Holder assembly for transfer device

Holder assembly (10) for holding a film tube (20) in a sealed manner, wherein

• the holder assembly comprises a first tubular element (11) which is adjoined by a second tubular element (12) separated from the first tubular element by an annular gap (13),
• wherein the first and second tubular elements jointly surround an interior (14),
• wherein a first clamping element (15) extends radially outwards around the first tubular element,
• wherein the first tubular element, the second tubular element and the first clamping element are configured such that the film tube can be guided out of the interior through the annular gap onto an outer side of the first tubular element, that the film tube can be fixed in a sealing manner along a first circumferential line (20′) of the film tube by the first clamping element against a first contact pressure surface of the first tubular element, and that the film tube can be fixed in a sealing manner along a second circumferential line (20″) of the film tube in the annular gap,
• wherein a gas outlet (18) opens out of the outer surface of the first tubular element in an area (17) between the annular gap and the contact pressure surface, and wherein the gas outlet is in direct fluid-dynamic connection (19) with an outer edge (13′) of the annular gap.
