Abstract
A bristle strip for rotary brushes comprising a supporting channel in which the closed ends of U-shaped bristles are clamped. The channel is provided with laterally-extending guide members mounted directly thereon that project laterally outwardly beyond its side flanges to guide the strip when it is inserted in a guide track on a rotary drum and to retain it therein.
Claims11
A bristle strip comprising an elongated continuous mat of bristles formed into a U-shape having a closed lower end and an open upper end, said mat having its lower end confined between upstanding flanges extending co-extensively with said elongated mat,
- said flanges terminating at upper edges,
- a retaining cord being clamped at a centerline within the U-shape of said elongated mat, said cord being located below the upper edges of said flanges,
- a bristle holding strip being formed of thermoplastic resin of a U-shape forming a trough between said flanges to enclose the lower end of the mat of bristles and including transversely extending guide and retaining ears,
- said flanges converging toward said mat in an upward direction away from a centerline of said elongated mat to a location above said retaining cord,
- means for securing said flanges in place to prevent spreading of said flanges which would allow said mat to pop out of said trough.
