PCT No. PCT/SE85/00171 Sec. 371 Date Aug. 5, 1985 Sec. 102(e) Date Aug. 5, 1985 PCT Filed Apr. 12, 1985 PCT Pub. No. WO85/04687 PCT Pub. Date Oct. 24, 1985.A Venetian blind production machine comprises a punching station with at least two groups of punching tools (14) for punching lift cord holes in at least two successive Venetian blind slats in the free end portion of a metal strip (6) inserted in the machine. The punching station is followed by a combined mounting and separating station, said separating station comprising at least a corresponding number of separating punches (17) for simultaneously separating the Venetian blind slats for the same number of simultaneously produced Venetian blinds. The invention is based on the idea that the advances of the metal strip (6) along the machine bed (2) is to occur for continuous and maximum periods of time with a minimum of acceleration and retardation cycles during the Venetian blind production. |
