Apparatus for reading coding on a moving coding carrier, especially a travelling fabric web |
摘要 |
A device for reading code lines on a moving carrier in which the lines extend transverse to the direction of movement. The reading head extends across the web and has a row of sensors subdivided into groups. The sensors of each group have a length equal to the maximum length of the coding traces and the total row has a substantially greater length so that the sensors are subdivided along the row into groups. The signals from sensors of preceding groups in a direction of signal flow along the row are summed e.g. at operational amplifiers before being summed with the corresponding sensor outputs of subsequent groups.
