A tool for processing of arc elements made of mortar and plaster. In order to have the most proper treatment of arc elements which are being processed in different kinds of mortar and plaster we use the lever (4) which bears via the scraper bearer (8) the lower scraper (9) and one of the side scrapers (12),(22) or (25), and centricaly is connected through the groove (6) to the shaft (5) of the lever bearer (2) which is fastened to the tool bearer (1), so that by swinging it to left and right while holding the handle (7) we simply and easily remove the excess of previously thrown-on material, achieving that by edges and overlapping surfaces (34) and (32) which are positioned on the lower scraper (9) and side scraper (12). After each removal, the remaining rough spots are filled in with new material and the procedure of removing by swinging of the tool is repeated until the edges and surfaces are completely smoothened. |
