A clamping and conveying device for a material bag filling system is provided. Through displacement of X-axis rails and a Z-axis rail and rotation of rotating arms, grippers can be rotated and inserted into a filling tube portion of a material bag. Cantilevers can be moved away from each other for the filling tube portion to be stretched. Through the rotation and return of the rotating arms, the displacement of the cantilevers and the clamping action of the grippers, the filling tube portion is clamped stably. The cantilevers are displaced to the bottom of the material filling device by the Z-axis rail and the X-axis rails. The filling tube of the material filling device is displaced to enter the material bag for blowing air and filling the material. Through a conveyor belt, the material bag with the filled material is conveyed to a sealing device for sealing.

A system for manufacturing tamper evident packaging, for example a bag with a tamper evident seal, includes a noncontact sealing device, a manufacturing conveyor, and in some implementations, a tensioning device and a closure device. The manufacturing conveyor conveys the bag to opposing pairs of in-feed belts of the non-contact sealing device, wherein the belts hold opposing sides of the bag together and a laser with an outlet positioned between a first pair of the belts spot welds the bag along a specified line to fuse the opposing sides of the bag together proximate an opening of the bag. In implementations including the tensioning device and the closure device, the tensioning device draws the opposing sides of the bag together prior to the bag entering the noncontact sealing device, and the closure device applies a removably coupleable closure to the bag after the bag exits the non-contact sealing device.

An automatic machine includes: a central frame; a support rotatably connected to the central frame; handling mechanisms for moving the support; a plurality of carriages supported by the support; each carriage supports a bag vertically; a loading station; a spreading station downstream of the loading station; a filling station downstream of the spreading station; a first heat-sealing station downstream of the filling station; an insertion unit that loads a straw in the bag; a second heat-sealing station. The insertion unit is provided in the first heat-sealing station.

A bagging assembly for bagging bales of fibrous material is disclosed. The bagging assembly incorporates a chute defining a channel for receiving a bale, which is pushed there between by a stuffing assembly. Aspects of the bagging assembly include raising a bale using a bale elevator to a higher elevation position so that the bale could be stuffed by the stuffing assembly and using a bag retrieving mechanism for retrieving a bag from a bag location for use in bagging the bale.

[Problem] Providing a packaging method used in a bag-feeding and packaging apparatus, which can realize speed-up of the bag-feeding and packaging apparatus without limitation of movement acceleration due to the spilling or scattering of an article during movement and which can realize a larger amount of packaging in a short time, and the bag-feeding and packaging apparatus implementing the packaging method. [Overcoming Means] In the packaging method used in a bag-feeding and packaging apparatus P in accordance with the present invention, packaging processes are performed while a packaging bag F is intermittently moved to packaging stations 1 to 9 together with a mover 32, so that an article is packaged, and the packaging stations 1 to 9 include an article (a fluid) filling station 5 where an article filling process of filling the packaging bag with the article is performed. In the article filling station 5, a bag mouth of the packaging bag F is closed before movement to a subsequent packaging station (a steam deaeration/seal part preheating station) 6 after the article filling process has been performed.

A method for handling containers (I) of collapsible type in a filling machine (20) comprising consecutively arranged stations (S1, S2, S3, S4, S5, S6) comprising a filling station (S3) and a gas filling station (S5), the method comprising intermittently moving the containers (I) to the consecutively arranged stations (S1, S2, S3, S4, S5, S6), supplying, at the filling station (S3), liquid product into the product compartment (5) and supplying, at the gas filling station (S5), gas into the handle compartment (7). The filling station (S3) and the gas filling station (S5) are operated such that liquid product is supplied to the product compartment (5) of one of the containers (I) while gas is supplied to the handle compartment (7) of another of the containers (I). The step of supplying gas at the gas filling station (S5) comprises providing a first gas flow (Qi) at a first pressure (Pi) and delivering said first gas flow (Qi) from the nozzle (30) to the handle compartment (7) via said inlet (11), and subsequently providing a second gas flow (Q.sub.2) at a second pressure (P.sub.2), lower than said first pressure (P.sub.1), and delivering said second gas flow (Q.sub.2) from the nozzle (30) to the handle compartment (7) via said inlet (11) for establishing a target pressure (P.sub.T) inside said handle compartment (7) corresponding to said second pressure (P.sub.2).

The invention relates to a valve bag, in particular a cross-bottom valve bag, comprising a first wall and a second wall, which are joined to each other by means of side edges or side folds and by means of bottoms and which delimit a bag interior, comprising a valve, which is arranged in one of the bottoms and via which the bag interior can be filled with a filling material, and comprising venting openings in the first and/or in the second wall for venting the bag interior. At least one channel is provided on the outside of at least one wall, which channel covers the venting openings and is formed at least by two parallel fastening strips and by a cover strip, the cover strip likewise comprising venting openings, and wherein the shortest path between the parallel fastening strips along the cover strip is longer than the shortest path along the at least one wall or the cover strip, and/or the parallel fastening strips consist of stretchable material.

The packaging machine for packaging products in preformed flexible containers with closing element comprises a feeding station (1), which feeds the preformed flexible containers (10) with closing element; a dosing station, which doses a product into the containers; and a sealing station (6), which seals the container with the product inside, wherein the packaging machine also comprises an opening station (3), in which said container (10) is opened, said opening station (3) being positioned before said dosing station.

It allows the container to be fed with the closing element open or closed, as the opening station allows the closing element to be opened if it is closed, increasing the productivity of the packaging machine.

An adjustable table assembly for use in a filler assembly includes a table having a top surface configured to receive a flexible container thereon and a clamp disposed on the table and configured to releasably secure the flexible container to the table. The table has an infeed end and an outfeed end opposite the infeed end. The table is movable along a plurality of rails affixed to the filler assembly. The table is movable between a loading position, in which the table is configured to receive the flexible container, and an operating position, in which the table is inside the filler assembly. The movement of the table along the plurality of rails is along a first axis. Filler assemblies and methods of using adjustable table assemblies are also disclosed.

A magnetic pouch clamp assembly includes a first and second clamping arms and a magnet assembly. The first clamping arms have respective, opposed first and second clamping surfaces. The second clamp arm is slidably connected to the first clamping arm such that the first and second clamping arms are movable between open and closed positions, with the first and second clamping surfaces being engaged in the closed position. The magnet assembly includes a first magnet having a first polarity carried by the first clamping arm and a second magnet having a second polarity carried by the second clamping arm, the first and second polarities being oriented such that a closing attractive force therebetween holds the first and second clamping surfaces in the closed position. A third magnet can be used to hold the clamping surfaces in the open position or to enhance closing forces.
