The present invention provides a method to form cardboard boxes (B) by gluing into a box-forming machine (100) from sheets (S), said machine (100), a computer program with instructions for said machine (100) to execute said method, and a computer-readable device that has stored said computer program. In this method, a stage (f) of the movement of inserting a pintle (20) into a mold (30) starts with a controlling element (70) when the position (P) of a drag element (11) of sheet (S) to a delivery position, where you place a sheet (S) aligned between said pintle (20) and mold (30), it corresponds to a second intermediate position (P2) between a source position and said delivery position; and a stage (b) of activation of a supplying actuator (61) starts with a controlling element (70) to supply a sheet (S) subsequent to the source position, when the position (P) of said drag element (11) corresponds to a third intermediate position (P3) between said source position and said second position (P2).

A machine a mandrel assembly includes a mandrel having an external shape complimentary to an internal shape of at least a portion of a container, a first lift mechanism operatively coupled to a first servomechanism to wrap a first portion of a blank about the mandrel, a second lift mechanism operatively coupled to a second servomechanism to wrap a second portion of the blank about the mandrel, and a folding arm coupled to the first lift mechanism and operatively coupled to a third servomechanism. A control system is in communication with the first servomechanism, the second servomechanism, and the third servomechanism and is configured to transmit a signal to each of the servomechanisms to independently control movement of the first lift mechanism, the second lift mechanism, and the folding arm to wrap at least the first and second portions of the blank about the mandrel to form the container.

A paper box package forming apparatus includes a continuous feeding device, a box folding mechanism and a cover sealing mechanism. The continuous feeding device includes a paperboard stacking frame, an adsorption mechanism and a roll extrusion conveying mechanism. A paperboard is absorbed from a back side of the paperboard stacking frame through the adsorption mechanism and conveyed to a box folding device through the roll extrusion conveying mechanism. The box folding device includes a downward-pressing inner punch, a box folding outer mold and a pushing mechanism. The pushing mechanism conveys a bottom box to the cover sealing mechanism. The downward-pressing and attaching mechanism includes downward-pressing driving mechanism, a top-pressing plate, side-pressing plates and overturning cylinders. The side-pressing plates are hinged to side edges of the top-pressing plate through the driving of the overturning cylinders.

A modular case system and method of use provide for a case former having a base, interchangeable case gages and forming heads. Contained within the interior of the base are slide blocks mounted on slide rails and assemblies in such a manner as to allow the slide blocks to be slidingly reconfigured to form a case forming cavity of varicose sizes and shapes. The size and shape of the case forming cavity is established and maintained by a template opening, defined by, and potentially unique to, each case gage. The size and shape of the forming head corresponds to the size and shape of the template opening. The slide blocks are secured to the case gage by removable locking pins.

A method for producing a shaped sheet of wrapping, including a hollow portion and a perimetral edge that extends along a pre-set profile, is provided. The method includes laying a sheet of wrapping on a treatment surface having a forming cavity. The method includes forming the sheet of wrapping within the forming cavity so as to reproduce the shape of the hollow portion thereon, without subjecting the sheet of wrapping to deformation by stretching. The method includes cutting the formed sheet of wrapping along the pre-set profile for producing the perimetral edge and obtaining the shaped sheet of wrapping. In the method, the cutting step envisages the use of a laser beam according to a particular cutting mode.

Provided a device and method for paperboard stamping forming, relates to the technical field of paper material stamping forming equipment, comprising a punch-pin and a pressure-applying component, the pressure-applying component acting on a paperboard through a fluid medium; before the punch-pin carries out a stamping forming on the paperboard, the pressure-applying component pre-deforms the paperboard and a direction of the pre-deformation is opposite to a direction of the stamping forming; aiming to the current problem that the forming depth that is difficult to meet requirements resulted in the paperboard forming paper container limited by the deformation capacity of the paperboard, the forming depth of the paper container is improved by making the paperboard deform twice in opposite directions, bringing into play the deformation capacity of the full area of the paperboard, increasing the deformable amount of the paperboard, and reducing problems such as cracks and breakage in the forming process.

A paper-based composite container for an off-gassing product includes a paperboard can body having a substantially gas-impervious liner attached to an inner surface thereof, and a pair of substantially paper-based end closures attached to the opposite ends of the can body, each end closure defining a generally cylindrical sealing panel in contact with an inner surface of the can body. Heat-sealable materials are disposed on opposing surfaces of the sealing panel and can body. The sealing panels of the end closures are attached to the can body by heat seals. The heat seal for at least one of the end closures is discontinuous such that at least one vent channel extends through the heat seal to establish fluid communication between an interior of the container and the environment outside the container. The at least one vent channel is operable to vent excess gas pressure from the interior of the container.
