@skywatcher:   It is not toothed and never was. It is simply a flat belt.

@M. Holmes: The pulley surfaces are straight and do not appear to have a convex shape.   The smaller pulley on the motor has a large shoulder on the motor side but other than that, there are no lips or ridges to hold the belt in place.
 
Interesting idea using the motorcycle inner tube.   If I can find one with the right diameter, I will give it a try.  Another thought might be to apply rosin to the belt.   What I have got to lose.  It is time to get creative for sure.
 
Thanks for your replies and ideas.

My apologies for taking so long to reply, particularly when you replied so quickly.  
 
@shywatcher:  The dimensions of the belt are 11 inches (28 cm) long by 5/16 inches (8 mm) wide by .048 inches (1.22 mm) thick. It is a flat belt and appears to be made of some sort of flexible plastic as opposed to rubber.  It is a translucent yellowish brown color, although the coloring might be due to ageing.   
 
It is an electric typewriter and it is a drive belt.   If I posted in the wrong forum and it should be in electric typewriters, my apologies. If a moderator wants to move it, that is fine with me.   Without giving it much thought, it seemed since I was trying to fix the typewriter, the section for repairs seemed more appropriate than a more general forum.

I have an Apollo 10, Model SP-8000, in house that the drive belt comes off the pulleys from time to time, particularly if the strikers happen to jam.    Examining the belt it appears to have dried out and lost a lot of its elasticity.   That is strictly a guess however as I have never seen another belt to judge it against.  Another guess is that there are no new belts available, and even if there were, they might be new old stock, i.e., the same vintage as the current belt and in the same condition.
 
Has anybody in this forum experimented with belts meant for other applications and devices as a substitute drive belt and had success?
