Abstract: The method and the apparatus of the invention serve to shift at least some sheets of successive stacks of overlapping sheets so that the originally straight holes which are provided along one marginal portion of each stack are converted into arcuate passages adapted to more readily receive the convolutions of spirals serving to pivotably couple the sheets of the stacks to each other. This is accomplished by inserting into one or both ends of some or all of the holes a discrete pin-shaped displacing member which is thereupon pivoted to thus shift at least some of the sheets relative to the neighboring sheets. In order to speed up the shifting of sheets, the displacing member or members is or are pivoted during withdrawal from the respective hole or holes to move its or their tips along arcuate paths at least approximating the curvatures of the convolutions which are to be introduced into the thus converted holes.

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: A binding apparatus facilitates a convenient, one-stage load-and-close binding system. The apparatus has a base and a pivotable former door movable between open and closed positions. A series of hooks are provided to hold an open binder relative to the base for loading sheets onto the open binder ringlets. The apparatus has three former surfaces or bars, including parallel, opposed first and second former bars, as well as an adjacently-positioned third former bar oriented generally perpendicularly to the first and second former bars. Generally, the binding apparatus operates to squeeze a wire binder between the opposed first and second forming bars to close the wire ringlets. The free ends of the wire ringlets are maintained in proper alignment against the third former bar.

Abstract: A spiral coil is used when stacking a plurality of sheets each having a plurality of holes punched at a constant pitch, and binding the sheets by inserting the spiral coil therethrough. The spiral coil has a different pitch from that between the holes of the sheets. The spiral coil may be densely wound or have a different pitch from that of the sheets. A bookbinding device is prepared for inserting the spiral coil through the holes in the sheets. The bookbinding device has the same pitch as that between the holes, and has an engaging portion at an end thereof for engagement with the spiral coil. The bookbinding device is inserted through the holes such that the spiral coil follows it and is plastically deformed, thereby binding the sheet. The spiral coil after the plastic deformation is held at a pitch after the deformation.

The coil leading guide has the same pitch as the interval between the holes, and is coupled to the densely spiraled coil through an engaging portion formed in an end portion of the coil leading guide. The coil leading guide is spirally inserted through the holes such that the densely spiraled coil follows the coil leading guide, whereby the plurality of sheets are bound 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: A binding machine and method for spirally binding a sheaf of papers into a book uses an adjustable speed drive to rotate a flexible plastic spiral element into respective holes in the book. The book has a plurality of holes in a row adjacent one edge of the book to receive the leading edge of the spiral bonding elements. A cylindrically shaped mandrel is spaced apart from a glidable block. The plastic pre-formed spiral binding element is fed onto the mandrel from the distal end thereof, with the leading edge of the binding element facing and spaced apart from the book. A pair of leading edge spreaders, one of which has a guidance groove, engages the plastic spiral to spread its coils just enough to permit it to enter the successive holes of a sheaf to be bound. A trailing spreader at the opposite end insures that the last hole is accommodated with a portion of the spiral coil.
