Abstract:
A method of fabricating booklets, each of which compromises a cover having two cover sides, a spine located therebetween, a glue string applied to an inner surface of the spine, and a sheet bundle that is inserted between the two cover sides and that has one side edge affixed to the inner surface of the spine by means of the glue string, comprising:placing a plurality of covers with applied glue strings in an immediate proximity of each other in a readiness position, wherein the covers are disposed in a cassette in a state that is symmetrical in relation to a vertical plane through the cover spine;transporting to the covers, one by one or as a complete bundle and by means of a powered transporter, sheets that are to form the sheet bundle;moving said sheets, along a plane that is the symmetry plane of the cover through its spine, into contact with the cover fixed in said readiness position;combining said sheet bundle with one of the covers such as to enclose the sheet bundle with said side edge of the bundle facing towards the glue string; andmoving the cover containing said sheet bundle past an actuator that actuates the glue string so as to bind said bundle side edge to the inner surface of the spine.
