DESCRIPTION OF THE PREFERRED EMBODIMENTS

A pelletizing machine in accordance with the present invention has a rotatable matrix flaker belt which is identified with reference numeral 2. The matrix disc 2 is provided with a plurality of matrix openings uniformly distributed over its periphery. Pellets are pressed in the matrix opening 4 of the matrix disc 2. The compression is performed by upper plungers 10 and lower plungers 12 in so-called pressing stations. The pressing stations are subdivided into a pre-pressing station and a main pressing station. Each pressing station has an upper pressing roller 6 and a lower pressing roller 7 which are held on a shaft 8. The shafts 8 are vertically adjustable by a drive which is releasably mounted on a stationary machine housing 14.

As shown in FIGS. 3 and 4, the pressing roller 6 is held in a bearing block 18. The bearing block 18 is provided with a linear guide 20 which is vertically adjustable on a column 22. The column 22 is supported by a receiving flange 24 which is releasably connected with a drive housing 28 for the height adjustment of the pressing roller 6. For this purpose the drive housing 28 is provided with a rail-like guide 30. The guide 30 cooperates with a rail-like, substantially dove-tail-shaped counterguide 32 in the bottom of the receiving flange so that the receiving flange 24 together with the column 22, the linear guide 20, and the bearing block 18 and therefore the pressing roller 6 and can be completely released from the drive housing 28 in direction of the arrow 50.
