Description

May 11, 1937. w. REINERS ET Al. 2,079,966
COP AND TUBE THEREFOR Original Filed Nov. '7, 1933 Patented May 1I, 1937 UNITED STATES PATENT OFFICE COP AND TUBE THEREFOR Wilhelm Reiners, Gladbach-Rheydt, and Gustav Kahlisch, Rheydt, Germany, assignors to W.
Schlafhorst & Co.,
Gladbach-Rheydt,
Ger-
many, a corporation of Germany November 22, 1932 1 Claim.
This invention relates to a cop tube specially adapted to retain the end of a yarn Wound thereon. In our co-pending application, Serial No. 697,056, filed November '7, 1933, now Patent No.
2,035,721, issued March 31, 1936, for improvements in and relating to Winding cops, We
have described and claimed a method of and apparatus for Winding cops. The present application is a division of the said co-pending application and claims the cop tubes.
The principal object of the invention is to provide cops which have their yarn secured against unwinding, and it is particularly advantageous for such slippery yarns as artificial silk.
The invention Will be described in greater detail with reference to the accompanying drawing, wherein:
Fig. 1 is a fragmentary side elevation of one form of cop tube in accordance with the invention;
Fig. 2 is an end elevation of the cop tube looking toward the base; and
Figs. 3 and 4. are respectively similar views of a modified form of tube.
As shown in Figs. l and 2 the cop tube comprises a tubular body 9 having a conical base I0 in the periphery of which is formed an annular notch I5. Within the notch I5 is placed a ring I6, preferably of rubber. The ring coacts with the sides of the notch I5 to form sufficiently acute clamping surfaces to hold the yarn end positively.
Figs. 3 and 4 show a modication wherein the base I I] of the tube has fixed to its butt a tubular 5 element I'I provided with an outwardly curving plate-shaped flange I8. Between the flange I8 and the butt of the tube base is a ring I9, which serves to clamp the yarn end securely.
It Will be noted that with each of the cop tubes 10 described the yarn will be clamped to the base of the tube in the process of guiding it over onto the spindle, as described in the co-pending application referred to above. The clamping means being in the form of a complete annular groove, l5 the yarn falls naturally into place in the clamping means as the tube continues to spin with the spindle. When the cop is doied from the spindle the yarn breaks Without unravelling from the cop.
We claim:
A cop tube comprising a tubular body having at one end a radially opening annular notch formed by the butt of the tube and a plateshaped member attached thereto, and an elastic 25 ring between said butt and said plate-shaped member.
