Nip Uniformity Testing

Machine Direction
The MD tool can accurately determine the nip impulse profile and intensity of a shoe press nip. This is now an essential troubleshooting tool for the Albany International Process Belt team.

The machine direction nip impulse profile is different for each shoe press type. The illustration to the left shows the typical features of a long nip with gradual pressure build up followed by a sharp drop at the nip exit.

Cross-Machine Direction
The CD tool can be used to assess the nip pressure uniformity. An uneven nip can often lead to premature belt failure.

There are many parameters to monitor on the cross-machine profile on a shoe press nip. The adjacent chart shows the peak nip intensity along a shoe press nip. On this press, the shoe is out of alignment with the roll.

Thermal Imaging

Infrared thermal imaging has been utilized in the press section for many years. The high sensitivity and resolution of modern infrared cameras allows detection of temperature differences as small as 0.1 degree Celsius. This is particularly important in the press section where there is often very little thermal input. Nonuniform temperature across a running shoe press belt can often be related to uneven loading or belt damage.

Shut Down Inspections

	Albany International's sales and service team is available to inspect all types of process belts on a varity of different machines. We will provide an evaluation and assessment of the remaining life of the belt, any damages or wear that may have occured, and any general advice that may be helpful.
	The use of dental putty allows us to accurately measure the groove depth. Several samples along the CD of the belt allows us to form a full CD profile.
