Application<\/h2>\n

REMDRUK manufactures new rubber embossing rollers for Perini Catalyst DESL and refurbishes used rollers. This rubber backing roller works against a patterned steel roller. Under pressure, the steel roller embosses the pattern into tissue paper.<\/p>\n

This is the lower roller. The upper and lower rollers have the same dimensions but different rubber hardness: upper 55 \u00b13 ShA, lower 60 \u00b13 ShA. Please specify the position when ordering.<\/p>\n

Rubber and dimensions<\/h2>\n
\n
\n

NBR 60 \u00b13 ShA<\/h3>\n

For embossing, we use rubber at 40\u201360 ShA, normally 50\u201360 ShA. Softer rubber at 40\u201345 ShA performs better with open patterns.<\/p>\n<\/div>\n

\n

Crown 0.3 mm<\/h3>\n

The roller is ground to a crowned profile. The crown compensates for deflection under load, providing even pressure across the full width.<\/p>\n<\/div>\n

\n

Minimum diameter \u00d8435 mm<\/h3>\n

The roller can be ground down to this diameter. Once it is reached, the rubber must be replaced.<\/p>\n<\/div>\n<\/div>\n

Weak or uneven embossing is not always caused by the rubber. Also check the steel roller, bearings, axis alignment and nip pressure.<\/p>\n

We dynamically balance every new and refurbished tissue roller.<\/p>\n

Refurbishment<\/h2>\n

Before refurbishment, we inspect the core, journals, bearing seats and runout. Journals can be ultrasonically tested for cracks. We remove the worn rubber, apply new rubber, grind to size and dynamically balance the roller. Damaged journals are repaired or replaced.<\/p>\n

Rubber roller refurbishment usually takes 10\u201320 working days, depending on the work required. Express service takes approximately 5 working days, subject to prior agreement on the delivery date. This applies to rubber covering only and excludes additional work such as journal repairs or balancing.<\/p>\n

We rubber-cover rollers in-house up to \u00d8600 mm and 4900 mm long. Larger rollers, up to \u00d8900 mm and 6000 mm long, are available through our manufacturing partners.<\/p>\n
