And its device.

In general, electric plates, electric mats and mats (hereinafter referred to as "electric mats") use linings made of cotton or non-woven fabrics inside the outer shell, and heat-sealed at both sides so that heating wires are arranged at regular intervals between the cotton or non-woven fabrics. Alternatively, the heating wire was fixed to the nonwoven fabric by adhesive, or the heating wire was floated in a sewing form to fix the heating wire by hand to produce an electric mat.

However, in order to arrange and fix such heating wires, the heating wires have to be fixed at both sides after a separate fixing operation, and thus the work is very difficult, and even if the heating wires are fixed, the arrangement state is easily displaced.

In addition, the method of fixing the heating wire by floating the heating wire in the sewing form has a problem that it takes a lot of time to work on a piece because it has to be floating in the sewing form by hand one by one.

Therefore, in order to solve this problem, Patent Publication No. 1994-397, "Method and apparatus for installing a heating wire" has been proposed.
