This invention relates to apparatus and method for turning a tubular fabric inside out and particularly to improved apparatus for handling cloth during such an everting operation.
Manufacturers of knit garments follow the practice of knitting the original fabric in the form of a tube of considerable length. After being knit the tube is rolled flat and at various times is unrolled and rerolled as it is carried through various processes prior to being cut into garments. At various stages its becomes necessary to turn the fabric.
In the present invention it has been found that an extremely rapid everting or turning operation can be accomplished with essentially simple feed roll apparatus based on employment of a turning tube open at both ends and preferably positioned at a vertical angle between true horizontal and true vertical. The present invention also approaches the everting problem from the viewpoint of providing an everting unit which can be moved to various locations within the plant thus eliminating the need for duplication of apparatus at each turning location.
An object of the present invention is therefore to provide an apparatus capable of everting tubular knit fabric at maximum speed with a minimum disturbance to the stitch alignment.
Another object of the invention is to provide a tubular fabric everting apparatus which can be easily moved as an integral unit in the plant to various processing points.
Another object of the invention is to provide a tubular fabric everting apparatus capable of handling and everting an extremely long fabric tube.
Another object of the invention is to provide a tubular fabric everting apparatus specifically adapted to utilize a turning tube tilted at an angle between horizontal and vertical.
Another more specific object of the invention is to provide a tubular fabric everting apparatus in which the fabric tube after being packed on the outside of the tube can be rapidly drawn through the turning tube at the start of the everting operation.
Other objects and advantages of the present invention will become apparent to those skilled in the art, from the following description when read in conjunction with the accompanying drawings wherein:

Briefly described, the present invention relates to an apparatus for everting a tubular fabric comprising a support means, hollow means having open ends supported on an end thereof on the support means, means for supporting a fiat wound coil of the fabric on the support means, means for guiding a length of the fabric over the unsupported end and onto the hollow means and means mounted on the apparatus engageable in holding relation with the trailing end of the fabric disposed on the hollow means having been inserted through the unsupported end of the hollow means, operable for drawing the fabric through the interior of the hollow means toward the unsupported end thereof. The apparatus preferably also includes a removable guide means mounted on the unsupported end of the hollow means for opening and guiding the fabric onto the hollow means, a first friction means mounted on the apparatus engageable with the fabric guided onto the hollow means, operable for advancing the same toward the unsupported end thereof and a second friction means operable responsive to slack conditions of the portion of the fabric extending between the wound fabric coil and the hollow means for unreeling the fabric coil.
Referring to the drawings, there is illustrated an embodiment of the invention. The basic turning tube represented generally by the numeral 25 is formed of a group of substantially smaller diameter tubes 26 parallel and evenly spaced and fixedly secured to the outside of a series of longitudinally spaced circular bands 27. Such an arrangement allows the operator to effectively reach into tube 25 at almost any point along its length. Tubular member 25 has a hollow substantially unobstructed interior and is formed as a substantially long tube open at both ends. The tubular member 25 is supported at its lower end only at a vertical angle preferably of about thirty degrees and in one form has been made about twelve feet long and about ten inches inside diameter.
Support for tubular member 25 is provided by arranging for each of the component tubes 26 to terminate in and be secured to a fixed heavy circular band member 28. Band member 28 is in turn secured to a pair of angled brace members 29, a pair of angled brace members 30 and a vertical brace member 31. Any suitable joining means such as welding, bolting or the like may be employed to secure the structure together.
The lower end of tubular member 25 indicated at 35, FIGURE 3, remains open during all phases of the turning operation. The upper end indicated at 36, FIGURE 2, is left open during the actual turning operation but is closed by means of a removable tapered nose device 37,
FIGURES 1 and 5, during the first part of the operation when the leading end of the fabric is being opened and manually placed on the outside of the upper end of tube 25. Nose 37 in the form shown consists of an upper, horizontally placed, U-shaped rod 38, a lower horizontally placed U-shaped rod 39, a connecting vertically placed rod 40, a horizontal top guide rod 41 and a thin circular band 42 to which rods 38, 39, 41 are secured and which is adapted to fit snugly in the upper end 36 of tube as illustrated by FIGURE 1. Rods 38, 39, 41 41 may be brass wire or the like brazed together at the intersections. In operation, as later explained, nose 37 serves to open the fiat fabric tube and direct it over the outside of the upper end of tube 25.
The turning apparatus is mounted on a base frame which includes side members 50, 51, end members 52, 53 (FIGURE 3) and cross and angled bracing members such as those indicated at 54, (FIGURE 2), 55, and 56. A suitable number of wheels 57 when mounted below the frame makes the entire apparatus mobile and easily movable from place to place in the plant where needed.
The tubular fabric prior to being turned is conventionally folded flat and delivered to the turning apparatus as a cell where it is initially placed in a receptacle or tub device 60 secured to the base frame and positioned below the upper end of tube 25, the receptacle device being best illustrated in FIGURES l, 2, 6 and 7.
