UNNEL

The heat tunnel is used to shrink bands onto product after they have been placed and is
situated immediately adjacent to the sleeving machine.

The frame work of the heat tunnel is fixed on two parallel rods allowing to adjust the heat
tunnel vertically to the desired height. The tunnel can be adjusted vertically to suit the
product size, sleeve/band position and width, and it is also capable of heat control according
to the need of the sleeve/band to shrink perfectly.

ROCEDURE
To set the machine prior to normal operation follow the procedure set out below:
1. Connect main power input and pneumatic supply line (if used) and switch machine on.
2. If product is provided pitched then align input conveyor guide rails such that product is
central to conveyor belt.
3. If pitching scroll is supplied with machine, set the front guide rail to control the product
centrally and adjust the scroll laterally such that the root just contacts the product. Maintain
1mm clearance on the front guide rail. Set the height of the scroll such that its centre line lies
just below the estimated centre of gravity of the product. Balance the production its side to
estimate centre of gravity.
4. Load a full spool of material and thread to the drive roller follow the procedure in Section 3.2
steps 1 to 7.
5. Engage support roller, feeding driver roller and applicating driver roller to make sure the
mandrel is properly supported.
6. Place product on the static conveyor beneath the applicating driver. There should be enough
clearance between the end of the fixture and the top of the product for the product to be
applied properly. Adjust the clearance with the handwheel situated on top of the framework.
7. Adjust the conveyor guide rails to leave 1 to 2 mm overall clearance between the product and
the rails with the product placed centrally under the mandrel supported by applicating driver.
8. Adjust the brushes such that the correct amount of clearance between the plate and the top
of the product is achieved. The clearance is the amount the sleeve will overlap the product
top when shrunk in position.
9. Ensure product optic is positioned to detect a product as it passes the band application
position. See Section 2.6 for full optical sensing options and set up procedures.
10. Press scroll on to initiate scroll rotation, or set the scroll speed by pressing the manual adjust
2 to set up the speed you need.
11. Switch conveyor on and adjust speed to match scroll output rate.
12. Pass two products through system to test if it is pitched correctly.
13. The machine will cycle and leave one sleeve retained on a fixture and one sleeve retained in
the holding bars.
14. Remove the sleeves and check them for length (check the sleeve cut position on pre-printed
sleeves). If the sleeve lengths are incorrect adjust the “Printed Band” set at “Parameter Set
