Embodiment Construction

[0064]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, which is defined by the claims.

[0065]It is noted that the present waste minimization techniques and apparatus are described herein with respect to products such as diapers, but as previously mentioned, can be applied to a wide variety of processes in which discrete components are applied sequentially.

[0066]Referring to FIGS. 1A and 1B, a two-level disposable product manufacturing process is disclosed. Portions of the disposable product are formed on a floor level, and other portions are formed on an upper or mezzanine level.

[0067]On the floor level, the web processing operation starts with incorporating raw materials such as pa...

Abstract

A machine for producing disposable products anticipates when a current run of a product size is coming to an end, and therefore begins loading of material rolls intended for the next product size or code that will be run. An integrated production facility layout automatically orders and stocks raw material based on production plans, and commands a production machine to produce specific products of differing configurations, and automatically loads appropriately sized raw materials into the process.

Description

RELATED APPLICATIONS[0001]This application claims the benefit of co-pending U.S. Provisional Patent Application Ser. No. 62 / 240,622, filed 13 Oct. 2015.BACKGROUND OF THE INVENTION[0002]The invention disclosed herein relates to an apparatus and methods for forming disposable products such as diapers at very high speeds, while automatically scheduling certain aspects of production, including material loading, splicing, reloading. While the description provided relates to diaper manufacturing, the apparatus and method are easily adaptable to other applications.[0003]In particular, the present invention relates to material unwind systems. Turret unwind systems, which automatically splice an expiring roll of material with a waiting roll of material are disclosed, the turret unwind systems provided with a recovery system for recovering end portions of the material carried by the expiring roll, and automatically separating an expiring roll core from the expiring material. Two waste streams...
