Patent ID: 8875545

Claim:
Knitting head for knitting machine adapted for manufacturing flexible hoses having a knitted reinforcement layer overlapping a tubular bearing layer, comprising: a guide body with a central tubular conduit for passage of the bearing layer, said conduit defining a longitudinal axis and having an outlet end portion with a first external peripheral surface with a predetermined first radius; a plurality of knitting needles peripherally distributed around said end portion of said conduit and having first longitudinal end lengths circularly placed on said external peripheral surface and second longitudinal end lengths placed on a second cylindrical surface having a second radius greater than said first radius; at least one discoidal cam element rotatable about said longitudinal axis with a first rotation speed and having a predetermined third radius, said cam disk-element being operatively connected with said second longitudinal lengths of said needles to promote their longitudinal oscillation; wherein said third radius is greater than said second radius and fastening means are provided for fastening said discoidal cam element to said second end lengths of said needles, said fastening means having at least one longitudinal portion with a radial dimension decreasing from said third radius to said second radius.
