US 4,194,832 A · Consecutive copying and bookbinding method and its apparatus

Abstract

Images of a microfilm on which images of the pages of a book are recorded are alternately and successively formed on an electrophotographic member for printing the obverse surface of a web and on another electrophotographic member for printing the reverse surface of the web. Then, these images formed are transferred and fixed onto the obverse and reverse surface of the web, thereby to complete printings of the respective pages of the book. Finally, the web with the printed images is folded at an interval of one page and the folded web is cut and bound. A consecutive copying and bookbinding apparatus comprises an electrophotocopying apparatus disposed on an image projection path of a microfilm projector provided with projection path changing mirror. Another electrophotocopying apparatus is disposed on a projection path normal to the aforesaid projection path. Rollers are provided to continuously feed the web past these electrophotocopying apparatuses. A folder folds the web with the images printed on both the surfaces at an interval of one page and a binder binds the folded web.

Dependent claims

A consecutive copying and book-binding method for manufacturing a book from a web and wherein individual pages of the complete book are imaged on individual frames of a microfilm, comprising the steps of:

(a) projecting an image of a frame of the microfilm on an endless electrophotographic plate, developing the latent image, transferring the image electrostatically to an obverse surface of the web at one location on the web, and fixing the image on the obverse surface of the web;
(b) projecting another image in the next frame of the microfilm on another endless electrophotographic plate, developing the latent image, transferring the other image electrostatically to a reverse surface of the web at a location displaced along the length of the web by a distance which is an integer multiple of the width of one page, and fixing the image on the reverse surface of the web;
(c) successively folding the web with the fixed images at intervals of one page after repeating steps (a) and (b) while advancing the web;
and
(d) cutting the final page of the book and binding the folded web.
