Definitions

  • This invention relates to improvements in textile appliances, and in particular to appliances adapted to facilitate the unwinding of threads from bobbins and like packages.
  • the object of the invention is to provide a device which will enable such over-end unwinding of threads to take place with the greatest regularity possible.
  • the thread on passing over the end or" the package isconstrained by guide means to follow a circular path about the axis of the package, and prior to engagement by the guide means is passed through a tensioning device which tends, e. g'. by spring action, to draw the thread substantially radially towards the axis of the package to a greater or less degree in accordance with the variation in tension of the thread as it leaves the package.
  • the tension of the thread in unwinding opposes the substantially radial action of its tensioning device, so that the combined action of the two serves to allow the thread to be drawn smoothly from the package.
  • the means serving to guide the thread in a circular path about the axis of the package may preferably comprise a circular guide edge round which the thread can move during unwinding.
  • the guiding edge may be constituted by a member which isfree to rotate about the axis of the package under the action of the unwinding thread.
  • An additional circular guide edge, whether revolving or not, may also be provided immediately over the package from which the thread is drawn, and may, .for example, consist of a burnished metal cap provided on the upper flange of the package support.
  • additional tensioning devices and circular guide edges may be provided in series with the first to multiply the effect obtained. I
  • the tensioning device is provided with a spring of suitable strength to resist the outward pull of the thread passing from the package to the guiding device.
  • the tensioning member consists of a guide eye mounted on a spiral spring carried by a ring which is free to move about the axis of the package.
  • the action of the tensioning device can be made very delicate by suitable choice of the length of the spring. In general, it is sufiicient to make the'spring of such length that in extending from the central supporting ring to the guide eye it makes from one-half to one complete turn about the axis of the package.
  • FIG 2 is a sectional plan of the driving mechanism in the spindle shown in Figure 1,
  • the bobbin 5 is provided with a burnished brass cap 20 over its upper flange 21, while down the axis of the bobbin, inside the spindle 6, passes a tube 22, fltting into blocks 23 inside the tube 6 and supported by means of a spring 24.
  • An annular member 25 secured near the top of the tube 22 carries a brass disc 26 with a burnished edge and beneath the disc 26, lying in an annular groove in the member 25 is a light ring 27.
  • the ring 27 carries a spiral spring 28 which terminates in an eye 29 clearly shown in Figure 2. If desired the ring 27 may be formed by curving upon itself the inner end of the spring 28, and in a similar manner as shown in Figure 3 the eye 29 may be made by twisting the free end of the spring 23.
  • Thread tensioning means for use in the over-end unwinding of threads from packages, comprising a circular guide edge to constrain the thread to pass through a point which follows a circular path about the axis of the package, and a spiral spring twisted at its free end in the form of a guide eye through which the thread passes prior to its engagement with the said guide edge, said spring tending to draw the thread substantially radially inwards towards the axis of the package in accordance with the tension in the thread as it leaves the package.
