No need to answer, as I don't want to clutter the thread. I'll not be buying any book because I live hand to mouth as it is. I'm trying to picture in my mind a very long conveyor with conductuion rollers that can only make contact with the backside of the film. Obviously, if the film is wet, then no rollers can ride on the emulsion side. Unless the machines are built where any tires on the front side are all aligned, and there are several sacrificial strips along the width of the roll, that are slit out later and thrown away.
