Abstract: A machine and method for the continuous folding of sheet material into different three-dimensional patterns. The innovative machine and method folds sheet material by force converging the sheet to a final stage that imparts a final fold or pattern into the sheet material, the patterns selectively including one of a Chevron pattern, a honeycomb-like pattern, a double-sided inclined folded core structure, and singular inclined direction folded core structure sheet material.

Abstract: The coupler with expanding fittings can be configured with an inner sleeve having an annular wall with an outwardly extending lip about an end of the sleeve. The wall of the inner sleeve can have a passage defined therein extending from adjacent the valve body and having a discharge opening adjacent the lip, or can have external threading on the outwardly extending lip. The coupler has an outer sleeve with an attached pipe flange at a first end and an inwardly extending lip at an opposing second end. The inner sleeve lip is slidably or threadingly disposed within the outer sleeve, the outer sleeve lip encircling the inner sleeve. The outer sleeve travels along the outward surface of the lip of the inner sleeve, the range of travel of the order sleeve being limited by the inwardly extending lip on the outer sleeve.

Abstract: A machine and method for the continuous folding of sheet material into difference three-dimensional patterns is featured. The innovative machine and method folds sheet material by force converging the sheet to a final stage that imparts a final fold or pattern. Unique programming allows for the change of convergence sequencing and change of materials.
