7.3.1.2 Counter knife change with clamped anvils
- Remove anvil hold down plates and the bolts on both sides of the machine. For
this purpose the counter nuts of the setscrews are to be released and the set-
screws to be screwed back. The fastening screws of the safety plates are to be
completely unscrewed and the safety plates to be removed.
- Extend anvil carrier and anvil by pressing button „extend anvil“ onto the rail placed
laterally at the machine. Please note that the anvil carrier can only be extended
when the rotor is fully stopped. If the hydraulic cylinder of the anvil carrier is
jammed (e.g. if resin residues are sticking to the anvil), the ball valve inside the
penstock (pressure pipe) towards the anvil is to be shortly opened. This effects
that oil is being pumped under the anvil carrier loosening it from the anvil. During
operation this ball valve
must always
be closed.
- Loosen tension wedge by means of the masked tension/pressure bolts. Introduce
ISK key into cover plates at the backside of the carrier.
- Screw back set screws for anvil.
Introduce ISK-key into the rear side of the carrier.
- Remove anvil by pulling it laterally out of the carrier. Do
not
remove the stops.
- Insert new or reground anvil and tighten the set screws lightly. It is imperative that
the clamping surfaces are absolutely clean.
- Tighten wedge by means of the push/pull screw (For required torque see “Techni-
cal data“).
- Move anvil carrier laterally into the machine by activating the button „Anvil in“.
- Remount holding plates by tightening set screws against plates (for required
torque see technical data) prior to tightening the bolts securing the holding plates.
Set screws must be secured with locknuts.
