Apparatus (1) and method for closing an open end (2) of a tubular body (3), which is conveyed lying flat by a transverse conveyor (5) in a transverse conveying direction (6) transverse to the longitudinal direction (7) of the tubular body (3). The apparatus (1) comprises an application unit (8) designed to cover the open end (2) of the tubular body (3) with a V-shaped or U-shaped folded material strip (10) and connect said material strip to the tubular body (3) in an overlapping manner, such that the material strip (10) surrounds the tubular body (3) at the open end (2) and closes the open end (2) of the tubular body (3). On both sides in the longitudinal direction (7), the tubular body (3) comprises side folds (11) having side fold walls (19) between main sections (4) of the tubular body (3). The apparatus (1) further comprises a connecting unit (9) which, in the transverse conveying direction (6), is arranged in front of the application unit (8) and, in the region of the open end (2), connects each side fold wall (19) to a main section (4) of the tubular body (3).
