Abstract: A positioning device (38) for holding a flat flexible part, especially a sheet, on a positioning surface is described. It comprises a body (44) with a fluid inlet port (52) for supplying a driver fluid to the body (44), a fluid outlet port (58) for draining the driver fluid from the body (44), and a suction opening for aspiring the flat flexible part. A circulation channel (60) connects the fluid inlet port (52) and the fluid outlet port (58) and a suction channel (70) connects the suction opening to the circulation channel (60). The suction channel (70) is connected to the circulation channel (60) adjacent to a section (64) of reduced cross section area such that a jet pump (71) is formed. Every cross section (Sc) of the circulation channel (60) and/or every cross section (Ss) of the suction channel (70) along its entire respective length have/has a smooth rim. Additionally, a positioning assembly comprising at least one such positioning device (38) is presented. Moreover, a sheet material processing machine is introduced which comprises at least one positioning assembly.

Abstract: The invention relates to a blanking station comprising a blanking tool (12), at least one blank receiving unit (14, 16) for receiving and piling of blanks (20) in a blank collecting space (22) in a piling direction, and at least one flexible guide (18), located between the blanking tool (12) and the receiving unit (14, 16), wherein the flexible guide (18) comprises at least one guiding surface (32) adapted for guiding the blanks (20), being oriented in parallel to the piling direction and arranged so as to define an outer contour of the blank collecting space (22), and wherein the flexible guide (18) further comprises at least one flexible portion (28), located in proximity to the blank receiving unit (14, 16), wherein the flexible portion (28) is elastically deformable in a first direction along the outer contour of the blank collecting space (22) and wherein the flexible portion (28) has a lower stiffness in the first direction than in a second direction perpendicular to the outer contour of the blank collecting space (22) to avoid deflection of the flexible portion (28) into the blank collecting space (22) in case of collision with a blank receiving unit (14, 16). Furthermore, the invention relates to a flexible guide for guiding blanks (20) in a blanking station (10).

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.
