Abstract

PURPOSE: To facilitate curl degree measuring operation with the constitution through which extent of a curve can be read on a scale on a table, by holding a test piece by a clamping device so that the length direction and width direction are horizontal and vertical respectively.
CONSTITUTION: Striplike test piece A sandwiched between elastic pieces 10 and 11, such as rubber and felt, stuck to clamping pieces 5 and 6 on a horizontal table and tightened by screw 7 to hold it so that the length direction and width direction are horizontal and vertical respectively. Transparent cover 9 treated for charging prevention is placed and through scale 2, curve (a) of test piece A is read. Since test piece A has an accurate arc, radius (r) of curvature is determined by a=r[1- cos(l/r), where (l) is the effective length. Therefore, curl degree (1/r)×100 can be calculated. Thus, the measurement of the curl degree can be facilitated.
