Method and apparatus for producing wrapped bales

摘要

An apparatus for producing wrapped bales comprises a wrapping device for circulating a web dispensing device in a first plane of rotation around a bale during a first wrapping stage. The surface of the web of wrapping material is kept substantially normal to the first plane of rotation. During a second wrapping stage, the bale may further be rotated by a rotating device in a second plane of rotation substantially normal to the first plane of rotation. Between the first and the second stages, the surface of the wrapping material web may be turned about 90° such that the surface of the web is always substantially normal to the planes of rotation in both stages. The first wrapping stage includes using a tunnel device, which makes it possible to produce both unbound wrapped bales and bound wrapped bales.

1. A method for wrapping bales, the method comprising:
a first wrapping stage comprising:
receiving a bale from a tunnel means, wherein the tunnel means has a proximal end and a distal end, and the distal end is an open downstream end;moving a frame means, which is movable in relation to the tunnel means, in relation to the tunnel means in a forward direction that points from the proximal end toward the distal end;rotating a wrapping material dispenser means around the bale in a circular path in a first plane of rotation, whereby a web of wrapping material emerges from the wrapping material dispenser means such that a surface of the web of wrapping material is substantially normal to the first plane of rotation;wrapping by a wrapping means the web of wrapping material onto the frame means to form a tunnel construction comprising the web of wrapping material;arranging the tunnel construction in relation to the open downstream end of the tunnel means so that the open downstream end is situated inside the tunnel construction;receiving the bale out of the open downstream end of the tunnel means and at least partly into the tunnel construction to attach the tunnel construction to the bale; anddetaching the frame means from the tunnel construction by moving the frame means in relation to the tunnel means in a backward direction that points from the distal end toward the proximal end while the bale moves out of the open downstream end of the tunnel means into the tunnel construction.
