Paper roll supports (cradles)
What it is
Jumbo paper rolls (1-2 meter diameters, tons in weight) in handling between production lines and packaging areas are supported on cradles coated with PU elastomer. Prevent surface damage to the roll, offer non-slip adherence and durability under intensive use.
The PU technology applied here is typically medium-hardness cast elastomers, selected for the combination of mechanical, chemical and processing properties suitable for the application. Specific formulations vary by equipment manufacturer or final integrator, but the base system has stable characteristics documented in technical literature and segment-specific standards.
Why it matters
For the pulp and paper industry — one of Brazil's most strategic sectors, with Suzano and Klabin among global top players — paper roll supports is a decision in continuous high-pressure, high-speed operational environment. Modern paper machines operate at speeds of 1500-2000 m/min in 24/7 operation, and components must endure this regime for months between maintenance stops.
Current drivers. Brazilian pulp export drives demand for new machines and modernization of existing ones, all consuming technical components. Growth of paper packaging (replacing plastic) expands premium paper demand. Sustainability via water and energy savings in process pushes equipment redesign with more efficient components.
