Photograph slide sleeving material is manufactured by cutting pocket opening slots in an elongated first web section of polymer film material as the web is continuously moved through a slot cutting station. The slotted first web section and an adjacent elongated second web section of polymer film material are continuously moved through a laminating station where they are laminated at locations forming pocket bottom walls and side walls. An elongated web of photograph slide sleeving material having a plurality of rows of pockets emerges from the laminating station and is continuously moved through a perforating station where it is perforated between adjacent rows of pockets. Ring binder storage files and hanging storage files are assembled by separating sheets of slide sleeving material from the elongated web and attaching storage mounts having adhesive edges.
