Method for stretching and repitching an elastic member for attachment to a moving substrate, the elastic member being stretchable in at least a longitudinal direction and said elastic member in an essential non-stretched condition comprising an initial length along said longitudinal direction, the method comprising the steps of: providing the elastic member in essentially non-stretched condition to a set of repitching members (11,12,13) with an initial supply pitch, said set of repitching members (11, 12, 13) comprising at least a first repitching member and a second repitching member and optionally one or more repitching members arranged between said first and said second repitching member (11,12); receiving said elastic members arranged in non-stretched condition between said set of repitching members (11, 12, 13), whereby the distance between the first and the second repitching member (11, 12) corresponds to the initial length of the elastic member; moving at least said first and said second repitching members (11, 12) following trajectories diverging from each other, thereby stretching said elastic members arranged between the repitching members (11, 12) to an application length which is longer than the initial length and which corresponds to the length of said elastic member in elastically stretched condition, whereby said repitching members (11, 12, 13) are moved with selectively variable velocity when transferring said elastic members to selectively vary the application pitch of said elastic member in stretched condition on said substrate, the variation of the speed of said repitching members (11, 12, 13) determining the application pitch of said elastic member in stretched condition on said substrate, whereby during step 3, said set of elastic members are rotated around a common rotation axis while the elastic member is being stretched from the initial length to the application length. providing the elastic member in essentially non-stretched condition to a set of repitching members (11,12,13) with an initial supply pitch, said set of repitching members (11, 12, 13) comprising at least a first repitching member and a second repitching member and optionally one or more repitching members arranged between said first and said second repitching member (11,12); receiving said elastic members arranged in non-stretched condition between said set of repitching members (11, 12, 13), whereby the distance between the first and the second repitching member (11, 12) corresponds to the initial length of the elastic member; moving at least said first and said second repitching members (11, 12) following trajectories diverging from each other, thereby stretching said elastic members arranged between the repitching members (11, 12) to an application length which is longer than the initial length and which corresponds to the length of said elastic member in elastically stretched condition, whereby said repitching members (11, 12, 13) are moved with selectively variable velocity when transferring said elastic members to selectively vary the application pitch of said elastic member in stretched condition on said substrate, the variation of the speed of said repitching members (11, 12, 13) determining the application pitch of said elastic member in stretched condition on said substrate, whereby during step 3, said set of elastic members are rotated around a common rotation axis while the elastic member is being stretched from the initial length to the application length.
