PROCESS AND DEVICE FOR MONITORING SINGLE STRANDS IN STRANDING PROCESSES

摘要

ABSTRACTFor monitoring stranding machines for breakage or run-outof single strands, a device is employed which checks therope or cable after stranding for uniformity of the ropeor cable surface.For this purpose, an electrical image of the rope orcable surface is read into a memory and the measuredvalues compared with this stored pattern during the furtherstranding process. In the event of deviations resultingfrom this comparison, disconnecting or other actuatingelements are actuated in order to avoid the productionof further faulty lengths of rope or cable.For reflection measurements, electromagnetic, optical oracoustic waves can be employed.Instead of scanning of the rope or cable surface basedon reflection, corpuscular radiation which partiallypenetrates the rope or cable can be employed.
