Looks like a ships wheel type spoke assembly (6 spokes?). Round cross section spokes (my mind see's it as round during video play), with rounded over radius ends (to prevent grabbing things like clothing ).
It looks like it's used to help assist the machine (I see a rotating cylinder 6" diameter, maybe 10 wide) that looks inline with the shaft that spoke wheel is connected too. I would believe there's a mate for that roller for flattening out noodles or egg roll type "lefse" food. If thick doe overloaded the power drive, assuming an operator feeding product material in the opening above the rollers. Or did they take a manual machine and power it with a direct motor shaft to gear box reduction. There should have been a belt that slipped with her whole body mass being picked up. That coat was not going to tear off without killer her. Looks like nylon/rayon tough material. And somehow her right arm did not get snapped off, while being tangle in the frame of the main machine. What was that in her hand that the machine removed, as it does not look like she volunteered to drop it.
