Funktionsweise
Tyvek (DuPont) film roll is split into 4 lanes via knife wheel; each lane is formed into a tube by individual forming collars. Pneumatic 4-lane volumetric measuring cups (driven by single servo for ganged size adjustment) dose two material types into two pairs of lanes. PID-controlled jaws (4 longitudinal + 2 horizontal) seal back-seam and ends; ultrasonic horizontal seal at 1.5 mm pitch enhances seal quality. Servo horizontal jaw indexes the bag length on-screen (no eye mark needed); independent flat-blade cutter separates packs.
