摘要:
Methods and apparatus for changing a strip of sealed bag precursors in to open bags are disclosed. The apparatus is referred to as a transforming or bag opening machine and includes a separation station and may include a perforation station and a piercing station. The perforation station forms a plurality of end perforations in the multiple layers of a strip of sealed bag precursors. The separation station separates the plurality of end perforations in at least one film layer of the trip to form a plurality of bag openings. The plurality of end perforation are torn by the separation station, which includes manipulating the rotation of a main roller, a pressure roller and at least one separation roller.

A working device (1) to be used on blanks running essentially in a planar manner within a folding and gluing machine, with the outer printable surface originally oriented downwards. First turning device (10) turns over each blank so as to position its outer surface on the top. A transport device (20) moves each blank with the outer surface on the top. An action device (30) implements at least one of printing the outer surface of each blank on the one hand and monitoring the outer surface of each blank on the other hand, while the outer surface is facing up. A second turning device (40) turns over each blank again in order to reposition its outer surface downward.

A method for producing bags containing fiber material, comprises the steps of forming at least one continuous layer of fiber material; separating in succession portions of fiber material from the continuous layer and moving them along a predetermined path; feeding each portion of fiber material to respective containment and compaction elements of a first transfer conveyor; feeding an ordered succession of bags containing respective portions of fiber material to respective supporting elements of a second transfer conveyor; transferring the portions of fiber material from the first transfer conveyor into respective housings of a third transfer conveyor; transferring the portions from the third transfer conveyor inside containment bags carried by a second transfer conveyor; transferring the containment bags from the second transfer conveyor to a fourth transfer conveyor; and moving in succession the bags housing respective portions of fiber material to a folding unit at which the bags are closed.
