Description
- The invention relates to a method for producing wrapped bales as defined in the preamble of
independent claim 1. - The invention also relates to an apparatus for producing wrapped bales as defined in the preamble of
independent claim 10. - 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 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. A separate bounding, which is disposed under the wrapping, more precisely between the bale and the wrapping, is after the wrapping of the bale unnecessary for holding the material of bale together, because the wrapping can perform the task of holding the material of bale together.
- The object of the invention is to provide a new and inventive method and apparatus for producing wrapped bales which is suitable for producing both wrapped bales provided with a bounding prior to the wrapping and wrapped unbound bales i.e. bales not provided with any bounding prior to the wrapping.
- The method for producing wrapped bales of the invention is characterized by the definitions of
independent claim 1. - Preferred embodiments of the method for producing wrapped bales are defined in the
dependent claims 2 to 9. - The apparatus for producing wrapped bales of the invention is correspondingly characterized by the definitions of
independent claim 10. - Preferred embodiments of the apparatus for producing wrapped bales are defined in the
dependent claims 11 to 15. - The invention also relates to the use of the method according to any of the
claims 1 to 8 or to the use of the apparatus according to any of theclaims 10 to 15 for the production of unbound wrapped bales. - 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.
- 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.
- The invention is partly based on moving the bale and the wrapping means in relation to each other while the bale exits the tunnel means through said open downstream end and on wrapping by means of said wrapping means wrapping material web on the sides of the bale while the bale moves out of said tunnel means through said open downstream and on continuing wrapping by means of said wrapping means wrapping material web on the sides of the bale as the bale fully exits the open downstream end of the tunnel means so that wrapping material web also becomes wrapped onto the sides of the open downstream end of the tunnel means.
- 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.
- After the first wrapping stage in the invention can follow a second wrapping stage, in which the bale, as in the method and the apparatus for wrapping an article with a web-like wrapping material presented in publication WO/1994/022717, is rotated a second plane of rotation, which is substantially normal to said first plane of rotation, whereby wrapping is provided onto the sides of said bale in a second direction of wrapping substantially normal to said first direction of wrapping.
- In a preferred embodiment of the method for wrapping an article with a web-like wrapping material, the method comprises, as in the method presented in publication WO/1994/022717, a first wrapping stage and a second wrapping stage and the apparatus of the invention is designed to perform a first wrapping stage and a second wrapping stage. The first wrapping stage comprises moving the bale and wrapping means in relation to each other, said wrapping means having a wrapping material dispenser means, said wrapping material dispenser means being arranged to rotate around said bale in a circular path in a first plane of rotation, whereby a wrapping material web emerges from said wrapping material dispenser means such that the surface of said wrapping material web is substantially normal to said first plane of rotation and said wrapping material web becomes wrapped on the sides of said bale in a first direction of wrapping. The second wrapping stage comprises turning said bale in a second plane of rotation, which is substantially normal to said first plane of rotation, whereby the wrapping is provided onto the sides of said bale in a second direction of wrapping substantially normal to said first direction of wrapping.
