Abstract: Cam belt, particularly for agricultural machinery, produced from a polymer provided with reinforcement inserts, has cams on the inner side of the cam belt that are used to drive cam belt. A first flank faces in the running direction of cam belt and a second flank faces in opposite direction. Cams are spaced apart from one another by gaps in a predefined division, and gaps are delimited by first flank and second flank of two adjoining cams and a base which connects two flanks. During operation of cam belt carrier of a cam wheel resting against second flank of one of adjoining cams and against the base of a gap engage with the gaps. On outer side of belt, functional elements are fixed by a fastener which from inner side of the belt passes through the cam belt and the functional elements via at least one through hole.

Abstract: A support roller or drive roller for a drive belt of a conveyor, having a hub which is supported by use of ball bearings and which is provided with an elastic polymer layer on its outer periphery as a running surface for the drive belt. The roller is easily manufactured as the hub is made up of a hollow cylindrical outer hub which bears the polymer layer, and a hollow cylindrical inner hub which accommodates the ball bearings. Further, the inner hub is pushed into the outer hub and joined to the outer hub in a rotationally fixed manner.

Abstract: The present disclosure relates to a method for determining a respective stem volume for each respective stem of an audio composition including a plurality of stems. A first value for each of one or more parameters is received for a first segment of the audio composition. For each respective stem of the audio composition, a first respective stem volume is determined for the first segment of the audio composition based on the one or more parameters and a volume control layer.

Abstract: An inclined conveyor for a combine harvester has two drive elements which define a conveying direction and revolve in a conveying duct. Conveying duct is divided into an overshot return duct and an undershot conveying duct by a separating element situated between the upper run and the lower run of the drive element. Drive element is interconnected by carriers situated transversely with respect to conveying direction that convey harvested crop in undershot conveying duct. The difference in speed between the carrier bars and harvested crop stream is eliminated, and at least reduced, by additional acceleration of harvested crop stream. Carrier bars serve as carriers, and as acceleration elements for the harvested crop. That is because the cross section of each of the carrier bars viewed in conveying direction, occupies at least 30% of the smallest internal cross section of undershot conveying duct.

Abstract: Sugarcane harvesting machine has an inclined conveyor which conveys sugarcane sections from the harvesting machine into a collection car and has at least two traction mechanisms which extend parallel to one another and have continuous carriers, and which circulate over upper drive wheels, and lower deflection wheels carried along and situated in the feed area of the sugarcane sections.

Endless belt provides a conveyor belt of this type which has high static and dynamic strength at the connecting point, combined with great bending flexibility. This is achieved in that at least one fabric ply of each belt end, folded back on itself, wraps around a thickened area and extends between the thickened area and a stop, which forms an abutment with respect to the thickened area, in such a way that the fabric ply is jammed between the thickened area and the stop when tension acts on the belt in the reverse direction.

Abstract: An inclined conveyor for a combine harvester has at least two endless traction elements (drive elements) which extend in parallel to one another and which are interconnected by carrier bars. The carrier bars are situated transversely with respect to the conveying direction. The inclined conveyor is configured so that the load on the drive element is reduced due to the low weight of the carrier bars and a lower conveying speed. The carrier bars on the conveyor have at least two rods situated one on top of the other, have a circular cross section, and are fastened to the drive element as individual rods.
