A deburring apparatus includes (among other components) a frame and an elongated flat element connected to the frame. Rollers are adapted to support and rotate a vacuum belt around the apparatus. A perforation device is positioned and adapted to make perforations in the vacuum belt as the vacuum belt is rotated by the rollers. Making the perforations in the vacuum belt causes debris to remain in at least one of the perforations. The elongated flat element is positioned to contact the debris in the perforations.

Universal belted chain including a first belt, a second belt, a first rod, a first fastener and a second fastener. The first belt has a first upper surface and a first lower surface. The first lower surface has a first channel formed therein. The second belt has a second upper surface and a second lower surface. The second lower surface has a second channel formed therein. The first fastener attaches the first rod to the first upper surface by extending the first fastener through the first belt. An end of the first fastener opposite the first rod is recessed in the first channel with respect to the first lower surface. The second fastener attaches the first rod to the second upper surface by extending the second fastener through the second belt. An end of the second fastener opposite the first rod is recessed in the second channel with respect to the second lower surface.

An endless belt includes a band-shaped belt main body made of a vulcanized rubber, and a coupling part that is made of a thermoplastic resin and is provided between both end parts of the belt main body, wherein the vulcanized rubber of the both end parts of the belt main body and the thermoplastic resin of the coupling part are chemically bonded to each other.

A conveyor system may include a conveyor belt and a conveyor support structure supporting the belt which includes a support truss structure extending between ends of the conveyor support structure. The system may also include a pair of wheels and an axle assembly configured to rotatably support the wheels on the support truss structure. The axle assembly may include an elongated axle housing with opposite ends each having a said wheel of the pair of wheels rotatably mounted thereon, the axle housing having an interior, and a hub rotatably mounted on each of the ends of the axle housing with each hub having one of the wheels mounted thereon. The system may include a rotation detection assembly for detecting rotation of at least one wheel and being integrated with the axle assembly and at least partially positioned within the interior of the axle housing.

An active drive spiral conveyor belt system includes a drum configured to rotate about a drum axis, a plurality of modules, a plurality of cross-rods joining together the plurality of modules, and an infeed system. The drum can include a plurality of drive bars, each with a drive member extending therefrom, and spaced an arc length. At least some of the plurality of cross-rods or modules can include a drive end configured to engage with the drive members. The plurality of modules can be configured to be collapsible relative to each other and the plurality of cross-rods. The infeed system can be configured to collapse the spacing between adjacent drive ends prior to transiting into engagement with a cooperating drive member.

A conveyor belt sanding assembly includes a panel is comprised of a rigid material. A pair of clips is each coupled to the panel and each of the clips releasably engages a paddle of a mail sorting machine thereby mounting the panel to the paddle. A sheet of sand paper is bonded to the panel and the sheet of sand paper is positioned on an opposing surface of the panel with respect to the clips. In this way the sheet of sand paper is directed toward the conveyor belt of the mail sorting machine. The sand paper abrades the conveyor belt when the paddle is moved against the conveyor belt to enhance the capacity of the conveyor belt to frictionally engage mail that is being sorted by the mail sorting machine.
