Abstract
A device for joining textile yarns for joining two ends of two textile yarns by decomposition and subsequent re-composition of the twists of the fibers of the ends in order to make up a single yarn, including two counter-rotating components, each provided with at least one joining element and disposed opposite each other defining a joining zone defined by the area between the respective joining elements facing each other and substantially aligned along a work axis.
Claims14
A device for joining textile yarns for joining the opposite ends of two textile yarns by means of decomposition and subsequent re-composition of the twists of the fibers of said ends in order to make up a single yarn, the joining device comprising two counter-rotating components, each provided with at least one joining element and disposed opposite each other defining a joining zone between the respective joining elements facing each other and substantially aligned along a work axis, wherein the joining device comprises:
- one or more motor members configured at least to selectively move at least one of the components along the work axis so as to adjust the width and size of the joining zone and to selectively rotate the components with respect to each other about the work axis to obtain the decomposition and the subsequent re-composition of the twists of the fibers of the yarns;
- a control unit having an internal memory provided with a list of functioning parameters of the two components for joining said the yarns, the control unit being configured to control and command the one or more motor members on the basis of the functioning parameters present in the internal memory.
A method for joining the opposite ends of two textile yarns by means of decomposition and subsequently re-composition of the twists of the fibers of the ends in order to make up a single yarn, the method comprising:
- introducing two yarns to be joined between two components, each provided with at least one joining element and disposed opposite each other defining a joining zone between the respective joining elements facing each other aligned along a work axis;
- bringing the two components close to each other along the work axis until there is at least partial contact between the facing joining elements;
- rotating the two components in opposite directions to each other so as to bring the two yarns close and parallel to each other in the joining zone;
- removing the end parts of the yarns which will not contribute to the joining, obtaining the two ends of the two yarns to be joined;
- bringing the ends of the two yarns to be joined close together until they substantially overlap;
- counter-rotating the two components in opposite directions to each other so as to twist the opposite ends of the two yarns in order to create a single yarn;
- aid method wherein it also comprises making available in an internal memory of a control unit a list of functioning parameters of the components for joining textile yarns, wherein the control unit, as a function of the functioning parameters, commands and controls one or more motor members assigned to executing one or more of the steps of introducing the textile yarns into the joining zone, bringing the two components close together, rotating the two components, removing the end parts of the yarns, bringing the ends of the yarns obtained close together and counter-rotating the two components.
