Abstract: An apparatus and method for filling bulk materials into open-mouth bags is provided, which includes the following steps:
a) an open-mouth bag is placed beneath a filling spout of a filling station;
b) the filling spout is lowered and the open-mouth bag is appended to the filling spout;
c) the filling spout with the appended open-mouth bag travels upwardly so that the bottom end of the open-mouth bag is freely suspended; and
d) the filling process is started and bulk material is introduced into the open-mouth bag so that the freely suspended bottom end of the open-mouth bag unfolds.-

Abstract: A compaction station and method with a compacting device for compacting open-mouth bags filled with bulk materials includes a container with a tubular inner wall and a takeup space for taking up a filled open-mouth bag, and a support unit on a height-displaceable lifting device, wherein when the lifting device is in a lowered position the support unit is supported from beneath and when in an elevated position, it is suitable to take over a filled open-mouth bag from an adjacent conveyor device. A pressure plug that can be lowered from above is included which, when in a lowered position acts on the bulk material from above, and in an elevated position allows takeover of a filled open-mouth bag from an adjacent conveyor device.

Abstract: Filling unit (1) for a packaging machine (100) for filling bulk materials (50) into packages (60), and packaging machine with a filling unit (1), comprising a conveyor device (2), by means of which bulk materials (50) can be conveyed into a package (60), and a control device (3), which is suitable and configured to guide a filling stream (4) into a package (60). A fill level sensor device (5) including a sensor device (6) is provided, which is suitable and configured to detect a first fill level (7) and a second fill level (8) of bulk materials (50) in a package (60), wherein the first fill level (7) corresponds to a lower fill level than the second fill level (8). The control device (3) regulates the filling stream (4) by way of the fill levels determined by the sensor device (6). With the method according to the invention, the package is filled until the second fill level is detected. Then the filling stream is reduced until the first fill level is detected. Thereupon the filling stream is increased.

Abstract: Apparatus and method of manufacturing open-mouth bags (2), comprising a storage device (3) with a supply (4) of bag film (5), a control device (60) for controlling, a conveying device (6) for conveying the bag film (5) and/or the bag body (16) along a conveying path (7), a welding device (8) with welding means (9, 10) for making a bottom seam (11) in the bag film and a cutting device (12) with a cutting means (13, 14) for separating a predetermined film length (15) of the bag film (5) to form the bag body (16) of an open-mouth bag (2). The control device (60) controls the conveying device (6) so as to cause a relative motion of the bag body (16) and the bag film (5) and a distance (37) between the bag body (16) and the bag film (5) is generated prior to making the bottom seam (11). The control device (60) controls the conveying device (6) and the welding means (9, 10) so that while welding the bottom seam (11) the welding means (9, 10) extend at least up to the bottom end (23) of the bag body (16).

Abstract: Apparatus for manufacturing an open-mouth bag of at least one layer of a flexible bag material, and method of manufacturing a bag by such apparatus. The apparatus includes a shaping device with a shaping box in the contour of the bag shape to be formed, with a top end and a bottom end, a conveying device for transporting the bag material along the shaping box, a closing device for joining the bag material along the shaping box to form a tube, and a closing station for generating a bag bottom, which is disposed beneath the bottom end of the shaping box. A partial vacuum device is configured to generate intermittently, a partial vacuum. When manufacturing a bag, the bag material is draped around the shaping box in the contour of the bag shape to be formed as continuous material and is joined to form a tube by the closing device.

Abstract: A packaging system for filling bulk materials into packages, including a filling unit with a filling box, and a filling box for a filling unit of a packaging machine for filling bulk materials into packages, including an upwardly opened takeup space for a package, wherein the takeup space is laterally enclosed by side walls. A partial vacuum device is provided, which is disposed in a corner portion between the side walls. The method for filling packages provides for a package to be guided to the takeup space of such a filling box of a filling unit of a packaging system. The partial vacuum device is then activated for aspirating a flexible wall of a package into the corner portion between the side walls of the takeup space of the filling box.

Abstract: Packaging machine and method for filling dusting product such as bulk material into open-mouth bags via a filling process. The filling process is controlled by weight via a control device and a weighing device. A batching element conveys product and introduces it through a filling spout into an open-mouth bag appended for the filling process. The filling spout is connected with a collecting tank through a flow connection such that a pressure surge occurring during the filling process is utilized for transferring into the collecting tank the displacing air contained in the open-mouth bag and including the dusting product to receive and settle the displacing air in the collecting tank and to deposit at least part of the dust content of the displacing air in the collecting tank as deposited product.
