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 (F) between the paper piece (Pa, Pb) without occurrence of jamming or other problem even if the paper (P) is extremely curled to have concave and convex deformations on its surface through printing or other process.
