. This makes it easier to switch the surface being controlled.

Problems solved by technology

This process holds and transfers sufficiently, but has high cost to acquire this vacuum and high cost for noise abatement.

Embodiment Construction

[0048]Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structures. While the preferred embodiment has been described, the details may be changed without departing from the invention.

[0049]FIGS. 1-6 generally describe a rotating anvil using vacuum to hold discrete pieces on a moving web, in the prior art. High speed vacuum is also used in a similar manner to transport discrete pieces and entire webs on flat conveyors through the manufacturing process. The present invention relates to transporting discrete pieces and entire webs through both rotation and flat conveyance by minimizing the vacuum usage shown in FIGS. 1-6 and on prior art flat vacuum conveyors (not shown).

[0050]Referring to the drawings there is seen in FIG. 1 a diagrammatic illustration of a prior art process for applying tabs to webs in a diap...

Abstract

Provided are methods and apparatus for transporting either an entire web or discrete components of disposable products. The invention is a means of conveying the web or diaper components down the machine using mechanical forces to grip the nonwoven web and transfer it from one belt or roll to another without or reducing added vacuum. There is a carrier nonwoven web that goes down the length of the machine and other substrates are added on top of this. Methods and apparatus are disclosed to provide sufficient gripping to allow transport of diaper components through the fabrication process. Securing and releasing forces are supplied so that the components can be retained at some points and released at others.

Description

RELATED APPLICATIONS[0001]This application claims the benefit of co-pending provisional application Ser. No. 62 / 010,773 filed 11 Jun. 2014, the entirety of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]This invention relates to a method and apparatus for rapidly and accurately transporting a discrete article or a web of material. This invention is not limited to its preferred use, carrying components of a disposable diaper or sheet of paper; but instead the methods and apparatus' of the present invention may be used in wide ranging applications.[0003]Generally, diapers comprise an absorbent insert or patch and a chassis, which, when the diaper is worn, supports the insert proximate a wearer's body. Additionally, diapers may include other various patches, such as tape tab patches, reusable fasteners and the like. The raw materials used in forming a representative insert are typically cellulose pulp, tissue paper, poly, nonwoven web, acquisition, and elast...
