ATTORNEYS 24 HOME-R W. Gnaoce- United States Patent TEXTILE CARD AND LAP FEEDING MEANS Homer W. Grace, Lyman, S.C., assignor to Wellman Industries, Inc., Johnsonville, S.C., a corporation of Delaware Filed Sept. 7, 1966, Ser. No. 577,648 Int. Cl. D01g /40 US. Cl. 19-105 4 Claims ABSTRACT OF THE DISCLOSURE A subframe adapted to be matingly aligned with the frame of a card for supporting a plurality of laps and for advancing the laps to the feed rolls of the card in timed relation thereto and wherein the subframe has retractable Wheels for facilitating movement of the subframe into aligned position with the card frame and for rolling the subframe away from the card frame for obtaining free access to the card feed rolls for facilitating adjustment thereof.

This invention relates to a textile card and the combination therewith of means for facilitating the feeding of textile material from lap packages to the fiber working instrumentalities of the card.

The usual procedure for preparation of textile fiber material, such as cotton and many synthetics, for the manufacture' of textile goods therefrom includes processing of the textile materials through a textile card. In such processing, the materials are conventionally supplied to a card in the form of a lap, or convolute wound package of a web or sheet of fibers about a rod known as a lap pin. Heretofore, with conventional cards processing material at production speeds below pounds per hour, traditional approaches to supplying textile material from laps to such a card have proved entirely satisfactory.

The traditional feeding arrangement for a textile card uses a pair of cradle rolls positioned immediately adjacent a pair of feed rolls which advance textile materials from a lap to the licker-in roll for subsequent processing by the main cylinder of the card and the other fiber working instrumentalities. A lap is received on and supported by the cradle rolls while rotated thereby to unwind the web of material and thus feed the material to the feed rolls of the card. With the now available capability of substantially increased production speed, in terms of pounds per hour, a single lap supported by cradle rolls cannot be relied upon to provide the high weights required without frequent replenishment. The necessity of such frequent attention by an operator tends to nullify, in part, the advantage which is obtained by the improvements in card operation, thus making a multiple lap feeding arrangement desirable. Additionally, a multiple lap feed is desirable as facilitating blending of fibers at the card.

A frequently encountered difficulty in the preparation of textile materials in a card is the inclusion of foreign matter in a web of material advanced from a lap through the feed rolls to the fiber working instrumentalities of the card. With the passage of foreign objects between the rolls, the spacing between the rolls at their nip is disturbed, and the rolls must be adjusted to return them to the desired position. Where a cradle roll lap feed is used, access for adjustment is readily obtained at any time that no lap is in position for feeding. With the increased production speed now possible, this problem presents an increased difficulty, as it may be anticipated to be encountered at more frequent intervals, and thus it is desirable that a multiple lap feeding arrangement include provision for access to the feed rolls of the associated card.

In providing for access to the feed rolls for adjustment,

it is necessary to assure continued return of the members 3,443,286 Patented May 13, 1969 of the combination to the proper operative positions if such are in any way disturbed. Thus, any multiple lap feeding arrangement wherein access for adjustment is accomplished by temporary separation of members of the combination desirably includes some means for returning the members to proper operative alignment.

With the foregoing in mind, it is an object of the present invention to provide, in combination with a textile card, means for facilitating the supplying of webs of textile fiber material to the feed rolls of the card from a plurality of laps, while readily permitting access to the feed rolls for adjustment when such is required.

In accomplishing this object, this invention provides a subframe adapted to cooperate With the frame of the card and to provide a support for a plurality of laps, a means to advance the webs of textile material from the laps to the feed rolls of the card, and a means permitting ready removal of the subframe from its operating position in conjunction with the card to permit access for adjustment of the feed roll and accurate return of the subframe to the proper operative position.

Some of the objects and advantages of the invention having been stated, others will appear as the description proceeds, when taken in connection with the accompanying drawings, in which:

FIGURE 1 is a perspective view of a textile card and lap feeding means in accordance with this invention;

FIGURE 2 is an enlarged scale elevation view, in section, of a portion of the apparatus of FIGURE 1;

FIGURE 3 is a partial section view, taken as indicated by the line 3-3 in FIGURE 2;

FIGURE 4 is a plan view, in partial section, taken as indicated by the line 4-4 in FIGURE 2; and

FIGURE 5 is an enlarged scale perspective View, in partial section, of a portion of the apparatus of FIG- URES 1-4.

Referring now more particular to the drawing, a high production textile card is there shown and indicated generally at 10 (FIGURE 1). The card 10 includes, as is conventional, a frame supporting the operating instrumentalities of the card and including a rearward portion 11 on which a licker-in cylinder 4 and

feed rolls

15 and 16 are supported (FIGURE 2). Other fiber working operating instrumentalities are provided for the card 10 as is conventional, such as a main cylinder and moving flats, and a card drive is included to properly drive the operating instrumentalities of the card 10, including the 1iekerin 14 and the

feed rolls

15 and 16, in rotation.

In order to accommodate a plurality of laps, and thus supply textile materials for processing at the rate required :by the high production of the card 10 without requiring frequent attention, this invention contemplates the combination with the card of a supply means indicated generally at 18, which includes a subframe indicated generally at 20 and particularly adapted for cooperation with the rearward portion 11 0f the frame of the card 10, as described more fully hereinafter.

Preferably, the subframe 20 comprises two

side plates

21 and 22, each having a pair of depending legs. Each of the depending legs is provided with a leveling jack (FIG- URES 1 and 3), in the form of a foot 24 which is vertically adjustable relative to the respective depending leg of the

side plates

21 and 22, with the relative vertical displacement between a foot and the associated leg being determined by an adjustment means such as a bolt 25.

