Feed Assembly for Supplying Sheet Elements to a Graphic Printing Station

An insertion assembly for the continuous and automated feeding of laminar elements into a graphic printing station, with the laminar elements in a stacking area for laminar elements, arranged in at least one column, comprising:

• an insertion device that includes a rotating belt system on which the laminar elements can be moved horizontally, and suction means, with the insertion device connected to the stacking area, and
• a pulling device that includes a rotating belt system on which the laminar elements from the insertion device can be moved horizontally, and suction means, with the pulling device connected to a graphic printing station equipped with a rotating belt, with said pulling device adjoining the insertion device in a direction of forward motion,
• such that a laminar element is carried from the stacking area to the graphic printing station through the insertion device and the pulling device, with the speed of the rotating belt of the pulling device constant and equal or essentially equal to the speed of movement of a series of movement elements in the printing station, on which the laminar element moves during the operation thereof, the insertion device including a lifting means that lifts the laminar element with respect to the rotating belt, with the movement of the lifting means synchronized with the suction means, and wherein the suction means include valve elements that are integrally connected to the lifting means, such that when the valve means are open, the lifting means is in a bottom position and when the valve means are closed, the lifting means is in a top position.
