Method and apparatus for manufacture of laminate of fibrous substance having electrophoretic charge
 A laminate of layers of dissimilar fibrous substances having an electrophoretic charge is produced by the electrodepositing technique in an apparatus comprising an inner electrode disposed horizontally and adapted to accumulate the aforementioned fibrous substances on the surface thereof and a plurality of electrodes of the opposite sign and as many electrodepositing zones for accommodating aqueous suspensions of the aforementioned fibrous substances both disposed horizontally and coaxially in a spaced relationship. The production of the laminate is effected by a method which comprises the steps of feeding at least to adjacent electrodepositing zones the aforementioned aqueous suspensions of fibrous substances causing the fibrous substances to be oriented in different directions at least in the aforementioned adjacent electrodepositing zones, and applying an electric potential between the opposite electrodes thereby allowing the fibrous substances to be accumulated on the surface of the inner electrode.
