PURPOSE:To prevent a layer part from being leaked to the outside with certainty as maintaining the extent of heel mat welding strength, in the welding method of a heel mat for fixing this mat on a carpet. CONSTITUTION:A peripheral groove 13 along the external form of a heel mat 20 is formed in a carpet 10, and a peripheral edge terminal of the heel mat 20 is inserted into this peripheral groove 13 high frequency welding is carried out on this insertional part, through which any possible leakage of a layer part to be produced at time of the high frequency welding is absorbed in this peripheral groove 13. |
