ABSTRACT:
The present invention provides a novel carding machine for preparing a continuous non-woven fibrous web. This machine is comprised of a succession of carding cylinders including a first carding cylinder and subsequently a final carding cylinder; said cylinders are in communication with one or more carding rolls—doffers and/or randomizing rolls arranged in juxtaposition and rotate wherein their axes horizontal; at least one feeding inlet unit in communication with said first carding cylinder; and at least one product outlet in communication with said last carding cylinder, wherein one or more product outlets commenced form said carding succession, previous to said final carding cylinder, The present invention also provides for a cost effective method for maintaining fiber density on the carding cylinder while increasing production rate of the machine through the discharge of a certain amount of fully opened fibers from the cylinder.
