Abstract
Abstract A device for twisting natural and synthetic fibre yarns together into a single thread, comprising a double-twist receiving spindle made vertical with a horizontal winding drum; a cabling bath with an impregnating fluid mounted under said receiving spindle; and double-twist delivery spindles mounted under the bath so that the axes of rotation of their disks are disposed in different planes passing through the axis of rotation of the receiving spindle''s disk, and each of these axes is equally spaced from said axis of rotation.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
242 words
An apparatus for twisting natural and synthetic fibre yarns into a single thread and impregnating the twisted thread for thermal stabilization thereof, comprising a vertical double-twist receiving spindle for the final twisting of the thread and winding the thread to a bobbin; a horizontal driver-type winding drum coupled to said receiving spindle to wind the thread after final twisting to said bobbin; capstan means secured above said winding drum and intended for small stretching and equalizing the structure of the thread and disposed to control a pre-determined tension of the thread before winding onto said winding drum; a first rotation disk mounted on said vertical double-twist receiving spindle and having an axis of rotation coaxial therewith; a cabling bath having an impregnating fluid and disposed under said vertical double-twist receiving spindle; hoizontal guide rods fixed in said bath and passed about by the moving yarn; each said guide rod having means to prevent the yarn from slipping off; a plurality of vertical double-twist delivery spindles mounted under said bath and additional rotation disks mounted coaxially with said delivery spindles, each of which has its axis of rotation; each said axis of rotation of the delivery spindles being in different planes passing through the axis of rotation of said first rotation disk and being at equal distances therefrom; said plurality of vertical double-twist delivery spindles providing for preparatory or additional twisting of the yarns being unwound from the bobbins installed on these spindles.

Claim 3
Dependent Claim
71 words
The apparatus as claimed in claim 1, wherein said horizontal guide rods equal the number of said delivery spindles, and each said guide rod has its ends equidistant from the axis of rotation of a respective of said additional rotation disks and wherein each said guide rod is disposed between the axis of rotation of said receiving spindle and an axis of rotation of a respective of said additional rotation disks.
