Abstract
The present invention relates to a method for at least partially wrapping a piece-goods stack, in which a tubular portion is pulled over the piece-goods stack, and to an apparatus for carrying out the method according to the invention. The method according to the invention is distinguished in particular in that, during the pulling of the tubular portion over the piece-goods stack, pleats are produced in a specific manner in the tubular portion, said pleats extending obliquely over at least one side of the goods stack. The invention is achieved in terms of the apparatus in that the apparatus has a reefing device for reefing and/or drawing over the tubular portion, said reefing device being configured in such a manner that it reefs and/or unreefs regions of the tubular portion at different speeds and/or at different times.
