Abstract 1. A printing press having means by which legends are printed on a plurality of areas of paper travelling as a web with continuous motion through the press, guide means that fold the web back on itself along a fold line to bring the printed areas into superimposed relation with one another as successive page of a publication and with corresponding edge portions of the pages in register with one another while the pates move with continuous motion, the printing press also including means for printing on a second web of paper, the printing means of the web press including printing stations each having a cylinder that rotates in contact with a web to print the legends on the travelling web, and other guide means for bringing the second web of paper into contact with the first web at a location to be inserted by said one guide means into nesting relation with the fold of the first web for providing additional pates of said publication in register with the edges of the pages formed by the folding of the first web, means located along the course of movement of the registering edge portions of the paper pages including a welding station at a location where the paper webs are in contact with one another along said fold line and with printed areas of the different webs superimposed, the welding station having a heater located adjacent to said fold line adapted to weld the nested pages together only along said fold line as said edge portions pass said welding station, said heater being in position for heating corresponding registering edge portions and having a heat transfer rate coordinated with the speed of travel of the paper and a severing station to transversely cut superimposed webs into separate reproductions of the printed matter.
