Abstract
A machine for needling a textile structure made up of a plurality of superposed layers comprises a vertically movable needling table, a needling head having a determined number of barbed needles and disposed vertically above the needling table, and drive means for imparting vertical reciprocating motion to the needling head, defining a low point of maximum penetration of the needles. Measuring means are provided in the machine located in the needling head to measure the position of the top surface of the textile structure at the low point of maximum penetration of the needles. The measuring means are preferably disposed in a midplane of the needling head perpendicular to an advance direction of the textile structure.
