(Cl. `11W-+308) lThis invention relatesfto a novel'methodof, and `an apparatusfor, winding` up asubstantia-lly endless Vweb `of Ktextile Lmaterial such Yas cloth woven on -a loom or knitted-material produced ina-Warp oro-tricot knitting-machine.

`It has been a long standing practice in 'the :weaving industry to have a large number of automatic looms 'tended'by a single weaver Vwhois charged withthe performance of various'duties incidental to the Weaving Iof rst quality cloth. These dutiesV include the --stopping-of looms that are -mec'hanically out 'of crderor Weaving'substandard cloth andflagging or` otherwise notifying fthe `loom'iixer =assigned to "his vlooms whose duties'include maintaining andkeeping looms in suchrepair that standard, nrst 'class clot-h can beiwoven. fIn thefconventional loom, thevisible pathof the 'cloth "from the 'fellfto the receiving roll is relativelyrshort so Ithat -theca-pacity ofea Weaver,"`loomxer, supervisor or others'to note errorsA in the'-weaving=ofa large-number of looms and to takelappropriate vcorrective action is quite limited. 'i This limitation on -the capacity of the weave room personnel to inspect'the goods woven by: a `battery of' looms I-hasexisted'for -many years, butto date no adequate f'soluti'onffor enhancing the `capacityfor inspecting the'goods has been perfected, As a result, additional time, space, equipment and personnelmust be made available since: each: rolloff-'c'loth wound `'on areceiving `roll in the conventional Ymanner must be rewound Aor otherwise handledso that it 'can-begiven-careinspection'lbefore iinishing=or shipping. "Such inspection must f of inecessity `4be v`v'made -at lsome other fplace on :another machine, 'and after "a lapse of considerable time -a'fterlweaving `when :quality control of the cloth lcannot beasquickly or. effectively applied. L A

The receivingroll on Whichlthe woven "goods are Woundfonthe conventional loomis vmounted '1 Within thefframe of the-loom beneath, and sometimes'in frictional ycontact with, 'theltensioning vor sand roll, which ydraws/the goods v'out-oi "the loom against the action of .the brake band on the warpbeam. 'The complicated mechanism -of 'l ka conventionalloomthat must or -necessitybe contained within Y' its "framework and v the permis- 'sible'height v'of the loom above-the iloor, "from an operationalpoint 'of vievv,4 limits considerably the space thatiis available rto the 'reeciving roll. -As

a zresult, @receiving 1 rolls 'that are :obtained l'from conventional looms v.are limited in size so Vthat `usualiy'no morethan about V200 yards vl-of `goods icani'be wound on a roll. `itlthis pointlthe -roll must -be doied vfrom fthe 'loom fand a `:new lroll mustbe'started.

:It yis :1an `object of *the present invention lto .provide 4apparatus for @and a f method I Aof Winding :up the goods ywoven by 1a fconventional" loom in -suchfia mannerthat afrelativlylargeeareaI ofthe goodsris'visible at alltimes to inspectors, supervisors,weavers and vloom'iixers so that their ca pacity for detecting ilaws in the goods isenvhancedtosuch-a considerable degree that there- Wind inspectioncan'be avoided entirely and correction canbemade before an appreciable quantity of substandard cloth is woven so asto insurequality production. By-achieving this object, the causes of lsubstandarci weaving can be "determined immediately and the `responsibility therefor can be fdenitely placed, 'thereby enabling a mill'to better evaluate the-operatives involved and to supervise, instruct, andA train them.

Another-objectfof the present 'invention isto provide appa-ratus'for` and a method of winding up the fgoods on Aa receiving 4roll Vthat can take a `considerably greater yardage of goods before it must bedoffed and anotherrollstarted.

It has now vbeen found that these and other objects land advantages can be attained in a novel Way by modifying the structure oiy anyconventionalloom in suchl a manner'as to wind up the goods on a receiving roll rotated at a peripheral-speed substantially equalto the linear speed kat which they are produced andpositioned at acdistanceffrom the loom that is-suicient to give the 'vweaver, loomxer, inspectors supervisors and others ample opportunity to discover defects in theweaving and to take appropriate corrective action. In general, the inventioncontemplates the yremoval of the conventional receiving -roll rfrom within the 'framework ofthe loom and the winding npof the goodson a receiving roll at 'a'convenient location under the floor of the weave room, By'fthis means, the conventional placing of "batteriesof looms along weaver lane within reasy reach 'oi' the Weaver and other personnel is not disturbed-and a relativelygreat length of goods-is visible as the goods come oil. the loom. Furhermore, it vprovides van arrangement that minimizes interference between the operation of the loom andthe cloning Yof wound rolls of `goods because these'operations are carriedout 'on 'diffferent levels. Q

lAlthough in the following detailed description andinthe accompanying drawing theinvention is 'described `and killustrated lparticularly as appliedtothe winding up of greige goods as they come from the loom, itI islto be clearly understood that the invention -is notlimited to such application-but maybeapplied equally well to other machinery rsuch as lis used for Warp or vtricot knitting.

