ABSTRACT:
A roller measurement fixture is comprised of a series of small in-line rollers mounted in one or more rows, forming a receiving cradle device. An extruded part to be measured is cradled in a semi-circular arrangement of the rollers and straightens as it settles under its own weight. The cradle device will accommodate many different cross-sections of extruded seal. The rollers are free to rotate as the part is placed into the fixture and properly located. Friction front these rollers is negligible, therefore the part remains in, or attains, its free state, without internal stresses, throughout the loading and measurement process. Thus, the extruded part is limp within the cradle, being loaded so as to contact a head or alignment stop at one end of the cradle. A floating stop riding on the rollers engages the other end of the part and cooperates with a scale on the cradle as a means of acquiring the measurements.
