Versiegelungsvorrichtung für aseptisch befüllte Packungen unter keimfreien Bedingungen

摘要

The disclosed device is used for sealing the fastening seam (13) of an aseptically filled packaging (11) made of paper coated with synthetic material under sterile conditions in a clean room (12), wherein a driving mechanism (8) conveying in the direction of movement of a sealing bar (2) is coupled to the latter from behind and is permanently fixed to a support frame (1) and a counter bar (3) is rigidly fixed to the support frame (1) in front of the sealing bar (2) in the direction of movement (6). In order for the driving mechanism for the sealing device (7) to be able to work under sterile conditions without requiring a special hermetically closed housing and with the aim of enhancing operational safety and reducing maintenance requirements, the invention provides that the driving mechanism (8) should comprise a hydraulic cylinder which uses sterile water as hydraulic liquid and should have a piston rod coupled to the sealing bar (2).
