Device and method for treating (softening) continuously conveyed material

A device for treating a continuously conveyed thread group in order to produce tire cord has a roller pair for locally softening the thread group, wherein each roller (3, 4) is provided with a toothing formation. When the thread group is guided through between the rollers (3, 4), it is deformed by the mechanical loading of the teeth. The rollers (3, 4) can be driven in a separate manner directly or indirectly by way of actuable electric motors, as a result of which the gap spacings (A) and (B) can be set precisely identically. The axle spacing (C) of the two rollers (3, 4) can be set depending on the fabric thickness and the fabric type.

The present invention is directed to a method of incrementally stretching polymeric film formed from a blown film extrusion process. The present invention is further directed to a polymeric bag formed from an incrementally stretched polymeric film. The incremental stretching is performed on a collapsed polymeric bubble via a pair of intermeshing rollers. The incrementally stretched polymeric film may be stretched only along a portion of its width. The polymeric bag may be a drawstring trash bag with an extended hem where only the extended hem of the polymeric bag comprises incrementally stretched polymeric film.

20170037209 · 2017-02-09 ·

A process for providing indicia and an elastic-like behavior to a web substrate is disclosed. The process comprises the steps of: providing a web substrate; printing indicia on the web substrate; and, providing the web substrate with a plurality of first regions and a plurality of second regions comprising the same material composition. A portion of the first regions extend in a first direction while the remainder of the first regions extend in a second direction perpendicular to the first direction to intersect one another. The first regions form a boundary completely surrounding the second regions. The second regions comprise a plurality of raised rib-like elements. The first regions undergo a molecular level and geometric deformation and the second regions initially undergo a substantially geometric deformation when the web material is subjected to an applied elongation along at least one axis.

Manufacture of composite optical materials

A polymer opal material comprises a three dimensionally periodic arrangement of core particles in a matrix material and exhibits structural color via Bragg reflection. IN a process for manufacturing such a material, a sandwich structure is provided, of a precursor composite material held between first and second sandwiching layers. A relative shear strain of at least 10% is imposed on the precursor composite material by curling the sandwich structure around a roller. The shear strain is cycled, in order to promote the formation of the three dimensional periodic arrangement.
