– things that wrinkle
When handling flexible packaging materials, it is critical that the cup
fitting and the vacuum line have a very large bore. Flexible materials
wrinkle, causing large leak paths. The cup and the vacuum generator
must be sized to accommodate that leak rate. The bore of the fitting
must be close to a 1:2 ratio to the diameter of the cup.
Typically, handling flexible materials does not involve heavy weights.
Calculating cup holding force is not required. Choose a cup with
a very thin flexible lip to ensure the cup conforms to the wrinkled
material. Multi-bellows cups work well in these applications because
of their flexibility.
The interaction between the vacuum cup and the flexible material is
critical. Because the leakage flow rates are so high, it is necessary to
use our NCDF Series of high flow (air amplifier) vacuum generators.
With so many variables affecting performance, Norgren strongly
suggests that a sample of the material be sent to our in-house test
facility for a generator and cup recommendation.
