Abstract
Method for laying a band of elastomer of given width and given mean thickness on a receiving surface, comprising a step during the course of which a leader of elastomer band of given length, the neutral fibre of the cross section of which has a non-zero curvature, is extruded through a die, the said leader being supported only by its end positioned on the die side, characterized in that the band is orientated in such a way that the concave side of the said neutral fibre faces away from the orientation of the gravitational field, so as to prevent the leader from collapsing under the effect of gravity.

A method for laying a band of elastomer of given width (l)—and given mean thickness (e) on a receiving surface, comprising extruding through a die a leader of elastomer band of given length (s), the neutral fibre of the cross section of which has a non-zero curvature while said leader is supported only by an end positioned on the die side,
- wherein the band is orientated in such a way that said neutral fibre has a concave side that faces away from the orientation of the gravitational field, thereby preventing the leader from collapsing under the effect of gravity.
