Blown Film Surface Treater

The Blown Film Surface Treater is an economical system primarily used in the cast and blown film extrusion industries. The corona treater design promotes ease of thread-up along with an industry first break away electrode design.

With standard mounting brackets and lifting eyes, installation is quick and easy. The high voltage transformer is mounted directly to the station with all high voltage connections factory wired and tested.

The easy-thread, “drop through” design enables operators to thread the web through the station in seconds.

The Blown Film Surface Treater is designed to be easily accessible and durable. The stainless steel electrodes reduce contamination and provide easy cleaning. To protect the treater rolls, a zero speed switch automatically shuts down the power supply when the web achieves low line speeds. Roll bearings are positioned outside of the ozone environment to prolong bearing life. Easy view windows allow clear unobstructed view of corona discharge. The electrodes are provided with optimal support to enhance rigidity and eliminate sagging.

With Pillar’s stainless steel segmented electrode design and removable electrode styles, users can alter the treat width or lane treat according to application.

The Blown Film Treater was designed with safety in mind:

• Safety interlocks prevent operation of power supply if access covers are removed or if station is in the thread-up position.

• Electrode area is completely covered by lightweight aluminum panels.

• Built-in exhaust flanges allow for easy connection to ozone exhaust blowers or ozone destruct systems to protect the plant environment from ozone emissions.

A few additional features of the Blown Film Surface Treater are:

• Easy roll removal through the top of the station

• Air gap adjustment

• Easy electrode pitch and gap adjust

• Zero speed switches prevent power supply from running if either roll should stop or rotate below the preset level

• Viewing panels to assess corona discharge
