Claim 1
Independent Claim
298 words
IN THE PROCESS OF TRANSFERRING A SUCCESSION OF FLAT OBJECTS BY HOLDING SAID FLAT OBJECTS ON THE OUTER SURFACE OF A ROTATING CYLINDER SO AS TO IMPART A FORWARD MOTION TO SAID OBJECTS AND ROTATING SAID CYLINDER PAST STRIPPER MEANS INTERVENING BETWEEN THE FORWARD EDGES OF SAID OBJECTS AND THE SURFACE OF SAID CYLINDER SO AS TO REMOVE SAID OBJECTS FROM THE SURFACE OF SAID CYLINDER, A CONTINUOUS DELIVERY METHOD WHICH COMPRISES: APPLYING A VACUUM TO A FIRST SAID FLAT OBJECT AT A POINT LOCATED BEYOND SAID STRIPPER MEANS AND SPACED AWAY FROM SAID OUTER SURFACE OF SAID CYLINDER AS SAID FIRST OBJECT IS REMOVED BY SAID STRIPPER MEANS, SO AS TO FORCE THE MAJOR FORWARD PORTION OF SAID FIRST OBJECT AGAINST SAID STRIPPER MEANS BY THE FORCE OF SAID VACUUM, THEREBY SUBSTANTIALLY STOPPING THE FORWARD MOTION OF SAID FIRST OBJECT AND BENDING THE MINOR REAR PORTION OF SAID FIRST OBJECT AWAY FROM CONTACT WITH THE OUTER SURFACE OF SAID CYLINDER; HOLDING A SECOND FLAT OBJECT ON THE OUTER SURFACE OF SAID CYLINDER; ROTATING SAID CYLINDER PAST THE MINOR REAR PORTION OF SAID FIRST OBJECT AND SAID STRIPPER MEANS SO AS TO INTERPOSE SAID SECOND OBJECT BETWEEN THE OUTER SURFACE OF SAID CYLINDER AND THE MINOR REAR PORTION OF SAID FIRST OBJECT; FURTHER ROTATING SAID CYLINDER PAST SAID STRIPPER MEANS SO AS TO REMOVE THE MAJOR FORWARD PORTION OF SAID SECOND OBJECT FROM THE SURFACE OF SAID CYLINDER AND SO AS TO INTERPOSE THE MAJOR FORWARD PORTION OF SAID SECOND OBJECT BETWEEN THE MAJOR FORWARD PORTION OF SAID FIRST OBJECT AND SAID STRIPPER MEANS, THEREBY RELEASING SAID FIRST OBJECT FROM SAID APPLICATION OF VACUUM; APPLYING SAID VACUUM TO THE MAJOR FORWARD PORTION OF SAID SECOND OBJECT; AND CONTINUING SAID METHOD WITH A PLURALITY OF SUCCEEDING SAID FLAT OBJECTS.

Claim 3
Dependent Claim
207 words
IN AN APPARATUS FOR TRANSFERRING A SUCCESSION OF FLAT OBJECTS WHICH INCLUDES A ROTATABLE CYLINDER, MEANS FOR HOLDING FLAT OBJECTS ON THE OUTER SURFACE OF SAID CYLINDER AND MEANS FOR ROTATING SAID CYLINDER SO AS TO IMPART A FORWARD MOTION TO OBJECTS SO HELD, THE COMBINATION OF: STRIPPER MEANS HAVING ONE END LOCATED CLOSELY ADJACENT THE OUTER SURFACE OF SAID CYLINDER SO AS TO BE CAPABLE OF INTERVENING BETWEEN SAID SURFACE AND FLAT OBJECTS HELD ON SAID SURFACE, THEREBY BEING CAPABLE OF RREMOVING THE MAJOR FORWARD PORTIONS OF SAID OBJECTS FROM SAID SURFACE AS SAID CYLINDER IS ROTATED, SAID STRIPPER MEANS EXTENDING AWAY FROM THE OUTER SURFACE OF SAID CYLINDER AT AN ANGLE GREATER THAN TANGENCY THERETO; AND VACUUM MEANS APPLYING A VACUUM TO SAID OBJECTS TO FORCE SAID OBJECTS AGAINST SAID STRIPPER MEANS, SAID VACUUM MEANS BEING LOCATED ADJACENT TO AND SPACED FROM SAID CYLINDER SO AS TO BE CAPABLE OF SUBSTANTIALLY STOPPING THE FORWARD MOTION OF SAID OBJECTS BEING REMOVED FROM THE OUTER SURFACE OF SAID CYLINDER BY SAID STRIPPER MEANS AND SO AS TO BE CAPABLE OF HOLDING THE MAJOR FORWARD PORTIONS OF SAID OBJECTS SO THAT THE MINOR REAR PORTIONS OF SAID OBJECTS ARE BENT AWAY FROM THE OUTER SURFACE OF SAID CYLINDER.
