` 7 Claims. v (131.2427118) Our present invention has to do with a new and novel spool for use in the wet-treatment and drying of filaments. I, l V One object of the present y,invention is to pro- 5 vide a collapsible spool which aids in the production'of laments with a more even shrinkage. Another object is to provide a collapsible spool which may be rotated'horizontally and used as a take-up spool. V In the manufacture of artificial filaments by the wet spinning process, for example, from a viscose solution, the formed filaments pass from a setting or precipitating bath to a spool upon which they are wolmd. These spools are usually cylindrical and perforated in order that a pres-- sure or vacuum washing process may be followed. The filaments while on this spool are deacidied; desulphurized, bleached, washed, and dried. Usually, in drying on a rigid spool, great differiences in `shrinkage between the inner and outer layers of the laments result. -In order to overcome this unevenness of shrinkage resulting from 'a rigid spool, collapsible spoolsmay be employed at this point ofthe process. The present invention; concerning such a type of spool is described as follows: r Y
After the rst drying operation on the original spinning., spools' it' is usually Anecessary to twist the yarn thereon. During the twisting operation the yarn is naturally transferred from one spool to another, andthe outside layers of the spinning Y .-spools'are transferred to the inside of the takeup spools on the twisting machine. In order to obtain even shrinkage of the -yarn on the take-up spool, a collapsible spool as shown on the attached drawing may be employed. After the twisting operation this spool isremoved from the cylindrical spJol holder, moistened by any suitable means, and redried from the inside of -40 the spool.
As set forth in the accompanying drawing,
Figure 1 is a side elevation of the holder with the spool thereon, the outline of the yarn being shown in dotted lines,
Figure 2 is a cross-sectional view taken through Figure 1, the yarn being shown upon the spool,
Figure 3 is a view similar to that in Figure v 2, with the holder removed.
56 As shown in the drawing, the spool holder consists of a cylindrical portion 1, with a centrally located spindle 2. The central portion l is of a circumference sufficient to'v just fill the spool 3 when it is in expanded condition. As shown in the drawing, the spool 3 consists of a per-L the cake 6. When drying this cake,- the holder forated shell portion with a plurality of longitudinal slotsl S. Six slots are shown in the drawing, byway of illustration. These slots S terminate alternately in slits running to the end of the spool (4, 4', 4") and (5, 5', 5"). These slits 6o produce two sections of the spool which ,are flexed sothat they tend to overlap rather than meet one another. As shown speoiflcallyin Figure 2, the presence of the holder 1 within the spool 3 tends to keep the edges of the slits 4 65 etc., and 5 etc., so that they form meeting edges. When the holder is removed, the edges of these slits tend to overlap (Figure 3) and thus tend to reduce the circumference of the spool.
In operation, a spool of stainless steel, or some resilient and resistant metal, is used. The empty spool is placed upon the holder and the edges ci?- the slits are thereby caused to meeteach other. The filaments are then wound thereupon to form 1 is removed, and the meeting edges allowed to overlap. This reduces the circumference of the spools and allows the layers of filaments to dry properly in order that an' even shrinkage may result.
The' present spool may be used alone, as set forth, or in connection with the drying apparatus set forth in the copending application o f Thomas H. Byron and one of the present applicants, Serial Number 598,866, led March 14. 1932. 4gli Although the modification shown consists of a spool with six slots therein, we do not wish to be limited to this number. We further do not wish to be limited-to the exact modification shown, otherwise than indicated by the following claims. 9o
We claim:
1. In a collapsible spool, a perforated shell portion, a series. of slots running longitudinally of said shell, but of a length so that they do not extend the full-length of the shell portion, each of said slots terminating at the end of said shell, alternate slots terminating at alternate ends of the shell, said spool shell being of resilient material so stressed that the terminating ends tend to overlap one another rather than meet 2. In a collapsible spool, a perforated shell portion,` a series of slots running longitudinally of said shell, but of a length so that they do not extend the full length of the shell portion, each of said slots terminating at the end of said shell, said spool shell being of resilient material so stressed that the terminating ends tend to overlap one another rather than meet.
3. In a collapsble spool, a perforated shell portion, alternate slots terminating at alternateen 110 of the shell, said spool shell being of resilient material so stressed that the terminating ends tend to overlap one another rather than meet.
4.-In combination, a rigid spool holder and a perforated spool, said holder being practically the same length as th spool, and terminating in an extending lug, said spool comprising a perforated shell portion, slotted longitudinally by slots insufficient in length to extend the length of the spool, alternate slots terminating at alternate ends of the spool, said spool shell being of resilient material so stressed that the end portions defined by the slots tend to overlap, said overlapping being prevented during the winding operation because of the presence of the spool holder, the removal of the spool holder, however, causing the said end portions to overlap and thus reduce the circumference of the spool.
5. In combination, a rigid spool holder and a perforated spool, said holder being practically the same length as the spool, said spool comprising a perforated shell portion, slotted longitudinally by slots insuicient in length to extend the length of the spool, alternate slots terminating at alternate ends of the spool, said spool shell being of resilient material so stressed that the end portions defined by the slots tend to overlap.
6. In combination, a rigid spool holder and a tions defined by the slots tend to overlap, said overlapping being prevented during the winding operation because of the presence of the spool holder.
'7. In combination, a rigid spool holder and a perforated spool, said holder being practically the same lengthl as the spool, said spool comprising a perforated shell portion, slotted longitudinally by slots insuflicient in length to extend the length of the spool, alternate slots terminating at alternate ends of the spool, said spool shell being of resilient material so stressed that the end portions dened by the slots tend to overlap, said overlapping being prevented during the winding operation because of the presence of the spool holder, the removal of the spool holder, however, causing the said end portions to overlap and thus reduce the circumference of the spooLl RICHARD ELSSNER.
