Abstract:
1. A method of securing a stretchable piece of web material to a target web comprising: providing a first infeeding web of stretchable material; severing a discrete piece of said web of stretchable material from said infeeding web on a first drum rotating at a first tangential speed; setting said discrete piece of said web of stretchable material to a product pitch; stretching said discrete piece of said web of stretchable material a predetermined amount by transferring a leading edge of said discrete piece to a second drum rotating at a second tangential speed, faster than said first tangential speed, while a trailing edge of said discrete piece is carried by said first drum, to re-pitch said discrete piece of said stretchable material, to create a stretched discrete piece of said web of stretchable material; releasing said trailing edge of said stretched discrete piece of said web of stretchable material from said first drum to be carried by said second drum when a predetermined elongation percentage is achieved; transferring and stretching said stretched discrete piece of said web of stretchable material from said second drum to a third applicator drum operating at a third tangential speed, faster than said second tangential speed, to set a stretch percentage of said stretchable material; coupling said stretched discrete piece of said web of stretchable material to a target web.
