ANLEGGNING FOR SAMTIDIG, KONTINUERLIG TILLVERKNING AV FLERA KETTINGAR

摘要

Apparatus for the simultaneous manufacture of several chains by means of not less than three and not more than five operating stations (5-8) equally distributed about a circular course and serving successively to add a link to the chains and to perform the operations required to finish the link. A set of movable conveyors (11-14) equalling in number the operating stations carried by an annular supporting member (22) rotatable about the vertical axis of the course successively presents depending ends (1a-4a) of the chains to the operating stations. A set of stationary conveyors (15-18) receives the chains discharged by the movable conveyors and conveys them to points from which they can be withdrawn to localities remote from the manufacturing apparatus. The radial positions of said sets of conveyors with respect to the radial axis of the course are such as to allow each of the chains passing from a conveyor (11 to 14) of the movable set to a conveyor (15 to 18) of the stationary set to form a depending slack (1 b-4b) of sufficient length to allow the required angular displacements of the movable set of conveyors.
