Abstract
Abstract A mechanism for automatically feeding individual pre-cut sheets and stuffing a personalized letter or some other pre-cut insert into a personalized envelope. The mechanism has means to permit additional inserts to be automatically added to the envelope and to automatically seal the contents within the envelope. The mechanism will also combine pre-cut inserts and envelopes fed from different sources and form them into a completed mailing envelope.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
152 words
A mechanism for forming an article having at least one sheet having code data thereon comprising means for holding a stack of pre-cut single individual sheets, means for feeding each of said sheets individually from said stack of sheets, means for sequentially presenting a series of comparison data to said mechanism, reading means adjacent said stack for sensing said code data on each sheet before each sheet is fed from said stack, means for comparing the code data on each sheet sensed by the reading means with the then first, at the time of comparison, sequential series of comparison data to determine whether the code data on each sheet matches with said comparison data, means for interrupting feeding of sheets from said stack responsive to said comparing means for stopping the feed of a sheet from said stack if the code data on the sheet does not match with said comparison data.
Claim 2
Dependent Claim
152 words
A mechanism for forming an article having at least one sheet having code data thereon comprising means for holding a stack of pre-cut single individual sheets, means for feeding each of said sheets individually from said stack of sheets, means for sequentially presenting a series of comparison data to said mechanism, reading means adjacent said stack for sensing said code data on each sheet before each sheet is fed from said stack, means for comparing the code data on each sheet sensed by the reading means with the then first, at the time of comparison, sequential series of comparison data to determine whether the code data on each sheet matches with said comparison data, means for interrupting feeding of sheets from said stack responsive to said comparing means for stopping the feed of a sheet from said stack if the code data on the sheet does not match with said comparison data.
Claim 3
Dependent Claim
36 words
A mechanism as claimed in claim 1 wherein feeding means feed said sheets from the bottom of said stack and said reading means are located beneath said stack to read the lower-most sheet in said stack.
