Abstract
A method for producing one or more individual stacks of superimposed, secured together, expandable tubular strips forming an expandable honeycomb panel. The strips coated with adhesive are advanced sequentially to the inlet of a stacking chamber having an elevated floor with a longitudinally extending slot of a length to receive each strip and which is narrower than the width of the strips to be delivered thereto. The strip so delivered is pushed up through the narrower slot and against the strip just previously delivered to the chamber, to adhere it to the latter strip. The chamber has a weight bar to exert a downward force on the stack of strips to provide good adherence between the strip.
Claims4
A method of producing one or more individual stacks of superimposed, expandable tubular strips forming an expandable honeycomb panel, said method comprising the steps of:
- providing a continuous strip of material containing at least one line of adhesive, feeding the continuous strip of material through a cutter for cutting the continuous strip into individual strips of flexible material each forming a flat, expandable tubular body and having at least a central region on one side thereof which is adapted to be adhered to an adjacent strip when it is in contact therewith;
- accelerating said strips sequentially to the inlet of a stacking chamber having a floor with longitudinally extending slot of a length to receive each strip and which is narrower than the width of the strips to be delivered thereto, then sequentially pushing each strip through the narrower slot when in alignment with said slot and the strip or strips already in said chamber and adhering the adjacent strips together in the chamber wherein said stacking chamber is an elevated stacking chamber above said inlet thereto and said slot is in the bottom of said stacking chamber so each strip of the stack is pushed upwardly through said slot and against the strip above it.
A method of producing one or more individual stacks of superimposed, expandable tubular strips forming an expandable honeycomb panel, said method comprising the steps of:
- providing a continuous strip of material;
- feeding the continuous strip of material through a cutter for cutting the continuous strip into individual strips of flexible material each forming a flat, expandable tubular body and having at least a central region on one side thereof which is adapted to be adhered to an adjacent strip when it is in contact therewith;
- providing at least one band of adhesive to the top of the central portion of at least some of the strips, accelerating said strips sequentially to the inlet of a stacking chamber having a floor with longitudinally extending slot of a length to receive each strip and which is narrower than the width of the strips to be delivered thereto;
- then sequentially pushing each strip through the narrower slot when in alignment with said slot and the strip or strips already in the chamber and adhering the adjacent strips together in the chamber, wherein said stacking chamber is an elevated stacking chamber above said inlet thereto and said slot is in the bottom of said stacking chamber so each strip of the stack is pushed upwardly through said slot and against the strip above it, wherein each such strip when pushed through the slot in the bottom of the stacking chamber is forced against the strip above it to raise the same and provide better adhesion between the strips.
