Title: Flyer braking mechanism - using a light beam with discriminating circuit to allow for fibre flocks in the operating zone
IPC: D01H13/16
Filed: 1976-06-09
Abstract: In a multi-unit spinning and winding machine, the drive to the flyer has to be braked in the event of a slubbing breakage in the outer winding layer on one of the spools. At lease one beam of light is transmitted from a light source to a photodetector on a path running close tothe spools and particularly along the line of the flyers. The incidence of interruption of this light beam through fibre flocks is determined for a given time period. If this interruption rate increases during the given time period, then the drive to the flyers is stopped and brought to rest. The system discriminates between ambient disturbances and a true breakage of the material, partic. in the wound zone, to give a positive braking action only when it is required.
