Abstract

In winding machine for winding running webs of material, for instance paper webs or plastic foil, contact roller systems are known which have several roller segments arranged next to each other with their frontal sides, and which are supported to rotate freely and be perpendicularly movable with respect to their rotation axis. Each roller segment is held by a frame, which is supported to move perpendicularly to the rotation axis. Each frame of a roller segment comprises two lateral support plates extending parallelly to their frontal sides, whereby the neighboring support plates of two roller segments are arranged one above the other perpendicularly to the motion direction. The support plates can have deep annular grooves wherein the frontal faces of the roller segments can rotate free of touch.

Dependent claims

A contact roller system for a winding machine having at least one winding roll on which a web is to be wound, said contact roller system comprising:

a plurality of contact roller segments juxtaposed with said winding roll and arrayed along said winding roll, said contact roller segments pressing said web against said at least one winding roll and having respective ends, with the ends of neighboring pairs of said contact roller segments facing each other;
a respective frame carrying each of said contact roller segments and movable in a direction perpendicular to the respective contact roller segment for displacing the respective contact roller segment toward said at least one winding roll;
and
two lateral support plates on each of said frames, extending parallel to ends of a respective contact roller segment and engaging respective said ends of the respective contact roller segment to support the respective contact roller segment for free rotation on the respective frame,
the support plates of each contact roller segment being offset from the support plates of the neighboring contact roller segments perpendicularly to said direction.
