English to French Tech/Engineering Engineering (general)

Il s'agit du manuel d'utilisation d'une cercleuse avec presse et je ne sais pas trop quel terme utiliser pour traduire "bunk". Merci pour vos idées.

"bunk feeder", "bunk lifter", "bunk magazine", "bunk feeding".

Exemples dans contexte :

Hidden movements (bunk feeding before strapping cycle)
1. Bunk feeding can begin when strapping/press cycle is done and bunk detecting photocells S5.0 and S5.1 are not detecting bunk. Press gives line ready for hidden movements signal.
2. Bunk feeding begins when start hidden movements signal comes from line.
3. When bunk feeding is done press gives end of hidden movements signal to line.
4. Strapping/press sequence is now done without bunk feeding.
