MoBE-QG- ATTORNEY3 3,079,955 TERRY SELVAGE FILLING HOLDER AND NEhTHGD Ivar 0. Moherg, Spray, N.C., assignor to Fielder-est Mills, Inc., Spray, N.C., a corporation of Delaware Filed Nov. 10, 1960, Ser. No. 68,382 7 Claims. (Cl. 139195) This invention relates to looms for weaving terry fabrics and more particularly to filling holders for terry looms for aiding in the production of an even pile throughout the width of the portion of the fabrics which is provided with terry pile.
A terry loom usually employs two sets of warp threads, "ground warps for making the body of the fabric and terry warps for making the loops or pile. In forming the loops or pile, it is the usual practice to partially beat up the filling for a series of picks, known as loose picks and designated as first, second, third, etc., depending upon their sequential insertion into the fabric. After the loose picks are inserted, it is the practice to fully beat up the filling upon the succeeding pick, known as a fast pick, which forces the loose picks against the fell of the fabric causing the terry warps, which are let off at the time of full beat up, to form loops projecting from either or both sides of the fabric.
Some problems have been encountered in the weaving of terry cloth, since the first loose pick which is to be partially beat up is held at the fell of the fabric at one end. To reach the partial beat-up position which is spaced from the fell, the pick angles rearwardly for a substantial distance across the fabric. Once the partial beat-up position is reached, the first loose pick extends the rest of the distance across the fabric substantially parallel to the fell. Subsequent loose picks in the series extend across across the fabric in substantial parallelism to the fell of the fabric, since they are not, during partial beat up, bound to the fell at either end thereof and present no problem.
The distance at which the first loose pick is spaced from the fell of the fabric determines the ability of the terry motion to fully take up, for pile loop formation, the amount of terry warp fed for a given height of terry loops. In order to take up the full amount of terry warp fed with each fast pick, it has been determined that the combined friction of three picks of weft (two loose picks and one fast pick) is required to pull the fed terry warp forward to form full pile loops on the fast pick, due to the frictional resistance of the reed, the harnesses, the drop wires and the whip roll on the terry warps. Thus, if the first loose pick extends inwardly from either selvage edge and through the shed, at an angle, for any noticeable distance, the angled portion of the first loose pick does not assist the second loose pick and the fast pick in pulling the terry warp forward through the beating up of the fast pick; that is, the angled portion of the first loose pick will not assist in pulling the pile warp forward until said angled portion is moved forward with the second loose pick. This results in short terry loops being formed on the fast pick across that portion of the fabric defined by the previously angled portion of the first loose pick, with secondary loops being formed on the respective first and second loose picks to take up the slack remaining in the terry warp. The angled portion of the first loose pick, in each instance, usually extends inwardly from the respective selvage edge of the fabric for a distance of from 1 /2 inches to 3 inches. Thus, the resultant fabric has a narrow warpwise band of pile of uneven height, from 1 /2 to 3 inches wide, along each side portion of the fabric, which is highly undesirable.
In the past, one means which was developed for achieving parallelization of the first loose pick of a terry series terry warps.
Patented Mar. 5, 1963 with the fell of the fabric comprises a pair of filling holding needles which are moved into the path of the filling by the terry motion cam and are held in the path of the filling until all of the subsequent loose picks are inserted. The filling holding needles are mounted on the temples of the loom and reciprocated therewith as the reed moves to the partial beat-up position. The needles remain descended into the warp rearwardly of the fell of the cloth at the partial beat-up position and keep the filling parallel until the insertion of the fast pick and the start of the full beat up. Before the full beat up takes place, the needle is raised out of the warp and retarded towards the front of the loom by the terry motion cam. Although this mechanism achieves parallelization of the loose picks, it is not entirely effective since it is very complicated and raises many problems in the adjustment of the complicated cams and linkages employed.
