Problems solved by technology
This approach has been satisfactory when such portions to be turned or folded are not unduly large and / or pliable; but is not entirely satisfactory in all circumstances, such as where the portion to be so manipulated is both highly pliable and relatively large (i.e., floppy).
For such members, friction with air (at the machine direction speed) or the stationary surface of the structure may cause undesired and / or unpredictable results such as uncontrolled turning or flipping, or unacceptably imprecise positioning of the member following the operation.

[0035]Definitions
[0036]“Downstream”—with respect to components of a manufacturing line, relates to the general direction of forward travel of materials through the manufacturing line toward completion of a product.
[0037]“Inner”—with respect to a pant or feature thereof as described herein, generally refers to the inside, or wearer-facing side, of the pant or feature.
[0038]“Lateral” and forms thereof—with respect to a pant or feature thereof as described herein, refers to a direction substantially parallel to its waist edges. With respect to a machine direction, refers to a direction substantially perpendicular to the machine direction.
[0039]“Length”—with respect to a pant or feature thereof as described herein, unless otherwise specified, refers to a dimension measured along a line substantially perpendicular to the waist edges of the pant.

Abstract
An apparatus for turning a pliable member extending from an article moving along a machine direction is disclosed. The apparatus may include a conveyor system adapted to convey the article along the machine direction, and a member turning system situated alongside the conveyor system in a position to contact the pliable member. The member turning system may include first and second pulleys at first and second locations alongside the conveyor system and having axes of rotation transverse to the machine direction, and a flexible belt engaged about the first and second pulleys in a twisted configuration. The flexible belt may define an operative twisting moving surface between the first and second pulleys that engages the pliable member and turns it as the article moves along the machine direction.
Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 425,019, filed Dec. 20, 2010, the substance of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The business of manufacturing wearable absorbent articles such as disposable diapers and absorbent pants may involve rates of production exceeding 450 articles per minute, in order to sustain a competitive operation. For a typical diaper size this may translate to a speed, at which materials and articles being manufactured move through a line in a machine direction, exceeding 200 meters per minute. Commercial quantities of such articles are made on complex manufacturing lines having modules or components designed to perform the varying tasks required to convert input materials (such as nonwoven webs, polymeric films, loose cellulosic fiber materials, particulate absorbent gelling materials, adhesives, elastomeric strand materials, etc.) to the f...
