Definitions
- the present invention generally finds application in the art of flexible hoses, and particularly relates to an irrigation hose having a double knitted layer.
- the invention also relates to a method of making such hose, a line for manufacturing same and a knitting apparatus for making such hose.
- FIG. 6 is a schematic view of a second embodiment of the knitting apparatus for making the hose of the invention
- FIG. 7 is a schematic enlarged view of a knitting section of the apparatus of Fig. 5;
- the reciprocating motion of the needles of the first series 26 and those of the second series 27 have opposite directions, so that the forward motion of a needle of the first series 26 causes the facing needle in the second series 27 to move towards the same central reference plane.
- the first column shows the torsion angle value obtained by blowing air at a pressure of 3 bar into a one meter-long hose specimen, held in vertical position by supports that allow it to rotate about its own axis.
- the angle of rotation (degrees) of the hose was measured using a goniometer attached to the base of the hose.
- the three hose specimens under test had the same interior diameter, 15.88 mm (5/8 inches, 5/8").
- the second column shows the burst pressure value obtained according to the standard UNI EN ISO 1402:1997 (Rubber and plastic hoses and hose assemblies. Hydrostatic tests).
- numeral 9 designates a "false loop", also differentiated by broken lines, which is formed of the transverse portion 9' of the stitch 6 of the first textile layer 4 and the transverse portion 9" of the stitch 6' of the second textile layer 5, which are in side by side relation.
- the "false loops” will form together “wales” of “false loops” parallel to the axis X of the hose.
