<p>PURPOSE:To perform the running test with high accuracy and continuously by adjusting continuously the slide-contact with a slide-contact member by a slide-contact adjusting guide roller moving along a loop track, when a running tape comes into slide-contact with the slide-contact member. CONSTITUTION:When a running tape 2 is wound round a cylinder 9, its winding angle theta is adjusted continuously by a slide-contact adjusting guide roller 10 moving along a loop track and it is run, and by an entry tape tension sensor 8 and a delivery tape tension sensor 12, a tape tension of the entry and the delivery of the running tape 2 wound round the cylinder 9 is detected. By the detection of the tape tension of these entry and delivery, a variation of frictional force generated between the tape 2 and the cylinder 9 at each winding angle thetais measured continuously and precisely extending over a wide range, and accordingly, a tape running test having high accuracy can be executed continuously extending over a wide range.</p> |
