Benefits of technology
[0010]The invention is partly based on using of a tunnel means which is capable of holding together the material of bales produced by a bale producing means i.e. capable of at least partly retaining the structure of bound and unbound bales produced by a bale producing means prior wrapping the bales with wrapping material.
[0011]The invention is partly based on using of a tunnel means and a wrapping means which are movable in relation to each other in such way that the wrapping means is capable of applying wrapping material web on the on the sides of an open downstream end of the tunnel means. This makes it possible apply wrapping material on the open downstream end of the tunnel means and / or on the sides of the open downstream end of the tunnel means and then to attach the wrapping material web wrapped on the open downstream end of the tunnel means and / or on the sides of the open downstream end of the tunnel means to the end of a bale when a bale starts to move through the open downstream end of the tunnel means so that for example an unbound bale does not in an uncontrolled manner expand when the unbound bale exits the tunnel means through the open downstream end.
[0013]The invention is partly based on moving the bale apart from the open downstream end of the tunnel means so that wrapping material web wrapped onto the sides of the open downstream end of the tunnel means detaches from the sides of the open downstream end of the tunnel means and follows with the bale to for example prevent an end of an unbound bale to expand in an uncontrolled manner when an unbound bale finally completely fully exits the tunnel means.
Problems solved by technology
One problem with the method and apparatus known from publication WO / 1994 / 022717 is that if the article to be wrapped is a bale, the bale must be bound to hold together the material of the bale i.e. to retain the structure of the bale prior to the wrapping.

Embodiment Construction
[0026]The figures show an example of a method and an apparatus according to the invention.
[0027]First the apparatus and preferable embodiments of the apparatus will be described.
[0028]The apparatus for producing wrapped bales 1 comprises bale producing means 2 for producing bales 3. The bale 3 can for example contain straw, fodder, cotton, branch, pulp or waste.
[0029]The apparatus comprises furthermore dispenser means 4 for dispensing a web of wrapping material 5.
[0030]The apparatus comprises furthermore wrapping means 6 for circulating said dispenser means 4 in a first plane of rotation (not marked with a reference numeral in the drawings) around said bale 3 for wrapping said web of wrapping material 5 around said bale 3 while keeping the surface of said web of wrapping material 5 substantially normal to said first plane of rotation.
[0031]The dispenser means 4 and wrapping means 6 corresponds preferably, but not necessarily, to the dispenser means 4 and wrapping means 6 presented a...

Abstract
The invention relates to a method and an apparatus for producing wrapped bales. Bales (3) is in a first wrappingstage moved past wrapping means (6) while said wrapping means (6) provided with dispenser means (4) are rotated around said bale (3) along a circular path in a first plane of rotation. In a further optional second stage of wrapping said bale (3) is rotated by rotating means in a second plane of rotation substantially normal to said first plane of rotation. Between said stages the surface of the wrapping material web is turned about 90° such that said surface of said web is always substantially normal to said planes of rotation in both stages. The first wrapping stage includes using of a tunnel means (9), which makes it possible to produce both unbound wrapped bales and bound wrapped bales.
Description
FIELD OF THE INVENTION[0001]The invention relates to a method for producing wrapped bales as defined in the preamble of independent claim 1.[0002]The invention also relates to an apparatus for producing wrapped bales as defined in the preamble of independent claim 10.[0003]Publication WO / 1994 / 022717 presents a method and an apparatus for wrapping an article with a web-like wrapping material. Said article is in one stage moved past wrapping means while said wrapping means provided with dispenser means are rotated around said article along a circular path in a first plane of rotation. In a further stage of wrapping said article is rotated by rotating means in a second plane of rotation substantially normal to said first plane of rotation. Between said stages the surface of the wrapping material web is turned about 90° such that said surface of said web is always substantially normal to said planes of rotation in both stages. One problem with the method and apparatus known from publica...
