TREND MAKINA TRN30
Automatic sheet folding and stacking machine, up to 3,800 mm wide
Brand: TREND MAKINA
The TRN series is an automatic folding machine: it makes two main folds and three cross folds. It folds and stacks sheets, pillowcases, tablecloths and napkins at high speed. It runs on multiple feeder-calender-folder lines in hotels, hospitals and large laundries. Control is via touchscreen and PLC. The electronic system measures the item's size itself and calculates the number of folds — no mechanical adjustment is needed.
Features
- Folds widths up to 3,800 mm.
- Available in single, double, or four-lane models.
- Automatically selects the lane according to the item's size.
- Automatically determines the number of main and cross folds according to the item's size.
- Full bypass: passes the item through the system without folding.
- Speed is adjusted with a button: rises up to 60 m/min and adapts to the feeder's speed.
- Automatic adjustment to avoid other lanes when length or width is exceeded.
- The first cross-fold entry is extra wide, easing service on the elastic roller.
- The first cross-fold's independent drive operates only when needed.
- The START/STOP button halts the process without interrupting the fold in progress.
- Multi-position, rightward-moving fabric guide corrects lane deviations.
- All transfers use photosensors with LED indicators.
- V-belt and chain drive for heavy-duty work, 24-volt control circuit.
- Full safety guards, interlock mechanisms, and emergency stop buttons.
- Separate air pressure regulators with gauges and automatic drain, quick-disconnect air fittings.
- Three-way electrostatic discharge and three-conveyor return technology.
- Stacker: self-adjusts to the fold length, stacks a maximum of 20 pieces.
- Options (available on request): when the feeder or calender reports a signal error, the PLC detects torn or stained items and diverts them from the line.
