Abstract:
A process for the production of a strand-form hotmelt adhesive comprising:(a) introducing liquid hotmelt adhesive into a tubular film, which tubular film is suitable for melting together with the hotmelt adhesive and which is not tacky at normal storage temperatures, to fill a portion of said tubular film with said liquid hotmelt adhesive;(b) cooling the outside of said tubular film by contact with a flowing cooling liquid in proximity to the point where said liquid hotmelt adhesive is introduced into said tubular film, whereby said tubular film is cooled while said liquid hotmelt adhesive is being introduced into said tubular film;(c) providing at least one member selected from the group, consisting of excess gas pressure and a guide inside said tubular film to stabilize the shape of said tubular film while said hotmelt adhesive is introduced into said tubular film;(d) immersing said portion of said tubular film in a cooling bath after filling said portion of said tubular film with said hotmelt adhesive, to cool said hotmelt adhesive.
