Linear heating element for photocopier or laser printer use has a longitudinal substrate with a groove on its active edge with a filament housed in the bottom of the groove, thus preventing damage to the filament

摘要

Linear heating element has a longitudinally aligned substrate (11') with an active surface that is opposite to a surface to be heated. A filament (12') made of a resistive material layer is deposited along the length of the substrate in a groove (14') so that a surface is still effectively heated but there is no risk of friction on the filament itself.
