| 20120096815 | METHOD AND DEVICE FOR FILLING A BAG - 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. | 04-26-2012 |
| 20120055533 | WIRE MESH - Wire mesh with warp and weft wires on a mesh surface with tube means spaced apart from each other being woven in on the mesh surface on which slat elements are located in order to serve for shading of the incidence of light. The slat elements can be provided with photovoltaic cells. | 03-08-2012 |
| 20110290369 | WIRE CLOTH - A wire cloth includes warp wires and weft wires which cross each other and are interwoven by a weave pattern. The warp wires are formed in at least two different configurations to define warp wires of first and second types. A length of the first type of warp wires deviates from a length of the second type of warp wires in relation to a particular length unit, with pores being formed in interstices between sections of two neighboring warp wires and crossing sections of two neighboring weft wires. | 12-01-2011 |
| 20110206301 | BAG WITH MEMBRANE - Bag for receiving bulk material and in particular cement, having a bottom seam and an opposite filling end wherein a receiving space is provided between the bottom seam and the filling end provided to receive the bulk material and formed by the bag wall. A de-aeration device is disposed in the bag wall between the bottom seam and the filling end for de-aerating the bag interior after filling. The de-aeration device comprises a semi-permeable membrane inserted in the bag wall. The membrane is air-permeable and water-impermeable. | 08-25-2011 |
| 20110136639 | DEVICE AND METHOD FOR PROCESSING OF FILM TUBES TO OPEN-MOUTHED BAGS AND FOR FILLING SAME WITH BULK MATERIALS - Device and method for processing open-mouth bags with a bag opening device for opening an open-mouth bag and with a valve inserting device which is suitable and intended to insert a de-aeration valve into a bag wall of the open-mouth bag. | 06-09-2011 |
| 20110128375 | PARTICLE MEASURING INSTRUMENT, IN PARTICULAR FOR THE ANALYSIS OF GRAIN SIZES OF FINE AND VERY FINE BULK MATERIALS - Particle measuring instrument and method for the analysis of particles comprising a dosing device which dosing device can be set into vibrations by means of a vibration generator for conveying, while segregating, particles present in the dosing chute to at least one outlet of the dosing device. Other than a first vibration generator a second, different vibration generator is provided for segregating the particles present in the dosing device. The second vibration generator generates vibrations of a higher frequency compared to the first vibration generator. | 06-02-2011 |
| 20110056585 | METHOD AND APPARATUS FOR FILLING OPEN CONTAINERS WITH A POWDERY PRODUCT - Apparatus and method for filling a container ( | 03-10-2011 |
| 20110047942 | PACKING UNIT - Packing unit ( | 03-03-2011 |
| 20100089490 | METHOD AND DEVICE FOR FILLING A CONTAINER - Method and apparatus for filling bags with loose materials, wherein a package to be filled is filled by means of a filling element through a filling process. The filling process comprises a filling stage, a settling stage, and a discharge stage wherein during the filling stage, loose material is filled into the bag while admitting air and in the settling stage, a settling phase is provided for the pressure to drop and in the discharge stage, the bag is discharged from the filling element. The filling process is shortened in that the available volume of the bag is reduced during the filling process to maintain the pressure prevailing in the bag high, while at the end of the filling process the available volume of the bag is expanded to rapidly reduce the pressure prevailing in the bag. | 04-15-2010 |
| 20090272460 | METHOD AND DEVICE FOR FILLING A PACKAGE - Method and apparatus for filling bags with loose materials, wherein a package to be filled is filled by means of a filling element in a filling process. The filling process comprises a filling stage, a settling stage, and a discharge stage wherein during the filling stage, loose material is filled into the bag while admitting air and in the settling stage, a settling phase is provided for the pressure to drop and in the discharge stage, the bag is discharged from the filling element. In the settling phase, the squeezing device applies a squeezing pressure to the package so as to vent the package and to reduce the volume available to the package, until a predetermined reduction of the volume available to the package is reached, whereupon the squeezing pressure of the squeezing device on the package is reduced and the package is discharged from the filling element. | 11-05-2009 |
| 20090235616 | CONTAINER FOR FILLING MATERIAL AND METHOD FOR THE PRODUCTION THEREOF - A container ( | 09-24-2009 |
| 20090205293 | FILLING MACHINE FOR OPEN, SEALABLE SACKS - A filling machine for open, sealable sacks includes a fill pipe for filling the attached sacks with contents having a tendency to develop dust, and a cleaning device which includes a blow rail for cleaning the inner faces of the sack mouth rim and side folds of a sack by an air flow which emerges from the blow rail. The blow rail is fastened to two-armed levers which can be pivoted about a stationary axis by means of a drive. As a result, the air jets are directed onto the surfaces to be cleaned from different directions during the cleaning process and the layers of the side folds are also separated from one another and cleaned. The filling machine is suitable, in particular, for filling powdery contents. | 08-20-2009 |
| 20080318750 | PACKAGING MACHINE AND DISCHARGING DEVICE FOR A PACKAGING MACHINE - Packaging machine and discharging device for a packaging machine, and a method for filling bags by means of a packaging machine, wherein a bag to be filled is filled by means of a filling element and the filled bags are taken off by means of a bag take-off device and transferred to a discharging device. The discharging device comprises a conveying device for conveying off the bags filled with bulk goods, wherein at least one monitoring device for monitoring the tightness of the filled bags is provided which is associated with the conveying device. Said monitoring device comprises a weight sensor which captures a measure for the bulk material escaping from a bag to determine a parameter for the bag leakiness. | 12-25-2008 |
| 20080257450 | Method and Apparatus for Filling Open Containers with a Powdery Product - Apparatus and method for filling a container ( | 10-23-2008 |
| 20080236105 | Method and Apparatus for Filling Bags - Method and apparatus for filling bags wherein bags are filled one by one with a filling material and thereafter closed by means of an oscillating structure of an ultrasonic welding device. A parameter for the oscillating behavior of the oscillating structure is determined at no-load between closing two bags. | 10-02-2008 |
