Abstract
Abstract Disclosed is an alignment assembly for accurately aligning separate sets of documents being inserted into the assembly from transversely oriented feed paths, the alignment assembly including a pivotally mounted document gate which provides not only guide passageways for documents entering the assembly, but also an alignment edge for accurately positioning and aligning documents within the assembly in document clamps adapted to transport the documents from the alignment assembly to a print station and thereafter to an exit transport assembly. The movement of documents inserted in the alignment assembly is effected by a document aligner assembly comprising cooperating vibratory document transporters and pivotally mounted back-up rollers for simultaneously urging the documents into the clamps and against the alignment edge of the document gate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
164 words
Alignment apparatus for aligning separate sets of documents wherein at least one of said sets includes documents such as conventional envelopes, said apparatus disposed at the intersection of transversely oriented first and second transport paths along which said sets of documents are respectively transported for aligning respective ones of said documents in a document engaging means of a transport assembly with said document engaging means positioned substantially perpendicular to said first one of said transport paths, comprising: a. document guide edge means disposed in an orientation substantially perpendicular to said document engaging means and parallel to said first transport path; b. a document support plate defining respective first and second passageways in communication with said first and second transversely oriented transport paths, respectively; and c. means for advancing a document from either of said sets of documents along said support plate simultaneously toward said document guide edge means and said document engaging means, thereby to accurately align said documents with said document engaging means.
Claim 2
Dependent Claim
164 words
Alignment apparatus for aligning separate sets of documents wherein at least one of said sets includes documents such as conventional envelopes, said apparatus disposed at the intersection of transversely oriented first and second transport paths along which said sets of documents are respectively transported for aligning respective ones of said documents in a document engaging means of a transport assembly with said document engaging means positioned substantially perpendicular to said first one of said transport paths, comprising: a. document guide edge means disposed in an orientation substantially perpendicular to said document engaging means and parallel to said first transport path; b. a document support plate defining respective first and second passageways in communication with said first and second transversely oriented transport paths, respectively; and c. means for advancing a document from either of said sets of documents along said support plate simultaneously toward said document guide edge means and said document engaging means, thereby to accurately align said documents with said document engaging means.
Claim 3
Dependent Claim
40 words
The apparatus as defined by claim 1 including document gate means mounted to pivot into and out of blocking engagement with said second passageway along which said envelopes are transported, said document gate means including said document guide edge means.
Claim 4
Dependent Claim
25 words
The apparatus as defined by claim 2 wherein said document gate means includes means defining a document channel in alignment with both of said passageways.
Claim 5
Dependent Claim
38 words
The apparatus as defined by claim 3 wherein said document support plate has a portion recessed relative to the remainder of said plate and said document gate means is adapted to pivot into engagement with said recessed portion.
Claim 6
Dependent Claim
48 words
The apparatus as defined by claim 1 wherein said advancing means comprises a document aligner assembly including vibrating transporter means disposed below and extending through openings in said document support plate and a cooperating roller assembly pivotally movable toward and away from engagement with said document transporter means.
Claim 7
Dependent Claim
23 words
The apparatus as defined by claim 5 wherein said vibrating transporter means are skewed at an angle toward said document guide edge means.
Claim 8
Dependent Claim
19 words
The apparatus as defined by claim 6 wherein said roller assembly is spring biased toward said vibrating transporter means.
