AN APPARATUS FOR CHANGING AN ADVANCEMENT DIRECTION OF PILES OF INSERTS TO BE STUFFED IN ENVELOPES.

摘要

An apparatus is described that is usable in an envelope stuffing machine (100) for changing an initial advancement direction (I) of piles (2) made up of inserts to be put in envelops comprising: at least a thrust device (31 32 33 34) for pushing a pile (2) in a thrust direction (S) arrangeable in such as way that the thrust direction (S) is perpendicular or oblique with respect to the initial advancement direction (I) and at least a connecting device (4) comprising drawing means (41 42) for transporting piles (2) along a transport pathway (P1 P2 P3) at a terminal end of which transport pathway there is an outlet (U) of the connecting device (4) which drawing means (41 42) are suitable for receiving piles which are supplied to the apparatus (1) having said initial advancement direction (I) the drawing means (41 42) being curved in such a way that the transport pathway (P1 P2 P3) comprises at least an arced tract (P2) with a centre of curvature located on a main axis (O) perpendicular to the initial advancement direction (I) whereby upon the crossing of the arced tract (P2) the piles (2) exhibit an intermediate advancement direction (M) which is oblique or transversal with respect to the initial advancement direction (I); the thrust device (31 32 33 34) being located downstream of the connecting device (4) in a position in which it can receive the piles (2) which exit from the connecting device (4).
