Abstract
A measuring device for measuring the thickness of fiber bundles such as slivers or the like on high output speed drawing frames within a predetermined tolerance range. The fiber bundle thickness is measured by a pair of rollers, one of which is supported for rotation about a fixed axis and the other of which is supported for rotation about a movable axis which permits it to move towards and away from the roller on the fixed axis. At least one of the rollers is composed of a material having a low coefficient of heat expansion under the temperatures generated when the bundle of fibers passes between the pair of rollers at high production output speeds. This avoids distortions in the measurement of the thickness of the fiber bundle.
