Abstract
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.
