Carbon Steel Spreader Roll 1000mm Diameter For Paper Machine
Spreader Roll Description
The Spreader Roll is a kind of roller used to eliminate wrinkles and adhesions in the process of coil cutting and winding. The curved shaft is also called a bending roll due to the irregular curvature of the roll surface. The curved roller is mainly composed of the curved mandrel, rolling bearing assembly, rubber sleeve, end sleeve, support, and adjusting wheel. The mandrel has a certain radian and is fixed on the equipment support with support. The mandrel and the roller surface are linked by bearings so that the roller surface can rotate synchronously with the coil to complete the stretching function. The arc roller bends the shaft into the required arc shape, and the shaft is equipped with bearings at a certain distance, and the rubber sleeve is put on the bearing to form an arc-shaped roller that can rotate around the shaft.

Spreader Roll Structure
The internal structure of the spreader roller mainly includes bearings, retaining rings, extension springs and cams. Among them, the bearing is the most critical part of the curved roller, which drives the rotation of the curved roller through the bearing, thereby helping the object to pass smoothly. The retaining ring mainly serves to fix the position of the bearing and ensure the smooth rotation of the bearing. The tension spring is to relieve the impact force of the arc roller during the working process and reduces the burden on the bearing. The cam is responsible for driving the bearing to rotate and works together with the upper pinion to realize the normal operation of the arc roller.
