French term
barre de rappel
French to English
Tech/Engineering
Engineering: Industrial
Paper machinery
Machine for producing 'cardboard cores' e.g. inside toilet roll. The cardboard tube comes out of the 'winding' bit and is then supported by the 'barre de rappel' which moves away from the machine so that the tube can be cut to length.
Pull-back mandrel? Withdrawal mandrel/bar? Or any other suggestions much appreciated.
TIA, Chris.

return pin
Would "return pin" be Ok.
Just a suggestion
Otherwise return barrel or a return bar

extender bar
[I am presuming there is a bar INSIDE the machine around which the spiral tube is formed.]
Is this barre de rappel separate from the machine, i.e. the end of a continuous spiral tube projects from the machine and is supported by a bar which "separates from" the machine a large enough distance for the tube to be sliced in the gap between the machine and the bar?
How is the tube subsequently removed from the bar? Does it tilt down so the tube slides off, or is it pivoted or retracted so that its end is clear enough of other objects for the tube to be pushed off?

"Bullet"????
Perkins refer to the "bullet" inside the tube against which the "knives" cut. See video: http://www.youtube.com/watch?v=LXiZssWT5lg
Presumably, though, this bar does not move. It appears that the chariot supporting the two cutting disks moves (disks still "engaged") to eject the tube from the support bar.

"Nylon sleeve" makes it sound very much like the principle shown in that video (but the bar does not move, as far as I can make out, other than in rotation, potentially). The tubes are fired off the end of the bar.

Note from asker:
Answer to your last question - don't know!! The barre de rappel has a nylon sleeve so as not to damage blades when they cut the tube, but can't for the life of me find out how they are removed. Answer to first question is NO they are not cut in the gap so can't fall |
'Bullet' it might be. Same principle as far as I can see, not sure how we get from extender bar to bullet. I'll ask client. Will keep you informed. |

support roller
"This works on the same principal as the single knife in-line cutters except that because we are using several knives to cut with, the tube is carried by servo driven support rollers. This is to ensure that each cut is complete without the various pieces "tailing" together."
