[57] ABSTRACT To avoid damage to terry loops formed on that portion of terry cloth which passes through a temple during weaving on the type of terry loom whose cloth is shifted forwardly and backwardly in alternation incident to forming the terry loops, the temple is shifted forwardly and rearwardly with the cloth solely by transmitting such movement directly from the cloth to the temple so there is essentially no relative movement between the cloth and the temple during terry weaving other than the normal takeup of the cloth.

sum 2 [1F 2 TEMPLE FOR TERRY LOOMS AND METHOD OF OPERATING SAME For many years terry cloth has been woven on fly shuttle looms by shifting the reed between partial and full beat-up positions during oscillation thereof to form loose picks and fast picks incident to the formation of terry loops in the cloth. Although it has also been known for many years to shift the cloth forwardly and rearwardly in alternation relative to the beat-up point of an oscillating reed instead of shifting the reed per se to form terry loops, the technique of shifting the cloth has come into more widespread use only recently; i.e., with the more widespread use of shuttleless terry looms, because the technique of shifting the reed has presented more critical problems than that of shifting the cloth, particularly with respect to the weft inserting means used on many shuttleless looms.
As is well known, most looms are equipped with .conventional temples which engage the cloth adjacent the selvages and the fell thereof for maintaining lateral tension in the clothand thereby to maintainthe fell sub stantially straight and taut during beat-up of the reed against the fell. Such conventional temples generally have very little, if any,,warpwise movement so that, when they are used on a terry loom in which terry loops are formed by shifting thecloth forwardly and rearwardly substantial amounts, any given portionof the cloth adjacent each selvage is moved back and forth repeatedly through the corresponding temple, thus being abraded and damaged or mutilated to some extent by the temple and resulting in low quality terry cloth.
It is known to provide a warpwise movable temple which moves backand forth with cloth beingwoven on a terry loom so as to preventabrading and damaging the portion of the cloth passingthrough the temple. However, special linkages and spring means are used for imparting the warpwise, movement to such known temple, such known temple has no means for stopping the warpwise movement thereof, as 'would be necessary during plain weaving or non-terry operation of the loom, and since the known temple is moved through connections with a rotary cam, the rate of such movement might vary relative to the rate of movement of the cloth, even though the extents of such movements of the temple and the cloth might be the same.
It is therefore an object of this invention to provide an improved temple mounting means and method of operating the temple which obviates the. need for any drive means and connections thereto for moving the temple, which also obviates the need for any means for stopping warpwise movement of the temple in the transition from terry weaving intervals to non-terry intervals of loom operation, and wherein the movement of the temple for-wardly and rearwardly in unison with the cloth is ensured by transmitting such movement solely from the cloth to the temple, so that essentially the only relative movement between the temple and the cloth is effected by the normal take-up of the cloth during terry weaving.
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 FIG. 1 is a schematic view of a terry loom with the improved temple assembly thereon;
FIG. 2 is an enlarged perspective view of the temple assembly adjacent one side of the loom and showing a typical weft tucking needle adjacent the warp shed;
FIGS. 3 and 4 are side elevations, partially in section, taken substantially along the line 33 in FIG. 2 and showing the temple in respective loose pick and fast pick positions;
FIG. 5 is a fragmentary vertical sectional view taken substantially along line 5-5 in FIG 2; and
FIG. 6 is a plan view of the temple assembly.
The temple assembly of this invention may be used in association with any terry loom of the type wherein each terry cycle is effected by shifting the cloth and warps forwardly about 3/16 to inch from a normal position to an abnormal position and then shifting the ground warps and the cloth back. to the normal position. In other words, the fell of the cloth is spaced forwardly of the beat-up point of the reed during insertion and beat-up of two or more loose picks of weft and the fell occupies a fast pick position or normal position corresponding to the beat-up point of the reed during insertion and beat-up of a fast pick of weft to form a corresponding transverse row of terry loops projecting upwardly and/or downwardly from the base of the cloth. By way of example, the loom may be of a type disclosed in a copending application of Douglas P. Burgess et al., Ser. No. 834,716, filed June 19, 1969, and entitled GROUND WARP SHIFTING MEANS FOR TERRY LOOMS, which will issue as US. Pat. No. 3,570,547 dated Mar. 16, 1971, and the disclosure of which isincorporated herein by reference.
