Definitions

  • first passageway in a direction from the end adjacent the redirecting member to the other end of the first duct for drawing tubular knit fabric therethrough.
  • the air blower also moves air through the second passageway in a direction from the other end of the first duct toward the end adjacent to which the member is mounted.
  • the air moving in the second passageway is redirected by the member so as to move in a substantially longitudinal direction from the one end to the other end of the second duct along the exterior of the second duct. This air flow moves tubular fabric over the exterior of the second duct to collect tubular fabric around the second duct as it is withdrawn from a supply roll of the fabric.
  • one end of the length of tubular fabric is placed by an operator over the end of the second duct and air flow from the blower is directed through the second passageway and redirected by the member for moving the tubular fabric along the exterior of the second duct toward the other end thereof.
  • This movement is continued until the source of supply is exhausted and the entire supply of tubular fabric is collected on the exterior of the second duct at which time the air flow through the second passageway is terminated by the operator.
  • the operator then inserts the end of the supply of tubular fabric on the second duct into the first passageway.
  • Air flow from the blower is then directed to the eductor for moving the air and the supply of tubular fabric through the first passageway from one end of the first duct toward the other end and through the eductor.
  • the effect of this operation of the everting apparatus is to turn the inside of the fabric outside. Therefore, the fabric discharged from the eductor is ready for subsequent processing of the fabric with the inside of the fabric exposed.
  • the outer manifold contains a plurality of apertures which form air jets directing air flow outwardly and downwardly from and at an angle with the longitudinal axis of the member.
  • the inner manifold also contains a plurality of apertures which form air jets directing air flow inwardly and downwardly from and at angles with the longitudinal axis of the member.
  • the everting apparatus of this invention includes a first elongated tubular duct which defines a first passageway therein and a second elongated tubular duct disposed concentrically about the first tubular duct to define a second fluid passageway therebetween.
  • the ducts are preferably disposed substantially horizontal.
  • An annular air flow redirecting member is mounted adjacent one end of each of the ducts.
  • An air blower. by means of an eductor mounted on one end of the first duct, moves air and tubular fabric through the first passageway in a direction from the one end of the first duct toward the other end thereof and through the eductor where it is discharged ready for subsequent processing of fabric moved therethrough.
  • the blower also moves air in the second passageway in a direction from the other end of the first duct toward the one end thereof.
  • the air moving in the second passageway is redirected by the member so as to move the air and tubular fabric in a substantially longitudinal direction from the one end of the second duct toward the other end thereof along the exterior periphery of the second duct for collecting the tubular fabric thereon as it is withdrawn from a supply roll of the fabric.
  • the air flow from the blower is directed by a diverter valve to either the eductor or the second passageway as desired.
  • one end of a supply of tubular fabric is placed by an operator over the end of the second duct and the diverter valve is positioned to direct the air flow from the blower into the second passageway where it is redirected by the member to move the air and tubular fabric along the exterior of the second duct in a direction from the one end of the second duct toward the other end thereof.
  • the air flow is shut off to the second passageway and the operator places the other end of the supply of fabric into the end of the first passageway.
  • the diverter valve is then shifted to direct the air flow from the blower into the eductor for moving the air and the tubular fabric through the first passageway in a direction from the one end thereof to the other end and through the eductor.
  • the effect of this operation is to turn the fabric in side out. Therefore, the fabric discharged from the eductor is ready for subsequent processing of the fabric with the inside of the fabric exposed.
  • the invention provides an extremely structurally simple apparatus which contains only two moving parts, i.e., the blower and the diverter valve for directing the air flow from the blower selectively to either the eductor or the second passageway. Also because the apparatus is advantageously positioned horizontally, the operator thereof does not have to climb up and down a ladder to feed the cloth over or into the apparatus. Furthermore no additional moving parts, such as the rollers of the prior art device, are needed to evert the cloth, i.e., the force of the moving air is sufficient to effect the everting operation. While rollers such as those in the prior art device could be used in conjunction with this invention, they are not necessary for its complete efficient operation.
  • Another object of the invention is to provide an everting apparatus for tubular fabric which contains as few moving parts as possible.
  • a further object of the invention is to provide an everting apparatus for tubular fabric which requires a minimum amount of work on the part of an operator thereof. In accordance with this object, it is not necessary for an operator of the everting apparatus of the invention to climb up and down on a ladder or to use other elevating apparatus to feed cloth over or into the apparatus.
  • FIG. I is a perspective schematic view of the everting apparatus of the invention illustrating the collection of tubular fabric about the exterior of the second duct as it is fed from a supply roll of the fabric.
  • FIG. 2 is a side view, partly in section. showing the structural details of the everting apparatus.
  • An everting apparatus generally indicated as 10 is provided by connecting a first elongated tubular duct 12 in a horizontal position on a frame 20.
  • the first duct 12 defines a first passageway 13 therewithin.
  • the duct 12 is connected, by bolting or welding, etc., to an upright 21 on the frame 20.
  • a second tubular duct I5 is disposed concentrically about the duct 12 and defines a second passageway 16 with the duct 12.
  • the first and second ducts are preferably disposed in a substantially horizontal position.
  • Adjacent one end 12a of the duct 12, a substantially annular air flow redirecting member 18 is mounted.
