The picker knives travel in an arc and not in a
flat plane parallel to the card line. For this reason,
to obtain the best possible feeding conditions, the
knife blocks must travel evenly through the same arc.
The knife blocks are factory adjusted and should never
be
changed.
~.
Each picker knife block is fixed on its arm~~ITwo
carballoy pieces are inserted in the block surface to
resist wear. The inserts are ground to specifications
for knife projection and replacement of the picker
block is required when the insert becomes worn.
