I wouldn't keep the string around my wrist. If the top nip would start for some reason, you could be in big trouble. Also, I've worked as an extruder operator for 25 years, and I've never experienced a situation where I needed safety goggles.
@@carreramathew why do u use rope instead stick it straight to the bubble ? And why u dont block top and blown up at first but start with thick tube puling up... waste of time and material... with good nips motor u can start evan 15 m/m with ready film straight away... thin and wide...
