Abstract
A rotary press product such as a newspaper is printed by continuously running one or more paper webs through printing rolls, and supplements are inserted into the product while the webs are running by applying an electrostatic charge to the surface of the running web after the web has been printed, delivering a supplement to the charged surface for electrostatic adhesion thereto, folding the web with the supplement adhering thereto, and then discharging any residual electrostatic charge from the folded product.
Claims14
The method of inserting supplements into a rotary press product wherein said product is produced by continuously running at least one elongated paper web from a supply roll through printing rolls, comprising the steps of applying an electrostatic charge to the surface of said running web subsequent to passage of the web through said printing rolls, delivering a series of supplements sequentially and in face-to-face relation to the charged running surface of said web for electrostatic adhesion of said supplements to said web while said web is still running, and thereafter folding successive portions of said web while said supplements are electrostatically adhered thereto to form at the conclusion of said folding step, folded rotary press products each of which has one of said supplements inserted therein.
