Abstract: According to one aspect, the invention relates to a method of stacking covers for the fabrication of booklets. Each cover includes two cover sheets and an interconnecting spine. Applied to the inner surface of the spine is a binding device that includes a binding agent. The covers are mutually stacked with the inner surface of the spine of one cover lying against the outer surface of the spine of an adjacent cover. According to the invention, a deactivatable separating device is provided between the binding agent and the outer surface of the spine of an adjacent cover, so as to prevent adhesion between the spines of respective covers. According to another aspect of the invention, a cover of this kind is provided with a binding device that includes a binding agent (104) and a separating device (105) disposed on the surface of the binding agent that lies remote from the spine (103), this separating device preferably having a form of woven material affixed to the binding agent (104).

Abstract: The invention relates to a method and to a device for producing booklets, each of which comprises a cover (A) that has two cover sides, a spine between the cover sides, a glue string applied to the inner surface of the spine, and a sheet bundle inserted between the two cover sides. A plurality of covers each having an applied glue string are placed in the immediate vicinity of each other, in a readiness position. The sheet bundle (B) is then combined with one of the covers (A), so as to enclose the sheet bundle in the cover with one side edge of the bundle facing towards the glue string. The glue string is then actuated in an actuator (8), so as to bind this side edge of the bundle (B) to the inner surface of the spine. According to the invention, the sheet bundle (B) is combined with the cover (A) by moving the sheets of the bundle one by one, or as a complete bundle, to the cover in its readiness position by means of a powered transporter.
