Abstract
Abstract A knitting machine, in particular a flat-bed knitting machine with a plurality of needle beds in each of which longitudinally extending needle tricks are formed in which a knitting needle moves longitudinally. The knitting needles comprise two parts, with one part including a needle head and the other part including a needle butt. The needle head defines a stitch forming part and the needle butt defines a movement-initiating part. A coupling device is provided for each needle to couple the two parts together. A coupling operating device is provided on the cam box carriage for operating the coupling devices in such a manner that the stitch forming part which has knitted is separated from the movement-initiating part until such time as the needle is again selected.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
144 words
A knitting machine, in particular a flat-bed knitting machine, comprising: a plurality of needle beds in each of which longitudinally extending needle tricks are formed; a cam box carriage operatively associated with the needle beds; a knitting needle disposed in each needle trick of each needle bed to move longitudinally in its respective needle trick, each knitting needle comprising two parts, with one part including a needle head and the other part including a needle butt, the needle head defining a stitch forming part and the needle butt defining a movement-initiating part; a coupling device for each knitting needle for coupling the two parts of the knitting needle; and a coupling operating device provided on the cam box carriage for engaging and thereby operating the coupling devices to couple and uncouple the stitch forming part of each needle with respect to its movement-initiating part.
Claim 2
Dependent Claim
144 words
A knitting machine, in particular a flat-bed knitting machine, comprising: a plurality of needle beds in each of which longitudinally extending needle tricks are formed; a cam box carriage operatively associated with the needle beds; a knitting needle disposed in each needle trick of each needle bed to move longitudinally in its respective needle trick, each knitting needle comprising two parts, with one part including a needle head and the other part including a needle butt, the needle head defining a stitch forming part and the needle butt defining a movement-initiating part; a coupling device for each knitting needle for coupling the two parts of the knitting needle; and a coupling operating device provided on the cam box carriage for engaging and thereby operating the coupling devices to couple and uncouple the stitch forming part of each needle with respect to its movement-initiating part.
