Adjusting the Profiling
The Profiling function is used, if an uneven good has to be labelled continuously. The
dispenser speed has to be varied according to a trapezoidal profile when labelling ar-
ched goods to stick on the label without folds. The Profiling can be adjusted in a broad
range to label different good shapes. The ratio between the goods speed and the label-
ling speed, the beginning and length of action can be adjusted.
First the speed factor has to be entered. This factor depends on the inclination surface
of the goods surface at the leading edge of the label. The factor is specified in percent
of camber. 100 % correspond to the goods speed, and 200 % to the double speed (
P1
in diagram below).
The beginning of the profile (
P2
in diagram) and the length of the profile (
P2 - P3
in dia-
gram) are now entered for normal speed labelling. In this case the value of labelling
speed and of the goods speed are equal.
After having passed the length of profile (
P3
), the labelling speed is increased (4) to the
speed entered with the factor (
P4
), until the trailing end of the label is detected. From
this point to predispension it is decelerated (5). If the trailing end of the label is reached
before the profile is finished it is stopped normally to predispensing.

To adjust profiling optimally, first labelling takes places normally so that the center of
the label is placed in the wanted position. Then the function is optimized for best result
by modifying the values
factor, start
and
length
. The position of the label is influenced
by the change of the dispensing speed. Therefore the position must possibly be adap-
ted to the dispensing speed.
