<p>PROBLEM TO BE SOLVED: To enable easy and simple wirelike substance winding work by combining a feed screw which rotates interlocking with the rotation of a rotating barrel, with a nut composed of split nuts integrated by an energizing means, and moving a weight block. SOLUTION: The balance of the whole lashing machine is adjusted, by moving a weight block 530 in a balance unit 500. If a worker grips a hand lever, on this occasion, a female screw separares from the other female screw mutually, and the weight block 530 becomes in a free state to a threaded shaft 520. By moving the weight block 530 properly in this state, it is balanced with a reel. And if a hand lever is returned to its initial position after adjusting the balance, female screws 536, 535 are screwed on the threaded shaft 520 by the energizing force of a coil spring 538a. Consequently, wirelike substance winding work becomes safe and simple.</p> |
