摘要

Improvements to die heads with a slot outlet for applying hot-melt products, of the type in which two dimensioning means (2 and 3) are arranged in the outlet slot (1) for the product which are capable of being moved closer together or further apart to adjust the width of the outlet, having a central passage (10) for feeding the product to the outlet and passages (11 and 12) via which the product is fed to the same outlet through each of the mechanisms (4 and 5) for displacing the dimensioning means (2 and 3), in such a way that said passages (11 and 12) move together with the dimensioning means (2 and 3), always keeping the product feed inlets within the part of the outlet selected for application.
