The grippers are for gripping opposite edges of a bag, which are arranged opposite each other relative to a vertical axis of symmetry and are movable symmetrically towards and/or away from each other with respect to said vertical axis of symmetry in a direction parallel to the direction of width of the bag. The suction cups are for gripping side portions of the bag. The suction cups are movable symmetrically towards and/or away from each other along a direction perpendicular to the direction of width of the bag for opening and/or gripping the bag mouth of the bag. The valves can rotate from a closing position outside the bag into an opening position inside the bag mouth.

Abstract

A method for filling bags with metered quantities of bulk products includes providing a first container and a second container having an assigned total volume. Each container is divided into two respective half-volumes, each half-volume being designed to feed product to a first station or a second station for filling bags, so that each container has a half-volume connected to the first station and a half-volume connected to the second station of the two stations. A first predefined metered quantity of product is provided inside the first container by dividing-up the metered quantity of product into two quantities equal to approximately half the metered quantity, each fed to a respective half-volume of the first container. A bag is conveyed to the first filling station. The bag is filled with the quantity of product of the first half volume of the first container.

Abstract

Apparatus for applying closing means (1, 1a, 1b) to the mouth (5a; 105a) of bags (5; 105) in machines for automatic filling and sealing of said bags (5,105), said closing means comprising a profile section (1) formed by a flat part (1b) and by a shaped male/female head (1a), which apparatus comprises a device (10) for driving the profile (1) in a longitudinal direction (X-X); a device (15) for cutting to size the profile (1) in the transverse direction (Y-Y), arranged downstream of the drive device (10); a device (20) for gripping/transporting the profile section (1), arranged downstream of the cutting means (15) and able to be displaced in both senses of the longitudinal direction (X-X) from a gripping station (S1) to a station (S2) for inserting the closing/opening means into the mouth (5a; 105a) of the bag (5; 105), said gripping means (20) comprising movement means (24) able to move in both senses of the vertical direction (Z-Z) and able to perform correct positioning of the closing/opening means inside the mouth of the bag.
