Abstract (en)

[origin: EP1225149A2] A laser sensor (34) that determines its distance from the bobbin surface by timing the difference between the transmitted and reflected beam (35) is fitted to a winder, especially for winding freshly spun glass fiber rovings (24). The sensor (34) can be mounted on the frame (10) or on the traverse (20) and is placed in a housing pressurized with air that sweeps the beam aperture. An Independent claim is also included for a winder that is fitted with such a sensor and uses the bobbin diameter signal to control the bobbin spindle speed. The rate of growth of bobbin diameter can also be used to measure the roving thickness and apply corrections to the extrusion temperature.
