Method and winding device for winding webs

Apparatus for applying adhesive to a web roll being wound in a winding

A clamping head for engaging the interior cavity of a hollow tube, or core, used to wind a traveling web, such as paper produced by a papermaking machine, comprises a head shank in the shape of a truncated hexahedral pyramid having a clamping surface on each side of the hexahedron. A corresponding number of clamping pieces have contact surfaces which engage the clamping surfaces. The clamping and contact surfaces are contoured with concave, convex and straight pitches in the circumferential direction relative to the shank such that their contact is substantially linear. Expansion of the clamping pieces to engage the core is provided by a combination of pivotal and sliding movement of the contact surfaces on the clamping surfaces.

A roller (10) used as support, backing or driven roller in winding devices, such as winders for winding wound rolls of paper coming from a papermaking machine, is composed of an outer cylindrical roller element (24), on which an elastic, flexible intermediate layer (26) of elastomeric material is applied. On the intermediate layer (26), an external roller mantle (33) of thin-wall spring steel is provided that can be deformed in a plane perpendicular to the axis due to the contact pressure of the roll (2) and can be pressed against the outer perimeter of the roll (2). A broad contact region is created, which leads to a lower specific nip pressure and to a lower roll hardness. Channels (27, 28) in the intermediate layer (26) serve to increase the flexibility and cooling.
