Abstract

The invention relates to a method for needle punching a fibrous structure whereby the fibrous structure to be needle punched is driven forward in relation to a needle-punching head bearing numerous reciprocating needles which penetrate and subsequently exit the fibrous structure. The instantaneous feed speed of the fibrous structure decreases in response to the feed resistance exerted by the needles when the latter penetrate the structure and said feed speed subsequently increases with the retreat of the needles, such that the force exerted on the needles by the forward motion of the structure is limited, without said forward motion being completely interrupted during the entire duration that the needles are inside the structure. The feed speed can be decreased directly by means of the feed resistance exerted by the needles using a drive device with a transmission having a spring take-up that can absorb the decrease in the feed speed of the fibrous structure.
