ELECTRICAL HEATING DEVICE WITH FLAT TEXTILE CARRIER

摘要

An electrical heating device (25) has a flat heat resistor carrier (26) which has a matrix of a plurality of fibers forming a fleece and a plurality of through-holes (55), and an electrical resistor (27) which attached to the heat resistor carrier (26). At least some of the through-holes (55) in the carrier (26), are used for passing air through the carrier (26), are made by providing a local interruption within the matrix of fibers, are made by interrupting the fiber matrix in a way nondestructive for fibers, and have a base area of at least 0.5 mm 2.