Referring more specifically to the drawings, the loom includes shed forming means or heddles 10 and an oscillatable reed 11 through which ground warps 12 and terry warps 13 are directed from respective sources, such as warp beams 12a, 13a. Warps 13, 14 extend to the fell of cloth 15 which passes over and is taken up by a take-up roll 16 to which normal incremerits of rotation are imparted by suitable take-up means 17 to take up the cloth the equivalent of one pick during each oscillation of reed 11 Any suitable means may be used for shifting the cloth 15 and ground warps 12 forwardly and rearwardly between the aforementioned normal and abnormal positions during terry weaving. As shown, take-up roll 16 is rocked about its axis by a rocking device generally designated at 20 and which may be of the type disclosed in said copending application. Rocking device '20 includes a rocker arm 21 operatively connected to take-up roll 16 through means, not shown, and which arm is connected by linkage 22 to a cam follower lever 23 pivoted at 24 on the loom frame. A follower 25 on lever 23 engages a rotary terry cam 26.
Each time the low surface of terry cam 26 moves into engagement with follower 25, it imparts clockwise movement to rocker arm 21 (FIG. 1) and thereby imparts corresponding angular motion to cloth take-up roll 16 to advance the cloth about .3/ 16 to k inch, depending upon the desired length of terry loops to be formed. Conversely, whenever the high surface of terry cam 26 moves into engagement with follower 25, rearward angular motion is imparted to cloth take-up roll 16 to return the fell of the cloth 15 to the beat-up point of reed 11 as the ground warps 12 are pulled rearwardly relative to the terry warps 13 by a roll 27 over which the ground warps 12 pass in their course from beam 12a to heddles 10.
Roll 27 is rotatably supported by shifting levers 30, only one of which is shown. The lower portion of shifting lever 30 is pivotally mounted on the loom frame, as at 31, and lever 30 is pivotally connected to follower lever 23 by a link 32. Thus, each time the cloth is moved forwardly by the angular motion of take-up roll 16, terry cam 26 also imparts forward movement to roll 27 to permit the ground warps 12 to be moved forwardly with the cloth 15. Conversely, each time the take-up roll 16 is rotated in the reverse direction by cam 26, roll 27 is caused to move rearwardly to pull the ground warps l2 and the cloth 15 rearwardly and thus return the fell of the cloth to the normal beat-up point of reed 11. Conventional means may be employed for letting off a predetermined amount of the warps 13 during each forward movement of the fell of the cloth to the loose pick or abnormal position and, of course, the terry warps 13 are not moved rearwardly during each rearward movement of the cloth 15 so as to provide slack in the terry warps 13 for forming the terry loops therefrom, as is well known.
According to the invention, improved temple assemblies are provided adjacent opposite sides of the loom for engaging the cloth adjacent the fell and the longitudinal edges or selvages of the cloth for applying lateral tension thereto so as to maintain the fell substantially straight and taut during beat-up of reed l 1. Only one of the temple assemblies are shown, but it is to be understood that a similar temple assembly would be provided adjacent the opposite side of the loom. As best shown in FIGS. 2-6, the temple assembly comprises a temple broadly designated at 40 which, per se, may be of conventional or other construction. As shown, temple 40 comprises an elongate channel member or body 41 which extends weftwise with its front and rear flanges facing toward the cloth 15. The closed outer end of channel member 41 supports the outer portion of a burr roll 42 positioned between the flanges of channel member 41 and having a plurality of freely rotatable burr rings 43 thereon whose burrs or pins are engaged by the outer portion of the cloth 15. The cloth 15 is looped partially around burr roll 42 and engages the free lower edges of the flanges of channel member 41, which flanges ensure that the burr rings 43 will penetrate and apply lateral tension to the cloth. Although only a single burr roll 42 is shown, it is well known that temples may include two or more burr rolls arranged therein in a well known manner. Also, although channel member 41 is shown positioned above the cloth in FIGS. 2, 3, 4, and 5, as is usually the case with respect to some looms, such as a Sulzer" loom, it is to be understood that the channel member 41 may be positioned beneath the cloth 15 with the cloth then passing beneath the burr roll 42 as is the case with some other looms, such as a Draper DSL shuttleless loom, for example.