As later explained, the coil of fabric, depending on its diameter, will rest on various of the small rollers 61-65 which are rotatably mounted between the tub sides 66 and 67.
To accommodate variation in width of the fabric coil there is provided a pair of thin, semi-circular plate members 68, 69 which are adjustably mounted on a rod 70 fixedly secured between the tub sides 66, 67.
In addition to the fabric coil supporting rollers 6165 previously mentioned, the tub device 60 also includes a rotatably mounted idle roller and a roller 76 which is rotatably driven at one end by a suitable motor 77 and belt drive 78. The driven roller 76 is preferably somewhat loosely mounted on its driven end with a degree of slack motion such that roller 76 drives only when the fabric passes around roller 76 and pulls on roller 76 so as to tighten belt 78. The full purpose of this clutch type action at roller 76 will be better understood as the description proceeds.
In the turning process, the flattened fabric tube indicated in FIGURE 1 by the dashed line 81 is led from the fabric coil indicated at 81 and is first passed over a roller 82 which like rollers 6165 and 75 is mounted between the tub sides 66, 67. The fiat fabric tube is then passed under and around driven roller 76 and then under and around an additional roller 83 which is rotatably mounted between extensions of the tub sides 66, 67. From roller 83, the fabric tube still in the flat form 81) passes to a further rotatably mounted roller 84. As indicated in the drawings particularly in FIGURES 1 and 2, roller 84 is positioned in front of nose 37 above tub 60 substantially in alignment With the axis of tube 25 and is mounted on an upper cantilevered frame structure which includes bent vertical post members 91?, 91 secured to the previously described base frame, straight vertical post members 92, 93 also secured to the base frame and a pair of bent cantilevered arms 94, 95 secured to the tops of post members 90, 91, 92 and 93.
After being manually fed to the upper end of tube 25, the leading end of the flat fabric tube 80 is opened into tube form and is spread over the nose 37 and is then manually guided over tube 25 as an open tube represented by the broken line 100. This initial manual operation therefore includes entraining the flat fabric 80 over rollers 82, 76, 83 and 84, and the starting of the fabric in tube form over nose 37 and over the upper, unsupported end of tube 25. In order to turn the fabric according to the method of the invention it is necessary to first store the entire length of the fabric tube on the outside of the turning tube 25 and much time is saved in this phase of the turning operation by employment of the drive apparatus next to be explained.
Referring to FIGURES l, 2, 8, 9 and 10, the fabric in the tube form is drawn down manually over tube 25 until its leading end lies between the relatively wide driven roller 116 and the relatively narrow idle roller 111. Roller forms part of a vertically adjustable bearing frame assembly which can be tilted so as to move roller 11% selectively against tube 25 and in contact with the fabric as in FIGURE 1, or tilted in the opposite direction so as to bring roller 110 out of contact with the fabric as in FIGURE 8. The mentioned assembly includes a pair of side rails 112, 113 rigidly joined to a pair of end rails 114, 115. Side rails 112, 113 in turn mount a pair of bearings 116, 117 through which pass a shaft 118. The ends of shaft 118 terminate in suitable mountings 119, 1219 in which the ends are secured by set screws or the like, not shown.
Suspended beneath and between and rigidly secured to side rails 112, 113 is a further bar 121. Fixedly secured to bar 121 is a motor mounting plate 122 towhich is aifixed an electric drive motor 123. Motor 123 is connected through a suitable drive belt 124 to drive the previously mentioned roller 110. While not shown, it should be understood that power is supplied to the various motors mentioned in the description through electric supply lines and switches appropriate to apparatus of this kind.
Drive roller 110 is mounted on and fixedly secured to a shaft whose ends are rotatably mounted in suitable bearings as indicated at 131. Bearings 131 are in turn secured to U-shaped brackets such as shown at 132 which are mounted below side rails 112, 113 at opposite ends of end rail 114. Shaft 130 is driven by a suitable pulley 135 which in turn is driven by the previously mentioned belt 124 and the motor pulley 136.
The position of the vertically adjustable drive roller 1111 with respect to the relatively fixed positioned idle roller 111 is regulated by the latch mechanism illustrated in FIGURES 9, 10 and 11, in which represents a vertical bar fixed to and below rail 112 and which is braced to rail 112 by an angle bar 141. Vertical bar 140 mounts the latch mechanism proper which includes a rod member 142 having a pivotal mounting 143 at one end, the other end of rod member 142 being fixed to a latch 144 having a lip 144' which may engage the bottom edge 145 of a fixed vertical bar member 146. Bar member 146 is rigidly secured to vertical post 90 and has a fixed position. A bolt and spring arrangement which includes a bolt 150 screwed into latch 144 and slidably mounted in vertical bar 140 assists in keeping latch 144 in position. A compression spring 151 which surrounds the body of bolt 150 between latch 144 and vertical bar 140 tends to keep latch 144 and bar 146 together. A handle 155 is fixedly secured to latch 144 and affords a convenient means for adjusting the position of drive roller 110.
