straps or wires that are laid around, for example made of steel, are kept in their compressed size and jporm - who the _β oolche bales are better because they can be transported with lifters due to their right-angled shape and can be easily and easily stacked in order to achieve optimal use of space « "In addition, the material costs for the bale, even if the bales are placed in a cardboard transport container, are only a fraction of the cost of a lass or a box"

In order to prepare or pack such bales, however, it is necessary to remove the wires or wires that hold the bales together. To attach straps or the like, while the bale by the ram under a certain compression is held »This process leads to a considerable increase in the required for the entire cycle of the press Time and thus forms a serious part of the economy in terms of economy

The main purpose of the invention is therefore to provide a method and a device by which bales of the type described, including tying, can be completely produced without the need for it _. to carry out the tying or tying up while the bale is still held by the ram

The invention also aims to provide a method and a device of this type in which the measure or

the degree of expansion of the compressed material is used to enable the .fall from the Take out the press without having to overcome large frictional forces, and still have the desired dimensions of the To reach bale,

Sin further purpose of the jirfinaung is to provide a method and a device which make it possible to achieve maximum production rate with a baler of the type having press ram and compression space _o

The invention is particularly suitable for packing leaf or strip tobacco in bales. According to the invention, packing is preferably carried out with a press of the type with a support on which a board or plate is arranged for tying the bale, with a movable one Structure in which a compression chamber and a loading or loading device are arranged so that the structure can be lowered to set the compression chamber in a position above the first ball plate. Then the tobacco is fed to the compression chamber and the loading device to fill _β Then a ram is pushed through the feeding device and into the compression chamber to compress the filled tobacco range to a height that is less than the height desired for the bale _o Then the ram is withdrawn and the second bale plate The ram inserted at the top of the compressed tobacco

is then finally actuated again in order to complete the pressing process of the bale _o This last pressing process is carried out according to the invention in such a way that the uabak is compressed in the direction of movement of the ram to a dimension which is less than the dimension required for jailing. The compression chamber is then moved back according to the invention and the ram is withdrawn into such a position that the bale can expand to the desired extent bale boards exerted composite unit until it is exposed outside the range of the press ram _e the bale is then picked up immediately between support guides, which preferably consist of Vfelzen, which act on the ball plates or ball boards, in order to prevent further extension, "the bale , which is therefore a has a suitable fo ria, but is now freely outside the press, is now tied according to the invention in a further step with wires or bands of steel or the like, while 4 is still held together in the guides.

With the invention, a relatively simple manner very reliable in operation and be worked economically _o The material to be processed, such as Z ₀ B ₀ sheet or strip tobacco is compressed between bale boards or bales plates in a compression chamber, where the pressing together by means of a on one of the panels or one of the

409848/0779

The all-drive devices 40 are then put into operation in order to pivot the locking part 34 back into its closed position and the ram is again driven downwards. This movement is controlled so that not only the underside 53 of the press ram comes into contact with the plate 36, but that also the compressed mass of tobacco or the like is subjected to an additional compression o This step of the pressing process is carried out in order to achieve an over-compression of the mass of tobacco or derglo as a result, a _o h _o to reduce the height of the compressed mass below that required for the finished bale. " for the typical lall of a bale, which should be 1.1 m high, this step is carried out, for example, in order to reduce the height of the compressed mass to about 0.9 m »

While the ram 22 is held in contact with the plate 86 and the compressed mass of tobacco or derglo remains under pressure between the plates 85 and 86, the drive devices 48 are operated to raise the loader 8 and assembly combination, until the lower part of the structure 25 is completely located at a distance above the ram. The ram 22 is now raised exactly to the desired bale height. At the same time, the drive device 67 is put into operation in order to move the pusher plate 72 against the compressed mass,

and the drive device 75 is put into operation in order to move the combination composed of the plate 77, frame parts 78 and rollers 80 against the press ram 22 the working steps in which the drive devices 67 and 75 are actuated are timed so that the pressure plate 72 comes into engagement with the compressed mass essentially at the time when the ram stops at the desired bale height. Due to the elasticity of the compressed mass , this has the tendency to expand as soon as the ram 22 is lifted o The upward movement of the ram is therefore carried out at such a speed that the ram is withdrawn at least as quickly as the compressed Hasse expands * Accordingly, only a relatively short time remains zer period during which the compressed bias does not press the plate 8 "6 so strongly against the surface 53 of the press ram that a large friction force occurs between the plate and the press ram surface.
