摘要： Vertically stacked drive wheels (17.sub.1, 17.sub.2, 17.sub.3 and 17.sub.4) are provided above a yarn feed wheel (21) which is provided with a first yarn feed surface (27) providing comparatively high friction with the yarn engaged thereby and adaptable for use when the rate of yarn feeding varies, such as in the case of Jacquard pattern knitting, and a second yarn feed surface (28) providing comparatively low friction against the yarn engaged thereby and adapted for use when the rate of yarn feeding is constant, such as in the case of plain knitting. Manually adjustable yarn guide means (29, 30) is provided for selectively guiding yarn to the first and second yarn feed surfaces (27, 28). Clutch members (24, 24') are interposed between pairs of the vertically stacked drive wheels and are selectively operable to impart rotation to the feed wheel (21) from a selected one of the drive wheels.

摘要： An attachment for use with multi-feed circular knitting machines of the type having a rotary needle cylinder and having yarn striper boxes at the feeds thereof. The boxes serving to change and to cut and clamp the yarns fed to and knit by the machine during the making thereon of coursewise striped fabric. The yarn changing operation resulting in undesirably long unknit terminal portions of the changed yarns extending inwardly from the inner side of the tubular fabric being made. The terminal portions of the yarns having cut ends. The attachment comprising a device having yarn clipping means disposed within the tubular fabric and rotating in unison with the needle cylinder to cut and to shorten the terminal portions of the changed yarns as the tubular fabric continues to be made, whereby the yarns are cut firstly by the striper boxes and secondly by the yarn clipping means.
