Automatic HEPA Filter Paper Pre-slitting Machine With CE Certification
This production line consists of an auto paper de-coiler, pre-slitting conveyor, marker, automatic counter, and filter paper pleating machine equipped with a pre-heater and monitor. It features precise frequency-controlled slitting, infrared synchronization, computer-controlled marking, and stable high-speed pleating with upper/lower alternating blades. After marking, the filter paper is automatically pleated and pre-heated.
The machine is also suitable for folding iron wire fabric, non-woven fabrics, and multi-layer hydraulic filter materials. Customizable machine width and pleating height are available, including optional “M-type” pleating.

Main Features
1. The pre-slitting machine can accurately and freely adjust the cutting dimensions through frequency converter speed regulation and cylinder blades in different filter sizes. It is simple operated but smooth and effective. After slitting the paper, the conveyor for feeding the filter paper runs in synchronization with the marking machine by equipping the infrared monitoring system.
2. The marking machine can mark in different pleat sizes, the marking distance can be set freely by the computer screen, and accurately and accurately by automatically adjusting the blades distance.
3. The pleater uses upper and lower blades to alternately finish the folding, then different pleating heights are acquired evenly and accurately by automatically adjusting the blades distance.
4. After marking, the filter paper will be pleated and pre-heated.
5. The machine is also suitable for folding the iron wire fabric and non-woven fabric of the hydraulic filter, even the multi layers folding.
