The STD-TE 72 Two Roller Machine has two motors, one to provide the input power and one to absorb the transmitted power. The design is of the “over-hung” roller type, with test rollers fitted over-hung on the end of the machine test spindles, as opposed to the “fully supported” arrangement, in which the test rollers are mounted on shafts between bearings, as with the STD-TE 74 Two Roller Machine.
