6. Maintenance
Maintenance activities can be easily undertaken.
Make sure you perform regular cleaning and lubrication of the bearings.
During working process, the glue tray must remain fully filled at all times.
Adhesives must have low viscosity and be properly diluted to ensure a good film
control which will determine a better coating. Perform regular cleaning of the
stripper finger blades not to damage sheet edges.
The stripper fingers are shaped to be used in all four sides, just loosen the
screws and rotate them.
It’s important to adjust all stripper fingers at the same
height to avoid damages or unwanted marks to the sheets. For short downtime
and breaks, such as lunchtime, it
’s recommended to keep coating rollers
running to avoid sticking and to prevent the accumulation of a glue shell on the
adhesive surface.
Longer downtime and breaks require complete cleaning procedures.
6.1
– Cleaning procedures
After working process is complete, a full cleaning procedure is required as
described below.
While motor is in operation at low speed, dislodge the trays from the lateral
structure moving them forward until the coating scraper (12a) is no more
submerged in adhesive. The exceeding glue in the coating rollers drops down
into the glue tray. The bottom tray is removed from the machine. Once outside
the machine, the top glue tray is removed (using animal glue). Next, replace
only the water tray back in the machine. At this point, fill in the water tray till
coating roller (12a) is submerged again, but in water this time. Here you will
notice the coating rollers are starting the auto cleaning processes and all you
need to do is drying them with a damp cloth.
DANGER
–
Always make sure you stop the motor before performing the action
above.
The stripper fingers can be disassembled for cleaning purposes.
NOTE
–
Proper and acceptable cleaning of the coating rollers and stripper
fingers assure a longer working life of the equipment.
