Abstract:
In a method for filling and sealing a tubular or bag-shaped casing packaging, in which a shirred tubular or bag-shaped casing is disposed about a filling tube having an orifice through which filling material is discharged, with one of said casing being disposed over said orifice and sealed and filling is discharged through the orifice of the filling tube into the tubular or bag-shaped packaging casing, causing a portion of the shirred casing to be unshirred and withdrawn from over the filling tube and filled, after which the withdrawn and filled portion of casing is sealed, the improvement which comprises sealing said filled casing by the steps of:a) applying a compression force to a section over an entire width of said withdrawn casing adjacent to the filling tube to displace filling from said section;b) withdrawing said compression force from said section; and thenc) sealing said section with two closure clipsd) crimping said section of casing by applying two crimping shears to said section at the moment the withdrawing of said compression force is completed, a first crimping shear being applied to said section of casing at a position adjacent the filling tube, and a second crimping shear being applied at a position adjacent the side of the first crimping shear that is farthest away from the filling tube;e) displacing said second crimping shear away from said first crimping shear in a direction along a length of said filled casing to form a length of unfilled casing between said crimping shears; andwherein said sealing clips are applied to said length of unfilled casing between said crimping shears, and said crimping shears are then removed.
