Breast roller is a rotating roller at the side of the long net near the slurry box.
It is driven by the net, and must have enough stiffness, under the tension of the net without bending.Roll body commonly used seamless steel tube or steel plate rolled,
the surface coated with adhesive, thickness, hardness depending on the specific situation.
The breast roller must be equipped with a spatula so that the pulp block does not follow the roller and is clamped between the roller and the net.Usually, the breastroller is the first roller on the paper machine, is the beginning of the network, one of its role is to support the forming network.

In many cases, the breastroll is also a dehydrating part of the table, the Internet pulp can be in the breastroll to remove part or most of the water.
The breast roll is a tubular roll structure with sufficient stiffness and minimum deflection to prevent the copper mesh from wrinkling.
In order to reduce the load of copper net driven breastroller, the weight of breastroller should be light.
Generally medium and small low speed paper machine breastroller is not high, large high speed paper machine breastroller is slightly high.
