Rubberized textile material for a belt ply, associated rubber mixture and belt
The rubberized textile material for a belt textile ply is provided on at least one side of a textile web with a peroxidically crosslinkable ethylene-alpha-olefin-diene terpolymer rubber mixture, preferably an EPDM mixture. In this rubberization mixture the third monomer content (diene content) of the EPDM is preferably at least 4% and the rubber mixture contains: a peroxidic crosslinker, a mineral oil having an aromatics proportion of at least 50 percent by weight and at least one reactive phenol and/or reactive phenol resin capable of binding to the double bonds of unsaturated polymers. The reactive phenol and/or phenol resin and the mineral oil are present in the rubber mixture in a content of altogether 5 to 60 phr. The rubberization has an exceptional manufacturing tack coupled with good adhesion and good dynamic properties.

Sidewall fastening system for a conveyor belt
A flexible thermoplastic conveyor belt constructed of one or more belt segments having corrugated sidewalls. The one or more segments are joined end to end at one or more joints. The ends of the sidewalls at or near the joints are fastened together by fasteners to form a continuous sidewall along the length of the belt. The fasteners are toolless fasteners requiring no tools; they can be fastened and unfastened by hand alone.

RIP DETECTION SYSTEM FOR A CONVEYOR BELT
A rip detection system for a conveyor belt comprises at least one antenna and at least one sensing system. The at least one antenna comprises one or more continuous loops formed from at least a conductive fiber material. The at least one sensing system may include a transmitter, a receiver, a controller, and a power source. The at least one sensing system is configured to sense a conductivity of the at least one antenna. Based upon the sensed conductivity of the at least one antenna, the rip detection system determines a state of the conveyor belt.
SELF-STACKING SPIRAL BELT CONVEYOR WITH SMOOTH DIAMETER REDUCTION
A spiral conveyor having a self-stacking conveyor belt positively driven on a helical path up or down a drive drum. Stacker supports at opposite sides of the belt support the tiers above. Locking structure on the outer stacker supports interlock consecutive tiers. Drive members on the drive drum have a belt entrance segment and a positive-drive segment. The positive-drive segment has ridges that engage the inner side of the belt without slip. The entrance segment provides a smooth reduction in drum diameter without drive ridges to multiple belt tiers entering the helical path.

Conveyor having at least one flexible belt and method of tensioning the at least one belt
A conveyor includes first and second support shafts and at least one belt supported between the first and second support shafts that has an upper load-carrying portion and a lower return portion. A first gear is connected to the first support shaft, a second gear is connected to the second support shaft and a drive chain or belt is supported by the first and second gears and has an upper run and a lower run. The upper run includes a tension control device for maintaining a tension on the upper run and the lower run includes an arrangement for displacing a portion of the lower run in order to rotate the first gear in a first direction and the second gear in a second direction opposite the first direction to increase a tension of the upper load carrying portion of the at least one belt. Also an associated method.
