Method for supervising glue spreading, comprises light source and captor which move in translation but not rotation with glue nozzle and take continuous pictures to check glue movement and thickness

摘要

A glue nozzle (2) moves in translation and rotation to produce a spiral thread (5) on a surface (3) as a ribbon (13). A light source (7) and mirror (8) illuminate the spiral, and light from the spiral (12) is reflected by a mirror (11) to an optical captor with an image processor. The optical system moves with the nozzle in translation but not rotation and continuous pictures reveal the trajectory, frequency and thickness of the glue spiral An Independent claim is also included for : Electronic imaging equipment able to examine a glue spiral continuously and verify trajectory, frequency and thickness
