Abstract

Filamentary or thread textile material is wound onto lap creels (2), which are capable of being pushed, in a telescoping manner, one into the other to form stacks (3). Each stack (3) is covered with a film tube or hose (6) which is shrunk onto the stack for holding together the individually wound lap creels (2). Immediately prior to a treatment, several stacks (3) are formed into a column, which is compacted by an axially effective compression. The slackened tension of the film tube (6) is then re-established by renewed shrinkage thereof prior to or at the start of the treatment of the textile material. Film material capable of repeated shrinking, especially heat shrinking is used for this purpose.
