Semi-Auto Tensionless Bag On Roll Making Machine (manual roll change)
The Semi-Auto Tensionless Bag-on-Roll Making Machine provides a highly cost-effective solution for producing rolled bags, operating at speeds up to 120 strokes per minute. Equipped with a high-speed hot-cut system and an economical manual roll change rewinder (compatible with paper core or coreless setups), it ensures strong, tension-free sealing for a wide range of film thicknesses from 0.012mm to 0.3mm.
Designed for operational efficiency and precision, the machine features German "Sick" photocell technology for accurate print registration. Supported by versatile optional modules—such as C/N/W folding, star-seal triangle folding, automatic labeling, and Edge Position Control (EPC)—it delivers adaptable and reliable performance for businesses scaling their bag-on-roll manufacturing.
- High speed hot-cut system：Upper sealing blade & bottom heating wire makes strong and high speed sealing. Seperated upper and bottom temperature control for easy micro-adjustment.
- Synchronized Feeding and cutting speed：Inverter controlled feeding matching main machine speed for easy operation without manual adjustment.
- German "Sick" photocell registration：Reliable and accurate print registration and positioning
- LCD touch panel：Easily operable human-computer interface to access parameter changes and production monitoring
- Socket type IC circuit control：Automated control system can be easily replaced by socket plugin.
- Malfunction alarm / stop：Alarm & auto-stops for abnormal temperature / No material feed / Photocell tracking miss (3 times)
- Manual change rewinder - Economy system by manually paper core or coreless rewinder between finished roll and next roll.
Available Optional Device
-
Various hole punches - Kidney/round/notch/butterfly/others -
- Various Hole-punch shapes available in standard or customized design. Fixed on the side of machine.
-
Labelling device -
- Apply paper & glue labels at the end of bag on roll rewinding cycles.
-
Extra photocell -
- Extra servo outfeeding + photocell for another line of printed bag.
-
Rewinder EPC -
- Rewinder EPC can guide film for flat edge finished rolls for good presentation.
-
Interlock rollers (Sealing Isolation) -
- Interlock rollers synchonize and isolate film tension between sealing and outfeed to avoid sealing elongation.
-
Triangle folding device (Starseal) -
- Gussted tubic film ar efolding in half by passing triangular frame and pinch for Star-seal sealing.
-
Double Triangle Folding device -
- Double triangle frames and pinch can fold in C/N/W styles before rewinder or for bottomseal star-seal bags.
-
C/N/W folding device -
- Folding finished bags into C/N/W type folding for rewinding.
