Abstract
1,028,855. Taking up slack in flexible supply leads. GEWERKSHAFT EISENHUTTE WESTFALIA. Aug. 4, 1964 [July 29, 1963], No. 31146/64. Heading B8B. In a method of guiding and taking of slack of energy supply leads 12, 13, Fig. 1, for a coalwinning machine 9 the leads are connected to a fixed point 22 near the centre point of the coal face and pass over return pulleys 23, 24 on a carriage 14 movable at half the speed of the machine 9 and driven by a traction cable 15 attached to the mining machine 9 or to the idle run of its drive chain 20 as at 19, Fig. 2 (not shown). The traction cable 15 is attached at the other end to a fixed point 16 preferably through a spring 25 and passes over return pulleys 17 on the carriage 14 and a fixed pulley 18 at one end of the long wall face.
