<p>Machine for applying a fiberglass reinforcement to disposable formworks for columns, particularly for formworks provided with a tubular body, preferably made of expanded polystyrene, having a sealing inner coating and an external coating or reinforcement made of a band of fiberglass mesh rolled up helicoidally on said tubular body, characterised in that it includes, on an elongated bench (1), which dimensions are according to the dimensions of the formwork (3), a pair of longitudinal rollers (2) constituting a seat for said formwork (3) and being conveniently motorized in order to confer a rotational movement to the formwork (3) with the assistance of upper pressure rollers (12), having also a carriage (14) on said bench (1), movable in parallel to the rollers (2-12), wearing the fiberglass mesh delivering reel (13), with the special particularity that said reel (13) is mounted on the carriage (14) having the possibility to rotate around a vertical axis (18) in order to vary the angle of the continuous band of fiberglass mesh with respect to the axis of the formwork (3), enabling the helicoidal rolling up in both directions as well as the rolling up perpendicular to the formwork (3), particularly at the ends of the same, the reinforcement delivering reel (13) being furthermore assisted by an automatic brake against which the traction rollers (2) are acting, in order to confer the appropriate tension to the fiberglass mesh during its rolling up on the formwork (3).</p> |
