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).

A method for wrapping an object comprising:
- supporting a cardboard piece having opposite sides on a conveyor having a wrapping station, at least one pair of elongated belts extending transverse to the conveyor, one belt on either side of the conveyor, and a pair of guides, one guide on each side of the conveyor, each guide movably supporting one of the belts;
- engaging a press element with an object on the cardboard piece to hold the object and cardboard piece against the conveyor;
- folding the cardboard piece at the wrapping station by moving the guides upwardly, then toward one another, then alternately downwardly such that the belts fold sections of the cardboard piece first upwardly then alternately on top of one another in overlapping fashion;
- and
- disengaging the press element from the object during said folding.
A method for wrapping an object with cardboard or the like comprising:
- supporting an object on a cardboard piece on a conveyor, the cardboard piece having sections extending beyond opposite sides of the object;
- engaging a press element with the top of the object to hold the object and cardboard piece against the conveyor;
- folding the extending, opposite sections of the cardboard piece over and against the object by moving a pair of belts upwardly to engage the extending, opposite sections, then toward one another, then alternately downwardly such that the cardboard sections are folded alternately in overlapped fashion on top of one another against the top of the object, said belts being located under the cardboard piece with at least one belt on each side of the conveyor, each belt extending transverse to the direction of the conveyor.
