1. A method for covering boxes with at least one flexible sheet blank by means of adhesive joining in a box laminating machine, wherein;
the boxes to be covered have at least one plane bottom and multiple plane walls with at least one outer joining surface, with said walls being connected to the at least one bottom and arranged orthogonal thereto,
the at least one sheet blank formed by at least one material sheet and has at least one joining surface,
the at least one outer joining surface of the at least one bottom or at least one wall of the box is adhesively joined with the at least one joining surface of the at least one sheet blank to form a box unit,
the box laminating machine comprises multiple processing stations and the box to be covered successively passes through these multiple processing stations, wherein
at least one of the processing stations comprises at least one rubbing-down device,
the at least one rubbing-down device has at least one rubbing-down element and at least one counter-holder corresponding to the at least one rubbing-down element,
the method comprising:
transporting the box to be covered between the processing stations in a plane that extends parallel to the at least one bottom of the box to be covered;
plunging the at least one counter-holder of the rubbing-down device into the box and into contact with an inner surface of a wall to be covered,
moving the at least one rubbing-down element of the rubbing-down device over an outer side of the wall to be covered in a rubbing-down movement, wherein
beginning the rubbing-down movement of the at least one rubbing-down element of the at least one rubbing-down device adjacent to or at an edge of the already joined surfaces of the box unit and sweeping the rubbing-down element over a surface of the box unit to be covered during the rubbing-down movement,
the rubbing-down movement of the at least one rubbing-down element of the at least one rubbing-down device takes place while the at least one counter-holder of the at least one rubbing-down device, which corresponds to this at least one rubbing-down element, is in contact with the inner surface of the wall to be covered,
wherein a rubbing-down operation, to include the rubbing-down movement, of the at least one joining surface by means of the at least one rubbing-down device takes place during a continuing transport movement of the box to be covered, with said transport movement running parallel to the at least one bottom of the box to be covered, and
wherein a movement of the at least one counter-holder of the at least one rubbing-down device is at least composed of a first partial movement and a second partial movement, wherein the first partial movement runs parallel to a surface normal of the bottom of the box and the second partial movement runs orthogonal to the first partial movement and parallel to the transport direction of the box during the rubbing-down operation.
