<p>PURPOSE:To make it unnecessary to watch the operation of the major line drawing by detecting the backlash of the line with a detector on the way where the major line drawn is sent to the line chamber. CONSTITUTION:A couple of the top and bottom detection rollers 11, 12 are almost adjusted its interval to the thickness of the major line A, and the major line is guided from the top of the fore guide roller 9 through the detection rollers 11, 22, and the rear guide roller 10 into the line chamber. When the backlash A' on the major line A lifts the detection roller 11, the swing lever 15 swings to start the switch 10 on the detector 17 whereby the line-drawing machine stops.</p> |