Another means which was developed for keeping the filling parallel comprises a needle which is actuated in response to the movement of the lay to either the full or partial beat-up position. The needle is moved into the path of the filling as the lay is moved rearwardly, and out of the path of the filling each time that the lay is moved forwardly. Difiiculties have been encountered in the use of this device, since the first loose pick in a terry series has a tendency to spring into the angled condition after the filling holding needle has been moved out of the path thereof which would cause the filling holding needle to move downwardly on the side of the first loose pick fartherest from the fell of the cloth. The same condition which had been encountered before the use of any filling holding means would result since the first loose pick would be in the angled condition at the time of full beat up.
It is the primary object of the present invention to provide an improved apparatus and method for holding the loose picks of a terry series in substantial parallelism with the fell of the fabric until the full beat up thereof by the fast pick.
Another object of this invention is to provide a filling holding apparatus and method in which the filling holder may be withdrawn from the warp with each beat up of the lay and will, nevertheless, always engage and parallelize respective loose pick weft during those portions of the lay movement in which the reed is spaced from the loose picks whereby the apparatus may be actuated by the action of the lay without resorting to complicated and expensive cams and linkages.
A more specific object of the present invention is to provide a simplified apparatus having a sharp-tipped or narrow-ended blade provided with a rearwardly protruding cam surface and means responsive to each rearward movement of the lay, from either the full or partial beat-up position, for moving the blade from a raised to a lowered position closely adjacent the fell of the cloth and into the path of the lose picks as they are inserted into the fabric. The cam surface engages the first loose pick upon its insertion and again, upon the insertion of any subsequent loose pick or loose picks, so that although the first loose pick may return to an angular position upon withdrawal of the blade, the cam surface engages and moves the first loose pick back into substantial parallelism with the fell of the fabric so the changing Warp shed may grip said first loose pick and insure its proper parallelism upon occurrence of the subsequent fast pick and slackening of the This produces terry loops which are of uniform or predetermined height throughout the width of the fabric.
Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which FIGURE 1 is a fragmentary side elevation of the improved filling holding apparatus in association with a 100m temple, lay and warps, with parts broken away and some parts removed for clarity;
, FIGURE ,2 is a fragmentary plan view of thenstructure shown in FIGURE 1, with portions; broken away, showing the filling holder blade in the path of the respective. first loose pick and omitting the lay;
FIGURE 3 is a fragmentary perspective. view with some portions broken away, showing the filling holder blade in the raised position out of the path of the loose pick; and.
FIGURE 4 is a fragmentary perspective view, with portions broken away, showing the filling holder blade in lowered position, wherein the first loose pick has been slid back between the warps into parallel position relation with the succeeding loose pick.
Referring now to the drawings, the embodimentiof the present invention is shown in association with a portionv of a terry loom for weaving terry fabric F formed of ground and terry warps W and wefts. Terry loops T are formed on either or bothfaces of the fabric F. The weft yarn paralle'lizing or guiding apparatus, broad- 1y designated at 10, includes a support in the form of a plate 11 suitably secured to the outer surfaceof thelefthand temple 12 adjacent theend thereof'nearest to the fell of the fabric. Plate 11 has a pair-of fixed pivot shafts 13, 14 projecting outwardly therefrom. A gear 'quadr'ant 15 is, oscillatably mounted onshaft '13- and has a plurality of teeth lfi-fth'ereon; A gear quadrant '20 is loscillatably mounted on shaft 14 and has a plurality of teeth 21'thereon in operative engagement with theteeth' 16 f on gear quadrant 15.,
Gear quadrant 20has .a downwardly projecting portion 22 ,and1anr upwardly projectingportion 23., A suitable torsionsprin'g24'is concentrically mounted on shaft14 and one end thereof is attached to a collar 14a fixed on shaft 14. The other end of torsion spring 24 is :attached to the downwardly projecting portion 22 of gear quadrant, 20 by any suitablemeans such as, a screw 25. Torsion spring 24'normally1 biases gear quadrant 20in a clockwise direction, as shown in FIGURESJ and 4, so the upwardly projecting por-tion23 engages a stop member orabutment 26 adjustably-mounted 'on plate '11.
