Definitions

the object of the invention refers to a scraper blade, used in machines for varnishing metal sheets to prevent varnish from being deposited on the inner face of this sheet.
the tasks of replacing the cylinder are very complex and laborious, with a consequent loss of work time of the machine.
the scraper blade according to the invention does not produce wear because of the friction in the cylinder that it cleans; so that when a replacement is necessary because of the wear, the blade is changed more quickly, which is why the machine's working time losses are minimal.
the scraper blade is made of non-metallic material and its hardness is always less than that of the cylinder that it cleans.
it has a single-piece configuration provided with conformations in conjunction with those of the machine where it is mounted (with known anchoring means).
the content of the present application is a new invention involving an inventive step, which can be applied in the industrial sector.
the object of the invention is a new scraper blade used on machines for varnishing metal sheets, to prevent varnish from being deposited on the inner face of this sheet.
this scraper blade for metal sheet coaters is structured in a single-piece body (1) of non-metallic material, which defines in itself the necessary conformations (11) for an operational anchorage to the machine.
the material of which the blade is made according to the invention is hard plastic; although in the subject of the invention are included the embodiment of the body (1) of the blade in any material of hardness less than that of the material which is the cylinder that cleans it.
said conformations (11) for anchoring the blade in the machine are slots / cavities in "U" formed on the edge / rear edge (10) of the body (1), opposite the edge / edge (12). ) which defines the angle of attack for cleaning.
