  • Patent number: 10182528
    Abstract: A draper belt assembly may include a roller and a web. The roller may include a first groove having a first interior side surface facing in a first direction and a second groove having a second interior side surface facing in the first direction. The draper belt may include a web, and first and second elastomeric belt guides received within the first groove and the second groove, respectively. The first belt guide may have a first exterior side surface facing in a second direction opposite the first direction and axially spaced from the first interior side surface by first distance. The second belt guide may have a second exterior side surface facing in the second direction, axially spaced from the second interior side surface by second distance greater than the first distance in absence of axial loads to the draper belt.

  • Patent number: 8495855
    Abstract: A draper header has an endless belt conveyor supported on two arms that pivot with respect to the frame of the draper header. Both ends of the conveyor belt are supported on the arms such that the ends of the conveyor belt can rotate about respective generally vertical axes to thereby reduce uneven tension across the fore and aft width of the conveyor belt and reduce wear on the conveyor belt.

  • Patent number: 8438823
    Abstract: An agricultural harvesting machine including a flexible cutterbar and associated draper belts for carrying cut agricultural material to a center location. The belts are guided by a drive rollers and idler rollers. The idler roller for each belt is pivotable about an axis generally at 90 degrees to the axis of the belt and the drive roller for each belt is translatable axially to minimize diagonal stresses caused by flexing of the elongated endless belt.
