Abstract
A method and a device connects a partially flexible protective cover (2) sealed against the environment and forming a barrier between a contaminated area (12) and an uncontaminated area, to a partially flexible safety cover (20) by transferring the protective cover (2) out of the contaminated area (12) inverting the protective cover (2) over an opening such that its inside is turned out and then severing it from the safety cover (20) and closing the opening; or transferring the protective cover (2) from the contaminated area (12) by sheathing the protective cover (2) with the safety cover (20) as it is pulled through a passage and subsequently severing of both covers (2, 20) from the safety cover (20) and closing the sheathing; or pulling the protective cover (2) back into the contaminated area (12) and then sealing the ends shut to sever the safety cover (20) by forming a further sealed joint between adjacent film parts.
