I know that someone here, at some point, has been involved in the design of whatever machine it is that twists bread bag ties. Please, for the love of God, righty tighty - lefty loosey!!
Nearly a life time ago, I worked as a tec (I was 21) in a bakery and it had machines that wrapped bread in wax paper, the machine was called a "BL5", not a PLC in the place, we had stackable logic blocks made by MTE I think.
