Abstract: An apparatus for folding envelope blanks comprises a plurality of platform assemblies which are rotatably mounted on a base. The platform assemblies are incrementally advanced around the base, and separate mechanisms located around the periphery of the base perform the individual folding operations. Particular advantages are achieved by including the side flap folding mechanism on the platform assemblies so that the folded flaps are held firmly in place until the envelope is removed from the machine.

Abstract: A floppy disk burnishing and packaging machine and method including pick up, burnishing, packaging and collection assemblies. A transfer mechanism moves disks between the various assemblies and a control system coordinates the operation in each so that processing proceeds simultaneously in each according to a particular sequence. Disks are removed from a supply stack one at a time with part of that process involving curling the peripheral edge of the topmost disk upwardly away from the stack. The burnisher includes air knife hold down devices to force the disks against burnishing rolls over which burnishing tapes are moved. The air knife devices also cause a slight amount of wrapping between the disks and the burnishing rollers to increase the burnishing area. Further, the disk is oscillated during burnishing, relative to the burnishing rolls, to improve burnishing. Burnished disks are automatically packaged in protective jackets which are ejected and collected.

Abstract: Covers for floppy discs and like media are first formed with three sides sealed and thereafter the disc is inserted. A fourth flap must then be folded and glued for permanent sealing of the disc. The subject machine receives the unsealed cover with the disc inserted and folds and glues the flap to seal the disc in the cover.

Abstract: A one-piece molded clip for holding a tablet or sheets of paper on a clip board or other supporting structure and including a pencil or pen holder formed integrally with the clip. The clip has a base portion which may either be provided with openings for rivets to attach the clip to a supporting structure or with integrally formed studs. A spring is integrally formed with the base and consists of a first wall which projects upwardly from the base and a second wall which projects outwardly and downwardly and terminates in a gripper disposed beneath the plane in which the lower surface of the base lies to provide increased gripping power when the clip is attached to a surface. The pen or pencil holder consists of a slot defined by the upwardly projecting wall of the spring and another wall extending in spaced, approximately parallel relationship thereto.

Abstract: An album or similar book-like article having a flexible one-piece spine of extruded construction which includes a series of fingers extending the length of the spine and projecting from an inner surface thereof. A three ply, laminated page formed with the center ply shorter than the outer plies to provide a slot extending along one edge of the page is attached to each finger by gluing the fingers in the slots. The spine is provided with areas of reduced thickness extending longitudinally thereof intermediate each pair of fingers to provide increased flexiblity at these points and thereby allow the pages to lie flat when the album is open. Additionally, fasteners are provided for interconnecting two or more album units to form a composite album.

Abstract: A one-piece, molded plastic binder ring that may be formed with an integral post for attaching the binder ring to the spine of a loose leaf cover. The binder ring includes a T-shaped socket in its base which receives a cross bar of a flexible strap molded integrally with the base, and locking projections are formed in the socket to lock the strap cross bar in a pocket formed in lower surface of the base of the binder ring.
