Abstract:
A positioning device (38) for holding a flat flexible part, especially a sheet, on a positioning surface (46) is presented. It comprises a body (44) having a suction opening (50) for aspiring the part and a fluid port (52) being in fluid communication with the suction opening (50). Furthermore, an abutment protrusion (60) is provided on a connection surface (48) for abutting the positioning device (38) against a base part (28) to which it may be mounted. Also a sealing protrusion (64) is arranged on the connection surface (48) for compressing a gasket (42) being interposed between the positioning device (38) and the base part (28). A height (Ha) of the abutment protrusion (60) is bigger than a height (Hs) of the sealing protrusion (64). Additionally, a positioning assembly (24) is presented which comprises at least one such positioning device (38). Furthermore, a sheet material processing machine comprising at least one such positioning assembly (24) is introduced.
