May 21, 1963 c. J. RUSSO ETAL APPARATUS FOR TREATING FIBERS 2 Sheets-Sheet 1 Original Filed Dec. 21, 1959 May 2 1963 c. J. RUSSO ETAL APPARATUS FOR TREATING FIBERS 2 Sheets-$heet 2 Original Filed Dec. 21, 1959 II-lllul'lllllv tates This invention relates to an apparatus for crimping, packaging and treating textile fibens and has for an object to provide an apparatus of the above type having novel and improved characteristics.

The nature of the invention will be better understood from the following description, taken in connection with the accompanying drawings in which a specific embodiment has been shown for purposes of illustration.

In the drawings:

FIG. 1 is a side elevation of an apparatus for unwinding the package with parts broken away to show the structure; and

FIG. 2 is a section taken on the line 22 of FIG. 1.

Referring to the drawings more in detail FIGS. 1 and 2 show the package 41 as placed on a spindle 70 for unwinding.

A friction washer 71 puts the necessary drag on the package during the unwinding operation. The tape 50 passes from the package 41 through a pigtail guide 72 thence over a tension control device 73 which smoothes out the tape for reeling, thence onto a reel 74 driven by a motor 75.

The yarn 76 from the package 41 is fed through guides 77 and 78 thence through an eye 79, carried by an arm 80 projecting through a slot 81 in a housing 82 and connected to actuate an arm 84 pivoted at 85 and adapted to actuate a micro-switch 86. The arm 84 carries at its end weights 87 which are adjustable for controlling the tension of the yarn 76. The yarn 76 passes from the eye 79 to a fixed guide 88, and to a take-up device such as a constant speed winder having a yarn package 90 driven peripherally by a constant speed driving roll 91 where it is wound onto a cone or spool to form a yarn package of the usual type.

The micro-switch 86 is connected to control the operation of the motor 75 so as to exert a pull on the tape when the tension on the yarn increases and to stop the motor 75 when the tension on the yarn decreases. in this way a substantially constant quantity of yarn is maintained at the discharge point at the bite of the tape on the package 41. As more yarn is pulled from the package the discharge point recedes into the area held compacted by the tape 50 which increases the drag on the yarn 76. This increased tension closes the microswitch momentarily and causes the motor to pull the tape and thus turn the package to advance a further quantity of the core to the discharge point. This operation continues until the entire quantity of yarn has been withdrawn from the package and wound onto a cone or other form of package.

This application is a division of lco-pending application Serial No. 861,001, filed December 21, 1959, now Patent No. 2,997,747.

What is claimed is:

1. Apparatus for extracting a yarn from a core package in which a continuous core of crimped fibers is Wound together with a separating and confining tape in successive convolutions with adjacent convolutions of said core separated by the interposed tape, comprising an unwinding spindle carrying said package and adapted to turn as the package is unwound, means withdrawing the yarn from said core as the core is exposed at a delivery point, tape feed means connected to withdraw said tape from said package for thereby exposing said core at the point of removal of said tape, drive means for said tape feed means and means responsive to variations in tension of said withdrawn yarn to control the actuation of said tape feed means for advancing said tape at a rate to maintain said yarn at a substantially constant tension.

2. Apparatus as set forth in claim 1 in which said tape is withdrawn in a path to expose said core substantially at the bite of said tape with said winding.

3. Apparatus as set forth in claim 1 in which a mo tor is connected to drive said tape feed means and said tension controlled means is adapted to energize said motor periodically for advancing said tape at the rate required to maintain said tension substantially constant.

Claims (1)

1. APPARATUS FOR EXTRACTING A YARN FROM A CORE PACKAGE IN WHICH A CONTINUOUS CORE OF CRIMPED FIBERS IS WOUND TOGETHER WITH A SEPARATING AND CONFINING TAPE IN SUCCESSIVE CONVOLUTIONS WITH ADJACENT CONVOLUTIONS OF SAID CORE SEPARATED BY THE INTERPOSED TAPE, COMPRISING AN UNWINDING SPINDLE CARRYING SAID PACKAGE AND ADAPTED TO TURN AS THE PACKAGE IS UNWOUND, MEANS WITHDRAWING THE YARN FROM SAID CORE AS THE CORE IS EXPOSED AT A DELIVERY POINT, TAPE FEED MEANS CONNECTED TO WITHDRAW SAID TAPE FROM SAID PACKAGE FOR THEREBY EXPOSING SAID CORE AT THE POINT OF REMOVAL OF SAID TAPE, DRIVE MEANS FOR SAID TAPE FEED MEANS AND MEANS RESPONSIVE TO VARIATIONS IN TENSION OF SAID WITHDRAWN YARN TO CONTROL THE ACTUATION OF SAID TAPE FEED MEANS FOR ADVANCING SAID TAPE AT A RATE TO MAINTAIN SAID YARN AT A SUBSTANTIALLY CONSTANT TENSION.
