How do they slice hot dog buns while they are still connected?
I've always wondered.
Hot dog buns are sliced using a special serrated blade/knife while the four pieces of bread are still connected. The slices come in fours and they go through the machine just as four pieces.
This was on recently on "How it's made" It's done while the buns are on the conveyor belt with a horizontal blade. Then the buns are sliced into the correct size for packaging!
