Resumen
Device for the treatment of canvases as an auxiliary tool to perform, among others, conservation-restoration treatments on painted canvas supports that include: - a frame, - a set of tension elements of the canvas by individually adjustable elements in each corner of the frame: pins (1), threaded rods (2), nuts (3), washers (13) and/or springs (15); - a magnetic system to achieve regulated and uniform tension on the surface of the canvas: a set of magnets (5) inserted in holes made in the outer edge of the slats (10) of the frame, a second set of free magnets, a metal plate perforated (6) that is inserted in metal gutters (4) located on the inner edge of the slats (10) and that, together with the second set of magnets, helps to expand the tension exerted at a certain point on the fabric towards a larger area, avoiding additional damage during treatment.
