Different Parts of Knitting Head of the Straight Bar Frame

Different Parts of Knitting Head of the Straight Bar Frame
Figure: Shows the cross-section of the knitting head containing the following elements

A. Bearded needle, having a cranked end for location in the tricked and drilled needle bar.

B. Sinker – only one between every other needle space – with a reinforced back and, at the front, a ‘catch’ to sink the yarn around the needles, and a ‘neb’ to separate the old and new loops until knock-over.

C. Divider, occupying each remaining space, usually having the same shaped front as the sinker but with an extended tail at the back.

D. Knocking-over bit – one directly beneath each sinker and divider – having a ‘throat’ for holding the loops and a ‘nose’ for knocking-over.

E. Needle bar, having a compound horizontal and vertical movement.

F. Striking jack, fulcrummed at its lower end, each one with its ‘nose’ resting on a sinker back, and a ‘spring’ exerting pressure on its ‘tail’.

G. Catch bar, extending the full width of the knitting head, having forward and backward, as well as vertical, movement.

H. Yarn carrier, which traverses in alternate directions across the head from one course to the next – up to six carriers may be available.The carrier is connected to a reciprocating carrier rail by friction, and when the carrier is arrested by its carrier stop, the carrier rail completes its full traverse, driven by the coulier cam and punching through the carrier friction.

J. Falling bar, which is a stop that cushions the advance of the sinkers and dividers.
