  • FIG. 6 a partial elevation of the machine on line V-V in FIG. 1, during loading the roving cylinders.
  • FIG. 7 a side elevation of an end of the machine showing the roving cylinders.
  • FIG. 8 a side elevation of the laying hook in the open position the hook being driven by a motor
  • FIG. 9 the laying hooks in the closed position during arrival of the strand drawing-out and guide device.
  • FIGS. 1, 2 and 3 show the machine with two pairs of roving cylinders 3, 4 and 3, 4', driven by motor 1 through gearing 2 and which are provided with receiving eyes for the strands 7, 8, and for holding tight the strands against end closing pieces 6' of the clamping pistons 6 actuating the roving cylinders.
  • 9 is a hydraulic or pneumatically operated strand conveyor, whose cylinder-piston assembly 10 is fixed to a carrier 11 and whose piston rod forms the slide of the strand conveyor together with a support 13 on its outer end.
  • Supportl3 carries two strand feed tubes 14, 15, which are pushed through during the advance of the slides 12, 13 by the eyes 5 of roving cylinders 3, 4 and 3' 4'.
  • l6, 17 are strand reels on bearings on two bearing bars 18, from which the strand conveyor draws strands 7, 8. These run over rollers 20 carried on hearings on arms 19 of carrier 11 into the feed tubes l4, 15. 21 is a strand cutting shears arranged between the ends of feed tubes 14,
  • 23 are rails running in the longitudinal direction of the machine, on which on the one hand a guide trolley 24 (FIG. 1) and on the other a laying trolley 25 run.
  • the guide trolley carries a strand drawingout and guide device 27 on a bracket 26 projecting downwards, the device being fork-shaped in plan, and each leg of the fork carrying a strand grip 28, 29 with the legs of the grips projecting outwards upwards and downwards in a slanting direction.
  • FIG. 1 In the initial position of guide trolley 24, FIG.
  • the strand drawing-out and guide device is in the position ready to catch the two strand ends 7', 8 stretched between the roving cylinder pairs 3, 4 and 3', 4, FIG. 5.
  • the guide trolley 24 carrying the strand drawing-out and guide device 27 is connected by means of clamp 31 to the underside 30' (FIG. 7) of an endless driving chain.
  • the endless chain 30 runs on the one hand over a driving chain-wheel 32, to which a vee-belt pulley 35 is keyed on shaft 34 mounted in bearings on bracket 33, and which can be driven through vee-belt 36 and vee-belt pulley of driving motor 38.
  • the endless chain runs over a chainwheel at the other end of the machine, not shown.
  • the laying trolley 25 is pulled in the direction of the arrow by a rope 39 guided over rollers.
  • An electric motor 41 is arranged on bracket 40 of the laying trolley, the motor shaft 42 carrying laying hook 44, which is rotatable on spindle 43 and can be automatically actuated, and whose closing lever 44 can be forced into the closed or open position by striking against a fixed stop 45.
  • the laying hook 44 operates in conjunction with two closing tongues 46, when it passes through eyes 46 of the tongue ends, by which a secure take-over of the two strand loops 7, 8 from the strand drawing-out and guide device is ensured.
  • a receiving basket 47 is arranged along the machine on the fioor, into which the finished cords or ropes fall on simultaneous opening of the laying hook 44 and the clamping devices 6 of the roving spindles 3, 4 and 3, 4.
  • Guide trolley 24 is moved in the direction towards laying trolley 25 by switching in motor 38, when the strands 7, 8 are caught and drawn out by grips 28 and 29 of the strand drawing-out and guide device in the range between cylinder pair 3, 4 and cylinder pair 3', 4'. Strands 7, 8 are then tightened over rollers 20 and feed tubes 14, 15 from reels 16, 17.
  • Hook 44 then catches the strand loops 7, 8 which are guided between closing tongues 46 and holds them fast.
  • Clamping pistons 6 of the first pair of roving cylinders 3, 4 are now closed.
  • Guide trolley 24 travels a set distance back from laying hook 44.
  • Laying trolley 25 with laying hook 44 stretches the strand loops 7, 8 by means of the weight on rope 39 (FIG. 1).
  • Shears 21 now cut strands 7, 7 near the first pair of roving cylinders 3, 4 and leave a projecting strand end 7", 8" at feed tubes 14, 15.
  • Motor 1 now starts up and drives roving cylinders 3, 4 and 3', 4 through gear 2. Because of the shortening of strands 7, 8 taking place during roving, laying trolley 25 is pulled forwards against the action of rope 39, until by means of a stop, it reaches the set strand hardness.
  • Laying hook 44 commences to rotate. Guide trolley 24 at once travels up to the roving cylinders in its initial position. During rotation of laying hook 44, the laying trolley slowly moves forwards. The desired hardness of the cord is obtained by the laying trolley contacting a pre-set stop 45, and motor 41 of the laying trolley stops. At the same time, laying hook 44 and clamping devices 6 of roving cylinders 3, 4 and 3, 4 are opened, and the finished cord falls down into the receiving basket. immediately, the second run for another cord begins.
  • the machine described is completed by electromagnetic controls, limit switches, stops as well as pneumatic or hydraulic driving units for fully automatic operation, when the finished cords fall down into a receiving basket after the laying process, by opening of the strand clamping members of the roving cylinders and the laying hook.
  • a machine for the manufacture of cords and ropes, comprising motor-driven roving cylinders, strand clamps for said cylinders, a strand conveyor with strand feeders for feeding said cylinders, a travelling guide trolley having means for feeding strands drawn out from said roving cylinders in lengthwise loops and combining them with a rotating laying device of a laying trolley which is continuously under the effect of a tension device, said tension device being adapted to be drawn forward during the laying process by the entry of the strands or cords up to adjustable stops which determine the hardness of the strand or cord, whereby the cord can be manufactured entirely automatically with simultaneous determination of hardness and length.
  • a machine according to claim 1, wherein said strand clamps and strand conveyors are automatic, and a roving device formed by said cylinders and comprising strand cutters which operate automatically, and wherein said guide trolley is movable on rails and wherein said laying device is a rotating hook arranged on said laying trolley.
