HIGH PERFORMANCE FELT HOOD SEAL FOR THE 380SF SINGLEFACER

This upgrade offers an economical alternative to the
replacement of the costly anodized aluminum or steel
hood seal roll used in the 380SF Singlefacer.
Both the steel and the aluminum designs have their
shortcomings as used in these machines. The steel roll is
prone to warping due to contact with the hot pressure
roll, and the aluminum roll is prone to journal failure.
The cost of replacement of the seal roll and the brass
sealing bar underneath it is well over $9,000. This roll
may have to be replaced many times during the life of the
singlefacer. The seal roll rotates at a very high speed in a
bad environment, and this is the reason for its frequent
failure.
