Abstract
An installation includes a carding machine ( ), and a distributor-layer ( ) depositing the card ( ) web ( ) in a reciprocating motion on a delivery belt ( ) moving transversely. The resulting intermediate lap ( ) is conveyed to a needling loom ( ) to produce a consolidated lap ( ). A measuring station ( ) scans the consolidated lap ( ) profile and transmits it to a processing unit ( ) where the profile is compared to a set reference input by a terminal ( ). The variations in width cause a corresponding modification in the width deposited by the distributor-layer ( ) by a link ( ). The local surface weight variations cause a corresponding modification of the controls applied to the carding machine ( ) capable of longitudinally profiling the web ( ). The invention is useful for controlling an installation for obtaining a finished product.
