Abstract
A method of producing a measuring tape may include providing a tape measure blade having a first end configured to extend from a housing and a second end configured to be wound on a reel assembly, defining a first non-critical region from the first end to a start of a critical region, defining a second non-critical region from the second end to an end of the critical region, and modifying a mass per unit length of a portion of the blade such that a mass per unit length of the first and second non-critical regions is less than a mass per unit length of the critical region.

A method of producing a measuring tape, the method comprising:
- providing a tape measure blade having a first end configured to extend from a housing and a second end configured to be wound on a reel assembly;
- defining a first non-critical region from the first end to a start of a critical region;
- defining a second non-critical region from the second end to an end of the critical region;
- and
- modifying a mass per unit length of a portion of the blade such that a mass per unit length of the first and second non-critical regions is less than a mass per unit length of the critical region,
- wherein the first and second non-critical regions include cutouts formed in the blade to reduce the mass per unit length in the first and second non-critical regions.
A measuring tape device comprising:
- a housing having an aperture;
- a reel assembly;
- and
- a blade having a first end configured to extend from the housing through the aperture and a second end configured to be wound on the reel assembly;
- wherein the blade comprises a first non-critical region from the first end to a start of a critical region, and a second non-critical region extending from the second end to an end of the critical region,
- wherein a mass per unit length of a portion of the blade is modified such that a mass per unit length of the first and second non-critical regions is less than a mass per unit length of the critical region, and
- wherein the first and second non-critical regions include cutouts formed in the blade to reduce the mass per unit length in the first and second non-critical regions.