The foregoing and other `objectsythe utility and advantages -of the "invention-Y Will become apparent -'fromthe-following 'description and from the accompanying drawings -wherein:

Fi-gured is a iront elevationot conventional `loommodified lin-accord-ance withfthe principles "off this invention The loom shown in Figure 1, mounted upon4 iioor |0 of the Weave room, is a conventional loom such as a Northrop loom having side frame members |I, an arch |2, harnesses I4 and*` I6 of the usual strap and roller connection comprising straps l1 and I 9 and rollers 29. The loom is equipped with the conventional warp beam 2|, from which the yarn 22 passes over the whip roll 24 through lease rods 2S, harnesses |4 and I6, and the usual lay and reed, vand over and around a tensioning roll 21, sometimes also referred to in the art as a sand, friction, or draw roll. The tensioning roll 21 is driven by a train 29 of gears shown schematically in Figure 2 and which are moved by a drive shaft 30 or any other suitable source of power. These parts of the loom are well known and form no part of the present invention. The innumerable details of a conventional loom have been omitted from the drawing `because they :are unnecessary to a proper understanding of the present invention and would in fact detract from the prominence given to the illustration of the inventive features. y

One modification of the present invention, as specifically illustrated in Figures 1 and 2, com.- prises supporting a ilo-ating receiving roll 3|, loelow floor I0 of the weave room and upon a windup roll 33, within a pair of V-frames 32 bolted or otherwise affixed to the underside of floor |0. Receiving roll 3l is wound onto cloth shell 34 which may, if desired, consist simply of a hollow paper or cardboard tube. A shaft 36 is provided to support cloth shell 34. shaft 36 protruding from cloth shell 34 is adapted to rest freely against one of the dependent members of each V-frame 32. Each pair of V-frames 32 is maintained in suitable spaced relation by means of a spacer bar 31 and provided with a set of bearing blocks 39 designed rotatably to support shaft 40 of wind-up roll 33. wind-up roll 33 and the same end of tensioning roll 21 are provided with sprockets 4| and 42 of equal size and said sprockets 4| and |22 are connected by an endless sprocket chain 44 that passes through noie 45 in noe-r m. The diameter of windup roll 33 is preferably made the same as that of tensioning roll 21 so that the peripheral speeds of tensioning roll 21 and wind-up roll 33 will be approximately equal. Shims 4S or other appropriate means of .adjustment may, if desired, be

provided between bearing blocks 39 and the horizontal members of V-rame 32 so as to facilitate adjustment of the tension in chain d4.

In operation, wind-up roll 33 is driven by means of chain 44 and 'sprockets 4| and 42 at sub-1 stantially the sameV or slightly .higher peripheral speed and in the same direction as tensioning roll 21. The greige goods pass over tensioning roll 21 downwardly through cloth guard 49, through a slit 53 in iloor |,*around wind-up roll 33, and between receiving rroll3| and wind-up roll 330, to be wound up on the former. A polished insert 53 suitably curved to avoid a sharp bend Vin web 41 may, if desired, be fitted `into slit 50 as shown to minimize abrasive action on web 41. Wind-up roll 33 drives receiving roll 3| by frictional contact. As the diameter of receiving roll 3| increases, shaft 3S which rests freely against one side of V-frame 32, rides up along said side of said V-frame. When a pre- Each end of- One end of adjacent' the slit in the oor to v determined yardage of goods has been wound on receiving roll 3|, said roll and, if desired, the

cloth shell, may be doied by any suitable means. It has been found that up to about 2,000 yards of goods can be wound up on a single receiving roll 3| before it need be removed from V-frames 32 by a hand truck or the like, that rolls of such size can easily be subjected to further :tinishing operations, and that garment workers nd it advantageous t0 use such large rolls.

