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). Downstream of the loading station (80) a taping station (60) is present and a transmission roller (62) bridging the two cores is capable of transmitting the moving rotation between the core portion and the core. A conveying station (50) a cutting station (30) and a sliding suction abutment (70) are present downstream. The apparatus has the peripheral dragging means (30) equipped with a device for transmitting a number of rotations suitable for causing said core and said core portion to rotate for a predetermined number of turns.
