A drive unit is provided for selectively causing the flexible endless member to be pulled through said channel. The channel includes a pair of opposed sidewalls and a bottom wall. A plurality of hold-down devices are connected to an upper portion of the opposed sidewalls and are disposed at intervals along the sidewalls for holding the material engaging discs and the flexible endless member in the channel. The hold-down devices include a mounting bracket attached to the channel and a spring steel strap formed in a loop and connected at the ends thereof to the mounting bracket. The steel strap extends into and along the channel for resiliently pushing against the flexible endless member.
