Means for controlling the movement of yarn carriers along with a carriage in flat knitting machines

Claim 2

Means for controlling the movement of yarn carriers along with a carriage in a flat knitting machine, comprising a trick location detector mounted on the carriage for detecting varying positions of the carriage on a needle bed during its movement thereon, each such position expressed in terms of the number of tricks or of needles counted from one or the other tricked end of the needle bed, a plurality of solenoids arranged in a plunger box on the carriage for individually controlling coupling plungers provided in the plunger box in the same number as the solenoids, each coupling plunger slidable to an operative position relative to one of the yarn carriers on carrier guide rails for engagement therewith, each of said solenoids connected to a solenoid drive circuit, trick position setting means adapted to memorize predetermined signalling positions, each expressed in terms of the number of tricks counted from one or the other tricked end of the needle bed, for selectively energizing and deenergizing the solenoids, and a control unit for controlling the solenoid drive circuit through the operation of values memorized by the trick position setting means and those detected by the trick location detector.

Claim 3

Means for controlling the movement of yarn carriers along with a carriage in a flat knitting machine, comprising a trick location detector mounted on the carriage for detecting varying positions of the carriage on a needle bed during its movement thereon, each such position expressed as the number of tricks or of needles counted from one or the other tricked end of the needle bed, a plurality of solenoids arranged in a plunger box on the carriage for individually controlling coupling plungers provided in the plunger box in the same number as the solenoids, each coupling plunger slidable to an operative position relative to one of the yarn carriers on carrier guide rails for engagement therewith, each of said solenoids connected to a solenoid drive circuit, trick position setting means adapted to memorize predetermined signalling positions, each expressed in terms of the number of tricks counted from one or the other tricked end of the needle bed, for selectively energizing and deenergizing the solenoids, number-of-tricks modifier setting means adapted to set and memorize signalling-position modifiers, each expressed as a plus or minus value relative to the value for the predetermined signalling position expressed in terms of the number of tricks counted from one or the other tricked end of the needle bed, for altering predetermined signalling positions for selectively energizing and deenergizing the solenoids, and a control unit for controlling the solenoid drive circuit through the operation of values memorized by the trick position setting means and number-of-tricks modifier setting means and those detected by the trick location detector.

Claim 4

Means for controlling the movement of yarn carriers along with a carriage in a flat knitting machine, comprising a trick location detector mounted on the carriage for detecting varying positions of the carriage on a needle bed during its movement thereon, each such position expressed as the number of tricks or of needles counted from one or the other tricked end of the needle bed, a plurality of solenoids arranged in a plunger box on the carriage for individually controlling coupling plungers provided in the plunger box in the same number as the solenoids, each coupling plunger slidable to an operative position relative to one of the yarn carriers on carrier guide rails for engagement therewith, each of said solenoids connected to a solenoid drive circuit, trick position setting means adapted to memorize predetermined signalling positions, each expressed in terms of the number of tricks counted from one or the other tricked end of the needle bed, for selectively energizing and deenergizing the solenoids, number-of-tricks modifier setting means adapted to set and memorize signalling-position modifiers, each expressed as a plus or minus value relative to the value for the predetermined signalling position expressed in terms of the number of tricks counted from one or the other tricked end of the needle bed, for altering predetermined signalling positions for selectively energizing and deenergizing the solenoids, and a control unit for controlling the solenoid drive circuit through the operation of values memorized by the trick position setting means and number-of-tricks modifier setting means and those detected by the trick location detector.
