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.

Process for production of hotmelt adhesives

To load products, particularly lipsticks or glue sticks, delivered upright from a packing unit, into a plurality of receiving trays, the products are grouped in at least two rows in a segregating station, conveyed in spaced groups to a transfer station, and moved to a filling station into a prepared tray by means of a handling unit equipped with a gripper means. Each tray, filled with products, is removed from the filling station by an output conveyor and is replaced with a similar empty tray while another group of products is formed and moved into the transfer station.
