<p>A machine for the compression of a bulky mass (2), e.g. plastic-coated, shredded waste paper, so as to form a compact, elongated, well-integrated body, e.g. a fuel body for heating purposes. The machine has a driven screw arrangement arranged centrally in a conically tapering space (10) which comprises on the one hand a rear feed screw (13), partly located in the said space, and on the hand a front compression screw (18), arranged concentrically in relation to the feed screw, both the said screws being rotatable at mutually unequal speeds.</p> |
