Poor Machine Alignment
Machine alignment is the first thing you should check when experiencing
web performance problems. If machine stands are not properly aligned,
other attempts to "fix" the problem may be a waste of
time. Though most machines are aligned when first installed, misalignment
can develop later due to vibration, improper machine or roller maintenance
or tension over time.
If machines modules are not aligned from one unit to the next,
your web could experience problems trying to correct its entry angle
from one module to the next. Poor alignment between rollers can
cause a wide variety of web problems including drift, stretching,
and wrinkling. Straightening out even the slightest misalignment
is critical to achieving high quality web operation.
Though alignment services can be costly, they may save you time
and money over other remedies that simply do not work. Checking
machine alignment is an essential starting point and a good investment.
