A system and method for managing the feed of a plurality of yarns at constant tension and/or velocity to a textile machine of circular, loom or yarn preparation type, the yarns being fed to the machine by a corresponding plurality of feed devices. Setting controller is provided, connected to the plurality of devices and arranged to set their operation, the setting controller receiving synchronization signals from the machine and measuring on the basis of these signals every portion of an article production cycle, the cycle being divided into different stages, the setting controller acting on each individual feed device on the basis of the stages such that each feed device feeds the respective yarn with predefined tension and/or velocity individual to each of the stages. |

1. A system for managing the feed of a plurality of yarns at constant tension and/or velocity to a textile machine of circular, loom or yarn preparation type, said yarns being fed to said machine by a plurality of feed devices, comprising
setting control means connected to said plurality of devices and arranged to set their operation, said control means receiving synchronization signals from the machine and measuring on the basis of these signals every portion of a production cycle or of the working advancement state of an article or of a production process, said production cycle being divided into different stages, the control means for acting on each individual feed device on the basis of said stages such that each feed device feeds and/or controls the respective yarn with predefined tension and/or velocity individual to each of said stages, wherein the setting control means comprises an interface, command and control unit, wherein the synchronization signals originating from the textile machine comprise at least one signal corresponding to each revolution undergone by a cylindrical operating member of said machine, for each stage of the article production cycle corresponding to the manufacture of each part or zone of the article, said stage being defined and measured by the interface, command and control unit by means of said synchronization signals, values are set for at least one characteristic of the yarn fed by each feed device, said characteristic comprising at least one from tension, velocity, and yarn presence, said interface, command and control unit programming these values set on the feed devices, the values of each fed yarn characteristic are tabulated within the interface, command and control unit such that at each individual part or zone of the manufactured product, for each individual revolution of the machine cylindrical member and for each individual feed device, a set datum is scheduled with which to possibly compare the corresponding current value measured by the interface, command and control unit of the feed device. |
