Patent ID: 7503519

Claim:
An apparatus for attaching a fiber web tail to a winding core, the apparatus comprising: a winder drum having a cylindrical surface and an axis of rotation, wherein the direction in which the axis extends defines a cross machine direction; a winding core having a cylindrical surface of a selected length and a selected winding core radius, the winding core radius defining a winding core curvature, wherein the winding core is positioned so that the winding core cylindrical surface forms a first cross machine direction extending nip with the cylindrical surface of the winder drum; a cross machine direction extending scraping and pressing structure, the structure having portions forming a concave cross-machine-direction-extending surface thereon, the concave surface opening toward the winding core, and having a substantially similar curvature as the curvature of the winding core; a cross-machine-direction-extending scraping edge forming part of the scraping and pressing structure; and wherein the scraping and pressing structure is mounted for movement with respect to the winder drum, so that the scraping edge moves along the cylindrical surface of the winder drum, towards the winding core, to bring the concave surface into engagement with the cylindrical surface of the winding core.
