SECTION 5 TECHNICAL
VACUUM HEAD FUNDAMENTALS
Variables Affecting Vacuum Head Performance
C = as small as possible w/o the Vacuum Head hitting the Peeler Plate (typically
1/32”).
V = Enough Vacuum Pressure to hold the Label on w/o inhibiting label advance.
O = enough to deflect label slightly downward (typically 1/32”).
P = Enough Air Pressure to force label up and onto Vacuum Head.
α = Direct Air Assist Tube so Leading edge of label remains in contact with Vacuum
Head during label advancement.
