Apparatus for cutting moving material transversely

Claim 1

AN APPARATUS FOR CUTTING SHEET MATERIAL ALONG A RECTILINEAR LINE TRANSVERSELY OF ITS DIRECTION OF MOVEMENT, SAID APPARATUS COMPRISING A SUPPORT SURFACE FOR SUPPORTING THE MATERIAL TO BE CUT, A CUTTER, A MEANS FOR ROTATING THE CUTTER ABOUT AN AXIS PARALLEL TO SAID LINE OF MOVEMENT OF THE MATERIAL SO THAT SAID CUTTER PASSES TRANSVERSELY THROUGH THE MATERIAL ONCE DURING EACH REVOLUTION, SAID ROTATING MEANS INCLUDING AN ARM MOUNTED AT ONE END FOR ROTATION ABOUT SAID AXIS, A LEVER PIVOTED TO THE OTHER END OF SAID ARM, AND A SHAFT SUPPORTING SAID CUTTER SAID SLIDABLY MOUNTED ON SAID LEVER FOR LONGITUDINAL MOVEMENT IN REFERENCE THERETO; AND MEANS FOR ADDITIONALLY MOVING THE CUTTER TRANSVERSELY OF ITS AXIS OF ROTATION AND IN THE SAME DIRECTION AS THE MATERIAL DURING PASSAGE OF THE CUTTER THROUGH THE MATEREIAL, SAID MEANS FOR ADDITIONALLY MOVING THE CUTTER INCLUDING A FIRST STATIONARY CAM COACTING WITH SAID LEVER TO VARY THE PIVOTAL POSITION THEREOF IN REFERENCE TO SAID ARM DURING ROTATION OF THE ARM SO AS TO VARY CORRESPONDINGLY THE DISTANCE OF THE CUTTER FROM SAID AXIS, AND A SECOND STATIONARY CAM EXTENDING ACROSS THE MATERIAL TRANSVERSELY OF THE DIRECTION OF MOVEMENT THEREOF, SAID SECOND CAM ENGAGING ONE END OF SAID SHAFT TO EFFECT LONGITUDINAL MOVEMENT OF THE SHAFT DURING THE PASSAGE OF THE CUTTER THROUGH THE MATERIAL; THE RATE OF ROTATION OF THE CUTTER, THE RATE OF THE TRANSVERSE ADDITIONAL MOVEMENT OF THE CUTTER, AND THE RATE OF MOVEMENT OF THE MATERIAL BEING SO CORRELATED THAT THE MATERIAL IS CUT ALONG A LINE GENERALLY TRANSVERSE OF THE DIRECTION OF MOVEMENT OF THE MATERIAL.

Claim 2

AN APPARATUS FOR CUTTING SHEET MATERIAL ALONG A RECTILINEAR LINE TRANSVERSELY OF ITS DIRECTION OF MOVEMENT, SAID APPARATUS COMPRISING A SUPPORT SURFACE FOR SUPPORTING THE MATERIAL TO BE CUT, A CUTTER, A MEANS FOR ROTATING THE CUTTER ABOUT AN AXIS PARALLEL TO SAID LINE OF MOVEMENT OF THE MATERIAL SO THAT SAID CUTTER PASSES TRANSVERSELY THROUGH THE MATERIAL ONCE DURING EACH REVOLUTION, SAID ROTATING MEANS INCLUDING AN ARM MOUNTED AT ONE END FOR ROTATION ABOUT SAID AXIS, A LEVER PIVOTED TO THE OTHER END OF SAID ARM, AND A SHAFT SUPPORTING SAID CUTTER SAID SLIDABLY MOUNTED ON SAID LEVER FOR LONGITUDINAL MOVEMENT IN REFERENCE THERETO; AND MEANS FOR ADDITIONALLY MOVING THE CUTTER TRANSVERSELY OF ITS AXIS OF ROTATION AND IN THE SAME DIRECTION AS THE MATERIAL DURING PASSAGE OF THE CUTTER THROUGH THE MATEREIAL, SAID MEANS FOR ADDITIONALLY MOVING THE CUTTER INCLUDING A FIRST STATIONARY CAM COACTING WITH SAID LEVER TO VARY THE PIVOTAL POSITION THEREOF IN REFERENCE TO SAID ARM DURING ROTATION OF THE ARM SO AS TO VARY CORRESPONDINGLY THE DISTANCE OF THE CUTTER FROM SAID AXIS, AND A SECOND STATIONARY CAM EXTENDING ACROSS THE MATERIAL TRANSVERSELY OF THE DIRECTION OF MOVEMENT THEREOF, SAID SECOND CAM ENGAGING ONE END OF SAID SHAFT TO EFFECT LONGITUDINAL MOVEMENT OF THE SHAFT DURING THE PASSAGE OF THE CUTTER THROUGH THE MATERIAL; THE RATE OF ROTATION OF THE CUTTER, THE RATE OF THE TRANSVERSE ADDITIONAL MOVEMENT OF THE CUTTER, AND THE RATE OF MOVEMENT OF THE MATERIAL BEING SO CORRELATED THAT THE MATERIAL IS CUT ALONG A LINE GENERALLY TRANSVERSE OF THE DIRECTION OF MOVEMENT OF THE MATERIAL.
