Abstract

A winding machine for producing rolls (3) having a pressure roller system which includes a horizontal, vertically movable cross-head (8) to which a series of freely rotatable and individually movable roll segments (9) are secured side-by-side and with bolts parallel to the cross-head (8). In addition, there are piston/cylinder units (10) for adjusting the pressure exerted by the roll segments (9) on the rolls (3). Into the bearing of each roll segment (9) on the cross-head (8) is integrated a component which either increases the bearing pressure as the distance between the roll segment (9) and the cross-head decreases or decreases the bearing pressure as the distance between the roll segment (9) and the cross-head increases. Thus the most uniform possible pressure on all rolls (3) is ensured and negative effects owing to excessive differences in diameter between the rolls (3) are prevented.

Dependent claims

In a winding machine having:

a pair of horizontal and rotating support rollers defining an upwardly open rolling cradle holding a plurality of winding rolls all extending along a common axis;
means for feeding respective webs to the winding rolls, whereby the webs are wound up on the rotating winding rolls;
a horizontal and vertically displaceable traverse extending a full working width of the machine above and parallel to the winding rolls;
a row of coaxial roller segments downwardly engaging the winding rolls underneath the traverse;
respective roller mounts carrying the roller segments on the traverse for vertical movement independently of one another;
and
means for urging the roller segments downward against the winding rolls, the improvement comprising
means including respective elements braced between the traverse and the roller segments for urging the segments downward with a force that decreases as vertical spacing from the traverse increases and increases as vertical spacing from the traverse decreases.
