The present invention also relates to a water pipe system with at least one storey or rising main branch to which several ring mains are connected via separation and merge openings and a cross-section constriction provided between the separation and merge openings of the assigned ring main in the branch. The object of the present invention is to specify a connection fitting which leads to improved flow characteristics in the region of the ring main assigned to the connection fitting and to provide a water pipe system which fulfils the practical requirements in an improved manner.

Abstract: For forming a ready-to-bake, endless dough ring, a dough piece is first round kneaded in a round-kneading station and then fermented in a fermenting station. In a pressure station, flattening pressure is exerted on two sides of the dough piece for a flat round piece to produce. After a relaxation interval, an inside hole is punched into the relaxed dough piece in a punching station, with a dough ring being obtained. The individual stations of a corresponding dough treatment system are connected to each other by means of a conveyor. Then secondary fermenting of the shaped dough ring takes place, which is followed by baking of a ring article. The result is an efficient method of forming a ready-to-bake, endless dough ring. Producing the baked ring article can be completely automated.

On each side of the midplane there is provided a deflection channel, which curves rearward in an arc from a direction extending perpendicular to a forward direction of travel of the machine toward an intake channel arranged along the midplane at a rear side of the machine. A deflection conveying drum is arranged adjacent a rear side of the deflection channel to convey the crop coming from the transverse conveying through the deflection channel. An additional conveying wheel, which moves relative to, and has drivers sweeping through, the deflection channel is formed separate from the mowing and intake devices and is arranged on the same side of the midplane as the deflection conveying drum, but has an axis of rotation forward of a forward side of the deflection channel.

Abstract: An intake and plucking arrangement comprises a rotatable intake device that grasps a standing plant and directs it to a plucking gap. The plucking gap is located above parallel first and second stalk rolls that pull the stalk of the plant downwardly so that the plucking gap can separate the useful parts of the plant from the stalk. The upstream end of the first stalk roll is provided with a lower screw conveyor. A conveyor element is drivingly connected to the screw conveyor. The conveying element comprises an upper screw conveyor that is located above the lower screw conveyor. Both screw conveyors are located upstream from and above the inlet end of the plucking slot. The conveying element working in conjunction with the rotatable intake device direct standing plants into the plucking slot.

Abstract: A machine for the harvest of stalk-like plants is provided. The machine has a frame, two conveying elements supported on the frame and arranged one above the other with recesses distributed around their circumference for taking up and conveying a flow of crop that includes plant stalks. A stripper extends into the intervening space between the conveying elements in order to move the plant stalks out of the recesses. The stripper is connected to the frame by a free-standing post that extends vertically and is arranged outside the flow of the crop conveyed by the conveying elements. A point of the stripper interacts with the conveying elements located to the rear of the axis of rotation of the conveying elements relative to the forward operating direction of the machine.

Abstract: The invention relates to a harvesting apparatus (10), particularly a corn picker, comprising two drawing-in and picking units (18), each of which is provided with a picking gap (24) and a drawing-in device (26) that can be operated so as to draw plants into the picking gap (24) by means of which the infructescences can be separated from the plants. The inventive harvesting apparatus (10) further comprises a stalk chopper (32) that is disposed downstream of the drawing-in device (26), is used for comminuting the plant stalks, and is provided with a knife (36) which can be rotated about a shaft extending at least approximately in a vertical direction. The invention is characterized in that the envelope circle (38) described by the knife (40) of the stalk chopper spans at least the drawing-in devices (26) of two adjacent drawing-in and picking units (18).

Abstract: A front harvesting attachment for a self-propelled harvesting machine having a central part pivotally mounted onto an intake channel of the harvesting machine, side parts that are moveable relative to the central part between an operating position, wherein the side parts are positioned on either side of the central part, and a raised transport position. Adjusting devices move the side parts between the operation and raised transport positions. Immobilizing devices selectively prevent movement of the front harvesting attachment relative to the intake channel during transport of the harvesting attachment. The immobilizing devices are coupled to the adjusting devices such that the immobilizing devices are actuated, thereby preventing movement of the front harvesting attachment relative to the intake channel, when the adjusting devices have moved the side parts to the raised transport position.

Abstract: A stalk roll for a harvesting device for harvesting crop heads of stalk-like plants. The stalk roll is provided with a roll body having projecting drivers distributed around its periphery. The pull-in speed of the stalk rolls in a picking region where the crop heads are removed is less than in a region of the stalk rolls situated farther downstream after the crop head has been removed. The diameter of the roll body in the picking region is greater than in the region situated farther downstream. In addition, it is proposed that upstream of a picking region the stalk roll have an inlet region which cooperates with the parts of the plants beneath the crop heads, where the pull-in speed of the stalk roll is greater than in the picking region.

Abstract: A combination of a harvesting machine, a crop picking head, and a vehicle to support the crop picking head. The vehicle features a mount and at least one wheel extending down from the mount that supports the crop picking head and alleviates the weight on the front wheels of the self-propelled harvesting machine when driving on the road. The vehicle is attached to the crop picking head when driving on the road and detached from the crop picking head when harvesting a field. The crop picking head includes a support frame which supports the harvesting equipment. In the preferred design, the mount is connected such that the support forces of the vehicle pass directly to the support frame rather than load more fragile components of the crop picking head.

Abstract: A harvesting header comprising a center frame section and two outer frame sections. The outer frame sections can pivot relative to the center frame section between an operating position and a transport position. The center frame section and the outer frame sections carry collection devices for gathering crops and there is a separating point that moves automatically between an operating position and a transport position in the pivot region between the center frame section and the outer frame sections. The separating points arranged in the pivot region between the center frame section and the outer frame sections move between the operating position and the transport position in the horizontal direction perpendicular to the direction of travel and/or to pivot about the height axis.
