摘要： A sweater knit fabric containing hard yarn plaited together with bare elastomeric yarn is provided. The elastomeric yarn has substantially uniform draft along each course in the fabric. The fabric is made by a process in which the bare elastomeric yarn is fed under substantially uniform tension to a knitting machine in which yarn demand fluctuates as the fabric is knitted. Sweater knit fabrics are useful in making garments such as sweaters, vests, dresses, pants, skirts, shirts and caps.

摘要： The yarn feed device is adapted to simultaneously feed elastic and non-elastic yarns to the needles of the knitting machine and at predetermined ratios relative to each other. A yarn feed roller is drivingly rotated by the non-elastic yarn as the yarn is consumed by the needles in forming the stitch loops of a knit fabric. The elastic yarn is in engagement with the roller and is fed to the knitting machine needles at a predetermined ratio, relative to the non-elastic yarn. Three different types of yarn feed rollers are disclosed, each being provided with yarn receiving grooves which may be of different diameters so that the yarns are fed at different ratios or under different degrees of tension.

摘要： A yarn feeder intended particularly for flatbed knitting machines and elastic yarns has a yarn tension sensor which is provided with a calibration device. This device lifts the yarn from a peg that is part of the yarn tension sensor, at times in which this can be done without impairing operation of the yarn feeder. Such times are preferably time slots when no yarn feeding is necessary. Once the yarn has been lifted from the peg, a zero point calibration is performed. Zero point drifting of the entire sensor system, including its measurement circuit, can be detected and compensated for.

摘要： The knitting machine is provided with a yarn tension indicator for continuously monitoring the tension of an elastomeric yarn being withdrawn from a yarn supply source and fed to the needles of the circular knitting machine and for providing a constant visual indication to the machine operator of the tension in the running yarn. The yarn tension indicator includes a base plate and a pointer lever supported in a substantially horizontal position and for pivotal movement on the base plate. Fixed guides are provided for directing the yarn through a movable yarn guide supported for longitudinal adjustment on the pointer lever to urge the same in an upward direction. Weights are supported for longitudinal adjustment on the pointer lever for urging the pointer lever in a downward direction so that when the tension in the running yarn is proper, the pointer lever maintains a horizontal position which may be easily observed by the knitting machine operator.

摘要： A yarn feeder, particularly for elastic yarns having a high elongation coefficient, in circular knitting machines. The feeder comprises a series of passages and/or contact regions forming a path for the yarn that unwinds from the spool or reel up to the needle work area of the machine. The feeder comprises, along the path, an element which can engage the yarn and can move on command in order to lengthen the yarn path so as to produce an excess length of yarn unwound from the spool with respect to the length of yarn required by the machine and so as to supply at least part of the excess yarn directly before yarn cutting, which is performed proximate to the needle work area of the machine.

摘要： An automated unspooling mechanism capable of dispensing of knitting material strands in a dynamically-controlled tension on a knitting machine. An unspooling device is configured to sense the tension of a strand fed to the knitting machine, and responsively adjust the strand deployment speed to avoid too little or too much strand dispensing without interrupting the knitting process. The unspooling device includes a variable motor drive that can rotate the strand package in various speeds, and a spring arm trigger that can sense the current tension of the dispensed material. The spring arm trigger can vary its arm position based on the sensed tension. The arm position is then processed and converted to a signal to vary the motor speed. Therefore, the deployment speed of the strands can be dynamically controlled based on a sensed tension of feeding the strand.

摘要： A yarn recovering device for textile machines, arranged upstream of a textile machine for temporarily recovering a length of yarn previously fed to the machine, and for returning it subsequently. A motorized reel has a substantially axial inlet port and an outlet port on its lateral surface, with a passage for the yarn between the ports. The reel is operatable to rotate from a resting configuration, in which it is kept still, to an active, yarn-recovering configuration, in which it is driven in one direction for winding the yarn on itself and recovering it from the machine, to a subsequent active, yarn-unwinding configuration, in which it is driven in the opposite direction for unwinding the yarn from itself and returning it to the machine. A position sensor measures the position of the reel and sends a corresponding measured position signal to a position control loop which compares the measured position signal with a reference position signal corresponding to a desired position for the motorized reel, and drives the reel in such a way as to minimize the difference between the measured position and the desired position.
