Abstract: A bookbinding apparatus includes a sheet aligning unit which stacks and aligns plural sheets having holes formed therein, a binding mechanism which binds the sheets aligned in the sheet aligning unit by conveying a binding component in an axial direction while rotating the binding component in a circumferential direction, a binding component storing unit which stores therein plural binding components; a binding component conveyance path which conveys the binding component from the binding component storing unit to the binding mechanism. The binding component conveyance path forms a curved conveyance path for conveying the binding component with being curved with respect to the axial direction to an end portion of a side of the aligned sheets at which the binding mechanism starts inserting the binding component, at a position that is distant from the end portion by a distance smaller than a length of one binding component.

Abstract: A method and device for attaching and detaching material to a c-channel groove without requiring tools and without needing to access an end of the c-channel. The device comprises a coil-shaped element that is resiliently compressible and connected to a desired material. Through biasing or twisting the coil-shaped element, it is insertable at any point along a c-channel groove. The coil-shaped element is secured within the c-channel groove against separation therefrom through friction. A portion of the coil-shaped element can be extended outside of the c-channel groove for easy removal.

Abstract: Described is a device and a procedure to twist a coil into perforations that are provided in the margin sections of flat components, sheets of paper in particular, with a drive that causes the rotation and axial in-feed of the coil, corresponding to the inclination of its helix shape. With a stopping device the coil is inhibited from moving further and a release brings the coil out of contact with the stopping device and into contact with the drive.

Abstract: Sheets of paper are commonly held together with a spiral coil, which coil is inserted by a machine with at least one rotating spindle thereon. The spindle receives a spiral binder in a male to female relationship. As the spindle rotates the spiral binder, the spiral binder feeds into a stack of sheets having the appropriate apertures to receive the spindle and bind the pages together.

Abstract: Apparatus for introducing magnetic spirals into rows of neighboring perforations in the spines of stacks of overlapping sheets which are to form discrete calendars, memo pads or analogous commodities employs an elongated guide for a continuous magnetic coil spring. The coil spring is rotated about its longitudinal axis and is moved lengthwise so that its convolutions enter successive perforations of the row of perforations in the stack being held in the guide. The guide embodies or cooperates with magnets which maintain the convolutions of the coil spring in the path defined therefor by the guide. The magnets can be embedded in antimagnetic tubes forming part of or constituting the guide.

Abstract: The automated machine includes exchangeable spacing assemblies from which the positions of the various rollers, as well as the curve of the perforations in the stack(s) of sheets are determined for a spiraling a given coil size into the stack of sheets. Various sizes of spacing assemblies are provided to allow the operator to the binding machine to bind various sizes of coils into a stack of sheets by exchanging the spacing assemblies. Two support surfaces support the halves of thick books, the coil spiraling through stacks of sheets positioned on both support surfaces simultaneously. The stack(s) of sheets with a coil inserted therethrough drops to a crimping station when the rollers separate and the support surfaces pivot toward a vertical position. Once the crimping operation has been performed, an ejector ejects the book from the crimping station, and book exits the machine under the force of gravity.
