Abstract
A method and apparatus characterized by slitting a sheet of material having a natural resilience into a plurality of strips to form a body of such strips and folding each of the strips into a zig-zag shape. The folding step/function is accomplished by advancing the plurality of strips against a restriction acting on the body of strips in such a manner that the natural resilience of the material produces substantially uniform adjacent opposite folds thereby causing each of the strips to assume a zig-zag shape.
Claims57
A method of producing a product from a sheet of material having a natural resilience, said method comprising the steps of:
- slitting the sheet of material into a plurality of strips to form a body of such strips, said slitting being performed by a slitting device;
- and
- sequentially folding each of the strips into a zig-zag shape, wherein said sequentially folding step is accomplished by advancing the plurality of strips against a restriction acting on the body of strips in such a manner that the natural resilience of the material produces substantially uniform adjacent opposite folds thereby causing each of the strips to assume substantially the same zig-zag shape.
An apparatus for producing a resilient product from a sheet of material having a natural resilience, said apparatus comprising:
- means for slitting the sheet of material into a plurality of strips, whereby to form a body of such strips, said means for slitting including a slitting device, and,
- means for advancing the plurality of strips against a restriction acting on the body of strips in such a manner that the natural resilience of the material produces substantially uniform adjacent opposite folds thereby causing each of the strips to assume substantially the same zig-zag shape.
A method of producing a paper product from a sheet of paper, said method comprising the steps of:
- cutting the sheet of paper into a plurality of strips, whereby to form a body of such strips, said cutting being performed by a cutting device;
- and
- sequentially folding each of the strips into a zig-zag shape, characterized in that said sequentially folding step is accomplished by advancing the plurality of strips against a restriction acting on the body of strips in such a manner that the natural resilience of the paper produces substantially uniform adjacent opposite folds thereby causing each of the strips to assume substantially the same zig-zag shape.
An apparatus for producing a paper product from a sheet of paper, said apparatus comprising:
- means for cutting the sheet of paper into a plurality of strips, whereby to form a body of such strips, said means for cutting including a cutting device,
- characterized by the inclusion of means for advancing the plurality of strips against a restriction acting on the body of strips in such a manner that the natural resilience of the paper produces substantially uniform adjacent opposite folds thereby causing each of the strips to assume substantially the same zig-zag shape.
A method for producing a product from a sheet of paper, said method comprising the steps of simultaneously slitting the sheet of paper into a plurality of strips to form a body of strips and sequentially folding each of the strips into a zig-zag shape;
- wherein said sequentially folding step is accomplished by advancing the body of strips against a restriction acting on the body of strips;
- wherein said advancing step includes advancing the strips through a common discharge chute and towards an exit opening in the discharge chute.
An apparatus for producing a product from a sheet of paper, said apparatus comprising means for simultaneously slitting the sheet of paper into a plurality of strips to form a body of strips and means for sequentially folding the plurality of strips;
- wherein said sequentially folding means includes means for advancing the plurality of strips against a restriction acting on the body of strips;
- and
- wherein said means for advancing includes a common discharge chute having an exit opening towards which the strips are advanced.
A method of producing a product from a sheet of material having a natural resilience, said method comprising the steps of:
- slitting the sheet of material into a plurality of strips to form a body of such strips, and
- sequentially folding each of the strips into a zig-zag shape wherein said sequentially folding step is accomplished by advancing the plurality of strips against a restriction acting on the body of strips in such a manner that the natural resilience of the material produces adjacent opposite folds thereby causing each of the strips to assume a zig-zag shape.
