<p>A knitting machine is described for knitting rows of yarn loops in a helical pattern around the inner core of a hose. The machine comprises at least two concentrically disposed tubes. The first tube rotates concentrically around a straight axis along which the inner core of a hose moves towards an opening in a knitting head. The first tube carries a plurality of needles and needle guides which are equally spaced from, and around, the opening in the knitting head. The second tube concentrically rotates independently around the first tube and carries, i) at least one yarn deck, ii) cams which reciprocate the needles when the first and second tube differentially rotate, and iii) the knitting head. A stationary third, rigid, hollow inner tube can be concentrically disposed withinthe first tube to guide the inner core to the knitting head.</p> |
