20150298912 | LOW FRICTION, DIRECT DRIVE CONVEYOR BELT - A thermoplastic endless belt has a smooth outer surface substantially free of discontinuities and an inner surface with a plurality of teeth at a given belt pitch. The teeth are adapted to engage a pulley with circumferentially spaced sheaves at a pulley pitch greater than the belt pitch. The belt is slightly stretchable so that the pulley can drive the endless belt when engaging the teeth within a range of load on the belt. Means are provided to minimize friction between the belt and the drive pulley. Also, a position limiter ensures that the driven tooth stays engaged optimally with the drive sheave. | 10-22-2015 |
20110048903 | LOW FRICTION, DIRECT DRIVE CONVEYOR BELT - A thermoplastic endless belt has a smooth outer surface substantially free of discontinuities and an inner surface with a plurality of teeth at a given belt pitch. The teeth are adapted to engage a pulley with circumferentially spaced sheaves at a pulley pitch greater than the belt pitch. The belt is slightly stretchable so that the pulley can drive the endless belt when engaging the teeth within a range of load on the belt. Means are provided to minimize friction between the belt and the drive pulley. Also, a position limiter ensures that the driven tooth stays engaged optimally with the drive sheave. | 03-03-2011 |
20100147656 | CONVEYOR WITH TROUGHED LOW FRICTION, POSITIVE DRIVE BELT - A conveyor comprises an endless thermoplastic belt having a substantially flat surface on one side of the belt and a plurality of teeth on the other side of the belt. The teeth are adapted to be driven without tension around a drive sprocket and an idler. The conveyor further includes means to cause the belt to form a longitudinal trough between the drive sprocket and the idler to retain conveyed items on the belt. The means can comprise a discontinuity in the teeth, shortened teeth, and/or guides that apply a force to the edges of the belt. | 06-17-2010 |
20090301845 | THERMOPLASTIC BELT CONNECTOR WITH FINGERS - A toothed belt connector for making an endless belt has two leaves, adapted to be connected to each other by knuckles along one or more teeth. Each knuckle has at least one hole extending through tooth portions so that when the holes are in registry, a pin can be extended through the holes to connect the leaves at the teeth. The leaves can be adjoined to the ends of a belt to make the belt endless. The tip end of each knuckle can be beveled or it can have a stepped finger that fits into a cutout on the opposite leaf to keep the end of the knuckle from protruding as the belt wraps around a sprocket. | 12-10-2009 |

20090008224 | LOW FRICTION, DIRECT DRIVE CONVEYOR WITH A RAKED TOOTH DRIVE - A conveyor includes an endless belt having teeth with drive faces raked away from the direction of travel. The conveyor also includes a drive pulley having sheaves with drive faces raked toward the direction of travel. The drive faces on the sheaves engage the drive faces on the teeth to move the belt and the raked angle tends to pull the belt inwardly. A stationary foot assists removing a driven tooth from its corresponding sheave. | 01-08-2009 |
20090008025 | CONVEYOR BELT - A thermoplastic endless belt has a smooth outer surface substantially free of discontinuities and an inner surface with a plurality of teeth at a given belt pitch. The teeth are adapted to engage a sprocket with circumferentially spaced sheaves at a sprocket pitch greater than the belt pitch. The belt is slightly stretchable so that the sprocket can drive the endless belt when engaging the teeth within a range of load on the belt. The belt is preferred for use in conveyors in food processing industries where the smooth outer surface can transport food items and is easier to clean and keep free of impurities. | 01-08-2009 |
20090000920 | Curved Conveyor with Guide for Preventing Radial Belt Migration - A curved conveyor comprises a toothed, endless belt and a slider bed that supports a portion of the belt. The slider bed can include at least one guide in the form of a rail extending along the slider bed in the direction of belt travel. Each of the belt teeth are discontinuous and have at least one gap sized to receive the at least one guide; thus, the at least one guide prevents inward radial migration of the belt during movement of the belt. The conveyor can further comprise a center guide wheel or a guide post to prevent belt radial migration. | 01-01-2009 |
