8.3 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 arched 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 labelling 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 % corre-
spond 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 diagram) 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 ente-
red 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 stop-
ped 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 adapted to the dispensing speed.
