Abstract: Unstrapping apparatus for removing a strap (2) from a pack of sheets (1) initially contained in the strap is described. The apparatus comprises an input station including a blade (31) for cutting the strap (2) and a hook (59) for engaging the cut strap and carrying the strap to an association station (72). A feed transfer module (79) passes the unstrapped sheets to a doubles detect system and an authentication system (81, 83) for sorting the sheets into acceptable and unacceptable sheets. Unfit sheets, as determined by the doubles detect and authentication systems (81, 83) are transported to the association station (72) where they are stapled by a stapler (73) with the strap (2).
