Abstract
Loose-leaf binder cover has a unitary web of thermoplastic sheet material wrapped about and adhesively bonded to the opposite surfaces of a plurality of stiffener panel inserts with the longitudinal side edge of the sheet material being overlapped. The panels include a back panel and a pair of rectangular cover panels laterally spaced apart, one from the others. The upper and lower edges of the binder consist of portions of the sheet material turned over the edges of the panel inserts. The other edge portions of the sheet material disposed about the inserts are welded together to fully encase the panel inserts within the sheet material. At locations between adjacent inserts, opposed portions of the sheet material are also welded together to provide hinge lines for the binder between the back panel and cover panels thereof. The method of manufacturing the above described loose-leaf binder cover is also disclosed.