Conventional temples generally have very little, if any, warpwise movement so that, when they are used on a terry loom in which loops are formed by shifting the cloth forwardly and rearwardly substantial amounts, any given portion of the cloth adjacent each side longitudinal edge thereof is moved back and forth repeatedly through the corresponding temple, thus being abraded, damaged or mutilated to some extent by the temple and resulting in a low quality terry cloth. Therefore, according to the method of this invention, the temple is shifted forwardly and rearwardly with the cloth solely by transmitting the forward and rearward movement of the cloth incident to the terry cycles of the loom directly to the temple during each terry cycle of the loom so that there is practically no relative movement attendant to the shifting of the cloth between the aforementioned normal and abnormal positions other than that of the normal take-up of the cloth the equivalent of one pick during each oscillation of reed 11. To this end, means are provided for supporting the temple 40 for substantially free forward and rearward movement with and solely by the cloth 15 during terry weaving. Such means comprises a swing arm 46 to which channel member 41 is suitably secured adjacent the outer end thereof. Swing arm 46 extends upwardly in a direction away from cloth 15, and the reduced upper portion of swing arm 46 is pivotally mounted, as at 47, in the slotted rear portion of a support bracket 50.
In order that support bracket 50 may be adjusted to vertically vary the position of temple 40 relative to the loom frame, as is desirable in order that the mean horizontal plane of the fell of the cloth 15 may be properly positioned with respect to the heddles 11, the front portion of support bracket 50 is pivotally mounted, as at 51, on a fixed part 52 of the loom frame. A medial portion of support bracket 50 has a substantially vertically disposed adjustment screw 54 threaded thereinto with the lower portion of adjustment screw 54 normally resting against a stationary member 55 carried by the loom frame. Thus, by adjusting the screw 54 downwardly and upwardly relative to support bracket 50, it is apparent that the rear portion of support bracket 50 and temple 40 will be adjusted upwardly and downwardly relative to the loom frame.
From the foregoing description, it is apparent that swing arm 46 and support bracket 50 cooperate in providing means for guiding temple 40 forwardly and rearwardly relative to support bracket 50 without encumbering such movement so that it may readily be transmitted to temple 40 directly from the cloth 15. It is desirable to limit the extent of warpwise movement of temple 40 in the forward direction because the cloth has to be taken up in normal relatively small increments by take-up roll 16 throughout operation of the loom. Also, since the rearward movement of the cloth 15 is effected very quickly, it is desirable to provide means for limiting the extent of rearward movement of temple 40 so that the momentum of each rearward movement imparted to temple 40 will not cause the rear flange of channel member 41 to move rearwardly beyond the fell of the cloth. Accordingly, the rear portion of a bar 60 is pivotally connected, as at 61, to one side of the enlarged lower portion of swing arm 46, and a forward portion of bar 60 is provided with an elongate, forwardly and rearwardly extending slot 62 therethrough which is loosely penetrated by a fixed abutment 63. Abutment 63 also engages the upper and lower walls of slot 62 and serves to guide the forward portion of bar 60 in a substantially linear path.
