The present invention concerns an endless conveyor belt for a conveyor device, which conveyor belt comprises a belt body that can be transversely deformed between a flat configuration, at rest, and a tubular configuration. This belt body comprises two transition regions over its width which between them define a central belt portion, as well as two side belt portions situated between each of them and the nearby side edge. At least one thickness of the side belt portions is greater than at least one thickness of the central belt portion, forming at least one over thickness region on each of the side belt portions.

A cleaning-in-place system for use with an easily cleanable flexible belt. A sprocket is provided with a body having a first opening formed between adjacent pairs of teeth. The opening extends toward the center of the sprocket to provide access to the underside of the belt, when the belt engages with the sprocket, for application of cleaning medium.

A motorized transfer apparatus is described, comprising: a conveyor belt movable along a predetermined feeding direction and comprising a plurality of modular elements arranged in closed loop; a support structure comprising a sliding surface having a substantially cross-sectional triangular shape, so as to form in sequence: a first flat portion, which is substantially horizontal and which defines a transport plane for the objects transported by said conveyor belt, a second flat portion, which defines a descent path for the conveyor belt, and a third flat portion, which defines an ascent path for said the conveyor belt. The apparatus further comprises a motorized actuator device for the conveyor belt and a drive unit, inserted inside the support structure and arranged to transmit the motion generated by the motorized actuator device to the conveyor belt. Each modular element has a length, measured along the feeding direction, which is between 1.5% and about 6% of the overall length of the conveyor belt. The third flat portion connects the second flat portion with the first flat portion.

A split drive sprocket assembly includes: a first sprocket portion and a second sprocket portion configured to be joined along an opposing mating surface to form a cylindrical sprocket body; a series of teeth extending radially from a circumferential end of the first sprocket portion and the second sprocket portion; a first shoulder connected to the first sprocket portion and extending radially so as to extend from an axial further than the teeth extends from the axial and spaced axially apart from the teeth; a second shoulder connected to the second sprocket portion and extending radially so as to extend from the axial further than the teeth extends from the axial and spaced axially apart from the teeth. The first sprocket portion and the second sprocket portion are configured to engage a belt with the teeth and the first and second shoulder are configured to overlap with the belt while the teeth are engaged with the belt.

A conveyor device for the suspended conveyance of conveyable goods using negative pressure, comprising a continuous conveyor belt guided along a negative-pressure chamber with a rearward side facing towards the negative-pressure chamber. A contact side of the conveyor belt is provided with suction openings formed between the rearward side and the contact side of the conveyor belt. A recess extending in the longitudinal direction of the conveyor belt and limited by longitudinal edges of the conveyor belt is formed on the contact side such that a suction duct sealed by the longitudinal edges and arranged transversely to the longitudinal direction of the conveyor belt with respect to the contact side of the conveyable goods is formed between the contact side of the conveyor belt and the contact side of the conveyable goods.
