A machine for on-site folding and securing a tape to an unfinished edge of a carpet. A housing rolls under the carpet. A heating unit is contained in the housing and heats the tape to melt an adhesive thereon. A die is interchangeably mounted to the housing and has the tape feed therethrough to be folded and attached to the carpet by way of the melted adhesive thereon. A first embodiment of the die has spaced-apart bottom and a top walls to receive the tape therebetween. A second embodiment of the die further has a pair of flanges extending outwardly from free edges of the bottom and top walls, respectively. The pair of flanges fold inwardly onto the bottom and top walls, respectively, and are spaced a slight distance from the bottom and top walls, respectively, so as to form a pair of guides that receive the tape.
