ABSTRACT:
The invention relates to a packaging machine for wrapping books or the like for postal deliveries. The package blank includes a rectangularly shaped outer cardboard (2), which is folded by means of transverse belts (5) from a flat condition to a tube surrounding the four sides of a book. The belts (5) extend through sliding slots included in the bottom edge of guides (8) and said guides (8) are operated in vertical and horizontal plane by means of pneumatic cylinders (11, 14). The apparatus also requires two sets of individually operable press plates (6 and 7) for pressing the package from above before and after the folding of a sheet of cardboard (2). (FIG. 2)
