Method for wrapping printed matter by placing film sheet around the printed matter, comprising the steps of:
- placing a film sheet on a first conveyor device;
- placing a printed matter partly on top of the film sheet such that a front part of the film sheet in the conveying direction is not covered by the printed matter;
- conveying the film sheet with the printed matter below a first height adjustable elevated belt;
- blowing upwardly the front part of the film sheet to a vertical position with an upward air current provided at an end of the first height adjustable elevated belt;
- and
- continuously conveying the film sheet and the printed matter below a second height adjustable elevated belt such that the front part of the film sheet is folded along top side of the printed matter.
Apparatus for wrapping printed matter by placing a folded film sheet around the printed matter, comprising:
- a lower conveyor device for conveying a film sheet placed thereon;
- two height adjustable upper conveyor devices arranged in line with each other at a distance and directly above the lower conveyor device;
- and
- one or more upwardly directed air nozzles arranged in a transverse gap between the two upper conveyor devices and below the lower conveyor device.
