The invention relates to an apparatus (1) and method for forming food-grade capsules (C), which are made from an aluminum strip or film, particularly to contain water-soluble powder substances, such as coffee, barley, ginseng-flavored coffee, teas, infusions, cocoa, food preparations, etc. The capsule (C) comprises a central cup-like portion (12) from which a conical or convex upper annulus (13) cantileverly extends on which the dispensing unit of a coffee machine is intended to move into abutment in a watertight manner, the capsule (C) for preparing the soluble beverage being inserted, in use, into the coffee machine. The central cup-like portion (12) and the upper annulus (13) are obtained by deep-drawing the aluminum strip in opposite directions by means of forming elements of the apparatus (1).

The invention relates to an apparatus, machine and method for forming caps made from plant fiber or from a paper material intended to replace common caps made from metal or plastics, such as PET. The apparatus comprises a first mould half and a second mould half. The two mould halves are movable with respect to each other along a longitudinal axis, between a distal position and a proximal position. In the closed position, the first mould half and the second mould half together delimit an impression corresponding to the cap to be formed. A cutting blade to cut the band of plant fiber or of paper material, and a male forming element are provided on the first mould half. A counter cutting blade to cut the band, and a female forming element are provided on the second mould half. The male forming element can be at least partially inserted into the female forming element to deep-draw the cap. To prevent the formed cap from remaining engaged on the male forming element when the apparatus is opened, thus requiring manual unscrewing by an operator, the apparatus is configured with the male forming element rotatable about the longitudinal axis with respect to the first mould half. Thanks to this feature, the fully-formed cap can be unscrewed from the male forming element and consequently ejected from the apparatus automatically without operator intervention.

The invention relates to an apparatus (10) and method for moulding food-grade containers (100) from a strip (C) of paper material. The apparatus comprises a stationary die-holder plate (11), and a die- holder plate (12) which is movable with respect to it between an opened position and a closed position. The stationary die-holder plate comprises a respective stationary die half (14) and the movable die-holder plate comprises a respective mobile die half (15). In the closed position, the two die halves (14, 15) cooperate to define an impression corresponding to a container (100)provided with a bottom (101), a side wall (102), and a substantially flat perimeter portion (103) cantileverly extending from the side wall. A curling member (20), a permanent pleating member (19) and a cutting blade (18) are concentrically provided around the mobile die half and sequentially arranged from the inside to the outside thereof. Similarly, a counter curling member (23), a counter permanent pleating member (22) and a counter cutting blade (21) are concentrically arranged around the stationary die half. The blade and the counter cutting blade interact to cut a blank (C')from the starting strip, the dimensions of the blank being proportional to the dimensions of the container to be moulded. The permanent pleating member and the counter permanent pleating member interact to permanent pleat or wrinkle a peripheral crown (CI) of the blank at least at a portion of the side wall. The curling member and the counter curling member interact to form a curled edge extending externally from the peripheral flat portion of the container being moulded. Advantageously, the mobile die half can be at least partially inserted into the counter curling member so as to form the curled edge (104) of the container between the lying plane of the respective flat perimeter portion and the bottom of the container itself.

The invention concerns the equipment for forming of paper containers starting from a continuous wet paper belt. It comprises a mobile semi-mold and a fixed semi-mold defining an impression corresponding to the container to be produced. Around the mobile semi-mold (15) are provided concentrically an upper cutting blade (18), an upper pleating/crimping ring (19) and an upper rim former (20); around the fixed semi-mold (14) are provided a counter cutting blade (21), an upper counter pleating/crimping ring (22) and a counter rim former (23), associated respectively with the cutting blade, the pleating/crimping ring and rim former on board associated with a mobile semi-mold. And this, respectively, to cut from the initial paper tape a length of paper depending on the measurements of the container to be formed, to pleat/crimp a peripheral crown of said blank paper during the closing stroke of the semi-molds, and to form a crimped rim around the lateral wall of the container during the opening stroke of said semi-molds.

This invention concerns a press and a method in particular for the forming of finished articles, such as containers or trays of paper and starting from a moisturized sheet. The press comprises a bedplate (18) having a fixed die holder plane (19) holding a head (20) with a moving die-holder plane (21) movable with regards to the fixed plane between an opening and a closing position. A lower die (22) is attached to the fixed die holder plane, whereas an upper die (23) is attached to the moving die-holder plane. The moving die-holder plane is powered by an electric actuator (29) for the opening and closing movements and the half-dies are provided with heating means for the drying and hardening of the paper in a set closed position. The moving die-holder plane can be slowed down or stopped during its stroke to allow for the drying of the paper.
