B&C Technologies IM Series Industrial Ironer - Manual (Page 46)

7. Take the wax cloth out of the folder and let it rest and cool for a minute to make it safer to
handle.
8. Move the wax cloth back to the front of the ironer. Position the front edge to the left side of
the in-feed and feed the wax cloth again.
9. Again, make sure the wax cloth comes out of the folder evenly - it will be very hot so wear
thick fabric or leather gloves to protect your hands.
10. Take the wax cloth out of the folder and let it rest and cool for a few minutes. When cooled
store the wax cloth either on a hanger bar or folded up inside a steel drum.
4.2 Running the Ironer
Proper operation of the IM chest ironer requires intelligence and diligence. One must take time to
find the speed and temperature combinations for the type of goods and moisture retention in their
situation. Following is some common guidance:
4.2.1 Cotton Sheets
For these goods the temperature may be run as high as 410 o F on the thermal fluid units which
allows very high processing speeds depending on the weight of the sheets.
4.2.2 Poly-Cotton Blend Sheets
Because of the synthetic fiber content, these goods have lower water retention after centrifugal
extraction than equivalent cotton flat goods. Also, because the melt point of polyester fiber can be
between 340
o F – 365 o F (170 o C – 185 o C) it is bad practice to run these goods at higher temperatures.
If the fibers melt they will cause a residue which is difficult to remove.
4.2.3 Dryness
Goods should be considered ”dry enough” coming out of the ironer when they feel dry 5 minutes
after folding. This can be verified with a moisture retention test – flat goods should be dried
only to 2% to 4% residual moisture retention. The operator must also understand there will be
some inconsistency when drying goods of nonuniform fabric weight (like a mixture of old and
new poly-cotton sheets). In these cases you must set up your process (temperature and rate) to
accommodate this without damage to the goods or the ironer. Over drying the goods typically
causes static cling problems in the folder and melted polyester residue deposits in the chests.
