A deduster is comprised of two sets (pairs) of counter-rotating dedusting brushes in cooperation with a vacuum system for saw dust removal from wooden lumber. In addition to these features, the deduster may feature a separate, movable, top brush assembly that can be easily adjusted for different board thicknesses and raised up to allow for clearing board jams and for pass-through if boards were to be run without dedusting. This deduster apparatus is modular, thereby allowing it to be positioned over an existing machine or a lumber board unscrambler machine such as a lugged unscrambler machine. There is also a deduster for a board handling hopper.

A robotic service device for a robotic picking system grid. The robotic service device can be configured for driving to any location on the grid in order to restart malfunctioning robotic load handling devices or to perform maintenance operations or cleaning in situ. Additionally, the service device may be used to rescue robotic load handling devices operational in the picking system. The robotic service device can include a releasable docking mechanism to enable it to dock and latch on to malfunctioning load handling devices. The service device can also be provided with a cleaning device and camera device to enable a condition of a grid and other robotic devices to be monitored.

The disclosed invention utilizes deformable gaskets configured to form a seal which slides through the grooves and across the tops of escalator and travelator treads and using evacuation cleaning components as either a complete escalator and travelator tread cleaning machine or an accessory device configured to operate with an existing vacuum carpet evacuation apparatus. The disclosed gaskets in combination with evacuation and spray nozzle manifolds connected by escalator and travelator groove passages form a basic embodiment of the disclosed tread engagement assembly. In certain embodiments, the disclosed apparatus utilizes certain components of carpet evacuation equipment in combination with the disclosed v for cleaning escalator and travelator treads, including both the risers and treads of the escalator and travelator.

The output conveyor belt of a crosslapper for holding and conveying layers of card web laid to form a nonwoven is configured as an endless slatted belt with a plurality of transverse slats. The transverse slats comprise support surfaces for the nonwoven, which are formed by fibers or bristles projecting from the transverse slats.

A conveyor-rail cleaner for cleansing, scrubbing, and rinsing the rails of a cleanable conveyor system. The cleaner includes cleaning units pivotably connected to allow it to negotiate turns in the track. Position-adjustable scrub brushes accommodate transitions between one-rail conveyor segments and two-rail segments at switch segments between separate adjacent conveyor tracks. The conveyor system includes a filling station for filling the cleaning units with cleansing and rinsing agents and recharging batteries powering scrub-brush motors.
