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). The invention also comprises a method of producing a booklet with the use of the inventive cover. According to the inventive method of fabrication, the separating device is deactivated at the same time as the binding agent is activated and a sheet bundle is moved in towards the spine of the cover.
