Method of preparing closure components suitable for use in diapers
Abstract:
A method of preparing closure components and a method of preparing a stable roll of such components. The methods include (a) providing a fastening portion comprising fastening means; (b) providing a continuous web of a material in a machine direction, said web having a first outer major surface and a second inner major surface and a left and right longitudinal edge at least one of said first and second major surfaces being capable of releasably engaging with the fastening means; (c) joining said fastening portion in the machine direction to the inner and/or outer major surfaces of the web so that the fastening means of said fastening portion are exposed; applying at least two first cuts to the web in order to provide at least two flaps each having a top edge and a baseline, each of said at least two first cuts being discontinuous in the machine direction and in a cross direction, each of said at least two flaps bearing at least part of said fastening portions and being connected to the web at least through its respective baseline so that the baselines of said at least two flaps face opposite longitudinal edges of the web; (e) folding over the flaps into a direction from their top edges to their baseline essentially along said base line onto the web so that the fastening means releasably engage with the first outer major surface or the second inner major surface of the web. A closure component and a stable roll made according to the methods are also disclosed.
