Abstract: Containers (2) for food products are manufactured employing a system that includes a feed station (4) supplying a succession of tubular elements (2a), and a heat sealer (10) positioned to close and secure a first open end (2b) of each tubular element (2a) that coincides with the base of the container. The sealing operation occurs at a station associated with a conveyor (3) consisting in a wheel (11) rotatable in a feed direction (B) along a path (P) passing both through the feed station (4) and through the station occupied by the heat sealer (10). The tubular elements (2a) are carried by radial elements (13) of the wheel (11) such as can be indexed between a first operating position, where the tubular elements (2a) are taken up from the feed station (4), and a second operating position in which the open end (2b) is offered to the heat sealer (10).

Abstract: A system (1) for manufacturing containers (5) is designed around a supporting structure (2) with which all the stations (7, 18, 19, 21, 24, 25) and the devices (14, 15, 16, 17, 20, 22, 26) needed to produce the containers are associated. The system (1) is equipped with a feed station (7) supplying a forming material (9), a scoring station (18) by which crease lines (4a) are generated, and a cutting station (19), combining to prepare a succession of blanks (4). The system (1) also includes a prefolding station (21) where each blank (4) is bent initially along the creases lines (4a), a folding station (24) where the single blank (4) is fashioned to the shape of the container (5), and a sealing or welding station (26) at which the shape of the container (5) is fixed definitively.

The circular top plate also has, on its peripheral edge, a number of seats, each for receiving a container to be conveyed resting on the bottom platform. The conveyor also has fastening means for fastening the circular top plate to the supporting shaft. The fastening means include at least one clamp movable between an idle position permitting engagement of the top attachment end by the circular top plate or removal of the circular top plate from the top attachment end of the supporting shaft, and a work position to grip the circular top plate between the radial projection and the clamp. And an actuating member moves the clamp between the work position and the idle position.

Abstract: Groups of products stacked on edge are wrapped in sealed stick packs by a method that involves passing a sheet (4) of heat-sealable wrapping material around each group (1) of products (2) and sealing the two side edges (8) in such a way as to fashion a tubular wrapper (12) with end portions (14) projecting axially from the assembled group (1), then spreading each end portion (14) flat by inserting a tongue (16) and heat-sealing each relative pair of flattened edges to render the wrapper airtight. Thereafter, the sealed ends are subjected to a cold crimping action from which each end portion (14) emerges with two impressed crease lines (24) positioned to delimit a central portion (25) that will be folded directly against the corresponding end face of the group (1), and two lateral portions (26) that will be folded inwards over the central portion (25).

Abstract: Containers (2) having a threaded neck (3) and a mouth (4) are capped by a unit (1) appearing as a carousel (5) equipped with capping heads caused to advance along a circular path (P) and capable of axial movement toward and away from the containers in such a way that each one can be fitted with a relative cap (11); each capping head of the unit (1) incorporates a gripper (31) furnished with two jaws (30) presenting relative conical surfaces (26), and respective cylindrical surfaces (27) designed to locate against the neck (3) of the container. When the cylindrical surfaces (27) register against the outer surface of the neck (3), the conical surfaces (32) are positioned with the lower edges (28) encroaching on the area compassed by the mouth (4) in such a way that the cap (11) can be gathered and aligned with the neck (3) of the container (2) before being tightened, thereby ensuring a precise fit.

Abstract: Containers are transferred from a first conveyor operating at a first height to a second conveyor operating at a second height by a rotary unit equipped with a plurality of grippers designed to take up and support each successive container by the neck. The grippers are carried by respective slides mounted to corresponding vertical guide elements making up the main frame of the unit, on which they are made to move up and down cyclically by a first roller following a first track that extends around a fixed C-shaped tubular element, and by a second roller running on a second track presented by the top surface of a sector rail placed with the concave side directed toward the lateral opening in the C-shaped tubular element. The tubular element is easily replaced in the event of a size changeover.
