To hold the filter medium in place and protect it from wear by the scraper it is wound with wire. Figure 16 shows at Z a threaded shaft which assists in wire winding.

Wiring starts from the side of the drum and after the wire from the reel has passed through a tension clip or brake and around a groove of the threaded shaft it is secured to the side of the drum. As the latter revolves the threaded slot keeps it properly spaced and the brake insures...
