摘要:
The present invention relates to a method for producing a rim ring for a wheel rim, in particular for a wired-on wheel rim, with the following steps: providing an outer rim profile made of hardened composite fibrous material, providing a plastic shaping element, providing at least one top layer made of composite fibrous material, inserting the plastic shaping element radially within the outer rim profile, and positioning the top layer relative to the plastic shaping element and to the outer rim profile such that at least part of the top layer extends from the plastic shaping element onto the outside of the outer rim profile. The present invention further relates to a method for fastening spokes made of composite fibrous material to a rim ring. Finally, the present invention also relates to a rim ring, a wired-on wheel rim and a bicycle with wired-on wheel rims.

摘要:
The invention concerns an agricultural sprayer with an arm comprising multiple segments, which are pivotable relative to each other, whereby the arm is pivotable out of a transport position into an operating position and/or back into a transport position, whereby the complete arm is attachable to a drawing vehicle, such as a tractor, and pivotable around a first horizontal swiveling axis, whereby at least one of the segments of the arm is pivotable around a second swiveling axis, which is in general vertically aligned in the transport position and whereby the discrete segments comprise units, which are arranged relative to each other per segment such, that a work plane through those units is in general vertically aligned in the transport position, wherein the complete arm is pivoted out of the transport position in the operating position around the first swiveling axis, such that the work plane is generally horizontally aligned. The invention concerns further a system with a tractor and such an agricultural sprayer, wherein a middle segment of the arm is positioned in the operating position on a support surface on the tractor. The invention concerns further a method for pivoting an arm comprising of a multitude of segments, whereby the arm is fully pivoted out of horizontally oriented operation position in a vertically oriented intermediate position and thereafter the discrete enlarging segments, sticking away from the middle segment (4), are pivoted in the direction of the middle section in a transport position.
