s/strips off/cuts off/, right ?

If the lengths are relatively short and repetitive, how about

Hold wires in with left hand, snip with right hand. Eject the
cut piece of wire by pressing down on the near end of back stop
(C) and inserting the wire for the next piece.

Better make longitudinal grooves in (A) so the tubes don't move
around too much.

The hardest part will be sourcing suitable tube. Straws and old
biros may be too big for 0.22 mm² wire. Unless you can put
several pieces of wire in the same tube ? Aluminium tubing of
that kind of size exists but PMMA or something transparent would
let you check that every wire has bottomed out.
