According to RPM, the Acu-Pulse blade is the only adjustable pulse generating forming element of its kind offered to the paper industry. Its design allows for on-the-run adjustment which enables the papermaker to optimize from grade to grade without having to change blades, it says. Meanwhile, the Acu-Step blade allows for on-the-run accurate vertical adjustment of the blades surface to the elevation of the forming fabric, it notes.

“The acquisition of RPM’s innovative and value-driven drainage products and services makes Coldwater’s industry leading drainage product line even stronger,” said David Withers, Coldwater president. “We are very excited to bring the people, products, and services of Coldwater and RPM together and we look forward to continuing our tradition and commitment of providing the most reliable innovations and services to the global paper industry.”

The parties say all RPM operations will be transitioned to Coldwater facilities in either Appleton, Wisc., or Atlanta, Ga.


Headquartered in Atlanta, Coldwater is a provider of paper machine consumables and engineered products that strive to optimize paper machine performance and reliability.
