This invention relates -to an apparatus for and
a method of processing photographic sensitized
strip material and‘more particularly of processing
photographic paper in long strips. A convenient

A second method ofïprocessing photographic
paper is to run it in> a continuous strip through a 2

This method oi' photographic processing is
rapid and adapted to processing in large quanti
ties at a low cost. One disadvantage of this
method is that a small quantity of illm or paper
cannot be processed at a low cost, due to the fact
30 that large quantities of p
solutions are
` needed to till the large tanks. Another disad
vantage is the need for a' leader to keep the
machine threaded and still others are the large
space occupied by the machine and its cost of

construction. _

The third method of photographic pr
is the using. ot some form of holder that carries
