  • Patent number: 6296159
    Abstract: A device has been realized for turning tubular textile products inside out, in which a tubular body (22), designed for the purpose, is moved between an idle position and a working position for executing this operation. Active means of suction on the tubular body (22) create a flow of air inside said body when it is in its operative position, and pick-up means (21), placed at the operative position of the tubular body (22), hold the textile product (3) and fit it externally onto the tubular body. Once the product (3) has been fitted onto the tubular body (22), this latter moves from the working position towards the idle position gradually drawing on the textile product and thus completely automating the reversing process.

When the half made pantyhose are on their way to the toe part sewing machine with the panty part held by clipping members and the leg parts dangling from a guide pipe of the panty part sewing machine, the belt conveyor, disposed between both the paths of clipping members of the panty part sewing machine and suction members of the toe part sewing machine, correctly receives the leg parts one by one in association with a guide member disposed in contact with the belt conveyor at a little time interval. One of the leg parts, received by the belt conveyor first, is delivered, by their suction, to the suction members then coming nearby; the other is delivered in the same way a little later.

  • Patent number: 4620650
    Abstract: A carriage is reciprocately movable along the length of a pair of eversion tubes which carry pantyhose legs in an everted condition. The carriage carries two pairs of grippers which are engageable over each pantyhose leg and on side fingers on each tube. The grippers are brought to a partially closed position where they do not touch the fabric while the carriage is slowly moved along the tubes to scan the exterior of the fabric. A detection point is provided on the fabric which is detectable by a probe that operates a mechanism for fully closing the grippers. Further movement of the carriage with the grippers closed causes sliding of the fabric on the tubes. Even with the detection points misaligned on the tubes, the grippers will close at the appropriate instant to concurrently bring both legs of the pantyhose to the ends of the tubes.

  • Patent number: 4047649
    Abstract: In a hosiery handling apparatus wherein a string of hosiery is placed on a movable hollow tubular form, and everted through the open end of the form, a reciprocating arm grasps the first in-line hose and breaks it away from the string. The arm then pulls the hose across the top of a horizontal platform to a predetermined, fixed location on the platform. During the pulling operation, frictional resistance (drag) between the hose and platform tends to straighten the hose. An upstanding guide member, formed on the platform, prevents the hose from moving laterally off the platform. After the hose is located on the platform, the platform is tilted downwardly to dump the hose into a neat stack in a tray located beneath the platform. This readies the hose for a subsequent seaming operation.

    Abstract: A machine is disclosed for turning inside out a tubular fabric (e.g. stockings), which comprises a fabric-container, a tube for turning the fabric inside out, said tube overhangingly extending from the container, an air-drawing and blowing unit for blowing air into and drawing air from said tube, air-stream deflecting means to cause the blown air-stream to be deflected towards the outside face of the tube and valve means. The mechanical structure is simplified over that of the devices of the prior art and the operation becomes continuous instead of being intermittent. Manual manipulations are virtually suppressed.

  • Patent number: 3949913
    Abstract: A hosiery inspecting, everting, separating and stacking apparatus including a U-shaped, elongated, tubular form axially pivoted adjacent one end for oscillatory movement in a vertical plane between a loading, intermediate inspecting and everting position and a separating and stacking position. Hosiery from a knitting machine is placed on the U-shaped tubular form in the loading position while still in a continuous string. Pulling the hosiery on the form over the open end and bunching the string on the form is facilitated by inducing egress of air during the loading operation. The form containing the hosiery string is moved during each cycle from the inspecting position where everting is performed by vacuum to a separating position where separation is preferably formed by a pulling-off operation with breaking of a knitted connector ring attaching the hose to the string.

  • Patent number: 3941285
    Abstract: The slitting and seaming together of hosiery blanks for producing panty hose is carried out by a single operator and during the usual everting, inspecting and toe seaming operation. The hosiery blanks are slit as they are drawn onto a tubular hosiery form and the upper end engages a heated wire slitter supported on one side of the tubular form and a predetermined distance from the open free end of the form. The heated wire slitter is supported between spaced guide plates which aid in directing the panty forming end portion of the hosiery blanks into engagement with the heated wire slitter.
