Definitions

  • Our present invention relates to an apparatus for the stretch-spinningof artificial silk thread and similar products in which there is provided a thread or filament guide which oscillates transversely of the moving thread or filament.
  • the filaments and/or threads issuing from the spinning vessel are passed through a guide, which is usually constructed to perform in addition the function of an acidifying means, and is cross-wound on a collecting device such as a reel or bobbin.
  • the guide being reciprocated in a path perpendicular .to that of the moving thread and/or filament distributes it in the desired manner on the col- 5* lecting device.
  • the length of the thread and/or filament is at a minimum in the mean portion of the guide and increases towards the points at which the guide changes its direction of movement.
  • the angle between the thread and/or 1 filament and the guide varies continuously during each reciprocation of the guide, and consequently the frictional resistance between the thread and/or filament and the guide is constantly changing.
  • a filament drag i and variations in tension arise in the still plastic portion of the thread and/or filament lying between the spinning and collecting device, as a consequence of which the spun thread exhibits objectionable variations in titre.
  • Another object of our present invention is to provide an improved device for distributing thread and like products on a suitable collecting device, so constructed as to maintain a constant tension thereon during spinning, that is, to provide a guide which despite its oscillatory motion will not subject the thread and/or filaments to constantly varying stresses and strains.
  • Figure l is a semi-diagrammatic perspective view of our improved device
  • Figure 2 is a similar view, but showing the use of two guides
  • Figure 3 is a detail" view showing the path traversed by a thread and/or filament when the angle of the filament with respect to the guide rod is kept constant;
  • Figure 4 is a semi-diagrammatic perspective view showing our improved thread guiding and acidifying device so arranged as to oscillate in 'a conical path;
  • Figure 5 is a similar view but showing the device so arranged a's-to oscillate in a cylindrical path
  • Figure 6 is a perspective view showing a preferred construction for guiding means, to be osci1- lated in accordance with the teachings of Figure 4;
  • Figure 7 is a similar view but showing a construction for guide means to be oscillated in accordance with the teachings of Figure 5.
  • FIG 3 we have shown a stationary eye I2 positioned between the deviating rod l3 and the guide l4 along the axis AB.
  • the angle of the thread at A will In Figure 4 we have shown schematically the arrangement provided by the invention of an acid trough l5 which serves as a filament guide and oscillates in a conical path about the axis AB, so that the filament lengths and the filament angle remain constant.
  • the eye I6 is a-rranged in the modification shown in Figure 4 so as to oscillate with the filament guide I5, so that the oscillating motion of the filament places but a weak tension on the portion AA of the filament.
  • an acid guide or trough I! which serves as a thread guide and oscillates about the axis AB so that the filament lengths and the filament angles remain constant.
  • the eye 18 is arranged to oscilbeams 2
  • each acid guide be mounted on a separate member IS.
  • the threads 24 issuing from a conventional spinning vessel (not shown) pass around the deviating rod 25, through the eyes 26 secured to the members I9, through theacid guide troughs and onto a. suitable collecting device.
  • a stretch spinning device for the manufacture of artificial thread comprising, in combination, a'thread deviating means, a collecting means, a thread guide located therebetween and mounted for oscillatory movement perpendicular to thread passing from the deviating device to' the collecting means, means to oscillate said guide about an axis passing through the point of contact of thethread on the deviating means and on the collecting means, the path of the movement of said guide .being'such as to maintain constant during the-spinning the thread lengths and fila ment angles.
  • a stretch spinning device as claimed in claim 1, comprising means located between the thread guide and deviating means, and secured to said thread guide and positioned in alinement with the axis of movement of the guide whereby the angle between the thread and deviating means is maintained substantially constant.
  • a stretch spinning device for the manufacture of artificial thread comprising, in combination, a thread deviating means, a collecting means, a thread guide contacting the thread at spaced points located therebetween mounted to oscillate about an axis passing through the point ofcontact of the thread on the deviating means and on the collecting means, means to oscillate said guide whereby the thread passing through the guiding surface will generate a portion of a cylindrical surface so that the thread lengths and filament angles remain constant during the spinnin'g operation.
  • A- stretch spinning device as claimed in claim 3, comprising means located between the thread guide and deviating means, and secured tov said thread guide and positioned in alinement with the axis of movement of the guide whereby the angle between the thread and deviating means is maintained substantially constant.
  • a stretch spinning device for the manufacture of artificial thread comprising, in combination, a thread deviating means, a collecting means, a thread guide located therebetween mounted for circular movement on an axis whose.
  • center line passes through the point of contact of the thread on the deviating means and on the collecting means, whereby the thread lengths and filament angles remain substantially constant during the winding operation, and means to move said guide.
  • a stretch spinning device as claimed in claim 5, comprising means located between the thread guide and deviating means, and secured to said thread guide and positioned in alinement with the axis of movement of the guide whereby the angle between the thread and deviating means is maintained substantially constant.
  • the step of rotating the thread guide about a circular path during spinning whereby the thread lengths and thread angles are maintained constant between the thread deviating means and receiving means.
  • a stretch spinning device for the manufacture" of artificial thread comprising, in combination, a thread deviating means, a collecting means, a thread guide contacting the thread at spaced points located therebetween mounted to rotate about an axis passing through the point of contact of the thread on the deviating means and on the collecting means, means to rotate said guide whereby the thread passing through the guiding surface will generate a cylindrical surface so that the thread lengths and filament angles remain constant during the spinning operation.
