A tube conveyor including a tube and a conveyor belt. The tube has a bore extending therethrough. The conveyor belt is movable through the tube bore. The conveyor belt includes a base and at least one first longitudinal cog. The base has a first edge and a surface. The at least one first longitudinal cog extends from the base surface. The at least one first longitudinal cog is oriented substantially parallel to the first edge.

Tube conveyor with belting having longitudinal cogs

A belting connection for attaching a first end and a second end of belting. The belting has a thickness. The belting connection mechanism includes a first stepped region, a second stepped region and a first fastener. The first stepped region is proximate the first end. The first stepped region has a first aperture formed therein. The first stepped region has a first thickness. The second stepped region is proximate the second end. The second stepped region has a second aperture formed therein. The second stepped region has a second thickness. The first fastener extends through the first aperture and the second aperture to attach the first end to the second end. The first stepped region at least partially overlaps the second stepped region when the first end is attached to the second end. When the first end is attached to the second end, the first stepped region and the second stepped region have a combined thickness that is no greater than the thickness of the belting.

Belting connection mechanism

Belting for use in a conveyor. The belting includes a fabric base and an environmentally friendly rubber composition. The environmentally friendly rubber composition is applied to at least one surface of the fabric base. The environmentally friendly rubber composition includes a rubber component, a filler, a processing oil and a vulcanizing agent. The filler is provided at a concentration of between about 50 and 150 parts per hundred weight of the rubber component. The processing oil is substantially devoid of aromatic oil. The processing oil is provided at a concentration of between about 20 and 60 parts per hundred weight of the rubber component. The vulcanizing agent is provided at a concentration of between about 1 and 10 parts per hundred weight of the rubber component.
