DEVICE FOR MEASURING THE THICKNESS OF A COMPOSITE FIBER RIBBON ON A STRETCH BENCH, PARTICULARLY A REGULATING STRETCH BENCH

摘要

P Device for measuring the thickness of a fiber composite tape on a drawing bench, comprising a ribbon guide (2) at the entrance of the bench, with conical walls for grouping in a plane the ribbons of incoming fibers, and followed by a pair of cylinders (4), after which the ribbons diverge. The guide (2) is associated with a loaded and movable probe (22) which forms a constriction for the composite ribbon with a fixed counter-surface (34) and whose position modification acts when the fiber ribbon has different thicknesses. on a conversion member (33) for producing a control pulse. The ribbons in the guide (2) are compressed and palpated in a plane and the pair of rolls (4) pulls the ribbons of felt fibers. BR/ When modifying the kind or number of the ribbons, to improve the guidance of the ribbons, the complementary element (34) is rotated (A) about an axis (36) perpendicular to the plane of the fiber ribbons. / P
