Problems solved by technology

In this type of line tensioner, once the weight and relay have been selected and installed, the configuration of the line tensioner and the tension applied to the line cannot be adjusted in any way
In utility models JP5117547 and JP5130235, the diverter elements include eyelets in which the wire is slotted, which makes the use of these diverter elements in normal automatic winding machines problematic

Abstract

Device for tensioning a winding thread (2) in textile machines comprising a plurality of stationary deviator elements (22, 54) and a plurality of displaceable deviator elements (27, 47) arranged like a comb facing one another in a staggered and opposed manner so as to form a tortuous path for the thread that passes through the device, in which such deviator elements are provided with sliding elements (38) elastically contrasted to move forth and back against the thread, each sliding element (38) being capable of moving independently from each other, in which the tortuousness of the path is adjusted with a mobile device (26) that modulates the load of the elastic elements (39, 49) working in contact with the thread, to obtain the desired tension in the thread in outlet from the thread tensioning device.

Description

technical field [0001] The present invention relates to a device for generating and adjusting the tension (known as tensioning) of a winding thread in a textile machine. Background technique [0002] In the textile industry, many processes of producing and trimming yarns require adjusting the tension of the winding thread, however, in order to make the technical problems addressed and solved by the present invention and the characteristics and advantages of the present invention over the prior art more clear, The invention is described hereinafter with reference to a winding process carried out in a winder in which the processed thread is unwound from a bobbin and rewound in a package (package). As is known, a winder comprises a plurality of bobbin units arranged along the front of the machine and provided with common control and maintenance equipment. [0003] The base part of the spool unit is in the figure 1 As shown in , those components not directly related to the tec...
