Patent number: 7861499Abstract: 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.Type: GrantFiled: March 7, 2007Date of Patent: January 4, 2011Assignee: Haver & Boecker oHGInventors: Alois Combrink, Josef Van Bergerem

Publication number: 20100089490Abstract: 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.Type: ApplicationFiled: November 26, 2007Publication date: April 15, 2010Applicant: HAVER & BOECKER OHGInventor: Alois Combrink
