Abstract: A device for adjusting gram force applied to a thread in knitting machines, comprising a control unit that is adapted to drive a power supply device of a motor for unwinding a thread to be fed to the knitting machine, a gram force sensor adapted to detect the gram force applied to the thread and to emit a gram force signal, a comparator adapted to compare the gram force signal with a reference signal in order to obtain a gram force error signal; the control unit comprises elements adapted to emit a signal for driving the power supply device of the motor according to the gram force error signal of the thread and to a signal that is the derivative with respect to time of the gram force signal emitted by the gram force sensor.

Abstract: A method for trimming loose threads in circular knitting machines, comprising the steps of: starting from an initial pattern and on the basis of a given type of circular knitting machine, if one wishes to trim the loose threads, measuring a distance between needles of the same color on a same row in order to check whether the distance is at least equal to, or greater than, a minimum distance that allows to perform trimming of the loose threads; if the distance is shorter than the minimum distance, replacing a portion of the pattern with at least one special color that identifies a different type of knitting process for the portion of pattern, to be performed on the circular knitting machine; modifying the pattern on the basis of the replacement of the portion of pattern; producing an advancement by a number of rows equal to the number of drops of the knitting machine that are active; and encoding the pattern with the modifications, in order to perform the knitting process.
