Claims
- 1. An apparatus for forming a collar cut in a fiber can from a sheet of body stock material and a sheet of label stock material comprising a supporting framework, means for winding the body stock material and label stock material into tube form with the label on the outside of the body stock material at least one knife mounted upon the framework and adapted to be positioned to engage can label stock material just before the label stock material is wound into tube form, and drive means for the knife to move the knife rectilinearly with respect to the tube and parallel to the axis of the tube being formed at the same velocity as the velocity component of the label material in the direction of knife movement.
- 2. The apparatus of claim 1 wherein the knife is mounted upon a roller chain entrained over chain sprockets and the knife when located along one run the chain sprockets is engaged with the label material and the other run of the chain between the sprockets returns the knife to its starting position.
- 3. The apparatus of claim 2 wherein said means is a tube winder operatively connected to the tube for winding the tube and said sprocket is operatively connected to the tube winder for movement in synchronization therewith.
- 4. The apparatus of claim 3 wherein a phase shifting means is operatively connected between the tube winder and the sprocket for advancing or retarding the sprocket and knife with respect to the tube winder whereby the knife can be made to cut in a predetermined position with respect to the label material.
- 5. The apparatus of claim 4 wherein a sensor is connected to the phase shifting means and operatively associated with the label stock material to advance or retard the phase shifting means responsive to the passage of registration marks on the label stock material.
- 6. The apparatus of claim 1 wherein the apparatus includes a drive shaft journaled for rotation parallel to the tube, a pair of parallel horizontally spaced apart sprocket shafts mounted at substantially right angles to said drive shaft, means coupling at least one of the sprocket shafts to rotate with the drive shaft, a sprocket mounted on each of the sprocket shafts, a knife support chain entrained between the sprockets and at least one knife mounted upon the chain.
- 7. The apparatus of claim 6 wherein a pressing wheel is connected to the apparatus and positioned in engagement with the adjacent edges of the label stock material at the point where the label stock material is wound onto the tube.
- 8. The apparatus of the claim 7 wherein the label has adjacent edges and the pressing wheel is castered to follow the adjacent label edges.
- 9. The apparatus of claim 6 wherein the sprocket shafts are pivotable about the center of the drive shaft.
- 10. The apparatus of claim 6 wherein the chain is provided with a plurality of cutting knives and the distance between each cutting knife is equal to the length of the cans being formed.
