Abstract
A thin-walled heating system is provided which has only a minimal thickness and must be easy to dismantle. For this a textile fabric is envisaged with a heating circuit arranged therein, whereby the heating circuit (2) runs entirely inside the fabric (20), with the exception of the electrical connection end-pieces (22, 24). The surface heating textile material for heating blankets, floors of rooms and the like has a sheet of fabric, an electrical heat-producing conductor wire embedded in the sheet of fabric and extending in a series of uninterrupted undulations from its first end portion located at a first end portion of the sheet of fabric to its second end portion located at a second end portion of the sheet of fabric, a first electrical contact lead at the first end portion of the conductor wire, a second electrical contact lead at the second end portion of the conductor wire, and fabric portions between each undulation of the conductor wire allowing for unimpeded cutting of the fabric (20) without severing the conductor wire and disrupting the flow of electric current through the conductor wire from the first end portion of the conductor wire to the second end portion of the co…
