Abstract: A machine for filling bags with loose products extends along a longitudinal direction of advancing movement of the bags. The machine includes a station for feeding a bag to a pick-up position, and a plurality of filling stations for filling a respective bag, arranged in succession along the longitudinal direction, downstream of the pick-up position. The bags are picked up and transported from one station to another station. The pick-up position and filling stations are arranged at a predefined and equal distance from each other, corresponding to a step between adjacent stations in the longitudinal direction. The bags are transported by performing single translation movements in the longitudinal direction.

Abstract: Machine for filling bags with loose products, in particular to a forming and filling machine, in which the bags fed one at a time to the single pick-up position are formed along the line from a tubular material, preferably by means of a forming station provided with means for sealing the bottom of each bag, arranged in said pick-up position.

Abstract: An apparatus is for filling bags having a bag mouth extending in a direction of width with loose material. The apparatus includes grippers, suction cups, valves, and a pair of first carriages. 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: Blade for opening bags (1;2) with pleats (1a,2a), comprising a flat body (10) with a bottom edge (11) and a top part (12) suitable for stable engagement with associated operating means, and a tooth (20) substantially extending in the vertical direction (Z-Z) and connected to the body (10) along the top edge (10c) of each lateral side (10b) of the body (10), a cavity (22) which extends in the vertical direction (Z-Z) and is of suitable width in the longitudinal direction (X-X) being formed between each tooth (20) and the corresponding side (10b).

Abstract: An apparatus including a feeding device configured feed a profile in a longitudinal direction, a cutting device configured to cut the profile to form a cut profile section, a gripping device configured to grip and transport the cut profile section, the gripping device being displaceable between a gripping position and a position for introducing the cut profile section into a bag, the gripping device comprising, a pair of grippers to hold the cut profile section, an actuator to move the gripping device in the vertical direction from a position above the bag to a lower position for introducing the cut profile section inside the bag, a moveable guide configured to guide the cut profile section inside the bag, the moveable guide being moveable in the vertical direction between a position above the bag and a position for insertion inside the bag.

Abstract: Transportation apparatus for machines for filling bags (1) with bulk material (2), comprising at least one station (F) for forming the bag (1), at least one station (R) for filling the bag with the material (2), provided with fixed bag gripping means (112,112a), at least one station (S) for sealing the mouth (1a) of the bag and at least one apparatus for transporting the bags from one station to the other station (F,R,S) in a feeding direction (X-X), said apparatus comprising two pairs of the arms (510,1510) which are symmetrically arranged with respect to the direction (X-X) of feeding of the bag and each carry respective pairs of means (514) for gripping the sides (1c) of the bag (1), said pairs of arms (510,1510) being formed by levers (511,1511) which are kinematically connected together in a pantograph arrangement, said first pair of levers (511) being able to travel along a curved trajectory (T) from a point (T1) where the gripping means (514) are situated at a maximum relative distance to a point (T2)

Abstract: Apparatus for filling bags (1) with loose material (2), comprising a tube (210) for supplying the material (2), substantially coaxial with the said bag, said tube (210) being able to move from a position with the supply mouth (210a) outside the bag to a position with the supply mouth (210a) inside the bag (1) and arranged at a height substantially coinciding with the bottom (1b) of the bag (1) where filling is started, and vice versa.

Abstract: An apparatus for forming and applying a sealing flap to seal the mouth of a filled sack, starting from a continuous strip (9) of heat-sealable material includes a first loop conveyor to unwind the strip from the feeder roll and transfer it, using clamp means (10, 11, 12, 13) and guide means (14), to a second loop conveyor (15), likewise provided with clamp means (21, 22, 23, 24) to hold the strip (9). Between the first and the second conveyor (1, 15) cutting means (28, 29) are provided to cut the strip (9) when the section of the latter transferred to the second conveyor (15) has reached a pre-set length corresponding to the width of the sack (31) to be sealed. The second conveyor is associated with a shaping device (26) which, during advance of the strip (9), folds the strip itself until it is substantially in the shape of an upside down U, thus forming the sealing flap (32).

Abstract: A machine is described comprising an arrangement of means for making-to-measure single sacks starting from a continuous tubular tape of heat-sealable plastic material, with simultaneous welding of the respective ends, for filling each of said sacks with the product in question, and for sealing the upper opening of each sack so filled, said arrangement being such as to allow translation of said sacks along a horizontal straight route, and said translation being arranged in such a way that in travelling said route a single time a first of said sacks, being empty, is taken to be filled and a second of said sacks, being full, is taken to have its mouth sealed.
