Frictional Feed Belt

This is to extend the life of a frictional feed belt using the principle of Mobius bands.

The frictional feed belt has many applications. In the figures, documents 1, e.g., papers, bills or checks are held in a hopper 2 and removed one at a time by a frictional pick belt 3 and a frictional restraint belt 4 guided by at least two pulleys 5, 6 and 7, 8, respectively.

The belt may be made of rubber, such as urethane rubber, NBR (nitril- butadiene rubber), etc, and its section is formed square. The ends of the belt material are joined or bonded to each other in a 90 degrees twist so as to form a kind of Mobius band. The twisted portion of the belt should be placed on a side opposite to the document contacting side of the belt.

In this Mobius band-like twisted belt, all of the four surfaces are used continuously as working surfaces, so the life of the belt will be extended four times that of the usual single-sided flat belt.

In general, if the section of the belt forms a regular N polygon, the ends of the belt material should be joined in 2 pi /N twisted form. If necessary, the twisted belt may be formed by a molding process instead of a joining process.
