SPIROR HP - DR
Phase 2
‒ When the “head and tail revolution”
count is completed, the conveyor
restarts and product length wrapping
begins.
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 product moves forward disengaging
photocell (B1), the infeed pressure
platen lifts, the “tail positioning” timer
starts.
‒ After the timer count has finished, the
outfeed carrier stops, the “head and tail
turns” counter starts; the tail of the
product is wrapped and gripper comes
out at the last turn of the rotating ring to
grasp the coating.
