Apparatus for rolling up a web of material

An apparatus for rolling or winding up a web of material comprising:

• a driven supporting roll;
• one or more winding rolls on which said supporting roll contact during the winding process;
• at least one pivoting lever mounted laterally adjacent at least one of said winding rolls pivotable upwardly and comprising two parts attached to each other slidably and spring-loaded so that said pivoting lever has a variable length;
• at least one carriage which is slidable on at least one cross piece transverse to said web on which at least one of said pivoting levers is mounted;
• a piston-and-cylinder unit attached to said carriage and said pivoting lever, said unit operating as a drive for a pivoting motion;
• and
• at least one press roll pair pressable against a circumference of one of said winding rolls mounted pairwise on an end of at least one of said pivoting levers, each of said press rolls in said pair having a longitudinal rotation axis which is parallel to an axis of said supporting roll, said press roll pair being supported movable on said pivoting levers about a second axis approximately parallel to the length of said pivoting lever and additionally supported movable about another axis which extends approximately perpendicular to said length of said pivoting lever and perpendicular to said longitudinal rotation axes.
