Paper mill has polymer transport belt for wet fibrous web with strengthened upper and lower surfaces

摘要

A paper mill has a belt (16) for transportation of a wet web and has a first side (30) with a web contact surface (38) and a second side (32) with a contact surface (40) to the paper making machine. Both sides incorporate a strengthening structure (34) with secondary build-up material (36). The belt (16) is no longer than approx. 14 m. The polymer build-up material is 1.2 to 2 thick and has a Shore hardness in the range 50 to 97 The belt machine-side incorporates transverse or longitudinal corrugated detents at least 50 deep.
