- Guide rollers of this type are used in particular at the exit of a rotary printing machine used, if applicable, several partial webs, in which one of the Rotary printing machine printed paper web has been cut, and the lying side by side leave a cutting device, so to redirect that they one above the other, possibly folded and further processed.
- DE 34 36 870 C1 discloses a turning bar with axially displaceable piston.
- turner bars are known which with a compressed air-supplied interior are formed.
- the coat of the turning bar is on At least a part of its circumference provided with holes, through the air from the Interior space can escape to an air cushion between the turning bar and the To form material web.
- pistons are used, which at their the interior facing side are not plan, but have edges, their course respectively one half of its scope to a right-handed and the other half to one corresponds to left-handed helix.
- the pistons are in the turning bar around their Rotatable axis, so that, depending on which direction the material web is deflected, one or the other of the two helical edges to the perforated Part of the circumference of the shell can be turned out, which is to be deflected by the Material web is entwined.
- JP 11-246098 A describes a loadable with air guide roll whose coat with Holes is provided. These holes are hydraulic by means of one in the interior slidable locking element depending on a web width selectively closed. For detecting the web width sensors are arranged.
- the invention is based on the object, a guide roller for guiding a web to accomplish.
- the achievable with the present invention consist in particular that a Adjustment of the position of the piston to the width or the position of a material web the guide roller can be done quickly and selectively. Even an adjustment of the position of Piston to a web displacement while the web is running is readily possible.
- Control signal for the control circuit come in particular two types of signals
- a quantitative signal d. H. a signal with a numerical value can be assigned and that allows the control circuit, the engine so long to operate until the piston has reached a position corresponding to the numerical value
- a signal with at least two discrete states one of which as can be called “forbidden” and the other as “allowed” state, in which case the controller may be to operate the engine until the signal in goes over the "allowed” state.
- the first type of control signal is particularly suitable for attaching it to one of the guide rollers upstream, the web-processing device such as a Tapping tool, whether by measuring the position of a device, the determines the position of a web edge or directly by deriving from a control signal, which determines the position of such a device.
- the web-processing device such as a Tapping tool
- the position of an edge of the material web by means of a sensor directly determine or that the target value from a memory device z. Eg control room is given.
- a control signal of the second type can preferably by means of a to the respective Position of the piston coupled movable detector to detect the position of the Web edge are generated.
- the coupling can be a mechanical connection between piston and detector include; but it comes, especially if the Detector of the guide roller is arranged on the path of the material web, a control technology coupling into consideration.
- the quick and targeted adaptability of the piston position is particularly important in a pivotable guide roll, the deflection of the web optionally in two different directions allowed.
- the process of positioning the piston can be so be fully automated, making the switch to different web widths and optionally deflection directions further simplified.
- Another advantage is that after a pivoting of the guide roller a separate Operation of turning the pistons to adapt their edge profile to the Course of the web edges deleted.
- the air pressure of the interior against the edges of the slot pressed sealing tape can advantageously be provided.
- the latter is preferably coupled to the piston and before the Slidable.
- the detector may also be within the piston for detecting presence or absence of the web of material in front of one of the holes.
- the guide roller can be pivoted by 90 ° about an axis perpendicular to its longitudinal axis is to redirect a web optionally in opposite directions, so describe the edges of the material web on the surface of the guide roller depending on Direction of turning a left-handed or a right-handed helix.
