Abstract

A paper manufacturing suction roller has a mantle (1) whose inner space (2) is exhausted by a pump or fan, and limited on wither side by air seals. The ratio of the perforated mantle surface area and the non-perforated mantle surface area is lower in the outer marginal areas than in the mid-section. The ratio of the perforated mantle surface area to the non-perforated surface area near the seals is less tan in the roller centre section. The perforations are formed by drill action. The roller outer margins and in close proximity to the seals have fewer perforations which are of lesser diameter than the centre section.
