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.
