ABSTRACT:
A tape drum provides an improved method for operatively coupling a ladder tape to a tilt rod in a venetian blind headrail assembly. The tape drum includes a receiving cavity and resilient opposed retaining members for retaining the tape drum in assembled position on the tilt rod. A slot on either side of the receiving cavity holds the portions at one end of the ladder tape in position across the receiving cavity so that, upon assembly of the tape drum to the tilt rod, the end portions of the ladder tape will be compressively engaged between the retaining members and the tilt rod.
