Abstract

A pellet press has a hollow cylidnrical pressing mould (9) which is provided with essentially radial bores and on the inner circumferential surface of which at least one pressing roller (9a), arranged eccentrically in relation to the latter, is arranged rollably. To fasten this pressing mould (9) to a press-side mould support (10), a holding device is provided, which has at least one of the following groups of characteristics: a) that there is provided indirectly or directly in the mould support (10) on the inner rotation surface at least one essentially radially fluid-actuable fixing member, e.g. a diaphragm (43), which can be brought to bear against the outer rotation surface (44) of the mould (9); b) that the mould (9) is provided on at least one of its end surfaces with at least one undercut opening (22), and that a fixing member (23a) reaching into the opening (22) is rotatable, with a grip surface (23) projecting at an angle to a longitudinal axis, by means of an in particular fluid-actuated actuating device (25 - 32), by a predetermined angular amount, at which the grip surface (23) grips the undercut of the opening; c) that there are provided indirectly or directly on the mould support (10) and the mould (9) concentric, in particular self-locking threads (52) which engage in one another. <IMAGE>
