Abstract
Abstract An apparatus for detaching or separating completed multiply copy printed forms as they are discharged from an automatic printing or billing machine. The apparatus includes a main frame for supporting the printed forms and to which is attached a tensionapplying pair of rollers at one end and a carriage at the other. The carriage moves transversely across the main frame and severs the printed forms by pulling a cutting line therethrough as it moves across the main frame. The operation of the apparatus is synchronized with the operation of the printing machine and will route the detached form to a designated location.
