摘要： In the production of a strand-form hotmelt adhesive wrapped in a tubular film which is suitable for simultaneous melting with the hotmelt adhesive and which does not have any surface tackiness at normal storage temperatures, the heated liquid hotmelt adhesive is introduced into the cooled tubular film and the tube is subsequently cooled in a cooling bath. During introduction of the hotmelt adhesive, the shape of the tubular film is stabilized by providing an excess gas pressure and/or a guide inside the tube. The outside of the tube is cooled by a cooling liquid, the tubular film is brought into a substantially horizontal position after immersion in the cooling bath and is kept in that position in the cooling bath at least until the contents of the tubular film in proximity with said liquid hotmelt adhesive have at least partly solidified. Strands of any diameter and any length can readily be produced without significant effort in an economically and industrially useful manner.
