Bags feeding
a) Manual (Standard): The bags are manually placed in front of locating indexes for feeding into the machine. For a good print registration, the bags are transferred on a conveyor belt between the colors.
b) Stream Feeder – Authomatic (Optional): The operator places bags into the automatic stream feeder, which holds up to 200 bags. A set of suction pads then picks up each bag and places it onto a conveyor belt. Once in position, the front fingers retract, and the nip rollers pull the sheet into the machine. The stream feeder operates in sync with the machine's speed.
Impression
- Print registration to the bag edge is done by front fingers and lateral guide
- The bag is carried out through the printing units on a flat belt.
- The printing units are guarded with transparent covers electrically controlled. Opening while the machine is in operation, will automatically stop it.
- The printing is done by standard flexo plates.
- Each flexo printing unit is equipped in standard with an inking and a wiper cylinder Anilox.
- The machine can be used with water or alcohol inks.
Outfeed
a) Sliding table (Standard): After printed, the bags are collected on a sliding table.
b) Rotating plates (Optional): After printed, the bags are collected on 4 rotating plates. The time given by a complete rotation is sufficient for the ink to dry (suggested for conditions of drying difficulties).
