Roughening and Scouring Machine – PR 1140 Series

The PR 1140 Series Roughening and Scouring Machine is a critical finishing solution used in footwear manufacturing to prepare lasted uppers for adhesive bonding. By removing surface finishes, contaminants, and smooth layers from the bonding area, the machine creates an ideal surface for adhesive penetration, resulting in stronger and more durable sole attachment.

Featuring emery wheels for roughening, wire brushes for scouring, integrated dust collection, and optional Variable Frequency Drive (VFD) speed control, the PR 1140 Series offers flexibility, precision, and consistent performance. Available in standard and heavy-duty configurations, it helps manufacturers improve bonding quality, reduce rejection rates, and increase production efficiency.
