Abstract (en)
[origin: EP0290064A2] The present invention relates to an improvement which gives a greater strength to the bars (10) equipped with a plurality of needles (3), and to be used in combination with a plurality of other similar bars in the rotary-head drawing devices. In the rod-shaped body of the comb bar two narrow longitudinal slots (2,4) are provided, each of them being spaced apart from the other one by a distance substantially positioned astride the middle of said bar. Each one of the above-said longitudinal slots houses the butt (5) portion of a plurality of needles operating on one or more fibre bands. The length (12) interposed between two consecutive longitudinal slots is strengthened, in that it shows a larger cross-section than the bar cross-sections in correspondence of the needles.
