Machine for the production of spools with a system for alignment and method

The machine (1) comprises: an unwinding section (3) of parent reels (Ba, Bb) of web material (Na, Nb); a cutting station (13), comprising a plurality of cutting members (201, 203) to divide the web material (Na, Nb) into longitudinal strips (S); a plurality of winding stations (15); in each winding station (15), a guide arm (31) to guide the longitudinal strip (S), adjustable parallel to the rotation axis (C-C) of the winding mandrel (51). The cutting station (13) comprises sensor members (213, 214) to detect the position of the cutting members (201, 203). A control unit (216) is interfaced with the sensor members (213, 214) of the cutting station (13) and the positioning actuators (27), to position the guide arms (31) parallel to the rotation axis (C-C) of the respective winding mandrel (51) as a function of the position of the corresponding cutting member (201, 203). 本发明涉及种机器(1)，其包括：卷带材料(Na、Nb)的母绕线器(Ba、Bb)的退绕部段(3)；切割工位(13)，包括多个切割构件(201、203)，以将卷带材料(Na、Nb)分成纵向条带(S)；多个卷绕工位(15)；在每个卷绕工位(15)中的用于引导纵向条带(S)的引导臂(31)，
