Abstract: A forms decollator for separating superimposed continuous forms into separate plies has a pair of abrasive rolls rotatable in opposite directions away from one another and a separator roll bearing thereagainst and wholly supported thereby so that, together with the abrasive rolls, the forms may be separated as they are moved between the abrasive rolls and through the nips of the separator roll and each abrasive roll so as to be directed over guide elements and refolded over pack breakers which permit the separated plies to be neatly refolded. The guide elements have undercut portions near their terminal ends to avoid interference with the separated plies during the process of refolding.
