Abstract
A tabbed honeycomb structure or pleated panel is made from a stack of collapsed multi-cellular material. The stack is split at bond lines thereby forming the panels of pleated or honeycomb material having a joint tab on one face.
Claims13
A method for producing a pleated and tabbed fabric comprising the steps of:
- pleating a sheet of material to form a stack of pleated material having fabric layers and pairs of opposed pleat faces;
- applying at least one bond line between each pair of opposed pleat faces so that the applied bond lines are in one of two bond line planes which are normal to the pleat faces;
- stacking the opposed pleat faces on top of one another to bond the pleat faces together thereby forming a stack of cellular material having at least two sets of bond lines each set aligned in a bond plane transverse to the pleat lines;
- and
- removing and discarding a portion of each fabric layer adjacent a bond plane to form at least one panel of pleated and tabbed fabric.
