Title: Stationery printing apparatus for continuous business forms stationery assemblies
Claims: I claim: 1. Stationery printing apparatus for printing indicia at a predetermined position on each form length of continuous business forms stationery assemblies formed of at least one elongated web of stationery separated into said form lengths by transverse, equally spaced lines of weakening, said apparatus comprising: a rotary printing roll having N equally circumferentially spaced printing surfaces thereon, said surface or surfaces being radially spaced from the axis of rotation of the roll a distance equal to NL/2.pi., where L is the distance between two adjacent transverse lines of weakening, and N is an integer equal to 1 or greater, impression means associated with said roll to define a printing nip so that continuous business forms passing through said nip will be imprinted upon by said printing surface at said nip, means for conveying a continuous business forms assembly along a path of stationery travel extending through said nip including a drive mechanism forwardly of said nip for positively advancing stationery along said path to said nip at a desired linear velocity, means for rotating said roll such that said printing surface is rotated at an angular velocity equal to said linear velocity, at least one first lineup indicia located along said path and forwardly of said nip, a second lineup indicia operatively associated with said roll whereby said roll may be initially located at a predetermined angular position about its axis of rotation, said first indicia being spaced from said nip by a distance D.sub.1, and said second indicia being positioned such that when said roll is in said predetermined angular position said printing surface will be angularly spaced from said nip by a distance D.sub.2, and wherein D.sub.1 is related to D.sub.2 as follows: D.sub.1 = D.sub.2 .+-. nL - X where n is zero or an integer of 1 or greater, and X is the longitudinal distance, if any, between said predetermined position on a form length and an arbitrarily selected index point, if any, on the form length to be aligned with said first lineup indicia, whereby when said roll is located in said predetermined angular position using said second indicia and a continuous business forms assembly having forms with individual lengths equal to L is initially positioned with said predetermined position or the arbitrarily selected index point, if any, of one of the form lengths adjacent said first indicia, upon operation of said conveying means, the form lengths will be imprinted upon at said predetermined positions thereon. 2. Stationery printing apparatus according to claim 1 and further including means adjustably mounting said lineup indicia for selective, adjustable movement relative to said printing surface. 3. Stationery printing apparatus according to claim 2 wherein said adjustable mounting means is secured to said printing roll. 4. Stationery printing apparatus for printing indicia at a predetermined position on each form length of continuous business forms stationery assemblies formed of an elongated series of interconnected individual business forms, each of equal length, said apparatus comprising: a rotary printing roll having at least one printing surface thereon; impression means associated with said roll to define a printing nip so that a continuous business forms assembly passing through said nip will be imprinted upon by said printing surface at said nip, means for moving a continuous business forms assembly along a path of stationery travel extending through said nip including a drive mechanism forwardly of said nip, means for rotating said print roll in timed relation with said moving means, at least one first lineup indicia located along said path and forwardly of said nip, a second lineup indicia associated with said roll whereby said roll may be initially located at specific predetermined location about its axis of rotation, said first and second indicia being located along said path and on said roll, respectively, such that when said roll is in said predetermined location, and a predetermined point on a continuous business forms assembly in said path is aligned with said first indicia, upon operation of said moving means, the form lengths will be imprinted upon at said predetermined position thereon. 5. The stationery printing apparatus of claim 4 further including means mounting one of said first and second indicia for adjustable movement with respect to said nip. 6. The stationery printing apparatus of claim 5 wherein said moving means is operative to drive a continuous business forms assembly along said path at a desired linear velocity and said rotating means is operative to rotate said roll such that said printing surface moves an an angular velocity equal to said linear velocity. 7. Stationery printing apparatus for printing indicia at a predetermined position on each form lenth of continuous business forms stationery assemblies formed of an elongated series of interconnected individual business forms, each of equal length, said apparatus comprising: printing means having at least one printing surface cyclically movable through a closed path including a printing position; means for moving a continuous business forms assembly along a path of stationery travel extending throuh said printing position and including a drive mechanism forwardly of said printing position; means for moving said printing surface in timed relation with said continuous business forms assembly moving means; at least one first lineup indicia located along said path of stationery travel and forwardly of said printing position; a second lineup indicia associated with said printing means whereby said printing surface may be initially located at a specific predetermined location in said closed path; and means mounting one of said first and second indicia for relative adjustable movement with respect to said printing position whereby said first and second indicia may be oriented with respect to said printing position such that when said printing surface is in said predetermined location, and a predetermined point on a continuous business forms assembly in said path of stationery travel is aligned with said first indicia, upon movement of a forms assembly, the form lengths will be imprinted upon at said predetermined positions thereon. 8. Stationery printing apparatus according to claim 7 wherein said mounting means mounts said second indicia for said adjustable movement. 9. Stationery printing apparatus for printing indicia at a predetermined position on each form length of continuous business forms stationery assemblies formed of an elongated series of interconnected individual business forms, each of equal length, said apparatus comprising: a printing device having N equally spaced printing surface movable through a closed path therewith, said closed path extending through a printing position and having a length equal to NL wherein N is an integer equal to 1 or greater and L is the length of each individual form in the continuous business forms stationery assembly; means for conveying a continuous business forms assembly along a path of stationery travel extending through said printing position and including a drive mchanism forwardly of said printing position for positively advancing stationery along said path of stationery travel to said printing position at a desired linear velocity, means for moving said printing surfaces at a velocity through said closed path equal to said linear velocity whenever said drive mechanism is operative; at least one first lineup indicia located along said path of stationery travel and forwardly of said printing position; a second lineup indicia operatively associated with said printing means whereby said printing surface may be initially located at a predetermined location in said closed path; said first indicia being spaced from said printing position by a distance D.sub.1, said second indicia being positioned such that when said printing surface is in said predetermined location in said closed path, said printing surface will be spaced from said printing position along said closed path by a distance D.sub.2, and wherein D.sub.1 is related to D.sub.2 as follows: D.sub.1 = D.sub.2 .+-. nL - X where: n is zero or an integer of 1 or greater, and X is the longitudinal distance, if any, between said predetermined position on a form length and an arbitrarily selected index point, if any, on the form length to be aligned with said first lineup indicia, whereby when said printing surface is located in said predetermined location using said second indicia and a continuous business forms assembly having forms with individual lengths equal to L is initially positioned with said predetermined position or the arbitrarily selected index point, if any, of one of the form lengths adjacent said first indicia, upon operation of said conveying means, the form lengths will be imprinted upon at said predetermined positions thereon.
