A high speed sheet working machine and a feed control apparatus therefor which is operative to precisely control the amount of material to be cut from a strip, fed from a roll, to form sheets with edges thereof in precise registry, as if stacked and trimmed all at one time. The feed control apparatus holds the strip in firm engagement with a feed roller which is rotatably mounted on a drive shaft engaged by an overrunning clutch to permit only feeding rotation of the feed roller, whereby the strip is intermittently advanced by the feed roller. Brake shoes engage discs on the feed roller for stopping same after a selected feeding advancement of the strip to avoid overruns and underruns of the selected feeding advancement.
