Abstract
A folding mechanism cylinder having a diameter that can be adjusted during operation of the cylinder. Adjustable bands are arranged on the outer jacket of the cylinder and are moved by rotation of spindles that are connected to the bands by gears. One of the spindles is arranged in the hollow shaft of the cylinder and drives all the other spindles.
Claims13
An adjustable diameter cylinder for a folding mechanism to allow for different length folds, comprising:
- a cylinder body formed as a hollow shaft and having a longitudinal axis and a cylinder jacket;
- adjustment strips movably arranged on the jacket transverse to the longitudinal axis so as to change the cylinder diameter;
- a first spindle mounted in the hollow shaft;
- superimposing gear means for rotatably driving the first spindle;
- a plurality of further spindles mounted in the cylinder body so as to be rotatable;
- first connecting means for connecting the strips to the plurality of further spindles so that rotation of the further spindles moves the adjustment strips;
- and
- second connecting means for connecting the first spindle to the plurality of further spindles so that rotation of the first spindle imparts rotation to the plurality of further spindles which in turn move the strips transverse to the longitudinal axis so as to adjust the cylinder diameter while the cylinder is in operation.