Stationary abutment 63 is suitably secured to support bracket 50, and its outer portion is straddled by a pair of spaced apart movable abutments in the form of front and rear adjustment screws 64, 65 which penetrate respective ears 67 on bar 60. The set screws 64, 65 may be adjusted so that, when they engage stationary abutment, in alternation, they limit the range of movement of temple 40 in accordance with the amount of warpwise movement imparted to the cloth 15. It is also desirable, but not entirely necessary, that the vertical plane of the pivotal axis 47 of the swing arm 46 is substantially midway of the normal range of warpwise movement imparted to temple 40 by the warpwise shifting of the cloth 15.
As heretofore stated, temple 40 and its support bracket 50 are substantially vertically adjustable relative to the loom frame so that the mean horizontal plane of the fell of the cloth may be properly positioned with respect to the heddles 10. As is well known, some looms, especially Sulzer looms, are equipped with a tucking needle, such as that generally indicated at 70 in FIG. 6, for bending-in or tucking-in each end of the weft thread by drawing the previously cut corresponding ends of the weft thread into the open warp shed. Such a tucking needle as that indicated at 70 is pivotally supported, as at 71, in a predetermined position relative to the frame of the loom and, consequently, any vertical adjustment of the temple 40 which would raise the adjacent portion of the fell of the cloth out of its normal optimum position with respect to the tucking needle 70 might result in the tucking needle striking and damaging or ensnaring at least some of the warps defining the lower wall of the warp shed in the course of reciprocation of the corresponding tucking needle.
Therefore, the upper surfaces of the warp yarns adjacent the outer edge of the cloth and immediately ad jacent the fellof the cloth are engaged by the relatively narrow or thin lower edge of a vertically adjustable warp-engaging plate 72 whose upper portion is provided with a pair of vertically extending adjustment slots 73 loosely penetrated by respective screws 74 for securing the plate 72 in the desired vertically adjusted position to the rear surface of support bracket 50. Thus, upon temple 40 being adjustably positioned at a relatively higher than normal level such that, in the absence of the warp-engaging plate 72, the warps at the fell would be disposed inthe given path of travel of the tucking needle, the .plate 72 is adjusted downwardly relative to bracket 50 so as to engage and guide the warps downwardly adjacent and relative to the temple so that, in other words, the warps will pass beneath the lower edge of warp-engaging plate 72 and then pass upwardly into engagement with lower edge of the rear flange of channel member 41 and then over the burr roll 42, thus maintaining the forward portions of the warps adjacent the corresponding side edge of the cloth 15 in proper alignment with the path of tucking needle 70. A detailed illustration and description of tucking needle 70 is deemed unnecessary since they are well known. For example, such a tucking needle is shown in U. S. Pat. No. 2,034,487, issued to Rudolph Rossmann on Mar. 17,1936.
In operation, it may be assumed that a terry cycle of the loom has just been completed in the formation of a transverse row of terry loops in the cloth 15. Follower 25 (FIG. 1) then will be in engagement with the high surface of terry cam 26, and the fell of the cloth 15 and the temple 40 will occupy substantially the normal, rearward, or fast pick position as shown in FIG. 4. With the fell and the temple 40 occupyingthe latter position, the fell is positioned about 6 inch rearwardly of plate 72 and about 3/ 16 to V4 inch rearwardly of the rear flange of channel member 41. Channel member 41 then may be in engagement with warp engaging plate 72 or it may be spaced slightly forwardly from the plate 72. In the absence of plate 72, which need not be used in the event that the loom is not equipped with a tucking needle 70, the channel member 41 then may be positioned closer to the fell, since it is only necessary that the reed. 11 does not strike any obstruction, such as the warp-engaging plate 72 or the channel member 41 during the beat-up strokes of reed 1 1.
Upon starting a succeeding terry cycle of the loom, as the first loose pick of weft is being inserted in the warp shed, the low surface of terry cam 26 moves into engagement with follower 25 so that the cloth and the ground and terry warps are advanced forwardly, abnormally, to position the fell in the range of about 3/16 to $6 inch forwardly of the beat-up point of reed 11, de-
pending upon the desired length of loops to be formed.
In so doing, the cloth 15 transmits forward motion therefrom directly to temple 40, thus moving the same forwardly with the cloth.