In operating the latch mechanism to disengage roller 110, handle 155 is pulled downwardly until lip 144 is: below edge 145, after which handle 155 is manipulated to bring lip 144' in engagement with edge 145, which position it will hold due to the compression effect of.
spring 151. To engage roller 110, handle 155 is manipulated to disengage lip 144' from edge 145 and lip 144' is allowed to rise upwardly above edge 145 as in FIG- URE 11. It should of course be understood that the location of shaft 118 and the weight of roller 110 and motor 123 are taken into account and arranged such that roller 110 inherently tends to move downward and be resiliently engaged with the fabric tube. Roller 110 can however be disengaged by pulling downwards on handle 155 and engaging lip 144 with edge 145 in the manner just described.
Drive roller 110 and its mating idle roller 111 should be located a substantial distance from the upper end of the turning tube 25 in order for drive roller 110 to be able to operate on the fabric at relatively high speed. For example, with a twelve-foot long, roughly ten-inch diameter turning tube handling from fourteen-inch to thirty-six inch tubular fabric, the axis of drive roller 110 was located about three and one-half feet from the upper end of the tube. Drive roller 110 was made as a ten and one-half inch rubber covered pulley and was driven at about 650 r.p.m. With drive roller 110 located as described, fabric was observed to flow rapidly and smoothly with substantially no lag of that portion of the fabric running on the bottom of tube 25. Simultaneous with operation of drive roller 110, drive roller 76 in the form of a three-inch wooden roller was driven at about 800 rpm. whenever the flat fabric 80 between drive roller 110 and drive roller 76 would tighten so as to tighten the slack mounting at roller 76 and thereby tighten belt 78. That is, by mounting drive roller 76 so that its driving action depends on the tautness of the fabric between drive roller 110 and drive roller 76, drive roller 76 exhibits a clutch type action and cannot overrun the factic coming from tub 60.
After the coil 81 is completely uncoi-led, the fabric will lie folded and stored on the outer portion of tube 25 as indicated at 150. To complete the turning operation, it is necessary to remove nose 37 and to next draw the fabric through the upper end of tube 25, through the interior of tube 25 and out the lower end of tube 25. It is also necessary at this point to lift roller 110 to a disengaged position as illustrated by FIGURE 8. To assist in starting the fabric, that is the trailing end of the coil, through the interior of tube 25, there is provided a belt 160 which resides in the bottom of tube 25 and is trained over a hand driven pulley 161 and a series of idle pulleys 162, 163, 164, 165 all of which are suitably mounted in the bottom of tube 25 and which as schematically represented in FIGURE 12, tube 25 being represented by the dashed line 25'.
As shown in FIGURE 12, both upper and lower runs of the belt are carried inside the tube between idle pulleys 164 and 162 whereas between idle pulleys 164 and 165, the upper belt run is carried inside the tube and the lower belt run is carried outside the tube. This arrangement allows the upper belt run to run the full length of the tube 25 and keeps both runs out of the way of cloth gathered on the outside of tube 25. Belt 160 is punched with holes along its length to receive one end of a bent wire double hook device 170 illustrated in FIGURE 13 the other end of which is snagged into the end of the fabric to be pulled through the turning tube.
As illustrated by FIGURE 14, the operator after snagging the hook device 170 into the trailing end of the fabric that came from coil 81 then engages the hook device 170 with the belt 160 by inserting the opposite end of the hook device 170 with one of the holes in belt 160. The hand driven pulley 161 is then manually turned by means of the handle 171 which causes belt 160 to rapidly pull the fabric through tube 25 until it reaches the lower opening 35 of the tube, at which point the hook device 170 is disengaged from both the belt 160 and the fabric. Suitable storage boxes for hooks 170 are located at each end of tube 25 and are provided by the open receptacles 172, 173.
In order to rapidly complete the turning operation, the fabric is now led under an idle roller 180 which is mounted on suitable brackets 181 and in bearings 182. From idle roller 180, the fabric is manually fed along the path indicated by broken lines 196 to a driven roller 185 and an idle roller 186 both of which are supported from the base frame and are positioned substantially above the lower end of tube 25. Roller 185 is connected through a belt 187 to be driven by an electric motor 188 mounted on frame member 189 which in turn is rigidly secured to a vertical post member 190. Idle roller 186 as shown in the drawings is continually pressed against driven roller by suitable compression spring devices indicated at 195. With motor 188 energized from a suitable source, not shown, and the fabric initially manually fed between rollers 185 and 186, the fabric will be rapidly withdrawn from its stored position on the outside of tube 25, through the tube interior, and will be ejected from the rollers 185, 186 at a level appropriate to following processes or to suitable storage bins or the like. A suitable electrically grounded bar represented at 200 is preferably placed very close to rollers 185, 186, particularly when composed of rubber, in order to eliminate static electricity.
