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: Apparatus and method of manufacturing open-mouth bags, comprising a storage device with a supply of bag film, a control device for controlling, a conveying device for conveying the bag film and/or the bag body along a conveying path, a welding device with welding means for making a bottom seam in the bag film and a cutting device with a cutting means for separating a predetermined film length of the bag film to form the bag body of an open-mouth bag. The control device controls the conveying device so as to cause a relative motion of the bag body and the bag film and a distance between the bag body and the bag film is generated prior to making the bottom seam. The control device controls the conveying device and the welding means so that while welding the bottom seam the welding means extend at least up to the bottom end of the bag body.

Abstract: A packaging machine and method for filling bulk materials into packages with a rotatable machine frame and a plurality of circumferentially arranged filling spouts. During frame rotation, bulk materials are filled into packages. A machine silo is configured at the machine frame which has a storage volume for storing a quantity of bulk materials for filling a plurality of packages. Bulk materials are filled into the attributed packages from the silo through the filling spout. The machine silo is connected with a material supply with a controllable closing member for feeding bulk materials to the machine silo. A controller controls the closing member of the material supply dependent on the fill level to reduce the height of fall of the bulk materials being fed into the silo, or to avoid a free fall of the bulk materials during the feeding of bulk materials into the machine silo.

The receiving box (30) comprises suction apertures (34) in a lower region (31a) and in at least one region (31b, 31c) above that which are controlled differently.

Abstract: Apparatus and method for filling flowable materials such as fluids and bulk goods into flexible open-mouth bags, the apparatus including a stationary part and a movable part wherein the movable part is provided with multiple filling stations. Each filling station has a retaining device fastened to the movable part. A plurality of handling stations are received and distributed at the stationary part. A handling station is configured to take over empty open-mouth bags and a handling station is configured for filling a bag. One handling station is provided with a weighing unit. A bag receiving unit is configured to receive and guide the bag. The bag receiving unit at the handling station equipped with a weighing unit can be temporarily decoupled from force transmission to the retaining device to enable separate weighing of the bag receiving unit with the bag.

Abstract: Apparatus and method for processing open-mouth bags comprising a handling device for exchanging open-mouth bags with a rotary packaging machine. The handling device comprises a rotating device that circulates around a rotation axis of the handling device and is provided with two gripping arms for gripping the open-mouth bags. The two gripping arms are disposed for separate, longitudinal movement transverse to the rotation axis of the rotating device to enable longitudinal movement of the gripping arms relative to the rotating device in addition to the circulating motion around the handling device.

Abstract: A packaging machine and method for filling bags with a supporting structure to which at least one filling box is fastened which includes a conveyor element and to which a weighing device and a filling spout are assigned. A control device is provided. The filling box is retained non-communicating with the supporting structure and the assigned filling box and is weighed separately by the assigned weighing device to discharge from the filling box a predefined quantity of intended fill product by way of differential weighing and to fill it into the bag through the filling spout. The control device controls the strength of a volume flow into the bag over the time of the filling process so that the intended fill product is maintained at a high fill height while overflow is simultaneously prevented.

Abstract: Rotary packaging machine and method for filling open-mouth bags with multiple filling units disposed over the circumference and rotating along, each of which having a filling spout with a filling opening to which the open-mouth bags can be appended by way of a motion oriented upwardly relative to the filling spout. A handling unit configured as a take-over device is provided for taking over the filled open-mouth bags from the filling units and comprises a gripping arm with a gripping unit provided thereat. The gripping arm is rotatingly disposed at the take-over device. The gripping unit is pivotally disposed at the gripping arm for performing relative to the gripping arm a pivoting motion superimposed on the gripping arm rotation.

Abstract: Apparatus and method for filling bags wherein the bags are gusseted and extend from a first end to a second end. The gussets are optionally pulled outwardly out of the second bag end by means of a spreader device to provide a large filling mouth. The bag is attached to a filling spout by its opened second end where it is filled at least in part before the second end of the bag is closed by means of a closing device by way of at least one closing seam.
