  • System and method for producing a bag for medical purposes
    Patent number: 11523971
    Abstract: In order significantly to reduce the risk of contamination of a bag for medical purposes, in particular due to residual particles of tube material caused during 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) with a transfer means (3) for transferring a tube (11) coming into the tube transfer station (2) to a holder (10) and for the severing there of a tube section (17) transferred to the holder (10) from a remaining portion (18) of the incoming tube (11) in order subsequently to be able to make the severed tube section (17) connectable to two film layers for forming an access to the bag, wherein the tube transfer station (2) has a tube-tension-holding means (15) on the holder side and also a tube-pulling means (16), which means are designed to introduce tensile forces (19) between the severed tube section (17) and the remaining portion (18) of the incoming tube (11) while the severing takes place.
