摘要： A device for the electronic adjustment of hosiery tension in circular textile machines, whose particularity consists of the fact that it comprises an actuator which is adapted to move a carriage, which is in turn adapted to perform a translatory motion along an axis which is parallel to a diametrical axis of the circular textile machine, the carriage supporting at least one transducer connected to a hosiery advancement device, the transducer being adapted to detect a contrasting force which is due to the advancement of the hosiery item, the contrasting force being processed in a controller which is adapted to emit a speed signal for the actuator, in order to adjust the movement speed of the carriage in contrast with the contrasting force.

摘要： A method for determining the size of the stitch loops in sock-production machines by means of a control unit which stores three pairs of values for each of a plurality of different types of yarns with which each of a plurality of machine zones is to be produced. Each pair of values includes the relative height and the corresponding width of the knitted product, the specific length and corresponding width of the knitted product, and the height of the stitch-formation triangles and corresponding specific length of the knitted product. The width and type of yarn is selected for each zone to be produced, and the relative height corresponding to the selected width and type of yarn for each zone is determined by the control unit by means of an equation which represents a straight line. The rotational speed and angular position of the machine cylinder is measured and fed to the control unit, which then sends signals to step motors. The value for the width stored in the control unit is derived by an autocalibration procedure which utilizes an equation which represents a straight line.
