Abstract
In a web guidance device, particularly for a continuous form printer device, deflection seat is provided around which a recording medium web is guided in a conveying direction. A lateral guide roller influences the recording medium web with a laterally acting force in a region of a deflection seat such that the recording medium web lies against the lateral detent. A planarly acting hold-down element is provided in a region of a lateral guide roller, the hold-down element pressing the recording medium web onto the deflection seat with a specific pressing power.
Claims10
A guidance device for a continuous form printer device, comprising:
- a deflection element across which a recording medium paper web is guided in a conveying direction;
- a lateral guide roller that influences the recording medium web with a laterally acting force in a region of the deflection element such that the recording medium lies against a lateral detent;
- and
- a hold-down element arranged preceding the lateral guide roller in the conveying direction in a region of the lateral guide roller, said hold-down element pressing the recording medium onto the deflection element with a specific pressing power.
A web guidance device for a continuous form printer device, comprising:
- a curved deflection seat around which a recording medium paper web is guided in the conveying direction;
- a lateral guide roller that influences the recording medium web with a laterally acting force in a region of the deflection seat such that the recording medium web lies against a lateral detent;
- and
- a hold-down element in a region of the lateral guide roller having a curvature substantially matched to a curvature of a deflection seat, said hold-down element pressing the recording medium web onto the deflection seat.
A method for guiding a web in a printer device, comprising the steps of:
- guiding a recording medium web along a deflection element in a conveying direction;
- with a lateral guide roller, applying a laterally acting force in a region of the deflection element such that the recording medium lies against a lateral detent;
- and
- with a hold-down element provided in a region of the lateral guide roller and preceding the lateral guide roller in a conveying direction, pressing the recording medium web onto the deflection element.
A method for guiding a web in a printer device, comprising the steps of:
- guiding a recording medium web around a curved deflection seat in a conveying direction;
- with a lateral guide roller, applying a laterally acting force in a region of the deflection seat such that an edge of the recording medium abuts against a lateral detent;
- and
- with a hold-down element provided in a region of the lateral guide roller and having a curvature matched to a curvature of the deflection seat, pressing the recording medium web onto the deflection seat with a specific pressing power.
