Abstract: Method and apparatus for producing bound flat parts, each having a sheet stack. Method includes conveying unbound sheet stack from sheet stack dispensing device into cassette of circulating conveyor, so that sheet stack is received into cassette, after receiving sheet stack in the cassette, driving circulating conveyor so cassette with sheet stack is conveyed to binding apparatus, and binding sheet stack in cassette at binding apparatus so that fingers formed as binding tongues are disposed in perforations so fingers are curved in the shape of a spiral. At least one of: adhesive-free area of each finger brought into overlapping contact with area of respective finger, adhesive-free area of each finger brought into overlapping contact with area of respective finger provided with adhesive, and overlapping contact areas of fingers are bound together. Removing at a dispensing station bound sheet stack from cassette, and delivering empty cassette to sheet stack dispensing device.

Abstract: Method and apparatus for binding stacked flat parts, and bound stacked flat parts. The stacked flat parts are provided with perforations. The method includes coupling several individual fingers on an outer sheet, applying an adhesive to a predetermined area of the fingers, inserting the fingers into the perforations of the stacked flat parts, so that the fingers are bent in a spiral-like manner, and positioning an portion of each finger in overlapping contact with the predetermined area of respective fingers.

Abstract: A wire comb for binding stacked flat parts, a method of binding stacked flat parts with the wire comb, and a device for binding stacked flat parts with the wire comb. The wire comb includes loop-like or hairpin-like sections insertable into perforations formed in the flat parts, and wire sections arranged next to each other in a longitudinal direction that combine together the loop-like or hairpin-like sections. In an open state before insertion of the loop-like or hairpin-like sections into the perforations, the wire comb has a cross-section in which the loop-like or hairpin-like sections are straight on an insertion side and in which a side facing the straight loop-like or hairpin-like sections is bent or prerounded.

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.

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: An apparatus for converting a length of metallic or other wire into a series of successive helical wire binders and for threading successive binders into rows of holes in the spines of successive stacks of sheets at a binding station includes an elongated guide defining an at least substantially continuous path for the wire from a wire inserting station to the binding station. The guide includes a rotary convoluting tool at the inserting station and a stationary cylindrical worm coaxial with the tool and extending from the latter to the binding station. Successive foremost binders are threaded into the rows of holes in successive stacks at the binding station and are severed from the respective following binders by a set of knives when the threading steps are completed.
