Abstract
Abstract The format of sheet material being printed is controlled and may be varied during successive printing cycles of a continuously operating printing machine by means of an assembly, preferably including a step-by-step motor for driving the sheet, which assembly is controlled by pulses and moves the sheet during a period within which no printing takes place.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
169 words
A printing device for printing spaced indicia on a moving band of material including means for defining printing and non-printing phases of machine operation comprising at least one rotatable printing element for printing indicia on the band, at least one counter pressure printing platen pivotally mounted about an axis for cooperating with said at least one printing element during the printing phase and having a curved surface for supporting the band, motor means for reciprocatingly pivoting said pivotally mounted platen, traction means mounted on said platen for engaging the band to move said band intermittently over the surface of said platen during the non-printing phase, a pulse generator for generating varying numbers of pulses in accordance with a program, a step by step motor operable by the pulses of said generator for actuating said traction means for moving varying lengths of the band over the surface of the platen during the non-printing phase in accordance with the number of pulses generated by the generator in accordance with the program.
Claim 2
Dependent Claim
169 words
A printing device for printing spaced indicia on a moving band of material including means for defining printing and non-printing phases of machine operation comprising at least one rotatable printing element for printing indicia on the band, at least one counter pressure printing platen pivotally mounted about an axis for cooperating with said at least one printing element during the printing phase and having a curved surface for supporting the band, motor means for reciprocatingly pivoting said pivotally mounted platen, traction means mounted on said platen for engaging the band to move said band intermittently over the surface of said platen during the non-printing phase, a pulse generator for generating varying numbers of pulses in accordance with a program, a step by step motor operable by the pulses of said generator for actuating said traction means for moving varying lengths of the band over the surface of the platen during the non-printing phase in accordance with the number of pulses generated by the generator in accordance with the program.
Claim 3
Dependent Claim
19 words
A printing device as claimed in claim 1 wherein said step by step motor is mounted on said platen.
Claim 4
Dependent Claim
31 words
A printing device as claimed in claim 1 wherein said traction means is provided with teeth means disposed forwardly and rearwardly of the surface of said platen for engaging said band.
Claim 5
Dependent Claim
20 words
A printing device as claimed in claim 1 wherein said platen has the form of a segment of a cylinder.
Claim 6
Dependent Claim
28 words
A printing device as claimed in claim 4, wherein the surface of said platen is substantially semi-cylindrical and the band is supported substantially entirely along the semi-cylindrical surface.
Claim 7
Dependent Claim
24 words
A printing device as claimed in claim 4 wherein the surface of said platen is substantially three quarters of the surface of a cylinder.
Claim 8
Dependent Claim
23 words
A printing device as claimed in claim 1 and further comprising a rotatable cylinder, said printing element being mounted on said rotatable cylinder.
Claim 9
Dependent Claim
23 words
A printing device as claimed in claim 7 wherein said motor means rotates said rotatable cylinder on which is mounted said printing element.
