DESCRIPTION:
BRIEF SUMMARY
The invention relates to a method of baling shrubs and bushes, in particular rose bushes, in which a hollow is formed from wire grating in the form of a flat grating portion which at least at one of two edges remote from each other comprises protecting wire ends, the hollow is filled partially with a moisture-retaining substrate such as peat, the roots, substantially freed from soil, of the lying plant are placed on the substrate, further substrate is applied to the roots, the wire grating is formed to a tube by bending together said two edges, and said edges are fixedly connected together in that through meshes along one edge wire ends of the other edge are passed and said wire ends thereafter bent over.
The invention also relates to a machine for baling shrubs and bushes, in particular rose bushes, comprising at least one trough onto which a wire grating or netting may be placed.
German utility model 1,857,927 discloses an apparatus actuable by hand for baling shrubs and bushes in which at the upper side of a box-like container rectangular in plan view a mat of resilient material is suspended on a first rigid horizontal strip. By means of a linkage said strip is mounted on the container pivotally about an axis parallel to said strip. The mat hangs in the rest position on the first strip, forms in the container a trough of substantially semicircular cross-section, extends beyond the upper container edge remote from the first strip and has a free end to which a second rigid strip provided with a grip is secured. A wire grating or net is placed on the trough formed by the mat and some baling material poured onto said grating, the plant laid with its roots thereon, baling material again poured on and then the second strip provided with the grip and secured to the free end of the resilient mat pressed against the somewhat raised first strip secured to the linkage. As a result the bale material is given a cylindrical form and at the same time is enveloped in the wire grating under a certain pressure. Wire ends at the free end of the wire mesh are to be inserted through intermediate spaces at the opposite end thereof and by pressing the first strip bent and thereby close the cylinder formed by the wire grating or mesh.
Compared with purely manual baling of shrubs and bushes this known apparatus is advantageous; however, its handling is still rather complicated. Only with great skill, and then incompletely, is it possible to cause wire ends at one end of the wire grating to penetrate into meshes at the other end in such a manner that the wire ends can thereafter easily be bent over in hook-like manner to reliably close the cylinder formed. Mechanisation is hardly conceivable because the wire grating bends differently from case to case.
Baling of plants is carried out mainly for dispatching plants. For this purpose it is usual to join a large number of baled plants to a bunch or bundle, said plants for example being placed into a box or onto a pallet. Between bales cylindrically enclosed in the known manner hollow spaces remain which represent a very considerable loss of useful bunch volume and promote drying out of the plant bales during transport and storage.
The invention is therefore based on the problem of providing a method and a machine which make it possible to bale rose plants and other comparable shrub or bush plants in such a manner that they have a uniform cross-section, can be placed together in compact manner to form bunches and are thereby better protected against drying out and damage.
In so far as it relates to a method, the problem is solved with the features of claim 1 and in so far as it relates to a machine with the features of claim 2. Advantageous further developments are the subject of subsidiary claims.
Due to the bending of the wire grating according to the invention along exactly defined edge lines the plant bale is given a regularly polygonal, in particular quadratic, cross-section which ensures a reliable and also automatable penetration of free wire ends into opposite meshes of the w
