Patent number: 8709190Abstract: In order to form stacks, of which each forms a book block, folded sheets are provided with an adhesive application or layer of adhesive before they are placed on one another. Said adhesive application is applied to the sheets adjacent to the folded edge of said sheets and extends in the direction of said folded edge which comes to lie in the spine of the book block. The adhesive can be applied as a continuous track or as a track which is interrupted multiple times, or else in a punctiform manner. The sheets are joined to one another in the stack by means of said adhesive application, with the result that they maintain their position within the stack during further transport of the stack.Type: GrantFiled: August 14, 2009Date of Patent: April 29, 2014Assignee: Hunkeler AGInventors: Franz Hunkeler, Kurt Graber

Patent number: 7650741Abstract: A windguard is adapted to be attached to the frame of a crop pickup in overlying relationship to the pickup tine rotor so as to control the incoming flow of crop materials. A transversely extending crop hold down portion of the windguard is pivotally supported between the front ends of a pair of fore-and-aft extending support arms that are pivotally attached at their rear ends to the frame of the pickup so that the windguard can articulate as it is moved up and down relative to the pickup by engagement with inflowing crop material.Type: GrantFiled: January 5, 2007Date of Patent: January 26, 2010Assignee: AGCO CorporationInventors: Kurt Graber, Ryan A.

Patent number: 7448196Abstract: A hay baler provided with a tubular duct within which charges of crop material are prepared before being stuffed into the baling chamber has a windrow pickup device at its front end to lift crop materials off the ground as the baler advances. The effective operating width of the pickup is wider than the inlet to the duct so that the stream of crop materials lifted off the ground must be converged centrally into alignment with the inlet before entering the same. A pair of lower stub augers on opposite sides of the inlet are assisted by a pair of upper stub augers rotating in opposite directions relative to the lower augers to accomplish such convergence. A windguard overlies the incoming crop flow as well as the consolidation zone between left and right sets of the stub augers so as to maintain effective control over the flow at all times.Type: GrantFiled: January 5, 2007Date of Patent: November 11, 2008Assignee: AGCO CorporationInventors: Thomas G. Schrag, Edward W. Esau, Kurt Graber, Ryan A. Zecha

Patent number: RE40604Abstract: A mower conditioner includes a rotary style cutter bed and a pair of laterally extending crop conditioning rolls spaced rearwardly from the cutter bed. Crop flow is improved in the machine by a laterally extending conveying roller located between the cutter bed and the nip defined by the conditioning rolls. In particular, the conveying outer roller serves to lift cut crop up from the cutter bed and convey the crop rearwardly to the nip. This ensures that the cut crop moves in a steady stream from the cutter bed to the conditioning rolls, and thereby reduces the risk of cut crop being thrown forwardly by the cutters. A downwardly open area is preferably defined between the conveying roller and the cutter bed to provide a space through which dirt and debris can drop out of the machine. The conveying roller preferably has a rotational axis that is lower than the rotational axis of the lower conditioning roll and generally vertically aligned with the substantially planar cutting zone defined by the cutter bed.Type: GrantFiled: January 26, 2004Date of Patent: December 16, 2008Assignee: AGCO CorporationInventors: Martin E. Pruitt, Kurt Graber, Cecil L. Case, Michael L. O'Halloran
