Abstract: A carpet tape seam applicator for use in the installation of carpet pieces which abut to form the seam, the applicator including a pair of U-shaped bracket portions pivotally mounted together and intersecting at a substantially right angle with a removable spindle adjacent the pivot carrying a roll of carpet tape, a pair of rollers at one end to contact the floor surface where the tape is being applied, and a centrally located arm extending rearwardly from the opposite bracket portion. The arm has a laterally curved surface to conformably receive the handle of a heat bonding iron to heat the glue on the tape and activate the glue so that the carpet edges of the abutting pieces can be pressed down onto the tape as the applicator passes thereover. The central arm and handle of the heat bonding iron are easily gripped by the installer for ease of operation.