It is -apparent from the foregoing description that the woven goods are visible to the operator of the looms from the fell, i, e., the point at which the lay beats up the filling at each pick of the loom, unti1 they enter cloth guard 49. While the speed of the loom depends upon its model or construction, the width of the goods and upon the material that is woven, it has lbeen found that in weaving a 42 inch wide web of cotton on an X model Draperloom, the goods travel through this distance in about ten minutes, thus giving ample time to check on the operation of a large number of looms inasmuch as inspection of the area described can be carried out almost at a glance. Furthermore, personnel stationed on the oor below'have exposed to their view an area of goods equal to or greater than that seen above the floor. o By lengthening the V-frames and by other'arrangements, greater inspection surfaces can be provided below the floor. The V-frames 32 can conveniently `be given the same number as the loom `on the door above and the downstairs personnel can quickly inform the operators upstairs if the goods from any particular loom are woven defectively. This provides a double check of the quality of goods produced and is an important added advantage of the invention. A source of light may also be placed behind the woven goods at any point along the path to assist in the visual inspection and, if desired, light sensitive means may be employed in cooperation'therewith to automatically mark thin places inthe goods, to stop the loom, or to otherwise call the attention of the operator to such defects inthe weave.

It is to be understood, of course, that the term receiving roll, as used herein, is intended to` include any roll upon which the material maybe wound either temporarily or for shipping purposes. It is sometimes also referred to in the art as a package roll or cloth roll. Y

The term tensioning roll, as used herein, is a generic term to designate anyV type of'roll that is used to pull the woven or knitted goods through the machine and is variously referred to in the art as a sand roll, friction roll, draw roll, etc. f

It is obvious that upon reading the foregoing description of the invention, many changes, alternatives and modiications'will occur to those skilled in the art of weaving. Thus, for example. the travelv of the goods immediately afterthe lling is beaten up may be considerably diiferent, depending upon the particular type of loom that is used. The goods may travel over'a breast beam, and idler roller, then aroundY a tensioning roll and perhaps around another idler roller before it is passed Vthrough the floor to be wound up on the receiving roll. Idler rolls may also be positioned minimize rubbing of the goods against the ooring. Instead' of passing the goods around the wind-up roller before they are wound up on the cloth shell, they may be wound directly upon the receiving roll, as illustrated schematically in Figure 3. In that event the drive for the wind-up roll shouldcbe re,-

versed so as to rotate it in the direction opposite to that of the tensioning roll. This may be accomplished simply by crossing chain 44 or by using the sprocket of a reversely rotating shaft to drive the chain. The diameter of the tensioning roll and the wind-up roll need not be substantially equal so long as the drive is such as to provide for rotation at approximately equal peripheral speeds.

It is also quite possible to vary the drive for the wind-up roll in many different ways. It may be driven by means of a shaft and bevel gear arrangement, by a worm gear and shaft drive, or by a V-belt and sheave drive. The chain or equivalent drive, instead of being taken from the tensioning roll, may be taken from any other rotating shaft, such as from a gear or sprocket driven by the pick gear train, or by a ratchet wheel with an actuating pawl driven by cam action from an eccentric on the main shaft of the loom. It is also quite possible to provide an individual drive for the wind-up roll, such as by means of a constant torque motor driving the shaft through a worm gear or the like or to eliminate the wind-up roll entirely and drive the receiving roll directly through a suitable clutch, constant torque motor or the like that will operate to rotate the receiving roll with a peripheral speed approximately equal to the peripheral speed of the tensioning roll.

The V-frame arrangement on which the receiving roll is supported may also be varied considerably. Thus, for example, a trapezoidal frame may be supported on the floor below the weave loom floor to support two or more receiving rolls from opposite or adjacent looms on the floor above. The shaft of the cloth shell need not necessarily float or ride freely along an inclined member of the supporting frame but may be guided vertically between channel members. When the shaft of the cloth shell is so mounted, it may be desirable to pass the cloth over one or more idler or guiding rolls before it is wound up on the receiving roll. It is also within the con` templation of this invention to provide the shaft for the cloth shell with gears that will mesh with gears on the shaft of the Wind-up roll so that proper winding up of the first layers of goods on the receiving roll will be assured even though the weight of the receiving roll may not at the time be sufficient of itself to insure a tight winding of the goods thereon. It is also quite possible to provide a tensioning device between the cloth roll and the lower portion of the support frame or the wind-up roll to insure proper winding up of the goods, especially in the initial stages.

All such modifications, alterations and variations of the invention are intended to be included as come within the scope of the appended claims.
