SECTION OF EQUIPMENT FOR PHOTOPROCESSING Russian patent published in 1994 - IPC

FIELD: photography. SUBSTANCE: section is designed for use in equipment of continuous transportation of sheet and roll photomaterials. Section includes processing chamber 1 with pulling element 2 located in it. Chamber 1 has loading 3 and unloading 4 openings in front and rear walls. Pulling element 2 is manufactured in the form of pair of loop transportation belts (outer lower one 5 and inner upper one 6) and loop formers in the form of loop rollers 7 and turning elements 8, tension rollers 9 and driving rollers 10, 11. Loops of inner upper belt 6 are arranged in spaces between loops of outer lower belt 5. Adjacent branches of outer lower belt 5 and inner upper belt 6 are loading ones and are mounted with clearance with reference to each other. Chamber 1 is provided with elements 16, 17 of horizontal deflection arranged in staggered order along load branches of outer lower belt 5 and inner upper belt 6 to render them zigzag shape. Outer lower belt 5 and inner upper belt 6 are fitted with cross-pieces 18 attached with spacing. Elements 16 of horizontal deflection are fabricated in the form of rollers positioned on both side of pulling elements 2 and elements 17 manufactured in the form of pairs of wheels are placed between belts of pulling element 2, close to edges. Turning elements 8 produced in the form of pairs of wheels. Cross-pieces 18 are mounted for interaction with elements 16, 17 of horizontal deflection and turning elements 8. Rows of elements 16, 17 of horizontal deflection of adjacent loading branches of outer lower belt 5 and inner upper belt 6 are positioned with partial spatial overlapping. EFFECT: increased quality of processing of photomaterials, access of processing solution to photolayer, prevention of fouling of processing solutions by pulling element, provision for change of operational processing procedure. 2 cl, 3 dwg
