  • Patent number: 4671755
    Abstract: Apparatus for controlling shoe production. A rotatable table has locations including last holders for receiving and holding a plurality of lasts. Each last holder extends upwardly away from its location. An endless conveyor, situated near the table, includes conveyor plates having last holders on which lasts can be mounted and dismounted. The conveyor plates and the locations occupy substantially the same horizontal plane. A robot, including a transferring device between the table and the conveyor, transfers lasts between the conveyor at a first transfer station and the table at second transfer station and visa versa. A shoe last rotating device rotates the lasts 180.degree. to reorient each last from the position it occupies on the conveyor to the position it occupies on the last holder. A holding device causes each last holder to retain a last after the last is transferred to the table at the second transfer station and to release the last at the second transfer station after the table has revolved 360.
