Abstract
A longitudinal measuring device is disclosed which includes a flexible scale mounted inside a tubular member. The tubular member defines a groove having overhanging flanges on each side of the groove and the scale is positioned inside the groove. The width of the scale is chosen to be wider than the separation between the overhanging flanges, and the flanges serve to retain the scale in the groove in a longitudinally displaceable manner without applying distorting forces to the scale. Both the scale and the tubular member are independently mounted to a mounting surface such as a machine component, and the scale is mounted in such a manner that the separation between the ends of the scale can be expanded without dismounting the scale from the machine component.
