Abstract
Abstract Printing apparatus which receives printing stock in roll form, withdraws a predetermined amount of material from the roll, cuts the withdrawn material to provide a sheet of stock for printing, and then feeds the sheet to a printer. The printing apparatus can overprint onto sheets which are cut from a roll of preprinted stock, or can print on sheets which are measured and cut from blank roll stock. When used with preprinted stock including a printed material code, the printing apparatus reads the material code to verify that the proper printing stock is being used, and automatically interrupts the printing operation if the proper stock is not present.

Claim 1
Independent Claim
328 words
Apparatus for providing printed sheets from a continuous web of printing stock, comprising: support means to receive and dispense a continuous web of printing stock; means operative to receive the continuous web of stock from said support means and selectively operative to withdraw a length of said stock from the continuous web; means responsive to the passage of stock withdrawn from the continuous web to provide a first signal condition indicating that a certain length of stock has been withdrawn from the continuous web; stock cutting means positioned in operative relation to said stock withdrawn from the continuous web and operative in response to said first signal condition to cut said certain length of stock from the web to furnish a separate sheet of said stock; means operative to provide a second signal condition indicating that said stock cutting means has operated; printing means positioned to serially receive said separate sheet cut from the continuous web by said cutting means and operative in response to said second signal condition to perform a printing operation on said separate sheet; said means responsive to the passage of withdrawn stock being operative to measure the length of stock withdrawn from the continuous web and to provide said first signal condition when the measured length corresponds to a previously determined length for said separate sheet; said means responsive to the passage of withdrawn stock comprising pulse generating means operative to generate a pulse signal in response to passage of each increment of withdrawn web, said increment of length being less than said previously determined length for said separate sheet; counting means operative to maintain a pulse count signal condition in response to said pulse signals from said pulse generating means; and comparator means responsive to said pulse count signal condition and to a present reference count signal condition to provide said first signal condition when the pulse count corresponding to said pulse count signal condition is equal to said reference count signal.

Apparatus for providing printed sheets from a continuous web of printing stock, comprising: support means to receive and dispense a continuous web of printing stock; means operative to receive the continuous web of stock from said support means and selectively operative to withdraw a length of said stock from the continuous web; means responsive to the passage of stock withdrawn from the continuous web to provide a first signal condition indicating that a certain length of stock has been withdrawn from the continuous web; stock cutting means positioned in operative relation to said stock withdrawn from the continuous web and operative in response to said first signal condition to cut said certain length of stock from the web to furnish a separate sheet of said stock; means operative to provide a second signal condition indicating that said stock cutting means has operated; printing means positioned to serially receive said separate sheet cut from the continuous web by said cutting means and operative in response to said second signal condition to perform a printing operation on said separate sheet; said means responsive to the passage of withdrawn stock being operative to measure the length of stock withdrawn from the continuous web and to provide said first signal condition when the measured length corresponds to a previously determined length for said separate sheet; said means responsive to the passage of withdrawn stock comprising pulse generating means operative to generate a pulse signal in response to passage of each increment of withdrawn web, said increment of length being less than said previously determined length for said separate sheet; counting means operative to maintain a pulse count signal condition in response to said pulse signals from said pulse generating means; and comparator means responsive to said pulse count signal condition and to a present reference count signal condition to provide said first signal condition when the pulse count corresponding to said pulse count signal condition is equal to said reference count signal.

Apparatus for providing printed sheets from a continuous web of printing stock, comprising: support means to receive and dispense a continuous web of printing stock; means operative to receive the continuous web of stock from said support means and selectively operative to withdraw a length of said stock from the continuous web; means responsive to the passage of stock withdrawn from the continuous web to provide a first signal condition indicating that a certain length of stock has been withdrawn from the continuous web; stock cutting means positioned in operative relation to said stock withdrawn from the continuous web and operative in response to said first signal condition to cut said certain length of stock from the web to furnish a separate sheet of said stock; means operative to provide a second signal condition indicating that said stock cutting means has operated; printing means positioned to serially receive said separate sheet cut from the continuous web by said cutting means and operative in response to said second signal condition to perform a printing operation on said separate sheet; sensing means selectively responsive to coded variable indicia which may be disposed on the continuous web and which corresponds to a particular kind of web material, said sensing means providing a code signal condition in response to a sensed coded indicia which differs from a predetermined coded indicia; circuit means operative in response to said code signal condition to interrupt the operation of said web withdrawing means, said circuit means including a switching means which normally assumes an operative state for a certain time in response to said first signal condition from said means responsive to withdrawn stock; said switching means being operative during said certain time to enable said sensing means to be responsive to said coded variable indicia; and said switching means being responsive to said code signal condition to become latched to said operative state irrespective of said certain time.
