Machine for the simultaneous laying down and winding of a plurality of individual fiber rovings

Machine for simultaneously winding/laying down of a plurality of individual rovings, comprising:

• a gantry;
• a laying down/winding head carrier mechanism plate supported by said gantry and movable in three Cartesian directions;
• at least one laying down/winding head rotatably mounted on said mechanism plate around at least one vertical axis;
• a laying down/winding roller rotatably mounted on each said at least one head, and movable with respect to an element to be covered;
• means for presenting rovings on each said roller positioned as at least two tangential laps;
• means for driving each roving and means for cutting each roving, said means for driving and said means for cutting being selectively activated;
• a plurality of spools mounted on a fixed creel for delivering rovings to said at least one head;
• and
• sets of return pulleys structured and arranged to guide the rovings between the fixed creel and said at least one head, said sets of return pulleys comprising a first set of fixed pulleys having a horizontal axis adjacent to a ground surface and perpendicular to said element to be covered;
• a second set of pulleys integral with a carriage supporting said head carrier mechanism plate having an axis parallel to said horizontal axis, said first set of fixed pulleys and said second set of pulleys being structured and arranged so that the rovings between the first and second sets of pulleys move along a substantially vertical plane, in accordance with movement of said at least one head;
• and cascade pulleys integral with said carriage for feeding said rovings from said second sets of pulleys to a set of pulleys integral with said head carrier mechanism plate and disposed vertical to said at least one head.