Gear quadrant, 15 has an outwardly projecting arm 30; formed. integral therewithh Arm 36 has a filling holder. 31 adjustably attached thereto, ,by any suitable means suchfas a screw 33 for-clampingthe stemoffilling thereof which is adapted to engage the downwardly projecting'portion 22 of gear quadrant 20 to rotate gear quadrant 20 in a counterclockwise direction against the action of torsion spring 24 substantially as shown in broken lines in FIGURE 1, upon the movement of lay 40 to either the partial or full beat-up position. The foremost broken line position of FIGURE 1 is that to which arm 30 and blade 34' move with a full beat-up stroke of,lay 40;: The other broken -line position in which arm 30 and blade34 areushown: corresponds to a partial or loose. pick beat-upstroke of lay 40.
In operation, as the lay 40 moves in a backward stroke after the full beat up of a fast pick, the hunter 43 moves out of contact with the downwardly projecting portion 22. of gear quadrant 20. Torsion spring 24 rotates gear quadrant 20in a clockwise direction, as seen in FIGURE 1, until the upwardly projecting portion 23 engageslthe stop member 26. j
Gear, quadrant 20 thus rotates gear quadrant 15 in a counterclockwise direction as seen in FIGURE 1 through the teeth 16, 21. As gear quadrant 15-rotates,- the arm 30 moves the filling holder 31 carried thereby downwardly so that blade 34 enters into the path of. the sub sequently cast weft or filling; The first loose pick in the respective terry cycle is inserted with the weft A extending from the adjacent selvage edge at'the fell of the fabric, around therear-edge 36 of the filling holder blade 34, remote from the fell of the fabric'F as seen u in FIGURE 2. Lay 40 is then moved to'the partial beatup position wherein the reed 41 moves the first loose pick A to the position spaced from the fell 'of fabric F a'distance substantially equal to-twice the desired height of the loops or pile.
h'older,,,31"in aslo't ,32, formedvin the free end of arm suitable, reed cap; v42,} isv positioned rearwardly of the a apparatus 10Qand is .mounted 'onthe loom andmay be oscillated and varied in length of strokes by, a suitable variable beat-up mechanism of well known..conventional orv otherconstruction. The :lay and/or reedmove to a plurality of positions. 'The first. of these positionsisthe back position, rearwardly offthat shown .inHFIGURE l, which is the ,position at whichstheweft ,is inserted between the'warpsto form the fabric. The second of these positions is the full or normalibeat-upposition. shownrin broken linesin FIGUREil wh'ereinth'e reed 41 has moved the :inserted fillingj to the fell. of the. fabric... Another of'these positions is the partial beat-up position wherein the reed41 hasmoved the loose picks to aposition wherein.=the first loose picktis spaced from thezfell ofthe fabric adistance' approximately equalto twicetthe-desired height of the loops or pile. t Lay :40, has; a; hunter 43, mounted on. Y; the;-.fr0nt face As lay 40 is movedto the partial beat-up position,
hunter 43 engages projecting portion 22 of gear quadrant 20, rotating the gear quadrant in a counterclockwise direction; Gear quadrant 20 rotates gear quadrant- 15 in aclockwise direction, thus raising the filling holder 31 out of the path of the filling. Because of the tension in the first loose pick which is caused by'thepick' being stretched around the filling holder 31, the-first loose pick will then assume an angled condition with respect to the fell of the fabric substantially'as shown in FIGURE 3.
