摘要： A novel fiber drafting system is disclosed, according to which fibers of sliver supplied continuously are passed through a first pair of rotatable cooperating rollers while being pressed and compacted into a reduced section by and between a space formed by a groove and a projection formed respectively in and on the circumferential peripheries of the rollers of said first pair. The sliver thus compacted is then transferred to and held by and between a second pair of rollers rotated at a higher peripheral speed than the first pair of rollers, whereby the fibers of sliver are drafted successively between the two pairs of rollers without use of conventional aprons for guiding and supporting the fibers in the drafting zone.

摘要： Sliver weight unevenness correcting apparatus of a feed-forward type has: a sliver weight measuring section for detecting the variations in weight of a bundle of slivers; a correcting draft device having front rollers disposed downstream of the sliver weight measuring section relative to the direction of advancement of slivers, the front rollers being rotated at a constant speed, and back rollers disposed between the sliver weight measuring section and the front rollers, the back rollers being rotated at a variable speed; a rotation detector for detecting the number of revolutions of the front rollers; an unevenness correcting circuit having a ratio circuit for operating a ratio (E.sub.0 /E.sub.1) between a reference sliver weight (E.sub.0) and the detected weight (E.sub.1) thereof, a delay circuit for delaying the speed control of the back rollers of the correcting draft device for a predetermined period of time, and a contrasting operational circuit for multiplying the ratio (E.sub.0 /E.sub.1) and a ratio (N.sub.F /k) between the number (N.sub.F) of revolutions of the front rollers and a reference draft value (k) and for producing a multiplied signal (E.sub.0 /E.sub.1 .multidot. N.sub.F /k); and a speed control circuit for producing a speed control signal responsive to the multiplied signal to control the speed of back rollers through a rotation transmitting mechanism. This arrangement enables accurate correction of sliver weight unevenness even short in wavelength in a drawing frame running at a high speed.

摘要： A needle selection control apparatus for circular pattern knitting machines which controls the timing of selection of a series of needles mounted on a needle cylinder. Needle synchronizing signals produced by sensor means which senses each cylinder needle rotating with said needle cylinder are electrically processed so that input pulse signals are formed whose phases have angles of lead controlled by the apparatus in accordance with the number of revolutions of the needle cylinder, and the input pulse signals are also electrically processed so as to remove unnecessary contents of the signals due to the eccentricity of the needle cylinder therefrom. The input pulse signals thus obtained are supplied to needle selector means for actuating the same at very high rotating speeds of the cylinder without error.

摘要： A weft yarn storage unit disposed between a yarn supply package and a weft insertion device for storing a weft yarn to be inserted in the warp shed, comprises a differential yarn feeding device for feeding the weft yarn from the yarn supply package, and a yarn storage means for winding the fed weft yarn therearound by co-operating with the differential yarn feeding device, storing the wound weft yarn therearound and unwinding the stored weft yarn therefrom by co-operating with the weft insertion device, the yarn storage means being continuously rotating in a direction opposite to the direction in which the weft yarn is unwound at a predetermined circumferential speed in response to an insertion speed of the weft yarn. This weft yarn storage unit allows high-speed weft insertion while preventing the yarn breakage by reducing ballooning of the weft yarn when the weft yarn is released off the yarn storage drum.
