Abstract
A circular knitting machine includes a cylinder with knitting instrumentalities and a cam arrangement for operating the instrumentalities, the cylinder and the cam arrangement being relatively rotatable, a striper associated with the cam arrangement and having a yarn cutting mechanism, an aperture in the cylinder for propelling air outwardly of the cylinder past the instrumentalities to carry yarn ends cut off by the yarn cutting mechanism outwardly of the striper and a means for collecting yarn ends carried outwardly by the air. The machine can be used in combination with a striper which includes a plurality of yarn feeding fingers movable into and out of a feeding attitude, a trapping mechanism for entrapment of ends of yarn not being fed, a cutting mechanism for severing a yarn previously fed to enable it to be trapped and for severing a yarn newly fed to the needles to free it from entrapment, and a guide associated with the trapping and cutting mechanism for confining yarn ends dropping from the mechanisms to enable them to be carried away from the striper by a flow of air.
