Two discs equipped with sensors are strategically positioned at the edges of the film. When dealing with film without gussets, the film smoothly passes over the front surface of these discs. The system allows for the adjustment of maximum and minimum tolerance limits for the total width of the film.
Should the actual width of the film exceed these established tolerance limits, an alarm is triggered, alerting operators to the deviation from the desired width range. This alarm serves as a proactive warning system, enabling prompt corrective action to be taken in order to rectify any width variations and ensure adherence to the specified tolerance levels.
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.



The ACS is a width controller that’s part of a system developed by Octagon to enable automatic control of film width on extruders without IBC (Internal Bubble Cooling).
By regulating the volume of air within the bubble, the ACS system ensures consistent film width, aligning it with the predetermined nominal value.
This technology relieves operators from the manual task of width control, freeing them to focus on other critical responsibilities within the extrusion hall.
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 measured 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 film manufacturers integrate our sensors at lines with IBC for automatic width control. For electronic integration, a + and – signal is provided, to open or close the calibration basket (bubble cage) to increase or decrease the width of film.
