ABSTRACT A process is provided for the production of an ordered web from at least one fibrous strand, compri- sing forwarding a strand towards a collecting surface, im- parting an oscillatory motion to the strand at a point above the collecting surface, characterised in that the oscillating strand is passed between two closely spaced plates which are substantially parallel to each other and to the plan of strand oscillation and which extend subs- tantially from the place of oscillation down to the collec- ting surface whereon the strand is laid substantially parallel to the preceding lengths of the strand. Also according to the invention apparatus for laying down a fibrous strand in substantially parallel cour- ses comprises means for supplying a fibrous strand, means for forwarding the strand, means to impart an oscillatory motion to the forwarded strand and a collecting surface whereon the strand is laid, characterised in that the appa- ratus includes two closely spaced plates which are subs- tantially parallel to each other and to the plane of osci- llation and which extend between the oscillating means and the collecting surface.
