Method and system for manufacture and filling with a sterile liquid of a tubular packaging

A system for manufacture and filling with a sterile liquid of a tubular packaging, comprising:

• a sterile filling device for filling the tube at least partially with the sterile liquid from a container,
• a welding device for dividing the tube into a number of tubular segments by successive welding operations, the welding device comprising a pressure exerting mechanism and an energy supply for exerting pressure locally on and supplying energy to the tube during each welding operation,
• a separating device for separating the tubular segments from each other at the position of welded seams formed by the welding operations, and
• a displacing mechanism co-acting with the welding device for displacing the tube over a distance corresponding to a desired length of the tubular segments, or a multiple thereof, after each welding operation,
• wherein the pressure exerting mechanism and the energy supply of the welding device can be activated at least partially staggered in time.

• wherein a controller is connected to the welding device and the measuring device for controlling the welding operation on the basis of the measured value of the at least one welding parameter.

A method for manufacture and filling with a sterile liquid of a tubular packaging, comprising:

• providing a container with the sterile liquid therein,
• providing a tube,
• filling the tube at least partially with the sterile liquid, in sterile manner, from the container,
• dividing the tube into a number of tubular segments by means of successive welding operations, and
• separating the tubular segments from each other at the position of welded seams formed by the welding operations,
• wherein after each welding operation the tube is displaced in controlled manner over a distance corresponding to a desired length of the tubular segments, or a multiple thereof, and
• wherein at least one welding parameter is measured during each welding operation, and the welding operation is controlled on the basis of the measured value of the at least one welding parameter.
