- Ideal for Thermocouples
There are many different types of machines that use heat rollers for various industrial processes. Some examples include:
Laminating machines that use heat and pressure provided by a heated roller to continuously bond dissimilar sheet materials, sometimes with the aid of heat sensitive adhesives.
Tea bag machines that use a heated crimping roller to crimp and seal the edges of tea bags.
Diaper machines that use a heated roller to bond/seal dissimilar materials resulting in a finished diaper.
Machines for making personal products like feminine pads that also bond/seal dissimilar materials into a finished product.
Packaging machines for wrapping or packaging food or other items, that use heated rollers for sealing, bonding, or cutting off plastic materials.
This is only a small sample of the possible applications for heated rollers.
In order to connect the electricity to power the heating elements in a rotating heated roller there needs to be some type of rotating connection to transfer the electricity. Frequently, the process needs tight temperature control of the heated roll to carry out the process correctly. This requires feedback from a temperature sensor. Most machines use an older technology of a brush type slip ring which is fraught with problems. Since a brush type slip ring is a rubbing interface there is wear to the brushes which generate particles/dust. This wear/dust causes variations in the resistance of the electrical connection and requires regular maintenance, resulting in downtime. This change in resistance can give inaccurate temperature sensing, resulting in poor control of the heated roller temperature. Brush type slip rings also have a limited life due to the wear.
