Wire tension controller for process line of unbonded pc strand

摘要

The present invention relates to a strand tension control on the PC eonbon bonded strand (strand unbonded pc) manufacturing line.; The present invention relates to a supply for the volume grease applied on the strand travel path between the odor device and plastic-coated device is installed so that the coating of the plastic coating layer, following the application of the grease carried on the surface of the strand is configured eonbon Extended PC strand manufacturing apparatus , a structure that the tension control device 20 to cause forward the supply is installed, in which the tension adjuster 20 is perpendicular to the upper end of the frame 21 and a frame 21 erected on a moving strand (W) support roller bracket 22 and a roller bracket 22, a plurality of movable rollers (23a) (23a ') roller group 23 consisting of the fixing roller (23b) (23b') (23b ') is mounted on that and, a central axis (23b'a) of the movable rollers (23a) (23a ') roller feed unit (24, 24 to the lifting movement of this to occur'), ​​and any one roller (23b ') of the fixing roller is coupled to the brake device consists of air 25, which controls the rotation of the roller.; In eonbon Extended PC strand manufacturing apparatus equipped with a tension adjusting device of the present invention the annealing of the strands did not constant vibration or shake fed from as feed (or chulreongim), even if the generation such a vibration and the like to the strand passes through a tension adjuster is attenuated or removed from the process, strand traveling between a tension adjuster and a winder has the advantage so that the linear movement of the running direction as well as minimize euroman that the winding defect and smoothly performed Plastic coating process.
