Abstract: The invention relates to a method for binding sheaves of papers into covers such as to form booklets, each booklet comprising a cover made up of two cover sheets, a spine therebetween, and a binding agent attached to the inside of the spine, as well as a sheaf of papers inserted in the cover, one side edge of the sheaf being connected to the inside of the spine. The binding takes place by means of the binding agent being activated by an activation device such that the edge of the sheaf of papers will be connected to the inside of the spine via the binding agent. Each cover acts on a sensing means, which senses the presence or non-presence of indication means connected to the cover and which actuates means for influencing the further course of the method. The invention also relates to a cover provided with indication means sensed in the above described manner.

Abstract: In a flat gathering binding system it is necessary to use a cover breaker to apply pressure to the book and cover to form a sharp square fold on each side. A cover breaker control system includes a motor which is coupled to a cover breaker carriage for varying the relative position of first and second movable cover breaker plates which are used to apply the pressure. A controller calculates the difference between book thickness which the plates are set for and a desired thickness, and is operable to vary the relative positioning by a distance corresponding to this difference so that when the plates are driven to break the cover they are spaced a distance apart according to the desired thickness.

Abstract: A sheet binding apparatus, for attaching loose sheets to one or more folders, has a completely automatic binding process after insertion of the folder(s). This is carried out by a heating assembly, the current supply to which is controlled by a micro-processor having inputs received from a starter device of light detector type, a temperature detector device of thermistor type and a timer device. The timer device is activated by the micro-processor when the temperature detector device indicates working temperature at the heating assembly. In one aspect of the binding process it is also related to the thickness of the folder(s) to be bound. This is carried out by a current control device acting on the supply circuit for the heating assembly in such a way that the thicker the folders inserted, the more current is allowed to the heating assembly.

Abstract: A book sewing machine has an inserter for plates for indicating the planes of separation between the books. Each plate is disposed in the separation plane in correspondence with the top of the adjacent face of the contiguous books on that side of the books facing the loader. The machine also has a gluer for applying a layer of glue to the backs of the books which advance towards the discharge zone. Close to the latter is a separator constituted by a cutting blade which traverses the pile of books so that it cuts the layer of glue on the backs and simultaneously cuts the thread connecting the last book to the next book, thus effecting the separation. An operating cycle of the separator device is started each time a control circuit is given an enabling signal by a detecting device for detecting the passage of a plate. The position of the detection device preferably coincides with that of the cutting blade which may be a separate element or which may be part of the plate.

Abstract: An automatic machine for perforating and comb binding blocks of loose sheets. The control of the movements of the punching and binding mechanisms is centralized. The machine is capable of making perforations and thus bindings which are either continuous or in the form of portions separated in a manner which can be preset as desired. Feed of the sheets to be perforated and bound is effected by chains provided with fixed brackets with corresponding movable tabs which can withdraw into or project out of the conveying surface. The movement of the tabs is coordinated with that of the chains and of the punching mechanism. The feed of the comb binding to the coupling station is effected by two independent brake-friction units, controlled separately by presettable digital controls.

Abstract: In a booklet binding machine a flat cover signature is added in leading edge register to a single or collated signatures moving in a travel path prior to saddle folding. The signatures are passed as a unit to a stitching station to be jogged and center stitched. Overlapping pairs of arbor mounted rotary slitting blades at opposing sides of the travel path head and tail trim the signatures during its movement by feed rollers between the pairs of slitting blades. The uppermost arbor and blades are angularly rotated at a greater speed than the lowermost blades to insure a clean cut of the signatures. Cooperating presser rings on the arbors cooperate with the slitting blades prevent buckling of the signatures and strip tail-out of the trimmed edges thereof. Bearings mounting the uppermost presser rings on the upper arbor allow the uppermost rings to rotate at the rate of travel of the lowermost rings.

Abstract: A bookbinding machine which comprises a reference plate, an adhesive applicator, a cover applicator and a milling device. The adhesive applicator and the cover applicator are arranged on one side of the reference plate while the milling device is arranged on the opposite side thereof. A clamping device clamps a plurality of piled sheets of paper to be bound into a book standing on its edge surface or back on the reference plate. A selector is provided so as to selectively move the clamping device from above the reference plate in either of the two opposite directions. When the clamping device has been moved to the milling device, a controller causes the clamping device to return from the milling device to the reference plate, where the clamping device temporarily releases the book so as to adjust the level of the back of the book to that of the reference plate and clamps the book again to carry it to the adhesive applicator and then to the cover applicator and finally back to the reference plate.

Abstract: The present invention is directed to a process for determining the thickness of adhesive layers placed on book block backings by initially measuring the position of a backing before adhesive is applied to establish a reference point, applying adhesive, then measuring the position of the backing with adhesive to determine the thickness of the adhesive layer. Distances to a standard reference plane may be measured both before and after application of the adhesive, and the differences in respective positions may be used to determine thickness of the adhesive layer. Two such measurements before and after adhesive application are recommended, with the readings averaged to give a mean thickness of the adhesive layer. Measurements are preferably carried out by means of laser beam technology, with the aid of a beam splitter.
