Abstract

The invention relates to the field of the textile industry and relates to a device for winding thread-like material on a forging, preferably on a spinning machine. The purpose of the invention is to improve the quality of winding. The device comprises a winding shaft 2 for rotating the package 3 and a yarn guide 4. The means for ensuring the tension and speed of the thread has a flat cam 5 with a convex working surface and a thread guide 6 rigidly connected to the yarn spreader 4. The thread guide is made in the form of plates with a transverse groove located parallel to the plane of the cam 5. The presence of the yarn feeder 6 located in the immediate vicinity of the cam ensures precise movement of the thread along the working surface of the cam, which allows for increased p vnomernost yarn tension. 1 il.

The invention relates to the textile industry, in particular, to devices for winding filamentary material on the package mainly on a spinning machine. The purpose of the invention is to improve the quality of the winding.

i The drawing shows a device for winding a filament material. : The device contains feed rolls 1, a reel shaft 2 for rotating the package 3, contacting the side surface with a moral shaft, and a folder spreader 4 installed with the possibility of reciprocating (posterior movement along the winding shaft. The reeling device also | : will provide a means for ensuring constant tension and speed of the thread-like Material, which is fixedly positioned between the feed rollers 1 and the Jiter of 4, a flat cam 5 with a curvilinear working surface in the middle part and tevoditel b, usta- | placed at the end of the rocker arm 7, rigidly attached to the yarn stacker 4. The yarn 6 is made in the form of a plate located between the yarn guide and the Flat cam parallel to the latter, and the yoke 6 is installed in close proximity to the jaw 5. In the upper iiacTH, the yarn feeder has a slot for the yarn , Perpendicular to the axis of the winding shaft, and the side surfaces of the yarn feeder 6 have bevels for interacting with the thread during threading.

I The device works as follows. : The yarn coming from the feed rolls-1 bends around the flat cam 5, passes through the groove of the yarn feeder 6 and is fed to the wrapper 4 on the package 3. The pack-3 is rotated due to friction interaction with the winder room 2. Due to the return -accessible

displacing the thread-breaker according to a given pattern, a package of the desired structure is formed. The flat cam 5 ensures that, at any position of the folder, the yarn length from the feed rollers to the point of entry of the thread to the package. The presence of the yarn feeder 6, rigidly connected to the yarn spreader 4 by the rocker arm 7 and made in the form of a plate parallel to the cam, ensures accurate movement of the thread along the working surface of the cam. This is especially important at the moments when the direction of movement of the folder stacker changes, when the yarn angle changes. The presence of beveled side surfaces on the thread guide allows for self-refilling of the thread into the groove of the thread guide 6.

The proposed device makes it possible to increase the uniformity of tension and the speed of the thread and, accordingly, the quality of the wrapped packages.
