Embodiment Construction

[0020] Referring to the drawings, and in particular to Figures 1 and 2, there is shown an apparatus 1 for feeding a stretch yarn 11 into a textile machine 10 at "constant tension". This device, in Figure 4 Indicated by DTC, including the main body 2 (eg box-like). Attached to the body is a grooved wheel or pulley 3 which is connected to a drive (not shown) for movement. The drive may be an electric motor (for example of the brushless type) connected to the surface of the body 2 opposite the surface 6 on which the pulley 3 is located. Such a device 1 is associated with each elastic yarn 11 to be fed into the textile machine, said yarn being unwound from a bobbin B and wound around a pulley 3 in one or more turns.

[0021] The pulley is directly or indirectly connected to an element 12 which measures the rotation of the pulley and thus the speed of this rotation. This element can be a magnetic sensor 13 connected to the body 2 and cooperating with a magnet 15 connected to a p...

Abstract

A device for controlling the feeding of elastic yarn (11) having known elasticity and withdrawn from a bobbin (B) to be fed to a textile machine (10) such as a knitting machine, hosiery machine, winding machine knitting machine, or other textile machines into which the yarn has inherent elasticity and is fed at an inherent speed, is provided with means (18) for detecting the tension of the yarn (11) and for measuring and means (3, 12) for changing the yarn speed, said detection means (18) and said measuring and changing means (3, 12) are connected to means for controlling and adjusting said tension and speed parameters (20 ), the control and adjustment device (20) continuously measures the values ​​of the two parameters in the process of feeding the yarn (11) into the textile machine, and is characterized in that it also includes a compensating device (30), which compensates the value from the bobbin (B) Dimensional characteristics of the retreated elastic yarn (11) before it cooperates with the tension detection device (18) and the speed measurement device (3, 12), so that the yarn can be fed into the textile yarn with constant dimensional characteristics. Machine (10) for the entire production of textiles. Also disclosed is a method implemented by the device described above.

Description

technical field [0001] The present invention relates to a device for feeding elastic yarns into a textile machine as described in the preambles of the respective independent claims, the purpose of which is to obtain an article of constant quality in each part. The invention also relates to a method implemented by the above-mentioned device as described in the preambles of the respective independent claims. In the textile industry, yarn is fed into a textile machine at a "constant amount" or "constant tension" primarily by means of devices called yarn guides. Background technique [0002] The first generation of yarn guides consisted of mechanical elements or electronic drives, various electric motors able to feed the yarn at a speed synchronized with the working speed of the textile machine in each production step. In this way, the parameters are kept constant during the various production steps with respect to the "amount of yarn" fed during the production process, thus th...
