SPIROR HP - DR
Phase 2
‒ Once the "reinforcing revolutions" count
has been completed, the conveyor
restarts and the product is wrapped
longitudinally.
‒ The product moves forward and engages
photocell (B2), the outfeed pressure
platen lowers on the product while the
machine continues to wrap product.
Note
The overlapping of film wraps is defined
by roller conveyor speed, thrust bearing
speed and film width.
Phase 3
‒ The "central bands" timer starts
counting; at count completed, the
conveyor stops, the rotating ring starts
and counts the "reinforcing revolutions"
set; the product is wrapped for the
number of reinforcing revolutions set.
Note
The number of central bands is
determined by the "Central bands" timer,
the speed of the carriers and the length
of the product.