As lay 40 is again moved to-the back position for the insertion of the next succeeding loose pick, filling holder 31 will be moved downwardl'yin th'e'manner aforementioned." Thefilling holder is so positioned that thepoin-t 37 of'blade =34'moves against or in close-proximity to to the fell of the fabric so that point '37 of the blade 34 will enter between the warpsat a point closely adjacent the-selvage edge of the fabric and between the fell and the firstloose pick which hasassumed 'the aforementioned angled condition. The cam surface 36 of the 'blade'34 will thus engage the first loose pickand, s
as'the filling holder '31 continues its downward-movement, the-cam surface 36 will cam-the tfirst' loose pick rearwardly away from the fell of the fabric "in subs/tan tial parallelism thereto as shown'in FIGURE This action-of the filling holder 31 on the first loose pick will occur after the insertion of each succeeding loose pick, such as pick B, until the-same is fully 'beaten up' against the fell of the fabric,- thus insuring that the first-loose pick is in substantial parallelism with the fell of the'fabric at the time of full beat up. However, since the warp shed normally changes or is reversed following each'beat up of lay 40," the first loose pick A need only becammed 0r slid back following insertion of thenex tsucceedi-ng or second loose pick B, the latter picklthen vbeingheld .in substantially the desired positionflay the crossed'warps. Evenrthen, the -'blade34- is further insurance againstangular disposition of the first-loose pick A;
It. is apparent. that, since the ufirstloosepickwAis ma ntained in substantial parallelismsto .thefell of the fabric,
theiloops-or. pilepTzwillbe 'ofssu'bstantially equal height acrossxthe, full width of thesportioni of the; fabric halving terry pile thereon. It is to be noted that the novel apparatus of the instant invention is of extremely simple and compact construction which requires substantially no maintenance or adjustment. Further, since the filling holder blade 34 is moved out of the path of the filling upon each forward movement of the lay, neither the filling holder nor the reed is damaged by the movement of the reed to the partial or full beat-up positions.
It should be noted that the various movable parts in FIGURES 3 and 4 are shown in respective positions 06- cupied thereby during, and at the end of, a backward stroke of the reed 4-1 of FIGURE 1. In other words, a second loose pick has been inserted in the warp shed and beat up in FIGURE 3. Thus, the reed 41 is in the course of a backward stroke, the shed has started to reverse or change, and blade 34 has started to move downwardly in a counterclockwise direction as indicated y the arrow on quadrant arm 30. In FIGURE 4, the backward stroke of reed 4-1 and the shed change have been substantially completed, and the inclined cam surface 36 of filling holder blade 34 has entered the shed and cammed the angled portion of the first loose pick A of FIGURE 3 into parallel relation with the fell of fabric F and with the second loose pick B.
It should be noted that, while only one mechanism has been shown and described, a similar mechanism may be provided on the opposite side of the loom consisting of substantially the same structure, except that it is assembled in opposite-hand relationship. Said similar mechanism is required on any looms which weave an odd number of picks in each terry cycle, because the first loose picks of successive terry cycles are cast from opposite sides of the loom in alternation.
Although the blade 34 is spaced a short distance inwardly of the selvage edge of the fabric F, it should be noted that the remaining, relatively short, angled portion of loose pick A embraces only a narrow, plain-woven, selvage band S which, being devoid of terry loops, presents no problem.
The rear edge or cam surface 36 of blade 34 is shown as a curve, which is desirable. It is contemplated that the lower portion of cam surface 36 may be straight provided that it extends at a relatively broad, but acute,
angle relative to the front edge 35 of blade 34 or, at
least, relative to the vertical plane of the fell of the fabric F.
In the drawings and specification there has been set forth a preferred embodiment of the invention and, a1- though 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.

In a loom for weaving terry fabrics from warps and having loose picks and a fast pick inserted therein in repeated cycles, an oscillatable lay, a reed on said lay, means for moving the reed to a full beatup position wherein fast and loose picks are moved to the fell of the fabric and to a partial beat-up position wherein loose picks are moved to a point spaced from the fell of the fabric and the first of such loose picks extends inwardly at an angle from the juncture of the fell and at least one selvage of the fabric, filling holding means mounted for movement adjacent to and inwardly of said selvage into and out of the path of the first ofthe loose picks of each cycle for maintaining the first loose picks in substantial parallelism to the fell of the fabric, means responsive to each beat-up movement of the lay for moving the filling holding means out of the path of the first loose pick, and means biasing said filling holding mean into the warps during each backward stroke of the lay and, thus, into the path of the first loose pick of each cycle, said filling holding means being so arranged as to engage the first loose pick between it and the fell upon movement thereof into the path of the first loose pick after the insertion of the first loose pick and upon the insertion of subsequent loose picks of the same cycle and to move the first loose pick rearwardly in each instance into substantial parallelism with the fell of the fabric.
