## Abstract

In a method of forming bundles of brushwood, brushwood is fed to a bundle rmer of a bundling machine. The various items are oriented by the machine in a manner such that the thick ends of the items lie on the outside of a finished bundle while the thin ends extend in towards the center of the bundle, and such that the thick ends of the various items of brushwood are displaced relative to one another in the longitudinal direction of the bundle. The method is continuous, and hence a bundle is constantly formed in the bundle former. As the bundle leaves the bundle former, the bundle is bound with straps or like securing elements, and cut into lengths of the desired size.

## Claims

### Claim 1

A method of bundling items of brushwood, as small trees, shrubs and other forms of undergrowth, severed branches and tops of larger trees, and tall grasses such as sugar cane, comprising the steps of gathering said items of brushwood into a substantially cylindrical bundle of substantially uniform diameter and a length substantially exceeding the length of the longest item of brushwood present, the various items of brushwood being oriented with their thick ends located generally on the outside of said bundle and displaced relative to one another in the longitudinal direction of the bundle and with their thinner ends extending generally inwwardly of the bundle, and binding said bundle with strap-like holding elements.

### Claim 2 (depends on 1)

A method as claimed in claim 1, wherein said items of brushwood are positioned in said bundle with their thick ends located along a substantially helical path around the outside of said bundle.

### Claim 3 (depends on 1)

A method as claimed in claim 1, wherein said items of brushwood are disposed in said bundle with their thick ends located along a plurality of respective circular paths around the outside of said bundle, said circular paths being mutually spaced in the axial direction of the bundle.

### Claim 4 (depends on 1)

A method as claimed in claim 1, wherein said bundle is formed continuously in a single coherent, indefinite length and is cut into sections of a predetermined, uniform length.
