Five Schober Hot-Needle Micro-perforation Systems Available
for Online or Offline Processing of Film
Schober USA announces five VentPerf-Hot systems for the online or offline micro-perforation of film and other specialty materials such as non-wovens and wallpaper. Hot perforation systems take over where cold systems leave off and, with five systems to choose from, most any budget or application can be met. No matter if the web is narrow or wide, the perforation pattern is dense or sparse, the speed slow or fast or the hole small or large there is a system to fit the challenge. VentPerf-Hot systems are ideal for packaging applications, ventilation applications and mold control among others.

| Each of the systems are available as either stand-alone systems with integrated unwind, re-wind and web guiding or they can be integrated into a production line. |
Digital temperature displays and PID temperature controls are standard on all systems. The systems are designed to automatically engage only when the programmed roll temperature is reached and when the web is at speed.
When parameters are met the anvil roll is pneumatically raised to meet the needle roll as the thermo screen is simultaneously opened. At minimum speed or if a machine stop signal is received, the reverse process automatically occurs. However, as long as there is power to the system, the needle roll continues to turn even when the machine is at rest to insure that the roll is evenly heated. All systems may be manually operated as well.

The MICROTEX system, allows for a perforation density of up to 160 holes per square inch at an operating speed of up to 320 feet per minute. The THERMOPERF system, allows for a perforation density of up to 600 holes per square inch at an operating speed of 450 feet per minute. The larger TERMICA, STAR 1 and STAR 2 systems, allow for 600 holes per square inch at a speed of up to 650 feet per minute. |
