Abstract: Device for closing bags for containing powder or granular materials, suitable for installation within a belt, roller or similar line for conveying bags, including at least one sealing head (52) and a conveyor member (27) for feeding the bags (60) to the sealing head (52), characterised in that the sealing head (52) presents drive elements (51, 53, 54, 55) causing it to advance, during the sealing process, at the same speed as the conveyor member to enable it to seal a bag (60) while the conveyor member is moving.

Abstract: This system for mutually automatically arranging, according to any desired patterns, bags, boxes or other articles, particularly for use in machines for loading movable platforms (pallets) is characterized by a locating conveyor belt mounted on a carriage so as to also transversely slide, in a preset way, on supporting guides to drive the articles conveyed thereby with a possible motion deriving from the combination of two simultaneous perpendicular motions in order to locate each article, which may be preoriented, in a suitable position to make, in cooperation with other articles, the preset platform filling pattern so as to provide a comparatively compact layered assembly.

Abstract: The invention discloses a novel type of bag threading device to be used in an automatic bag loading apparatus for rotary bagging machines, and substantially comprises a stationary vertical support frame (10) holding a swinging arm (12) bearing at the other end the pincers (13) associated with a system of connecting rod (14) and crank (19) having the function of rotating the pincers (13) in order to position them in the picking phase axially aligned with the bag (3) to be picked and subsequently with the nozzle (2) of the bagging machine, said arm being able to carry out an angular displacement between to bag positioning device (6) and the nozzle (2) of the rotary bagging machine (1) to be fed in that moment, effected by a cam (15) in order to carry out its angular displacement, acting on a roller (17) arranged on said swinging arm (12), the cam (15) being rotated around its shaft by a motor with reduction unit, the cam shaft and that of the bagging machine being rotated in a synchronous way through known mean

Abstract: The invention relates to a system for feeding single bags to automatic bag inserting apparatuses, picking them up and also unsticking the bag being picked up from the underlying ones, in case they are glued to one another because of glue drops during the bag manufacture. The system substantially comprises (see FIG. 3) three units: a first unit provided with suction cups, picking up the bag at its transversal middle portion, where accidental adhesion of bags cannot happen, and lifting it to allow that two unsticking units, including bars being inserted under the bag and unsticking it from the underlying one with a spreading action, are inserted between said bag being picked up and the underlying one. One of the two units is also provided with pincers blocking the bag edges on the open unsticking arms and, in the return stroke of the unit to the starting position, transferring it on to the feeding device of the bag inserting apparatus.
