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.
Phase 4
‒
The product moves forward disengaging
photocell
(B1)
, the infeed pressure
platen lifts, the “tail positioning” timer
starts.
‒
After timer count has been completed,
the outlet conveyor stops and the
"reinforcing revolutions" count is started.
The product is wrapped at the tips while
at the last turn of the rotating ring, the
gripper comes forward to hook the film.
|
Important
In case of
500
reel, the machine carries
out an additional pneumatic movement
to lock the coating inside the gripper in
the forward most position.
