The invention is directed to straight, consistent body scores on plastic corrugated boxes and a process for making the body scores.

An automatic packaging machine including a folding assembly of a continuous sheet of packaging material, in particular paper, having a sliding plane for conveying the continuous sheet of packaging material along a conveying direction is disclosed. The sliding plane includes an entrance end for entering the continuous sheet of paper and two opposite sides parallel to the conveying direction. Further, the folding assembly includes a feeding assembly for feeding the continuous sheet of packaging material along a feeding plane which is substantially orthogonal to the conveying direction and defined at the entrance end of the sliding plane. The folding assembly further includes a block associated with at least one of the opposite sides of the sliding plane and a body associated with the block and provided with a cone-sector surface which supports a longitudinal flap during longitudinal creasing and accompanies it during the folding along the longitudinal creasing.

The invention relates to a method for folding a corrugated cardboard blank (1) intended to form a folded box, the method comprising the following series of steps:

i) supplying a blank (1) comprising at least one longitudinal crease (11);
ii) applying a liquid to the longitudinal crease (11) so as to make the corrugated cardboard more flexible at the location of the longitudinal crease (11), the application being performed by means of a liquid application arrangement (130) comprising a liquid-ejection nozzle (134) provided with a liquid outlet;
iii) folding the blank (1) around the longitudinal crease (11);
wherein an aspiration of liquid is produced inside an aspiration compartment (163) of the liquid application arrangement (130) during step ii). The aspiration making it possible to remove any excess liquid which might not have been absorbed by the cardboard and/or the cardboard dust produced.

A method for converting a flat substrate (W) in a station (3) for converting a flat substrate (W) that includes a rotary cutting unit (9) and at least one rotary deformation unit (7, 8) positioned upstream of the rotary cutting unit (9) in the direction of movement (L) of the flat substrate (W), the method including: determining the conversion parameters of the flat substrate (W), such as the deformation layout and cutting layout; choosing a sleeve (13) carrying a form for carrying out the deformation depending on the deformation layout; mounting the sleeve (13) on a mandrel (12) in the rotary deformation unit (7, 8); choosing the cutting tools (91, 92) depending on the cutting layout; mounting the cutting tools (91, 92) in the rotary cutting unit (9); and starting the conversion of the flat substrate (W).

The present invention relates to a box forming machine for forming boxes of different shapes and sizes, comprising a forming station including an operating space, demarcated by upper and lower devices and receiving a box during the forming thereof, without horizontal movement of said box; flexible, pressurizable, and heatable glue conduits connected to a plurality of glue application nozzles, configured for being positioned in different positions consistent with the size of the box to be formed, and at least one electrically-operated valve configured for applying said hot glue in respective relative positions of said glue application nozzles with respect to the box, according to operative parameters associated with the dimensions of the box to be formed, including dimensions of upper and lower flaps of said box and at least one working temperature of a hot glue to be applied previously input in a user interface connected to a control device.

A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blank to form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.

A method of at least partially erecting a carton with a carton forming system includes loading a blank in a blank infeed assembly, the blank having a plurality of panels and a plurality of end flaps foldably connected to a respective panel of the plurality of panels. The method further includes positioning the blank on at least one conveyor assembly, operating the at least one conveyor assembly to move the blank in a downstream direction of the system toward a carton erection assembly, the carton erection assembly including an end flap engagement assembly positioned adjacent the at least one conveyor assembly, and rotating the end flap engagement assembly such that a portion of the end flap engagement assembly contacts and moves at least one end flap of the plurality of end flaps of the blank as the blank moves in the downstream direction.

The invention relates to a packaging apparatus (1) for combining a plurality of articles (8) an outer package (6) formed from a cardboard blank (3). The packaging apparatus (1) comprises a magazine (2) for cardboard blanks (3), the cardboard blanks (3) being stacked and lying on top of one another within the magazine (2), a removal apparatus (4) for the cardboard blanks (3), and a handling device (5). The removal apparatus (4) is vertically and horizontally movable and comprises at least one suction tool (9) for withdrawing a cardboard blank (3) from the magazine (2). The suction tool (9) arranged pivotally movable within the removal apparatus (4) or on the removal apparatus (4) for executing a compensation movement and aligning the withdrawn cardboard blank (3) in a horizontal plane. The invention also concerns the removal apparatus (4) (3) and a method for withdrawing cardboard blanks (3).

A case erector may operate in multiple modes. In a slotted-case mode, the case erector may accept and erect slotted cases, while various plunger-case erection components are deactivated. In a plunger-case mode, the case erector may accept and erect plunger cases, while various slotted-case erection components are deactivated.

The invention is directed to straight, consistent body scores on plastic corrugated boxes and a process for making the body scores.
