An apparatus (1) and a method for controlling a pulling of an inflatable bladder (B) through an aperture (3) in a wall between a chamber (5) and a structure (7) arranged on an out-side of the chamber (5), wherein the apparatus (1) comprises: - a pulling mechanism (11, 11') for pulling the bladder (B) through the aperture (3); - a cutting device (13) for providing a slit in a portion of the bladder (B) after said portion having passed the aperture (3), the cutting device (13) being responsive to a resistance of the bladder (B) against passing through the aperture (3), so that the cutting device (13) is activated and provides the slit if the resistance exceeds a predetermined level.
