A bag loading nozzle to confine a flow of material from upstream feed for downstream discharge into a bag having a spouted entrance. The nozzle comprising an interior wall presenting an inlet and an outlet, located intermediate of the inlet and outlet end and about the interior wall is a shape retaining tube and through which the material is to pass from the feed into the bag. At least one actuable fluid inflatable collar at least substantially about the shape retaining tube is provided such that when actuated to its inflated form(s) it will effect at least a substantial sealing with a fitted suitable bag from within its spouted entrance.

What is presented is an interface between a hopper and a dust receptacle of a dust collector system, wherein the hopper has an outlet through which collected dust drops. A slide gate is mounted to the outlet of the hopper and a spout is mounted to the slide gate. A lid is configured to secure to the top of the dust receptacle. The lid has a coupling configured to secure to the spout. A slot comprising a locking feature is located on either the spout or the coupling. A rod corresponding to the slot is mounted to the other of the spout or the coupling than which the slot is located. The lid may be removed from the dust receptacle by lifting the lid to move the rod through the slot and the lid is secured by twisting the coupling relative to the spout to move the rod into the locking feature.

A bag for the storage and transport of a pulverulent product, such as agri-food, mineral, chemical or pharmaceutical powders and like powdery materials, the bag including a bottom part, a sidewall, and an upper part joined together to form a storage volume, wherein the upper part is provided with a filler inlet configured to allow the pulverulent product to be introduced inside the storage volume during a filling operation. The bag further includes lifting straps, and at least one integral elongated section made of an air-permeable material extending inside the storage volume and including an outlet accessible from the outside of the bag, the elongated section acting as an integrated filter member configured to allow insertion of an elongated air-extraction member of an air-extraction system inside the elongated section so as to extract air directly from inside the storage volume of the bag during the filling operation.

A displacement device for a handling device, including an articulation mechanism on which the handling device is accommodated, wherein the handling device is displaceable by the articulation mechanism between a first position and a second position. The articulation mechanism has a four-pivot arrangement with a first link and a second link, wherein the first link is connected to the second link via a coupler. The coupler has a receiving section for receiving the handling device, wherein the first link, the second link and the coupler are matched to one another so that a substantially rectilinear displacement of the handling device takes place from the first position into the second position. In a method for displacement of a handling device by such a displacement device, the handling device is displaced substantially rectilinearly by the articulation mechanism between the first position and the second position. A packaging machine includes the displacement device.

A displacement device for a handling device, having an articulation mechanism on which the handling device is accommodated, wherein the handling device is displaceable by the articulation mechanism between a first position and a second position. A pre-loading device is in operative connection with the articulation mechanism and/or the handling device to intercept the weight of the articulation mechanism and/or the handling device during displacement of the handling device between the first position and the second position. In a method for displacement of a handling device by such a displacement device, the pre-loading device unloads the weight of the handling device during displacement between the first position and the second position so that a continuous and reduced application of force moves the handling device. A packing machine for filling product like bulk materials into bags includes a filling module with a filling nozzle, a displacement device and a handling device.

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.
