摘要： This invention provides a U-shaped pathway for cut film and prints as the cut sheets are automatically moved in a prescribed manner, path and speed through a processing tank or tanks. This transport is between rollers which are spaced from each other sufficiently so that any potential squeezing or pressing on the emulsion surface of the film is safely absent. Large rollers are arranged in three vertical columns and provide the down and up travel path of the film. At the bottom of this transport path a large roller provides an inside guide for the film. A series of small rollers provide an outer guide path for the U-shaped transport section of film. These small rollers are driven as are all the other rollers but this outer U-guide is formed of short rollers arranged in an intermeshed pattern to provide a closely guided contour. Short small rollers are carried in spaced array on common shafts. Like sized rollers in a like spaced array on an adjacent shaft are mounted so as to fill the provided spaces between the rollers so that in intermeshed arrangement the driving contact surfaces provided by the rollers are spaced approximately one-half the diameter of the small rollers.
摘要翻译：本发明提供一种用于切割薄片和打印件的U形通道，因为切割片材以规定的方式自动移动，路径和速度通过处理罐或罐。这种运输是在彼此间隔开的辊之间进行的，使得任何潜在地挤压或压在膜的乳液表面上是安全的。大型滚轮设置在三个垂直的立柱上，并提供胶片的向下和向上行进路径。在这个输送路径的底部，一个大的辊子为胶片提供了一个内部导轨。一系列小型滚筒为薄膜的U形传送部分提供外导向通道。这些小辊子与所有其它辊一样被驱动，但是该外部U形导轨由布置成相互啮合的图案的短辊形成以提供紧密引导的轮廓。短小的滚轮在公共轴上间隔排列。安装在相邻轴上的类似间隔排列的类似尺寸的辊子，以便填充辊之间提供的空间，使得在相互啮合的布置中，由辊提供的驱动接触表面间隔开大约是小辊直径的一半。
