A method to form cardboard boxes by gluing into a box-forming machine from sheets, said machine, a computer program with instructions for said machine to execute said method, and a computer-readable device that has stored said computer program. In this method, a stage of the movement of inserting a pintle into a mold starts with a controlling element when the position of a drag element of sheet to a delivery position, where you place a sheet aligned between said pintle and mold, it corresponds to a second intermediate position between a source position and said delivery position; and a stage of activation of a supplying actuator starts with a controlling element to supply a sheet subsequent to the source position, when the position of said drag element corresponds to a third intermediate position between said source position and said second position.

An apparatus for forming a container from a blank is provided. The apparatus includes a blank feeder assembly, and a compression assembly including a mandrel assembly, an upper folding arm assembly including a plurality of folding arms moveable between a first position and a second position, a compression plate, and a rollover arm assembly.

Described are a machine and a method for forming containers from blanks, including a plurality of shaping hoppers, an endless conveyor which defines a feed path and on which the hoppers are mounted in succession and a plurality of pushing elements which are movable in such a way as to follow the respective shaping hoppers along at least a stretch of the feed path and which have a to-and-fro operating movement towards and away from the respective hopper along a direction transverse, preferably perpendicular, to the feed path. The machine also includes folding means disposed along the feed path downstream of the pushing elements and configured to produce, respectively, a top closure and/or a bottom closure of the tubular blank.

A deep-drawn paper tray made of paper material, a method and an apparatus for manufacturing the tray, and a closed product package comprising the tray. The tray having a bottom and upwardly expanding side walls around the bottom, the side walls of the tray being shaped to expand through a plurality of circumferential steps dimensioned low enough for obtaining wrinkle-free side walls for the tray. The outermost step is a flat, wrinkle-free rim flange, which enables liquid and gas proof heat-sealing of a lid to form the package. The apparatus may comprise upper and lower moulding tools with concentric movable frames for forming the tray bottom and side wall steps from paper blanks, and moulding tools may be mounted onto a rotating turret carrying a paper blank through working stations arranged along the turret circumference, to shape the tray bottom and the side wall steps at the consecutive stations.

A customizable case former and it 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 machine for forming a container from a blank of sheet material is provided. The blank includes a reinforcing panel assembly for forming a reinforcing corner assembly. The machine includes a hopper station for storing the blank in a substantially flat configuration and a forming station for forming the blank into the container. The forming station includes an initial forming station that rotates a first portion of the reinforcing panel assembly with respect to a second portion of the reinforcing panel assembly, and a secondary forming station having male and female forming members with shapes corresponding to an interior shape and an exterior shape of the reinforcing corner assembly, respectively. The male and the female forming members are configured to form the reinforcing corner assembly by compressing together the first and second portions of the reinforcing panel assembly.
