Method for making holes in a layer (1) of heat-fusible material, characterized in that a layer of absorbent material (2) is brought together with a layer (1) of heat-fusible material, following which the layers brought together are fed through a device for localized heating of the heat-fusible material, so that this melts, forming holes in this material, the molten material being absorbed in the absorbent material, the layer (2) of absorbent material is removed from the layer (1) of heat-fusible material after having absorbed molten material from the holes made in the layer of heat-fusible material.
