## Abstract

A header has a middle section disposed on a main frame, at least two side sections adjacent to the middle section, a rear panel extending perpendicularly to the main frame, a flexible finger bar extending across a width of the header and a conveyor device disposed behind the finger bar. The conveyer device is designed on the side sections as a continuous conveyor belt disposed adjacent to the middle section in order to transport crop cut by the finger bar laterally in the direction of the middle section. The side sections are formed as a plurality of supporting arms swivellably disposed on the main frame that support the finger bar. Each side section has a plurality of supporting elements for supporting the conveyor belt. Each of the supporting elements is supported in a bearing point to be displaceable in the axial direction relative to the main frame.

## Claims

### Claim 1

A header comprising
middle section disposed on a main frame;
at least two side sections disposed adjacent to the middle section;
a rear panel extending substantially perpendicularly to the main frame;
a flexible finger bar extending across a width of the header; and
at least one conveyor device disposed behind the finger bar and designed, on respective ones of the at least two side sections, as at least one continuous conveyor belt that is disposed adjacent to the middle section to transport crop cut by the finger bar laterally in the direction of the middle section;
wherein the side sections comprise a plurality of supporting arms that are swivellably disposed on the main frame and support the finger bar;
wherein each side section comprises a plurality of supporting elements for supporting the conveyor belt; and
wherein each of the supporting elements are supported in a bearing point to be displaceable in the axial direction relative to the main frame.

### Claim 2 (depends on 1)

The header according to claim 1, wherein the bearing point of a supporting element is designed as a sliding joint.

### Claim 3 (depends on 1)

The header according to claim 1, wherein each of the supporting elements comprises, on an end section thereof facing the finger bar, a contact surface for the conveyor belt.

### Claim 4 (depends on 1)

The header according to claim 1, wherein a belt guide is disposed on the supporting elements at end sections of the supporting elements facing the rear panel.

### Claim 5 (depends on 4)

The header according to claim 4, wherein the supporting elements are movable relative to the belt guide.

### Claim 6 (depends on 4)

The header according to claim 4, wherein the belt guide is penetrated by the supporting elements.

### Claim 7 (depends on 4)

The header according to claim 4, wherein the belt guide comprises at least one profiled, plate-shaped segment that extends in sections in the longitudinal direction of the supporting elements.

### Claim 8 (depends on 7)

The header according to claim 7, wherein the segment comprises a guide recess extending parallel to the main frame.

### Claim 9 (depends on 7)

The header according to claim 7, wherein the segment comprises recesses that extend parallel to the supporting elements and are disposed at a distance from one another.

### Claim 10 (depends on 9)

The header according to claim 9, wherein the recesses are disposed on both sides of the guide recess.

### Claim 11 (depends on 7)

The header according to claim 7, wherein the segment comprises a wall that extends in sections perpendicularly to a surface of the segment and parallel to the main frame.

### Claim 12 (depends on 1)

The header according to claim 1, wherein a plurality of crop-guiding elements are distributed on the finger bar, across a width of thereof and wherein the crop-guiding elements are disposed next to one another finger bar and slanted at an angle with respect to the finger bar.

### Claim 13 (depends on 12)

The header according to claim 12, wherein each crop-guiding element comprises a front edge, which lies approximately parallel to the top side of the conveyor belt and wherein a continuous sealing belt is fastened at said front edge and extends extending across a width of one of the side sections and overlaps the conveyor belt (7) at least in sections.
