Claim:
A conveyor system comprising: a conveying belt trained around a plurality of guide rollers for movement in an endless travel path to convey articles and materials in a travel line; a first roller mounted in an operative position on a support to bear against the conveying belt; and a roller safety support system comprising a wall assembly that confines downward movement of the first roller in the event that the first roller becomes disengaged from the operative position, the roller safety support system further comprising a frame assembly, the wall assembly mounted to the frame assembly so that an upwardly facing surface on the wall assembly bears supportingly against the first roller in the event that the first roller becomes disengaged from the operative position, the upwardly facing surface bounding a receptacle in which the first roller is confined by the wall assembly in the event the first roller disengages from the operative position, the receptacle having a variable configuration, the wall assembly comprising at least one sheet connected to the frame assembly at spaced first and second locations to be in an operative state wherein the at least one sheet extends continuously between the first and second locations around the first roller without engaging the first roller, wherein the at least one sheet comprises a non-metal material and has a plurality of openings therethrough bounded by a network of interconnecting elements that cause the sheet to be weakened so that the sheet can be readily reconfigured, the plurality of openings allowing passage of discrete foreign material separated from the conveying system.
