A pair of rollers ( 2 ), constituting the seat and the traction means for the formwork ( 3 ) to be reinforced, are established on a bench ( 1 ). A pair of upper pressure rollers ( 12 ) act, at the same time, on the formwork. On the same bench ( 1 ) there are also placed, laterally with respect to the formwork ( 3 ), a pair of longitudinal guides ( 15 ) for the movement, in parallel to the formwork ( 3 ) of a carriage ( 14 ) wearing the fiberglass mesh delivering reel ( 13 ), said reel ( 13 ) being furthermore mounted on the carriage ( 14 ) with the possibility to rotate around the vertical axis, in order to vary the orientation of the fiberglass mesh with respect to the formwork ( 3 ). The carriage ( 14 ), at the end position on the guides ( 15 ), delivers the reinforcing band to the formwork ( 3 ) in a perpendicular way with respect to the axis of the latter, and after turning around the formwork ( 3 ) for some times, the carriage initiates the longitudinal movement while the reel ( 13 ) adopts an inclined position, until the opposed end of the formwork ( 1 ) is reached, at which moment it reverts to the perpendicular position and thereafter the direction is changed.
