ABSTRACT:
A sheet feeding apparatus (10) and method are disclosed that are fast, efficient, easy to set up and involve a minimum number of components. The sheet feeding mechanism (10) includes a first gripping member (20) comprised of two first suction cups (21) and a second gripping member (40) comprised of two second suction cups (41). The first suction cups (21) are moved along a first path (P1) between a first position and a second position by a first guide means (25). The second suction cups (41) are moved along a second path (P2) between a third position and a fourth position by a second guide means (60). Vacuum means (22,42) are connected to the suction cups (21,41) for picking up, holding and releasing sheets (TS). The first suction cups (21) pick up a sheet (TS) and transfer it to the second suction cups (41) which take the sheet (TS) to a lamination unit (LU1,LU2).
