What is the
Width Measuring Sensor?

Two discs with sensors are positioned at both edges of the film. On film without gussets the film passes over the front of the discs. On film with gussets the discs are positioned inside the gussets so that all four edges can be detected for calculation of the width.

There are two infrared sensors on each sensor disc one on the front and one on the back of the disc. The measurement takes place by the four sensors detecting the two front and the two rear edges of the gussets.

With gusseted film it is necessary to enter in the computer the depth of the gussets and the total nominal width in terms of mm.

It is possible to set the maximum and minimum variation tolerance, both in the gusset depth and in the total width. If these tolerances are exceeded an alarm is triggered.

Frequent questions

Yes, the system informs on the depth of the front gusset in relation to the rear gusset.

Yes, the GMS sensor is a complete system for width measurement with and without gusset. Equipped with two infra-red sensors on each side it can detect the two edges on film without and the four edges on film with gussets.

Yes. An alarm is triggered as soon as the film edges move outside the desired tolerance and when the nominal width steps outside the tolerance limits.

For all films that need precise widths. It controls the gusset depths as well as the overall width of the film. Therefore providing the perfect quality control with the provision of reports if required.

This is pretty simple, it only needs cleaning the sensor and lubricating the moving parts.

Yes. Modern extruder manufacturers integrate our sensors for automatic gusset control in the collapsing frame and in the bubble cage with IBC for automatic width control. For electronic integration a + and – signal is provided.
