Wrapping apparatus for use in the production of book covers employs wrapping systems for folding an overlay sheet around the leading and trailing edges of a cover board and subsequently clamping the folded-over overlay and cover board together for a defined period of time. The wrapping systems each comprise a tiltably mounted wrapping rail, controlled in a displacement-dependent mode, which cooperates with an associated support rail to form a clamp.
