Abstract
This application relates to rollers that may be used to apply pressure onto one or more sheets of material.
Claims20
A device, comprising:
- a roller shaft;
- and
- disks arranged around the roller shaft, the disks being movable in a radial direction of the roller shaft, wherein when the disks contact a sheet of material during use of the device, the disks apply a contact pressure to the sheet that can be controlled at least one of pneumatically or hydraulically;
- and wherein the device is a roller.

A method, comprising:
- laminating one or more sheets of material using a device, the device comprising:
- a roller shaft;
- and
- disks arranged around the roller shaft, the disks being movable in a radial direction of the roller shaft, wherein when the disks contact a sheet of material during use of the device, the disks apply a contact pressure to the sheet that can be controlled at least one of pneumatically or hydraulically;
- and wherein the device is a roller.
2 more elements
A device, comprising:
- a roller shaft, the roller shaft being hollow and having a recess;
- an inner roller shaft body arranged inside the roller shaft;
- and
- disks arranged around the roller shaft, the disks being movable in a radial direction of the roller shaft, wherein when the disks contact a sheet of material during use of the device, the disks apply a contact pressure to the sheet that can be controlled at least one of pneumatically or hydraulically, wherein the hollow roller shaft and the recess of the roller shaft allow the contact pressure to be controlled via an internal pressure inside the inner roller shaft body, and wherein the device is a roller.
