A bed (10) includes a frame (12) having at least one articulated frame section (22, 26, 30, 32) and a drive system (34) for moving the articulated frame section (22, 26, 30, 32).

A special hinged screen frame (42) allows the frame to assume a shape in rough approximation to the panel curvature.

For that purpose, an articulated frame (2) with joints (6) located at the edges of a trapezium which allow the articulated frame (2) to swivel in that plane serves as a mounting arrangement.

The scissors frame (11) which consisted of one side has two connected ends member.

An articulated frame is optionally provided for additional independent movement of the cells.

The wheel frame (9) is fixed on a longitudinal girder which is fixed at the frame crosstie (1) through a hinge frame (2).

Said folding frame is provided with a first subframe (4), which is arranged transversely to the working direction of the machine, and at least a second subframe (8).

The invention relates to a folding frame for a multi-sectioned field machine.

The articulating frame may also be configured to cause concave depressions similar to mechanical key caps in the surface.
