A forming machine for erecting a packaging article, the machine comprising a female cavity and a plunger which moves up and down in a generally vertical cycle and which can push a packaging article down into the cavity when moving down, in which the plunger is driven to move up and is not driven to move down.

A box forming machine includes a converter assembly, a fold assembly, and an attachment assembly. The converter assembly converts sheet material into a box template. The fold assembly engages a first end of the box template and moves the first end of the box template to a predetermined position. The attachment assembly engages a second end of the box template and moves the second end of the box template toward and into engagement with the first end of the box template to attach the first and second ends of the box template together.

The invention relates to a blank of corrugated cardboard sheet material consisting of a first body (10) and a second body (11) of rectangular shape which are connected together by means of a line to be cut and designed for forming a set of a first belt and a second belt intended to form a box having a length L, a width W and a height H, the first and the second bodies having different widths and lengths and the line extending along the length of the first and second bodies, the first body (10) having a width (D1) larger than the length L and a length (D2) larger than at least twice the width W plus the height H (2W+H) and the second body (11) having a width (d1) larger than the width W or the height H and a length (d2) larger than the length L plus twice the height H or twice the width W.

Disclosed is a corrugated paperboard box making machine 1 in which a slotter device 6 comprises: a first slotter unit 61 comprising a first slotter 610, a first stationary blade 612 and a first displaceable blade 613; and a second slotter unit 62 comprising a second slotter 620, a second stationary blade 622 and a second displaceable blade 623. A control device 100 is operable to switch the slotter device 6 between a first production mode and a second production mode. Specifically, the control device 100 is operable, when implementing the second production mode, to acquire and store a total blade length of the first stationary blade 612 and the first displaceable blade 613 and a total blade length of the second stationary blade 622 and the second displaceable blade 623, and perform positioning control for the slotter blades, based on the stored total blade lengths.

A method and apparatus for producing trays that are or are not coated with a plastic film and that retain modified atmospheres and the trays obtained. The apparatus allows for obtaining trays with different structures, which include the forming of the trays from previously elaborated preforms, which may or may not have a separator inside the trays and optionally coated with a plastic film inside. It also consists of the method for obtaining the trays and the trays obtained. The trays coated with a plastic film have the capacity to contain atmospheres with a composition of gases different from that of the air inside them, to extend the time of storage and conservation of food products. This is achieved by means of a closed top seal of the tray. The trays also have a simple closure or capping, without modifying their atmosphere.

A converting assembly performs a plurality of conversion functions on sheet material to convert the sheet material into packaging templates. The converting assembly includes a plurality of tool rollers. Each of the tool rollers has one or more conversion tools thereon. The one or more conversion tools on an individual tool roller are configured to perform a subset of the plurality of conversion functions that convert the sheet material into packaging templates.

The invention relates to an apparatus (10) for feeding a plurality of flat elements (12) lying flat on one another, in particular carton blanks, to a packaging apparatus (V), comprising: a first feed section (18) having a conveying device (46), of which the conveying surface (22a1) intended to support the flat elements (12) is formed from a material which, with respect to the interaction with the flat elements (12), has a predetermined coefficient of adhesive friction, and a second feed section (20), which falls toward the packaging apparatus (V), wherein the inclination of the first feed section (18) and the inclination of the second feed section (20) toward the packaging apparatus (V) are different from each other.

A sheet folding device and a box-making machine, wherein are provided folding guides disposed along a transfer direction on both sides in the transfer direction of a cardboard sheet, guide plates disposed downstream from the folding guides along the transfer direction on both sides in the transfer direction of the cardboard sheet, gauge roller groups disposed along the transfer direction further outside in the width direction of the cardboard sheet than the folding guides and the guide plates, folding guide adjustment devices for adjusting the width-direction position of the cardboard sheet in the folding guides, and a second gauge roller adjustment device for adjusting the width-direction position of at least gauge rollers disposed facing the second folding guide from among the gauge roller groups.

The present invention relates to material packaging made of corrugated cardboard sheet having a polygonal cross section, comprising lateral walls, a lower plane forming the bottom of the packaging, and an opposite upper plane. It comprises at least one portion (25, 26) projecting with respect to the upper plane. The bottom (30) comprises at least one surface portion (15, 16) that is cut out over a portion of the thickness of the cardboard sheet, is compressed and in the form of a non-through hollow, referred to as a hollow portion, the shape of which matches the projecting portion, in line with the latter and arranged to fit together with the projecting portion of the packaging below.
