Abstract: A carpet seam tape apparatus for dispensing carpet seam tape below and centered with respect to juxtaposed edges of adjacent carpet sections. The carpet seam apparatus generally comprises a base guide means connected to the base adapted for mounting between upturned juxtaposed edges of adjacent carpet sections and clamping means connected to the base adapted to engage and align the carpet seam tape substantially centered between the juxtaposed edges of the adjacent carpet sections. The guide means are configured to maintain displacement of the juxtaposed edges of adjacent carpet sections when disposed therebetween at substantially less than the width of the carpet seam tape thereby effectively preserving the carpet fibers near the juxtaposed edges.
