摘要:
Systems for welding films to an insert piece to form a bag and for carrying out an additional processing step, for example to fill the bag, usually involve a transfer from one transport means to another. The invention proposes continuous means for the welding station and an additional processing step and also discloses practical options for implementation. The system is not only cost-effective but also very compact.

The aim of the invention is to avoid the risk of contamination of a bag for medical purposes, in particular to significantly reduce the amount of residual particles of material during the cutting of a tube for access to the bag. The invention proposes a system (1) for producing a bag for medical purposes comprising a tube transfer station (2) having transfer means (3) for transferring a tube (11), which is being transported towards the tube transfer station (2), to a holder (10) and for separating there a tube section (17) transferred to the holder (10) from a remainder (18) of the tube (11), in order to then render the separated tube section (17) connectible to two film layers to form an access to the bag. The tube transfer station (2) comprises at least one air nozzle (55, 57), and an effective area (58) of the at least one air nozzle (55, 57) is directed onto a designated location (20) for separation such that a forced air flow (56) in the designated location (20) forced by air blown out and/or drawn in can be adjusted for separation.
摘要:
The invention relates to an apparatus for welding a joining region of a foil to a connecting part, particularly two foils to a tubular connecting part. Conventional apparatuses are associated with the risk of steep workpiece flanges causing uncontrolled weaknesses in the foil and the weld seam. According to the invention, an extension of the foil outside of the joining region is provided in a controlled manner such that the foil has spare length. In this connection, the invention further relates to the use of a foil, to a method for welding, to a system for producing bag, and to a bag.
