Abstract: A method, a cutting device and an apparatus wherein, at cusp-shaped recesses obtained by die cutting on a ribbon in order to obtain pouches with rounded corners, the ribbon is cut transversely by means of at least two strokes of a blade. A relative translation is performed, between the first stroke and the second stroke, between the cutting plane and the ribbon substantially along a feeding direction of the ribbon, so as to level with the second stroke any cutting defects of the first stroke in the region of the recess.

Abstract: A station for feeding closing seals for containers, which includes at least one fixed magazine of seals which is provided with an outlet from which the seals can be taken individually. The station includes a carousel for feeding seals which can rotate with respect to a first central rotation axis and is provided with pickers which are radially spaced apart from the first rotation axis. The pickers are individually rotatable about a second rotation axis which is not parallel to the first axis of the carousel. During the rotation of the carousel, at least one picker can is configured to rotate about the second axis from a position for taking the seal from the magazine to a position for releasing the seal.

Abstract: A method for manufacturing pouches made of at least partly thermoplastic material, including the steps of superimposing at least two webs of at least partly thermoplastic material, joining the webs at adhesion regions or lines, and cutting the webs at cutting regions or lines in order to provide pouches. In a condition in which the webs are superimposed, the method further includes the step of mutually aligning the webs by causing the elongation of at least one of the two webs via the application of heat.

Abstract: An assembly for manufacturing containers by thermoforming, which includes a magazine of thermoplastic sheet-like blanks, a feeding station for feeding the blanks, a heating station for heating the blanks, and a station for thermoforming containers starting from the blanks. The feeding station includes a closed-loop path and at least two conveyor elements, which move, following each other, along the path between a loading position, in which the conveyor element faces the blank magazine, and an unloading position, in which the conveyor element faces the heating station. The heating station includes a heating carousel, wherein, in the active condition, the conveyor element in the unloading position moves with a substantially linear motion with a speed that is substantially equal to a peripheral speed of the heating carousel.

Abstract: A station for sealing thermoformed containers for a packaging line and a method for sealing the containers includes a sealing carousel which rotates continuously about a central axis and includes sealing heads which are radially spaced apart from said central axis. Each sealing head is adapted to receive at least one container to be sealed at a first, input, peripheral region, which is outside the sealing carousel; receive at least one closing seal at a second, input, peripheral region, which is outside the sealing carousel; and hold the closing seal and the container during the rotation of the sealing carousel and couple them together. The station further releases the container complete with the closing seal at a third, output, peripheral region, which is outside the sealing carousel and angularly spaced from the first and from the second region.

Abstract: A mixing-dosage apparatus for rotary machines for packaging containers includes a mixing portion and a dosage portion. The two portions have a selective fluid connection using a flow control valve, which acts between the two portions so as to feed the dosage duct with consecutive loads of mixed food mass. Each load has a volume that is approximately equal to the volume of the mixing chamber.

Abstract: A device for checking pouches adapted to contain a substance such as a liquid, a powder or a purée, includes at least one carousel adapted to convey the pouches, supporting them along its peripheral region, and at least one duct for supplying a test fluid that is connected to at least one nozzle insertable in a respective pouch conveyed by the carousel. The device further includes elements for detecting a variation in the pressure and/or flow rate of the test fluid in the supply duct after the test fluid has been supplied to, or drawn from, the pouch through the duct and the nozzle.

Abstract: A method of supplying pouches intended for containing liquid, viscous, or granular products to a carousel includes the steps of: positioning pouches along a first zone that is part of a first feeding component for feeding the pouches to the carousel; moving the pouches in the first zone as far as the carousel; and picking up the pouches from the first zone via the carousel; The method further includes positioning pouches along a second zone that is part of a second feeding component for feeding the pouches to the carousel. The step of positioning pouches along the second zone occurs in part simultaneously with picking up the pouches from the first zone; moving the pouches located in the second zone as far as the carousel queuing the pouches behind the pouches located in the first zone; and picking up the pouches from the second zone via the carousel.
