Claims
- 1. In an apparatus for cutting elongated material into predetermined lengths comprising a rotatable cutting roll having a plurality of radially extending cutting blades, and a cooperating second roll, said rolls rotating in opposite directions and between which said elongated material passes, the improvement comprising: a plurality of projections radially extending from said cutting roll, at least one of said projections being located on each side of a cutting blade and extending further radially from said cutting roll than said blades, said second roll having an elastic material at its periphery which is engaged by said projections in succession to compress the elongated material therebetween.
- 2. The apparatus of claim 1 wherein there are at least two of said projections on each side of a cutting blade.
- 3. The apparatus of claim 2 wherein said rolls have substantially similar diameters ranging from about 1 to 2 inches (2.5 to 5 cm).
- 4. Apparatus for cutting elongated material into short lengths, comprising:
- means for compressing the elongated material at discrete intervals;
- means for tensioning the elongated material between said intervals; and
- means for pressing the slightly tensioned elongated material between said intervals against a cutting edge to ultimately cut said elongated material therewith; wherein said compressing means comprises a pair of rotatable rolls between which said elongated material passes, one of said rolls having a plurality of projections radially extending therefrom at said intervals, the other of said rolls being temporarily deformable by each of said projections along its periphery to compress said elongated material, said rolls being mounted for opposed rotation and with at least two of said projections in contact with and deforming the periphery of said other roll when at rest.
- 5. The apparatus of claim 4 wherein said tensioning means and said compressing means are the same, said elongated material being tensioned when compressed at two successive intervals between said projections and said other roll.
- 6. The apparatus of claim 4 wherein said cutting edge is mounted to radially extend from said roll with one of said projections on either side thereof, said projections radially extending from said roll a greater distance, than said cutting edge.
- 7. The apparatus of claim 6 wherein said pressing means comprises said other roll as the rolls rotate.
- 8. The apparatus of claim 4 wherein said cutting edge is mounted to radially extend from said roll with at least two of said projections on either side thereof, said projections radially extending from said roll a greater distance than said cutting edge.
- 9. The apparatus of claim 8 wherein said rolls have substantially similar diameters ranging from about 1 to 2 inches (2.5 to 5 cm).
- 10. The apparatus of claim 10 wherein the number of projections on either side of each cutting edge is two.
- 11. The apparatus of claim 10 wherein said pressing means comprises said other roll as the rolls rotate.
