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.

[ What is claimed is:] [1.] A fixture for measuring the length of long flexible extruded parts of different cross-sections, said parts being formed of foam rubber and the like material and being incapable of self-support in a straight line, comprisingan elongated cradle including an upwardly open trough,a plurality of rollers having rims of like diameter arranged with said rims aligned seriatim in said trough to present a series of support surfaces arranged in a line,support shafts for said rollers extending through the axis of rotation of the corresponding rollers,said shafts extending parallel to each other and transversely of said trough and being spaced apart a distance slightly greater than the diameter of said rollers whereby the circumferential rim surfaces of said rollers facing upward in said cradle provide a part support of discontinued segments of said rollers extending at least the full length of the parts placed thereon, and localized tension and compression in the part will dissipate due to the part being supported independently at relatively closely spaced increments along the length of the part,a scale attached to and extending along said trough,an end stop at one end of said trough for indexing a part placed thereon, anda floating stop movable along said rollers into engagement with a free end of a part and cooperating with said scale to indicate the length of a part.
