  • Patent number: 4536891
    Abstract: A method of manufacturing pantyhose by means of sewing machine using hose shaped leg parts comprises arranging the leg parts in a flattened side by side longitudinal relationship, cutting each leg part along an edge from the waist rim of its panty area up to a crotch leaving a remaining leg portion of each leg uncut so as to form upper and lower plies of each leg cut along their inner opposite edges, sewing the cut edges of the laterally adjacent plies together from the waist rim to the crotch to form a seam, deflecting the outer plies outwardly to overlie the remaining leg portions and continuing to sew the seam by sewing in the same direction the edge portions of the upper plies together. A sewing machine carrying out the invention includes a presser foot having a sole with a toe shaped front part which engages into each leg portion of the pantyhose to be formed.

  • Patent number: 4144825
    Abstract: A device for the removal of flexible workpieces which are draped over a workpiece holding arm and which hang downwardly from each side thereof, in particular, over a work-handling arm of an arm-down sewing machine, comprises a horizontally disposed carrying arm or rod which is adapted to receive the sewn material and support it so that portions hang downwardly from each side thereof. A material engagement clip, which has a pair of clamping arms arranged below the carrying arm, is mounted for movement in directions substantially parallel to the carrying arm in order to move the clamping arms on respective sides of the workpiece and subsequently to move the clamping arms together so that they clamp the workpiece and strip the workpiece from the carrying arm when the clamping arms are moved outwardly from the carrying arm.
