The invention relates to a press according to the preamble of the main claim.

Krelesparkasse Göppingen (BLZ 61OSOQOO) Account 474595 Postscheckkonto Stuttgart (BLZ 60010070) No. 189103-702

Such a press is, for example, already from the DE-OS 22 08 682 known, but has the design shown there a whole series of structural and functional disadvantages. The latter essentially consist in the fact that once the The shearing and the pressing process take place at the same time, which already requires a great deal of force and, on the other hand, here how also with a number of other designs on the market - the shearing always over the full knife width takes place simultaneously; there are also great driving forces behind this necessary.

It is true that attempts have already been made to alleviate the last-mentioned evil to remedy that you have an inclined, so pulling knife arrangement has met, however, unilateral transverse forces of uneven magnitude occur in such a design Manhole side walls and in the ram guides.

It is therefore a partial object of the present invention to provide a To train press of the type mentioned in such a way that only relatively low driving forces are required for the cutting and the pressing process and these forces are also as centered as possible the bearings of the ram and in the press itself are distributed,

Another sub-task is, viewed as a whole, one to create a continuously working press that is structurally rela-

tively small dimensions, large amounts of waste in a simple and reliable Art can handle, while praised in the acquisition and is therefore ideally suited for recycling.

This problem is solved convincingly by the Claims specified structural and functional features, ujobei with regard to the storage bzu, - guidance of the press ram of the features of DE-GM 76 10 509 assumed uird.

In the drawings, an embodiment of the invention is schematically and explained in detail on the basis of this.

Show it:

Fig. 2 is also a side view uie Fig. 1, however partly in longitudinal section,

FIG. 3 is a plan view of FIG. 2,

Fig. H as a detail in side view of the lower belt leadthroughs of the press shaft and

opinion.

The technical definition of the individual position specifications of these Drawings are reproduced in the list of reference numbers; the The basic structure of the embodiment shown is known in principle,

Special features according to the invention are:

a.) The cutting process takes place before the Preßvargsng, i.e. only after the shearing has ended and the HdI = ^ n, ben 2 passes through the aforementioned buffer zone b, finds one

Pre-compression of the materials from the filling chamber, so = like pressing them into the conical pre-shaft 3 instead; the conicity of the latter and the largest of its counterparts » pressure, are set using the handwheels 6.

In addition, the shearing takes place, due to the arrow and

Serrated shape of the knives 8a, 8b with k not simultaneously over the full width of the shaft, but gradually from the knife center 8b to the side knives 8a _o rings drive = 2Q forces and uniform loads on all machine parts

are effected thereby.

b.) The feeding of the belts 11, 12 from below and above into the Compensating band brakes at the respective stations 13 and 1i »save the press room. The belt 12 entering at the bottom is

each through the pair of guide rollers 17, 18 laterally centered, sd it with the known hooks through the peg grooves 10, the knife recesses 9 'and the openings 19 through from below to tie the finished bale can be pulled up and at the same time remains centered, ready for a new knot 15. In addition, the tab-like notches 19a of the press shaft bottom 3 cause the incoming belts to move downward can evade and thus are not pushed together like an accordion during the pressing stroke.

c.) The machine control is ultimately designed in such a way that the light barrier 26, 26a is delayed in a manner known per se works, i.e. only switches on the press stroke when the material reaches the feed hopper

and the light barrier interrupts for a long time. The piston also remains in its foremost pressing position Stand approx. 2-3 seconds per stroke so that the material is correct is "squeezed out". In continuous operation takes place In addition, machine shutdown with optical and /

or acoustic ball-finished display whenever the forward motion by the ball rotating with the wheel 23 and the latching 2h thereon comes into contact with the limit switch.
