I suppose you are referring to a "Carpenter's Tape", one that is wound inside of a 4" x 4" metal case. If that is correct then, the carpenter needs the tape to be rigid as it is extended for vast distances. The slight width-wide curve gives the metal tape more rigidity thus allowing the carpenter to obtain accurate measurements.

Tachometer for measuring how fast something is spinning
What are open reel tapes?
Hi, Open reel tapes are equivelent to tapes like used on the older reel to reel tape recorders. They used to have open reel tapes for audio and video recorders. Many are still in use today. Open reel tapes had to be hand threaded through the tape transport whereas a cassette tape is self contained and the transport handles all the unloading and loading functions. Hope this helps, Cubby
