Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
133 words
A leader belt stabilizer for use with a photographic processor of the type including: a plurality of processing tanks, a plurality of spaced apart belt engaging rollers in said tanks positioned to define a predetermined belt path through said tanks, a leader belt passing successively around said rollers and following said path, a cantilevered attachment arm removably connected at one end to a selected portion of the belt to transport a strip of photographic material through said tanks, said stabilizer comprising: a belt engaging stabilizer member immediately ahead of selected belt engaging rollers and aligned with the defined belt path to engage the belt portions located immediately ahead of the selected rollers and align said engaged belt portions with the rollers and substantially remove the twist in the belt ahead of said rollers.
Claim 2
Dependent Claim
