Abstract
The method and apparatus for fabricating honeycomb expandable insulation panels disclosed herein includes a method and apparatus for folding a continuous thin film of flexible plastic material into a uniform, open faced tubular configuration and for heat setting the folds in permanent sharp creases. It also includes a rotatable rack apparatus for continuously stacking successive lengths of the tubular formed plastic film one on top of another on flat surfaces and adhering them together in the form of a neat, uniform expandable panel of interior honeycomb cell configuration.
Claims6
An expandable and contractable honeycomb panel comprised of:
- a plurality of elongated open faced tubular plastic film sections laminated together one on top of another, each tubular section having a continuous bottom portion, a front top portion folded partially over the front side of the bottom portion, a rear top portion folded partially over the rear side of the bottom portion, in such a manner that the respective inside edges of the front and rear top portions approach nearly but do not overlap each other, and sharp, permanently set creased folds between the respective top portions and the outside edges of the bottom portion in a manner tending to bias the top portions toward the bottom portion, the outside surface of the top portions adjacent the inside edges thereof being adhered to the outside surface of the bottom portion of the next adjacent tubular film.
An expandable and contractable honeycomb panel comprised of:
- a plurality of elongated tubular sections laminated together one on top of another, each tubular section having a bottom portion, a front top portion folded over the front side of the bottom portion, a rear top portion folded over the rear side of the bottom portion and sharp folds separating the respective top portions and the bottom portion, the outside surface of the top portions at locations spaced from said folds being adhered to the outside surface of the bottom portion of the next adjacent tubular section.
