Embodiment Construction

[0030] In devices that control the lateral deflection of sheets of material, such as Figure 1A and 1B As shown, at least one orientation feature may be used to determine lateral offset of the sheet of material relative to a predetermined position. The at least one orientation feature may for example be a line or a pattern on the sheet of material. This orientation feature may proceed in the direction of travel of the sheet of material and may be located near an edge of the sheet of material or may be the edge itself. The sensor element in this case may be a photosensor, such as a color sensor or a camera.

[0031] Figure 2A A sheet of material with lines as orientation features is illustrated. exist Figure 2A In a) of a), the line 210 on the sheet of material 200 is being sampled in the sensor area 220 . Figure 2A Solid lines are shown in a) and c) in stable and "cluttered" backgrounds, respectively. exist Figure 2A Dashed lines can be seen in b) and d) in stable a...

Abstract

The present invention relates to an equipment and process for detecting orientation characteristics on a web of material, wherein the web of material web advances on a scheduled material web location along scheduled advance direction. On one hand, the device comprises a sensor device, which includes a sensor element that used to for recording at least one sensor line in sensor area of the material web. The device also comprises a light transmitter that used to generate at least one luminescent spot on the material web to judge location of the material web that bias the scheduled material web location. On a second hand, the sensor element comprises at least two sensor lines, and at least part of the at least two sensor lines along material web advance direction of the sensor element can be read, so as to acquire integration result of the sensor area in the material web along material web advance direction. On a third hand, the sensor element is set at a inclined position relative to the scheduled material web location.

Description

technical field [0001] The present invention generally relates to apparatus and processes for detecting oriented features on a material web. Background technique [0002] During the handling and handling of sheet material, sheet guidance control is used. For example, sheets of material may be fed into a machine, processed and then rewound through winding equipment, so various positioning errors may occur. For example, to guide the lateral deflection of the material sheet, suitable control devices can be used. [0003] Figure 1A and Figure 1B An adjustment apparatus is shown in which a sheet of material 100 of width B undergoes four turns of 90 degrees each, assisted by a turning frame system. The sheet of material is deflected by a feed roller 101 and a feed length Li is fed into a pivoting frame 105 by two guide rollers 102 , 103 . Lateral adjustment of the sheet of material can be achieved by pivoting the frame 105 . The sheet of material is then pivoted at pivot po...