In order to support a plurality of lap pins and the laps wound thereabout, the supply means 18 of this invention includes vertically upstanding guide means in the form of four lap guide standards 26, two secured to each of the

side plates

21 and 22 of the subframe 20 and extending upwardly therefrom (FIGURES 1 and 2). Each of the standards 26 has a central longitudinal opening or slot therein, for receiving lap pins about which laps are wound, and is of sufficient lateral width to engage the end of a lap so that each cooperating pair determine the lateral or sideways position of the lap positioned thereby with respect to the card 10. Preferably, the standards 26 are of sufficient height so that each pair will receive and accommodate a pair of overlying or stacked laps, thus mak ing possible the supply of material to the card from four laps in all. However, it is contemplated that the standards 26 may be of reduced height so that each cooperating pair will receive and position a single lap, where the material being processed does not require a supply rate necessitating a four-lap feed.

In order to advance textile material from the laps positioned by the standards 26 to the

feed rolls

15, 16 and thence to the fiber working instrumentalities of the card 10, my invention provides an endless, flexible member 30 which underlies and supports the laps positioned by the standards 26 and advance the web of textile fiber material from those laps to the card 10 (FIGURE 2). Preferably, the member 30 is a conveyor belt having a predetermined width substantially the same as the width of the laps and as the width of the card 10, and is supported for movement along a predetermined closed path of travel including a substantially horizontal reach which is substantially aligned with the feed rolls and 16 by a pair of

support rollers

31, 32. The horizontal reach is traversed by an upper run of the conveyor member 30, on which the laps positioned by the standards 26 are received. Each of the

rollers

31 and 32 is secured to a respective shaft 34, 35 and supported for rotation by respective bearing means 36, 37 mounted on the

side plates

21 and 22 of the subframe 20. One of the supporting rollers, preferably the roller 32, in interconnected to the card drive arrangement which rotatably drives the

feed rolls

15, 16, as by a gear 38 secured to the respective roller shaft 35 and engaging a gear 39 in the card drive train (FIGURE 1).

In order to assure proper feeding of the web of textile fiber material from the laps resting on the member 30 to the

feed rolls

15, 16 of the card 10, my invention provides a rigid platform 40, underlying the upper run of the conveyor member 30. The supporting platform 40 preferably is formed of sheet steel or similar material, and has depending side portions which are secured to the upper extremities of the

side plates

21 and 22 of the subframe 20. This platform 40 prevents downward sag of the member 30, and thus precludes crinkling or rippling of the web of textile material as the same is advanced to the

feed rolls

15, 16.

In order to permit obtaining access to the

feed rolls

15, 16 of the card 10, for adjustment of those feed rolls in the event a foreign object passes therethrough and forces the rolls apart or upon the occasion of a change in the textile material being processed, my invention provides wheeled jack means for raising and lowering the supply means 18 and for permitting rolling movement of the subframe away from the frame of the card 10 while in the raised position. The jack means takes the form of a plurality of casters 41 (FIGURES 2-4) mounted for controlled unison movement between a frame supporting position and a position in which the frame rests upon the feet 24 (FIGURE 2). Each of the casters 41 is mounted on a respective carrier plate 42, which in turn is secured to one of a pair of rocking shafts 44. Each of the shafts 44 is rotatably supported from the subframe 20 by a plurality of bearings 45, secured to frame cross-members 46. A control arm 48 is also fixed to each of the shafts 44, centrally of the subframe 20. The control arms 48, connected to the two shafts 44, are engaged by respective lateral projections 49 extending from a jack rod 50, which extends lengthwise of the frame 20. One end of the jack rod 50 (FIGURE 4) has a threaded lateral projection 51 thereon, which is penetrated by a jack screw 52. The jack screw 52 is adapted to be engaged by a crank handle 53, and rotated to move the jack rod 50 laterally. Upon movement to the left in FIGURE 2, the lateral projections 49 engage the arms 48 and cause unison rotational movement of the shafts 44, pivoting the casters 41 downwardly into engagement with the floor surface 54 on which the supply means 18 and card 10 are supported and thus raising the subframe 20 and permitting rolling movement thereof away from the associated card 10, to provide access to the

feed rolls

15, 16 for adjustment thereof.

In order to assure proper relative location of the subframe 20 with regard to the frame of the card 10 subsequent to adjustment of the

feed rolls

15, 16 and as the supply means 18 is returned to an operating position, this invention provides alignment guide means on the subframe for cooperating with the card frame to assure correct placement of the member 30 relative to the feed rolls 15 and 16 (FIGURE 5). The alignment means comprises a cam-like projection on one of the frame members of the card 10 and the supply means 18 and a mating cavity on the other frame, with the cavity and projection cooperating during placement of the supply means into operating position to assure proper alignment of the supply means. Preferably, the cavity 60 is formed in one of the frame members, such as the

side plate

21 and 22 of the subframe 20, during the original manufacture of the frame member, and is of part cylindrical configuration. Upon initial installation of the supply means 18 in combination with the card 10, scribe marks are drawn on the abutted face of the rearward portion 11 of the card frame and a cam-like half-round bar 61 of suitable material such as brass is positioned for proper engagement of the cavity 60. The bar 61 is then secured in place as by bolting to the card frame. Thereafter, upon removal of the supply means 18 from the operating position adjacent the card 10, the mating engagement of the half-round bar 61 and the cavity 60 upon return of the supply means 18 to the operating position assures proper alignment of the endless, flexible member 30 with respect to the

feed rolls

15 and 16, so that textile fiber material from the laps supported on the supply means is properly advanced to and through the feed rolls.

In the drawing and specification, there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.
