    Patent number: 6964230
    Abstract: An improved method of and an improved apparatus for detecting and correcting unsatisfactory patterns of adhesive is applied to a running web of paper or the like in a tobacco processing machine by a cyclically operated paster. A linear scanning camera is employed to take pictures of groups of at least some of the patterns which are applied during successive cycles of the paster, and such pictures are displayed and compared with a reference image of satisfactory patterns and preferably also with additional reference images. The results of comparison are relied upon for the making of corrections, for example, by changing the operation of the paster and/or by changing the direction of advancement of the web between the paster and the camera.
