LABELER TYPE SETUP PROCEDURE
MERGE APPLICATOR SETUP
The merge applicator is used to apply labels to products moving on a conveyor. A label is feed onto the
surface of the product at the same speed that the product is moving.
1. On the display, under “APPLICATOR TYPE” select “MERGE” applicator. Also, indicate
whether it is in a right-hand or left-hand configuration using the “RT/LT HAND” selection.
2. Go through the general label setup procedure.
3. Position the peel edge so it’s between 1/8” and 1/2” away from the product at approximately 20
degrees to the product surface.
4. Adjust the applicator brush so that it will lightly touch the product. It should be angled so that the
label is supported as it is fed out. NOTE: The applicator brush is used to aide in the tacking
of the label to the product. It is not made to be a wipedown.
5. Label stop can be set so that the label is flagged past the peel edge but must miss the passing
product.
6. Web speed should be set to match the speed of the product.
7. Go to the product setup section of this manual to finish setup.
MERGE LABEL PROFILING
Profiling is used to aide in labeling products that have a concave or convex surface. If the surface of the
product is convex, the labeler will dispense a label at web speed during the “rise area” distance. When this
distance has been traveled, the web speed changes to (web speed) x (web ratio) during the “flat area”
distance. After traveling the combined rise plus flat distance, the labeler returns to web speed for the
remainder of the move. The reason for this action is that convex products start out farther away from the
peel edge than it will be by mid-product. The label is dispensed at normal speed at the beginning of the
product. As the product surface moves closer, the label must slow down so that the labels do not wrinkle.
As the product surface moves away, the label speeds-up.
On concave products the label is dispensed at web speed initially. As the surface of the product moves
away, the label is dispensed faster to force the label into the product. The label dispense speed is slowed as
the product surface moves closer to the peel edge.
NOTE: 1) Label profiling is a function of the merge applicator only.
2) Label profiling is enabled when the “web ratio” is set to something different than “1”.
3) Max. speed for the labeler is 1500 ”/min. for normal speed applicators or 2100 ”/min for
high speed applicators. The machine will not exceed this speed even if the web ratio is set
to a number higher than “1”.