  • the member 18 includes a first portion 180 which is connected to the end 120 of the first duct 12.
  • the first portion 180 extends radially outwardly from its connection to the duct 12 to a region radially outward of the duct 15.
  • the second portion 18b is substantially annular and extends from a radially outer region of the portion 18a in a direction from the portion 180 toward the frame 20.
  • the duct 15 terminates a short distance from the end 12a of the duct 12 to provide a circumferentially extending opening 9 which opens from the second passageway 16.
  • the opening 9 opens from the passageway 16 into a third passageway 8 formed between one part of the portion 18b of the member 18 and the end 150 of the second duct 15.
  • a plurality of angularly spaced radially extending bars 1 1 interconnect the portion 18b of the member 18 and the end 150 of the second duct 15.
  • a rotary blower 30 is provided within the frame 20.
  • a third duct 31 having portions 31a, 3lb, and 31c guides the air blown by the blower 30 to the passageway 16 and to an eductor 35 to be subsequently described.
  • a diverter valve 37 is provided in the duct 31.
  • the diverter valve 37 is slidably movable in the portion 31b of the duct 31.
  • the diverter valve 37 is mounted on the end of a piston rod 38 of a piston which rides in an air cylinder 39 one end of which is mounted to the frame 20.
  • the piston rod 38 extends through an aperture cut in one end of the duct 31b.
  • Appropriate valving not shown controls the movement of the piston in the cylinder 39 and through the piston rod 38 controls the movement of the diverter valve between its forwardmost position shown in solid lines in FIG. 2 and its retracted position shown in dotted lines in that Figure.
  • the diverter valve 37 includes an arcuate face 370 which. when the diverter valve 37 is in its retracted position. directs the air blown by the air blower 30 through the portions 31b and 31a of the duct 31 into the second passageway 16. When the diverter valve 37 is in the retracted position it blocks the flow of air in duct portion 31c from the blower 30 to the eductor 35. When the appropriate valving is shifted to move the diverter valve 37 to its forwardmost solid line position shown in FIG. 2, the diverter valve 37 no longer blocks the duct portion 31c so that the air blown by the blower 30 is permitted to move through duct portion 31c into the eductor 35.
  • the eductor 35 is connected to the end 12b of the first duct 12.
  • This eductor may be of the type disclosed in US. Pat. No. 3.276.821 whose disclosure is incorporated by reference herein.
  • air moves through the first passageway 13 in a direction from the end 12a of the duct 12 to the other end 12b thereof.
  • a supply reel 23 having a length of tubular fabric wound thereon.
  • an operator positions the free end of the tubular fabric over the end 100 of the everting apparatus 10 and switches the valve mechanism to move the diverter valve 37 into its retracted position.
  • the operator then actuates blower 30.
  • the air blown by the blower 30 is directed by the diverter valve 37 through the portion 310 of duct 31 and into the second passageway 16 in a direction from the end 1212 of the duct 12 to the end 12a thereof.
  • the air moving through the passageway 16 is redirected by the member 18 so as to flow through the opening 9 into the passageway 8 and along the exterior of the second duct 15 in a substantially longitudinal direction from the end 15a of the duct 15 to the end 15b thereof.
  • the force of this air moves the tubular fabric longitudinally along the exterior of the second duct 15 as shown in FIG. 1. This operation continues until all of the tubular fabric wound on the reel 23 is collected on the exterior ofa second duct 15.
  • the valve mechanism is then actuated to shift the diverter valve 37 to its forwardmost position so that the air blown by the blower 30 is directed through the portion 31c of the duct 31 into the eductor 35 to thereby cause air to move in the first passageway 13 in a direction from the end 12a of the duct 12 toward the other end 12b thereof.
  • the operator may deactuate the blower 30 or keep it actuated.
  • the operator then takes the end of the tubular fabric on the second duct 15 adjacent the end 10a of the everting apparatus 10 and places that end into the first passageway 13. If the blower 30 is deactuated, the operator again actuates it.
  • the tubular fabric is forced by the air moving in the first passageway 13 to move through the passageway 13 in a direction from the end 12a of the duct 12 to the other end 12b thereof and through the eductor 35 where it is discharged through the end 36 thereof.
  • This operation continues until all of the tubular fabric previously collected on the exterior of the duct 15 is pulled through the passageway 13, the everter 35, and out of the end 36 thereof.
  • the effect of this operation is to turn the tubular fabric inside out. Therefore, the fabric discharged from the end 36 of the eductor 35 is ready for subsequent processing of the fabric with the inside of the fabric exposed.
  • the ducts 12 and 15 are preferably disposed as shown in a substantially horizontal disposition so that the operator does not have to use a ladder or elevating apparatus for positioning the tubular fabric on the everting apparatus. It is readily apparent that the everting apparatus of the invention could be disposed in other positions, including a vertical disposition as well as any of the various angular positions between horizontal and vertical. In fact, a substantially horizontal position in which the ends 120. 15a of the ducts 12, 15 are elevated slightly above the ends 12b, 15b thereof is desirable.
  • An everting apparatus for tubular fabric comprising a first elongated duct defining a first fluid passageway therewithin,
  • a second elongated duct disposed about said first duct and defining a second fluid passageway therebetween
  • a first pneumatic means for moving air through said first passageway in a direction from said one end of said first duct toward the other end thereof
