Abstract: Technical problem: a low sawing precision of tubular bodies of an apparatus comprising a transverse sawing station (30), in particular said apparatus equipped with a chip-forming saw means (35), a support (11?,11?) arranged to maintain the tubular bodies (1) in rotation during the sawing step, and also comprising a carriage means (50) for carrying the tubular body (1) along the direction of its own longitudinal axis (16) towards the sawing station (30), in particular preserving the possibility of removing chips produced during the sawing from the inside of the tubular body (1), such low sawing precision, in terms of length and smoothness of the end of the portions depending upon possible small longitudinal translation movements of the tubular body (1) along the support (11?,11?).

Abstract: An apparatus for connecting and cutting tubular cores (1) for supporting rolls of wound material comprising a loading station (80), comprising a rolling cradle consisting of two parallel and horizontal rollers (10 and 11), a star-shaped driven supplier (4), having, for example, four continuous protrusions (2) that allow to load tubular cores of different lengths. The rollers (10 and 11) of the rolling cradle are arranged along a longitudinal direction (16). The apparatus comprises a pusher (5) that acts against a rear end of the core (1), once it has been loaded on the rolling cradle (10, 11), in order to bring a front end of a loaded core in a connecting station (60) where it is present the rear end of a core portion to connect, loaded previously. The pusher (5) comprises an approaching element (9) with vertical idle rollers (7 and 8).
