ABSTRACT:
To form and hold a loose starting flap (5) of a replacement paper roll (1) in which the replacement paper roll has a starting portion which is adhered to an underlying layer of the roll, with a simple easily made and reliable apparatus, the uppermost layer of the roll is perforated by a perforating wheel (8) or an intermittently operated laser (1008) inwardly of the end edge of the starting portion along a perforation line (3) which extends essentially parallel to the axis of the roll to form a flap portion. A temporary or permanently adhering element, such as a suction roll (912), a suction bar, an adhesively coated strip or bar (812) or a roller (912) with an adhesive surface (9, 909, 912) is moved with respect to the flap portion close to the perforation line (3). The adhering element is then moved relative to the roll, either away from the circumference, radially or otherwise, or the roll is rotated, for example in clockwise direction, so that the uppermost layer will tear at the perforation line and form a flap (5), which will be retained, by adhesion, against the adhering element.
