You're right Mats,
The feed rolls (or feed cylinders) also made sure that only one round at a time was fed onto the loading tray. In fact they locked after turning for a quarter of a turn, and only unlocked again on run-out, after the fired cartridge had been ejected. Their function was roughly similiar to a revolving door found in hotels,etc.
The feed pawls, which pushed the rounds down past the feed rolls on run-out, can be seen in the Bofors gun fitted to the Hercules in Stellan's Bofors Gun thread, last page. The pawls just visible in the curved slot just beyond them are the Stop Pawls, which keep the rounds in place while the feed pawls are moving up past them to repeat the feed cycle.
The L70 had a tilting tray, raised at the front during recoil to allow the ejected cartridge to pass out underneath it, to then fall in place, ready loaded, during run-out for ramming.
This was one of the improvements which allowed the rate of fire to actually be doubled from that of the L60.
