Broke spots

1. Most often due to inadequate pulping of broke:
— check plates and rotor of “thru-rotor” pulpers for wear and clearance
— pulpers not properly checked before dumping.
— ensure proper operation of deflakers.
— increase refining if stock will permit.
— if stock will not permit more refining, then investigate for possible alternate grade to run out the system.
2. Watch broke boxes and exercise extreme care that no wrappers or other foreign matter gets into system.
3. Increase broke refining or deflaking and raise temperature in broke system.
4. Avoid use of over-dried or super-compressed lap pulp.
— investigate more selective use of pulps as these produce the same effect as broke.
