Pelleting machine of the aforedescribed type are known

Pelleting machine of the aforedescribed type are known. For example, in rotary pelleting machines, a rotor supporting the die table is rotated by a drive. The die plates are filled with the material to be pressed through at least one so-called feed shoe, and bottom dies and top dies guided by slideways are moved to the die plates depending on the angular position of the rotor. The top dies and bottom dies are guidedly moved past at least one press station, typically a pre-press station and a main press station. The top dies and bottom dies are essentially tangentially guided past stationarily arranged pressure rollers, so that a force can be applied to the pressed material introduced into the steel belt.

According to the pelleters,the object is further solved by a feed shoe having the features recited in claim 12 and a sealing device having the features recited in claim 13 . With the at least one element forming the contour of at least one feed opening of the feed shoe, which is releasably coupled or can be releasably coupled with the base body of the feed shoe, and/or which is connected in such a way that a force directed away from the base body operates on the at least one element, the at least one feed opening can advantageously be modified by exchanging the at least one element in a variety of ways, without flaker belt the intended sealing effect. In particular, a cross-section of the opening, for example a width and/or a length of the at least one feed opening, can be easily adjusted by exchanging the element. In addition, retaining stages or the like can be placed in the feed opening. Moreover, several elements may be arranged in the at least one feed opening side-by-side and/or sequentially. This shows that there are a number of ways to adapt the feed opening to the pressed articles to be pressed.

Additional preferred embodiments of the invention are recited as features of the dependent claims. An exemplary embodiment of the invention will now be described with reference to the appended drawings, which show in:

FIG. 2 a schematic top view of a feed shoe;

FIG. 3 a cross-sectional diagram to the feed shoe;

FIG. 4 a cross-sectional diagram through an exploded view of the feed shoe;

FIG. 5 a partial exploded view of the feed shoe;

FIG. 6 a cross-sectional diagram through the marginal region of an insert of the feed shoe;

FIG. 7 a cross-sectional diagram through a profiled ring; and

FIG. 8 a cross-sectional diagram through a feed shoe with installed sealing elements.
