Claims5
A belt for transporting a load, comprising:
- a) a first ply, including a first width;
- b) a second ply, including a second width;
- and
- c) a flexible stratum, comprising:
- a permanent magnetic composition, wherein said flexible stratum:
- i) runs an extent of said belt;
- ii) is seated between the diametric peripheries of said first ply and said second ply;
- iii) can be induced to flux magnetically with a stator to push said belt;
- and
- iv) is of a width lesser than either said first ply's first width or said second ply's second width;
- and
- d) a first stretch limiting member joined to a first side of said flexible stratum and said first ply and said second ply.
