Process and apparatus for continuously treating a web adapted to pass through a computer printer

Apparatus for feeding and continuously printing on a flexible deformable strip so as to produce a printed strip having thereon a plurality of repeating series of impressions, each series of impressions comprising a plurality of successive but non-overlapping different impressions each of which, when subsequently severed from the others, will comprise a sheet different from at least one contiguous sheet in the series, comprising a computer printer, means for passing the strip through the computer printer so as to mark on the strip a series of marks having the spacing of the different impressions subsequently to be printed on the strip, a plurality of printing stations through which the strip passes sequentially, said stations being each adapted to print a different impression on the strip, means individual to each said station for reading the marks placed on the strip by the computer printer, each said individual reading means reading said marks to determine whether its associated said printing station is or is not to be actuated, and means responsive to the reading of said marks for individually actuating said printing stations with such timing as to print on the strip said series of different non-overlapping impressions, one said series after another.
