A thermoforming device is described. It relates to a mold assembly including a first and second mold, and to a mold that can be used in a thermoforming device. It also relates to a method for thermoforming a product. The thermoforming device is characterized in that the thermoforming device comprises a second pre-stretcher, in addition to a first pre-stretcher and a calibration element (19, 20), and that the second pre-stretcher is at least partially and moveably arranged in a second mold body (12, 43). A movement relative to the second mold body (12, 43) and towards the same forming cavity of the first pre-stretcher, the second pre-stretcher, and the calibration element (19, 20), can be individually controlled, arid the second pre-stretcher at least partially surrounds the first pre-stretcher and the calibration element (19, 20).

A method for producing an element of a capsule, the capsule being intended to contain a product having at least one component that can be extracted by means of an extraction fluid, comprises the step of obtaining at least one preparatory zone intended to define, during use of the capsule, a passage for the extraction fluid, so that the extraction fluid can pass through the capsule in order to extract said component. The preparatory zone is obtained by means of a cutting operation carried out before the capsule is filled with the product and after the capsule element has been formed. The cutting operation is carried out by means of a blade element.

Method of forming, in particular a thermoforming method, a foil into a container, in particular a brewing container, especially a coffee capsule, using a plug assist and/or pressure difference in axial main forming direction, directing the foil into a forming tool creating a blank with a cavity and pressing the foil towards the forming tool bottom in order to create a floor for the blank and characterising the method in that the floor of the blank experiences a material distribution, especially a material shifting and/or material compression, during which a constant pressure difference within the blank's cavity is guaranteed and a circumferential annular gap is created.

A hollow container producing device for producing a hollow container using a pair of parison sheets is provided. The hollow container producing device includes a pair of molds; an intermediate frame to be clamped to the pair of molds; and a transport unit that carries the intermediate frame and a pair of parison sheets to a position between the pair of molds, with the pair of parison sheets being respectively held on opposite sides of the intermediate frame.

An apparatus for making a capsule provided with a shell containing a filtering element suitable for receiving a product for preparing a beverage or the like includes a superimposing assembly for applying a film of filtering material to at least one shell with a cavity in order to cover an opening of the cavity. The shell is moved along a first advancement direction and the apparatus further includes a locking assembly to lock the film to the shell, and a first stretching device included in a first stretching station for heating and stretching a portion of the film facing the cavity in order to obtain a filtering element.

A method of forming a blow molded container in the form of a tub, the method comprising the steps of: providing an injection molded preform composed of a biaxially-orientable thermoplastic material, the preform being substantially planar; heating the preform; and stretch blow molding the heated preform within a mold cavity to form a tub having a bottom wall and an annular sidewall having an upper edge, the tub comprising biaxially oriented thermoplastic material in the annular sidewall and at least an outer portion of the bottom wall, the stretch blow molding step using at least one stretch rod to engage an inner side of the preform and axially to stretch at least a part of the preform prior to blowing a pressurized gas against the inner side which urges the opposite side of the preform radially outwardly against the mold.
