Moving heat plate comes in contact with surface

Hi, I have a model using the Heat Transfer module and the Deformed Geometry module. I have a heating plate at a fixed temperature and a long sheet initially at ambient temperature. Both entities are initially separated. The plate moves at a constant speed and comes in contact with the sheet. According to the geometry of my model and the trajectory of the heating plate, both entities should come in contact (they should just brush against each other).

When solving the model, even tough the plate clearly comes in contact with the sheet, it doesn't heat it.

What should I do so the plate heat the sheet as it moves along?

Thank you.

Louis-Daniel,

There is “Thermal Contact” boundary condition available in Heat Transfer module. This feature can be used to model heat transfer between parts that come in contact.
Thermal contact modeling is demonstrated in the following example from the Model Library:
