15-5. REPAIR AND MAINTENANCE-Continued
Quality control. Adjust heating, pressing and cooling times as required for the Iron being used. Check the
quality of the adhesive bond periodically and adjust heating times and temperatures.
Check test. Periodically during the work and when adjusting the iron test a patch
which has cooled for about 5 minutes by picking with the fingers at the edge of the
patch until a tab about 1/4 to 1/2 inch (0.635 to 1.27 cm) long is formed. Pull hard
on the tab with fingers. A well bonded tab will be difficult to peel off and will
Indicate that iron adjustment and heating time are adequate. Replace the check
test patch with a new patch.
If the adhesive strikes through the patch cloth, too much heat has been applied Reduce time of
pressing or temperature of the Iron. A small amount of strike through is not objectionable provided the
patch meets the check test.
A bonded patch which has a lifted edge will be re-ironed. A bonded patch which has been subjected to
the check test will be replaced.

other details shall be in accordance with the press manufacturer's Instructions.
