Abstract
Abstract An inserter system having an improved control system. The system includes a sheet inserter system and one or more web modules, for, receiving a web of forms, scanning the forms for information, storing and retransmitting the information, separating the web into discrete forms, and feeding the forms for further processing by the sheet inserter system. The sheet inserter system adds additional sheets to the forms inserts the batches so formed into envelopes and may imprint the envelopes with metered postage. The control system includes a supervisory controller which receives the control information and controls the sheet inserter system and web modules in accordance therewith. A buffer is provided to transfer control information from the supervisory controller to the sheet inserter system. The buffer receives control signals from the supervisory controller synchronously with the transfer of batches of documents from the web modules to the sheet inserter system but does not transmit the control signals to the sheet inserter system unless the transfer is successfully completed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
155 words
An inserter system comprising: a. a web means for assembling batches of forms, said forms including a control document in each of said batches, and for generating control signals associated with each of said batches in accordance with information imprinted on said control document; b. sheet inserter means responsive to said control signals for adding sheets to said batches of forms in accordance with said control signals; c. transfer means intermediate said web means and said sheet inserter means for transferring said batches from said web means to said sheet inserter means; d. detector means for detecting the transfer of said batches to said transfer means and for generating an output signal indicative of successful transfer; and, e. buffer means responsive to said detector means for receiving said control signals when transfer of said associated batch begins and transmitting said control signals to said sheet inserter if, and only if, said transfer is successfully completed.
Claim 2
Dependent Claim
155 words
An inserter system comprising: a. a web means for assembling batches of forms, said forms including a control document in each of said batches, and for generating control signals associated with each of said batches in accordance with information imprinted on said control document; b. sheet inserter means responsive to said control signals for adding sheets to said batches of forms in accordance with said control signals; c. transfer means intermediate said web means and said sheet inserter means for transferring said batches from said web means to said sheet inserter means; d. detector means for detecting the transfer of said batches to said transfer means and for generating an output signal indicative of successful transfer; and, e. buffer means responsive to said detector means for receiving said control signals when transfer of said associated batch begins and transmitting said control signals to said sheet inserter if, and only if, said transfer is successfully completed.
Claim 3
Dependent Claim
29 words
An inserter system as described in claim 1 wherein said web means comprises a plurality of web modules and assembles said batches of forms from a plurality of webs.
Claim 4
Dependent Claim
19 words
An inserter system as described in claim 1 wherein said web means and said sheet inserter means operate asynchronously.
Claim 5
Dependent Claim
19 words
An inserter system as described in claim 2 wherein said web means and said sheet inserter means operate asynchronously.
Claim 6
Dependent Claim
185 words
An inserter system as described in claim 3 wherein: a. said control signal comprises a plurality of bits, each of said bits indicating whether or not an associated feeder module should feed a sheet into said associated batch; b. said buffer means comprising first and second registers; c. said detector means comprises first and second detectors, said first detector being positioned to provide a first signal indicative of the beginning of transfer of said batch from said web means to said transfer means and said second detector being positioned to provide said output signal when said transfer to said transfer means is successfully completed; d. said buffer means is responsive to said first signal to load said bits into said first register and is responsive to said output signal to shift said bits from said first register to said second register; and, e. said sheet inserter means is responsive to said bits only after said bits are shifted to said second register, whereby said sheet inserter means will not attempt to add sheets to said associated batch unless said transfer of said batch is successful.
Claim 7
Dependent Claim
185 words
An inserter system as described in claim 4 wherein: a. said control signal comprises a plurality of bits, each of said bits indicating whether or not an associated feeder module should feed a sheet into said associated batch; b. said buffer means comprising first and second registers; c. said detector means comprising first and second detectors, said first detector being positioned to provide a first signal indicative of the beginning of transfer of said batch from said web means to said transfer means and said second detector being positioned to provide said output signal when said transfer to said transfer means is successfully completed; d. said buffer means is responsive to said first signal to load said bits into said first register and is responsive to said output signal to shift said bits from said first register to said second register; and, e. said sheet inserter means is responsive to said bits only after said bits are shifted to said second register, whereby said sheet inserter means will not attempt to add sheets to said associated batch unless said transfer of said batch is successful.
Claim 8
Dependent Claim
119 words
An inserter system as described in claim 5 wherein: a. said sheet inserter means operates cyclically, each batch in said sheet inserter means progressing to the next feeder module or to the output of said sheet inserter system and a new batch being transferred to said sheet inserter system during each cycle; b. said sheet inserter means generates a clock signal synchronous with said cycles; c. said buffer means is responsive to said clock to define a window during which said bits may be shifted from said first register to said second register, said window being defined by the period within said cycles during which said batches may be transferred from said transfer means to said sheet inserter means.
Claim 9
Dependent Claim
119 words
An inserter system as described in claim 6 wherein: a. said sheet inserter means operates cyclically, each batch in said sheet inserter means progressing to the next feeder module or to the output of said sheet inserter system and a new batch being transferred to said sheet inserter system during each cycle; b. said sheet inserter means generates a clock signal synchronous with said cycles; c. said buffer means is responsive to said clock to define a window during which said bits may be shifted from said first register to said second register, said window being defined by the period within said cycles during which said batches may be transferred from said transfer means to said sheet inserter means.
Claim 10
Dependent Claim
145 words
An inserter system as described in claim 7 wherein: a. said first detector detects the presence or absence of a batch at the input to said transfer unit and said first signal is generated by the trailing edge of the output of said first detector, indicating that said batch has passed said first detector; b. said second detector detects the presence or absence of said batch in said transfer means and said output signal is generated by logically adding the output of said second detector, the negated output of said first detector and said window; and, c. the trailing edge of the output of said second detector, indicating that said batch has been transferred from said transfer means to said sheet inserter means, generates a return signal to said web means to enable said web means to feed the next batch to said transfer means.
