Abstract
A contact-bonding film insertion device included in a contact-bonded paper manufacturing apparatus which produces releasable and expandable contact-bonded paper such as postcards (Q) by inserting a contact-bonding film (F) carried on a vertically movable support plate (51) between opposed paper pieces (Pa, Pb) of folded cut paper (P) by a paper pushing device (60), the cut paper (P) having been transferred by a paper transfer device (20) and folded by a paper folding device (30), and subsequently by extracting the support plate (51) from the paper piece (Pa, Pb) by a support plate extracting device (55) to supply the paper (P) into which only the contact-bonding film F is inserted to a paper contact-bonding device (70) and paper cutting device (80), a slope (51y) which is downward-inclined toward its tip to form substantially an acute angle at the tip is provided on a periphery (51x) of the support plate (51) included in the contact-bonding film insertion device, the periphery (51x) which includes the slope (51y) having a shape being preferably curved upward with respect to the main body of the support plate (51). This structure allows smooth insertion of the contact-bonding film (…