2. In a loom for weaving terry fabrics having loose picks and a fast pick inserted therein in repeated cycles, an oscillatable reed, and means for moving the reed to a full beat-up position wherein the fast and loose picks are moved to the fell of the fabric and to a partial beatup position wherein the loose picks are moved to a point spaced from the tell of the fabric and the first of such loose picks extends inwardly at an angle from the juncture of the fell and at least one selvage of the fabric; the combination of filling holding means mounted for movement adjacent to and inwardly of said selvage into the path of the first of said loose picks of each cycle for maintaining the first loose pick in substantial parallelism with the fell of the fabric, means responsive to each movement of the reed from each beat-up position to the next succeeding beat-up position for moving said filling holding means into and then out of the path of the first of said loose picks of each cycle, said filling holding means having a cam portion thereon adapted to engage the first loose pick between it and the fell during movement of the filling holding means into the path of the first loose pick upon subsequent insertion of at least one other loose pick of the same cycle to cam the first loose pick rearwardly into substantial parallelism with the fell of the fabric.
3. In a loom for weaving terry fabrics having warps and loose picks and a fast pick inserted in said warps in repeated cycles, an oscillatable reed, and means for moving the reed relative to the fell of the fabric to full beatup position wherein the fast and loose picks are moved to the fell of the fabric and to partial beat-up position wherein the loose picks are moved to a point spaced from the fell of the fabric and the first of such loose picks extends inwardly at an angle from the juncture of the fell and at least one selvage of the fabric; the combination of a filling holder mounted on said loom adjacent to and inwardly of said selvage for movement between a first position between the fell of the fabric and the partial beatup position of the reed in the path of the loose picks and a second position out of the path of the picks and removed from between the fell of the fabric and the partial beatup position of the reed, means biasing said filling holder toward the first position, and means responsive to each beat-up movement of the reed for moving the filling holder from the first to the second position, said filling holder having a cam surface thereon which enters the path of the loose picks between the same and the fell of the fabric and is adapted to engage the first of the loose picks in each instance and cam the same rearwardly into substantial parallelism with the fell of the fabric.
4. In a loom for weaving terry fabrics having at least two loose picks and a fast pick inserted in alternation, an oscillatable lay mounted for movement on said loom, a reed mounted on said lay for movement therewith, said loom being of a type elfecting relative movement between the fell of the fabric and the beat-up point of said reed such as to cause the reed to occupy a full beat-up position wherein the fast and loose picks are moved to the fell of the fabric and to occupy a partial beat-up position spaced from the full beat-up position wherein the loose picks are moved to a point spaced from the fell of the fabric, said reed being caused to occupy the full beat-up position only after the insertion of a fast pick and to occupy the partial beat-up position after the insertion of a loose pick; the combination therewith of a filling holder mounted on said loom adjacent to and inwardly of said selvage for movement between a first position between the fell of the fabric and the partial beat-up position of the reed in the path of the loose picks and a second position out of the path of the picks, means responsive to. the :effecting of eachifull beat-up position and-each partiaLbeat-up position of the reed for moving the/fill ingg;.holdertfrom; the-"first to 'the'second position, and. means. biasing- -said-filling holder toward thefirst position, said filling holder having a cam portion thereon pro-- vided witha narrow free endmerging with aninclined cam surface-Which enters the path oftheloose picks between thesameand the tell of the fabricl'andwhich is. adapted to engagethefirstof the loose picks in each instance: and cam the same rearwardly into substantial parallelism rwiththe fell of the-fabric.
