  • Modular noseroller assembly for a conveyor
    Patent number: 11772896
    Abstract: A modular noseroller assembly for transitioning a conveyor belt at an end of a carryway comprises a plurality of roller-mounting modules connected to a spacer element to form a noseroller assembly that can be installed in a conveyor frame. The roller-mounting modules mount freely-rotating rollers on an axle extending through the plurality of roller-mounting modules. The configuration and size of the noseroller assembly can be easily modified depending on a particular application.

  • MODULAR CONVEYOR BELT WITH DEDICATED ACCESS ASSEMBLY
    Publication number: 20230029989
    Abstract: A dedicated access assembly for a conveyor belt forms a dedicated opening and closing point for the conveyor belt. The dedicated access assembly includes a female portion having one or more open hooks and a male portion including a hinge rod extending between linking elements. The open hook disengages from and engages the hinge rod to selectively open and close the conveyor belt. A latching mechanism can selectively lock the dedicated access assembly.
