Method to produce artificial needle-shaped foliage (34) of the type comprising at least two longitudinal wires (16) twisted together so that, between the spirals defined thereby, a plurality of transverse filaments (35) are retained, able to simulate needle-shaped leaves, said method providing to use longitudinal wires (16) consisting of fibre rovings and comprising at least the following steps:

said rovings (16) are impregnated with polymerizable resin (19);
said rovings (16) are positioned and cut to size and said transverse filaments (35) are interposed between every pair of super-imposed rovings (16);
said rovings (16) are reciprocally twisted together and kept in a twisted position;
the resin (19) impregnating said rovings (16) is polymerized.
Machine to produce artificial needle-shaped foliage achieving the method as above comprising, in co-ordinated co-operation, at least an assembly (11) to feed said rovings (16), an assembly (12) to impregnate said rovings (16) with polymerizable resin (19), a making up assembly (13) and an assembly (14) to polymerize the resin (19) impregnating said rovings (16).
