Method and unit for banding groups of bank notes

Abstract

A stack of bank notes with substantially parallelepiped shape and a defined stacking axis is formed by a forming machine and fed by a gripper to a banding unit equipped with a part which receives and grips each stack, which operates in conjunction with a banding machine for the application of a pair of first retaining bands, each wrapped around the stack at its opposite ends and at least one second retaining band which is wrapped around the stack in such a way that it is in contact with two transversal surfaces and two lateral surfaces, so that portions of the first bands and second band overlap one another on each of the two opposite transversal surfaces. The part feeds the stack bound with the bands to sealing parts located opposite at least one of the transversal surfaces of the stack, which seal together the above-mentioned overlapping portions of the two bands by contact with contrast and protection plates which are inserted between the overlapping zones of the bands and the transversal surfaces of the stack in such a way that they operate in conjunction with the sealing means.
