Abstract

The hook needle type knitting machine for the manufacture of ribbons comprises weft thread guiding means which include a pair of vertically movable side plates which support for axial movement at least one bar supporting the weft guides. The bar has a circular cross-section and is protected against inflections and rotation about its axis by an intermediate clamping member and a guiding rod slidably passing through a side plate. The guiding rod is secured to the bar by clamps which act as a thrust member for driving cam mechanism of the bar. The side plates and the needle bed are driven respectively, by a linkage including a driving eccentric shaft and a connecting rod. The needle bed is supported on two pivotable arms the length of which substantially exceeds the arcuate displacement of the needles so that this displacement can be considered as rectilinear.

Claims9

Dependent claims

In a knitting machine having a plurality of hook needles adapted for forming and discharging chains of loops for warp threads, a reciprocating bed adapted for movably supporting said hook needles, warp guiding means for guiding a warp thread to each of said needles, weft guiding means for guiding weft threads to link the loops in respective chains, and means for movably supporting said warp guiding means, a combination comprising:

a pair of opposite side plates arranged for a vertical reciprocating movement above said needles and each defining at least one guiding passage of circular cross-section;
at least one bar having a substantially circular cross-section and having its end portions slidably supported for axial movement in said guiding passages;
said one bar supporting said weft guiding means for axial and vertical movements between a first level below said needles and a second level above said needles;
an intermediate supporting memeber slidably supporting a central portion of said one bar to eliminate inflections of said one bar;
a driving linkage for said side plates including a connecting rod and a toggle lever hinged between said connecting rod and one of said side plates;
supporting means for said bed including a pair of elongated, swingable supported arms;
and a driving linkage for said bed pivotably coupled to said arms.
