Tower Raceways Maintenance
The film carriage is sliding on the plastic guides attached behind its back plate. The sec-
tion of the tower on which the plastic guides move (raceways) should be cleaned and re-
greased approximately every 600 hours of machine operation.
Note:
If the machine works in a dusty and corrosive environment, the race-
ways should be re-greased more often (at least every 100 hours).
Chain Maintenance
To clean the carriage lift and stretch chain, wipe them with an oily cloth once a quarter.
When machine is working in a dusty and damp environment, it may be necessary to repeat
the cleaning operation more often. Use the most common chain lubricants on the market.
With time, the chain will tend to stretch. The tower is equipped with automatic chain ten-
sioner and does not need any adjustment.
Note:
First chain tension inspection must be done after the first two weeks
of machine usage.
Cleaning The Stretch Rollers
The film carriage requires the most attention when cleaning. The film carriage requires
regular cleaning even if there are no product spills into the carriage area. Absolutely DO
NOT use wash down methods on the film carriage.
•
As the film goes though the rollers, a static charge develops from the film and pulls air
borne dust and contaminants into the rollers. The glue that is impregnated to the film,
called Tackifier, traps these contaminants to the rollers. Finally, the aluminum pres-
sure rollers on the threading gate press the debris into the rollers causing the rubber
rollers to glaze.
•
If the rollers become glazed, the film may slip, causing film shear, thus causing film
payout to be inconsistent or cause the film to tear regularly. This is completely normal
under continued use and occurs on every stretch wrapper made-no matter who the
manufacturer is.
•
The rubber rollers are recommended to be cleaned at every 2000 hours of running. Do
not clean the rollers more than once a month unless special circumstances demand.
This can cause the rollers to dry out. The cleaning requires only a stiff nylon bristle
brush, rubbing alcohol (only)*, and compressed air. The procedure is as follows.
