<p>PURPOSE: To stably feed the cable, even when it is composed of twisted cables, by introducing a structure consisting of a swinging body which swings in the running direction of a cable and a plurality of pressure cables. CONSTITUTION: A pressurized swinging mechanism is provided with upper and lower plates 23A, 23B on which small holes are bored at the upper part of the shafts 21, 21 and a swinging and supporting plate 24 arranged therebetween. When a triplex cable to be extended runs allowing its position to gradually displace in the crossing direction of the cable, a force in the cable crossing direction is applied to the pressurizing axis 31 via the pressure cables 38, 38 placed in contact and thereby the pressurizing axis 31 swings while it is moved gradually. Therefore, both pressure rollers 38, 38 swing following displacement of the cable body and displace to the position capable of giving the pressure. Meanwhile, when the cable body changes its height position along the running direction, the swinging plates 37, 37 follow to swing. Thereby, the cable body is always pressed to both pressure rollers 38, 38. As a result, the cable is stably extensively fed without generation of slip.</p> |
