Active
Type Air Cylinder Driven (Model 030)
This applicator is used when the label needs to be centered in the application
area and/or the application surface is irregular. It is the typically
the alternative to an air cylinder tamp. The applicator can be specified
as In-Line to the direction of product flow (feeds label to pivot side),
Reverse Flow or opposite direction of product flow (feeds label to free
side of grid), or 90 degrees to product flow (feed the label to side
of grid). A Brush-On can be specified instead of a roller. This is if
the product has a compound curve or label is to be placed inside a recessed
area.
What
factors are used to determine which type is best?
- Roll form requirements
of the label
- Required orientation
of the labeling head
- Number of label
sizes required for the applicator to handle the application surface
area. The In-Line (feeds label to pivot side) is designed for 1 size
of label feed length, Reverse Flow (feeds label to free side of grid),
or 90 degree (feed the label to side of grid) can handle multiple
sizes of label feed length but has a slower application rate.

Passive Type
Spring Loaded (Model 025/Model 026)
This applicator is designed to pre-dispense the label in front of the
product. As the product moves through the applicator, a section will
swing away, allowing the product to move through. A positive drive of
the product is required for this applicator. It is typically used when
a labeling head is being re-fitted an existing product handling system
or very large or heavy products such as 55 gallon drums. LSI offers
2 models of this applicator. The Model 025 is specified for labels up
to 8"(f) x 6 ½"(w) and uses a venturi type vacuum system. The Model
026 is specified for labels up to 12"(f) x 12"(w) and uses a hi volume
vacuum type system.
This applicator
is typically specified when one or more of the following conditions
exist:
- Application
is on a convex surface
- Need to reach
into the application area and have part of the applicator move away
- Shape of the
label (ex. "banana") requires for the label to be fully dispensed.
- Cannot match
the speed of the label to the product.
- This is usually
the case for print and apply applications.
