WINDING APPARATUS Filed Aug 2, 1960 2 Sheets-Sheet 2 INVENTOR. LOUIS A. OBERLY ATTORNEI v United States PatentO 3,097,805 WINDING APPARATUS Louis A. Oberly, Chagrin Falls, Ohio, assignor, by mesne assignments, to Midland-Ross Corporation, Cleveland, Ohio, a corporation of Ohio Filed Aug. 2, 1960, Ser. No. 47,114 2 Claims. (Cl. 242-43) This invention relates to an improvement in yarn winding apparatus and, more particularly, to a yarn laying means enabling the formation of a generally cylindrical yarn package about the core of a yarn support or of a spool.
In the collection of continuous lengths of yarn on a cylindrical core or on the core of a spool by rapid winding thereon in the form of spirals or helices laid by a reciprocating traverse, there generally will occur a yarn build-up in the form of humps at about each end of the spool or core due to a momentary hesitation upon reversal of the traverse. The resulting package is irreguiar in diameter and its full capacity is not realized, also, underwinding and entangling frequently occur. It is desirable, of course, to avoid these package irregularities since they are not economic and a low rate of winding would be necessary to avoid them.
Attempts have been made to correct the aforesaid dwell problem and some have been successful, each solution, however, being adapted to a particular type yarn and sometimes to a Winding apparatus. With the advent of greater winding speeds the problem continues to exist, especially with synthetic yarns. The improvement of this invention solves the rapid winding of synthetic monofilament yarn, such as regenerated cellulosic yarn, onto a cylindrical spool giving a final yarn package of substantially equal diameter throughout its length.
It has been heretofore generally difficult to properly wind a synthetic monofilament yarn, even more so a large denier monofilament yarn of about 450 to 900 having a nominal twist or no twist at all, into a tight cylindrical package of uniform diameter. Monofila-ment yarn of the size mentioned is straw-like in character and available winders were found not suitable for such yarn since a build-up at the package ends would occur. This condition was advantageously corrected by the present improvement, in the provision of a traversing member having regulated pivoting of the yarn laying guide, particularly at the reversal points. The controlled pivoting is efiected by means of a flexible device carried by the traversing member. The pivoted yarn laying guide is urged forwardly beyond its normal position when it approaches a reversal point and upon reversal, it is quickly brought back to a normal axially parallel position relative to the spool until it reaches a similar point at the other end of its travel. This controlled, advanced laying of yarn provides for tightly laid package ends having a diameter equal to the main body portion of the package.
More particularly, the pivoting of the yarn laying guide is desirably controlled by a leaf spring in cooperation with adjustable stops positioned at about either end of the traverse motion. With the yarn laying guide advanced beyond its normal position yarn is laid in less concentration with no momentary stop in the reversal areas providing for a monofilament package of equal diameter and of substantially equivalent density throughout. The improvement in the winding apparatus will be described in greater detail in the following specification taken in connection with the accompanied drawing, where:
FIGURE 1 is a perspective view of a portion of a winding apparatus showing the pivoted yarn laying guide and traversing member at about the end of a package;
3,097,805 Patented July 16, 1963 "ice FIGURE 2 is similar to FIGURE 1 with the yarn laying guide in a normal axially parallel position relative to the yarn package;
FIGURE 3 is a similar showing with the yarn laying guide at about the other extreme package position;
FIGURE 4 is a cross section of FIGURE 2 taken along lines 4-4; and,
FIGURE 5 is a partial cross section of the yarn lying guide of FIGURE 4 taken across lines 5-5 showing the controlling leaf spring of the yarn laying guide of the apparatus.
In FIGURES 1 to 3 of the drawing, a spindle :10 supports a spool 11 on which a monofilament yarn 12 is Wound in spirals or helices laid thereon by the reciprocated yarn laying wheel 17 rotatably mounted on the traversing member or carrier slide 1'5 positioned in the traverse support 14. The traverse support 14 is slotted and in which slot the carrier slide 15supporting the yarn lying means 17 is reciprocated. The reciprocating means efiecting the back and forth motion are well-known and are not herein described or shown.
The carrier 15 supports thereon a frame or base 20 pivoted for rotation within predetermined limits about stud or bolt 21 secured inits base. The base 20 in turn, supports in upright elements grooved thread conducting and laying rollers 16, -17 suitably positioned and rotating about supporting shafts 18 and 19. Also, there is mounted on the pivoted base 20* a U-section with its pair of parallel vertically positioned arms 24- being slotted to secure therein one end of a leaf spring 23. The leaf spring 23 is pinched in position in the slots. Since the vertical sections or arms 24 are secured to the pivoted base 20 the leaf spring 23 is adapted to be flexed whenever the base is rotated or pivoted.
On the reciprocating carrier base 15 there is also supported an undercut block 26 being secured against displacement by means of a screw or stud 27. The block 26 by being undercut permits the support 20 to move within this cut portion Within its width limits and, thus, prevent any dislodgment of the pivoting base 20 because of possible loosening of the guide supporting apparatus during traversing motions.
On the traverse support frame 14 there are provided adjustable limit stops 28, 29 positioned at a predetermined distance apart. These stops 28, 29 are contacted by an angular extension 30 forming part of the pivoted support base 20. Upon reciprocation of the yarn lying guide carrier 15 the base extension 30* abuts either guide 28, 29 effecting the pivoting of the base 20' and of the yarn laying guide wheels 16, 17 causing the yarn laying guide 17 to advance beyond its would-be normal position and, upon instant reversal, quickly retracting the yarn laying guide 17 to a normal yarn laying position.
In FIGURE 1 the yarn guide 17 is shown in a position tilted toward the left end of the yarn laying spool 11 while in FIGURES 2 and 3 the yarn laying guide :17 is normal to the spool, and it is shown as shifted to the right end of the spool 11. The leaf spring 23 normally controlling the parallel position of the yarn laying wheel 17 yields upon contact of the angular extension 30 with either limit 28, 29 to permit the yarn guide 17 to lay yarn in advance of its normal position when it quickly returns upon loss of contact with either stop 28, 29 to such normal axial yarn laying position as shown in FIGURE 2. The extended laying of the monofilament yarn and elimination of the temporary rest upon reversal prevents a build-up at the spool ends.
FIGURES 4 and 5 show in greater detail the two spaced yarn guiding and laying wheels 16 and 17 and their support on the pivoted slide support 20. Wheel 16 advantageously guides the yarn to the laying guide 17 being positioned in spaced relation thereto to provide the necessary distance therebetween giving necessary angularity to the wheel 17 when pivoted over a predetermined arc, which pivoting is resisted from a normal position by the leaf .spring 23. The pivot bolt 21 extends through the traverse support frame 14 into and through carrier slide member 15. Carrier slide member 1'5 is connected by a vertical connecting portion 33 to the reciprocating means generally designated by the partially threaded (partially shown) actuating bar or rod 34. It is fixed thereto by positioning nuts 35. The leaf spring 23 is securely held by the slotted U shaped member 24 at one end while the other end is slidable in the spaced slotted element 25. When flexed the leaf spring 23 moves in the element 25. Instead of grooved rollers or wheels '16, 17 a metallic yarn guide with or without a ceramic insert can be as readily used for the laying of yarn 12 on the spool 11. Obviously the leaf spring 23, while preferred, can be supplanted by a coiled unit. The presently described assembly is one based on economy and a minimum number of parts advantageously providing for prolonged rugged operation.
