Abstract
The invention relates to a heating cable mat (1) comprising a net-shaped supporting element (2) and a heating cable (4) which is arranged on the supporting element. The surface (3) of the supporting element is adhesive, and the heating cable (4) is arranged in abutment against the supporting element (2). To further fix the heating cable (4), a second net-shaped supporting element (10) is arranged adjacent to the heating cable mat so that the heating cable (4) is located between the two supporting elements (2, 10).
Claims17
A prefabricated heating cable mat (1) comprising:
- a first supporting element (2) of a foraminous, flexible material having a self-adhesive surface (3);
- a heating cable (4) which is arranged on the first supporting element (2);
- and
- a second supporting element (9) of a foraminous, flexible, self-adhesive material having substantially smaller dimensions than the first supporting element (2) is attached to the heating cable mat (1), and the heating cable (4) is located between the two supporting elements (2, 9), wherein the first and second supporting elements are formed of a non-flammable material.
A method for manufacturing a prefabricated heating cable mat (1) which comprises a first supporting element (2) of a foraminous, flexible, self-adhesive material and a heating cable (4), comprising the steps of:
- arranging the first supporting element (2) adjacent to guide elements (15) which indicate a desired pattern for the extent of the heating cable (4);
- arranging the heating cable (4) with the aid of the guide elements (15), so that the heating cable (4) is applied to the first self-adhesive supporting element (2);
- arranging a second supporting element (9) of a foraminous, flexible, self-adhesive material adjacent to the heating cable mat (1), so that the heating cable (4) is located between the two supporting elements (2, 9), said second supporting element having substantially smaller dimensions than the first supporting element;
- and
- removing the first supporting element (2), the heating cable (4), and the second supporting element adhering thereto from the guide elements (15), wherein the first and second supporting elements are formed of a non-flammable material.