The rear adjustment screw 65 is so positioned that, upon termination of the desired amount of forward movement of the cloth 15, adjustment screw 65 will move into engagement'with stationary abutment 63 as shown in FIG. 3, whereupon the cloth may advance the equivalent of about one pick of the loom relative to temple 40 as normal take-up is imparted to the cloth by take-up roll 16. Reed 11 beats up the first loose pick to the normal beat-up position which is then spaced rearwardly from the fellof the cloth, this occurring at about the same time that the forward movement of the cloth is terminated. Thereupon, at least one additional loose pick of weft is inserted in the shed and beat up by reed 1 1 whereupon a fast pick of weft is inserted in the warp shed.
However, as the fast pick of weft is being inserted, the high surface of terry cam 26 moves into engagement with follower 25 to again shift the cloth l5 and the ground warps 12 rearwardly relative to terry warps l3 and to position the fell at the normal beat-up position. At the same time, the rearward movement of the cloth in engagement with temple 40 imparts rearward movement to temple 40 until the rear flange of channel member 41 engages or moves into close proximity to the front surface of warp engaging plate 72, at which instance the front set screw 64 moves into. engagement with stationary abutment 63, as shown in FIG. 4. Reed 11 then beats up the fast pick of weft, along with the two or more previously formed loose picks of weft, agaihst the fell of the cloth to form another transverse row of terry loops from the then slackened length of terry warps. During the beating up of the latter fast pick of weft against the fell of the cloth, the take-up roll 16 is advancedin the usual manner to take-up the cloth the equivalent of one pick. Thus, the temple 40 is moved forwardly only one pick during the corresponding fast pick of the loom.
From the foregoing description, it is apparent that the latter one pick length of the cloth is taken up relative to the temple 40 when the temple subsequently reaches its forwardmost position in the course of an immediately succeeding terry cycle of the loom. It is important to note that, during each terry cycle, although the cloth is advanced three or more picks forwardly relative to temple 40, the cloth never moves in a reverse direction, at least to any noticeable extent, relative to the temple and, thus, the burr roll and the burrs 43 thereon will not mutilate or otherwise damage the edge portions of the cloth or the loops thereof.
In the transition from terry weaving to non-terry weaving of the loom, since the last pick of the loom in forming the terry area of the cloth is a fast pick, it is apparent that the parts will occupy substantially the position shown in FIG. 4 as the first pick of weft is beat up in the weaving of a non-terry area. During subsequent picks of the loom in weaving the non-terry area, and assuming that the non-terry area is to be of greater warpwise length than that of the shifting movement of the cloth incident to terry weaving, the temple 40 will move forwardly with the cloth during normal take-up of the cloth until the rear set screw 65 engages abutment 63, whereupon the cloth will simply be advanced one pick in length relative to temple 40 during each beat-up of the reed. Thus, as the last pick of weft is beat-up by reed 11 in the forming of a non-terry area, temple 40 may occupy the forward position shown at FIG. 3, but the fell of the cloth then will occupy the normal fast-pick position in which it is shown in FIG. 4.
Upon again starting the weaving of a terry area, the cloth 15 and warps 12, 13 will again be advanced forwardly to the abnormal position as the first loose pick of weft in the corresponding terry cycle is inserted in the warp shed. Obviously, since the temple 40 already occupies a forward position at this instant, it follows that the cloth is advanced in a single movement the full 3/16 to A inch relative to the temple 40. However, it is unlikely that the corresponding length of the cloth 15 then would have any loops thereon. Also, even if there were any loops on the portion of the cloth then being advanced through the temple 40, it is to be noted that the cloth is still being moved in only one direction relative to the temple 40 and it is not at all necessary for the cloth to subsequently move in a reverse direction or to again move in a forward direction relative to the temple 40 in completing the corresponding and subsequent terry cycles of the loom. Thus the cloth and terry loops thereon are not damaged by movement of the cloth through the temple 40.
In the drawings 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 and not for purposes of limitation.
