Abstract: The present invention relates to sharp three-dimensional embroidery that can express a three-dimensional design in detail with a sharp three-dimensional effect and save time for cleaning a sheet residue by completely covering a sheet, and a manufacturing method thereof. Three-dimensional embroidery according to an exemplary embodiment of the present invention includes: at least two sheets layered on the upper surface of a fabric panel; at least two layers of embroidery being layered on the at least two sheets; and a covering member covering the at least two sheets and the at least two layers of embroidery with a predetermined design.

Abstract: An embroidery sewing appliqué technique. A tacking stitch is produced and positioned inside a column of a fabric that holds down the fabric on top of a base or host material, such as a garment. Running parallel to the tacking stitch, a column or satin stitch runs near and to the outside of the tacking stitch. The column or satin stitch has a higher density than that utilized in normal embroidery applications. The higher density satin stitch varies with needle size and thread size. The satin stitch cuts the fabric along the outer edge of the fabric. The tack stitch on the inside of the satin stitch locks the fabric down therefore not allowing the inner edge of the satin to be lifted away from the garment by virtue of the running tack stitch and without a separate cutting step.

Abstract: In a sewing machine for covering chain stitch according to the present invention, a thread push member is mounted on a top cover shaft which drives a cover thread looper, and the thread push member is arranged on the cover thread guide. When swinging backward in association with a movement of the cover thread looper, the thread push member pushes the top cover thread passing through a guide hole of the cover thread guide, forcibly moves the top cover thread and keeps the top cover thread near a back end of the guide hole. The top cover thread is arranged at a predetermined position on a surface of a cloth without being affected by a force from the needle thread, and a covering chain stitch can stably be formed with the excellent appearance.

Abstract: Device for producing a fiber preform with virtually any desired surface geometry by a TFP process. A guiding device lays a fiber strand along virtually any desired path curve on a backing layer and a sewing head attaches the fiber strand on the backing layer by at least one fixing thread. The backing layer can be positioned in an xy direction in relation to the guiding device and the sewing head, wherein the sewing head and/or the guiding device can be positioned in a z direction. The separation of the positioning capabilities of the backing layer (xy direction) and the guiding device, the sewing head and the lower thread guide (z direction) provides a relatively simple device construction. Example devices can produce fiber preforms for dome-shaped composite components for use inter alia as pressure bulkheads for cabins in aircraft with virtually optimum properties.

Abstract: An upper decorative stitching device is designed to make it possible to precisely transmit the swing movement of a first lever which is capable of swing movements widthwise in a pendulum manner to horizontal reciprocating motion of a second lever, which is provided with a spreader. The device facilitates the operation of switching between an upper decorative stitching and no upper decorative stitching. A connecting rod (9) is provided at both ends with spherical bearings (10, 11) to provide a connection between the first lever (3) and the second lever (8), thereby converting the rotation of the upper shaft into the reciprocal movement of the spreader.

Abstract: The present invention provides a device for generating a loop or a file used in an embroidery frame and the device comprises a fore-back driving part including a fore-back driving motor, a first gear driven with said motor, a second gear driven by a means coupling with said first gear, a third gear driven by a co-axis of rotation with said second gear, a first stop bar to switch said motor positioned at the lower part of said co-axis and cam-shaped stoppers placed within the area covered by the rotation of said first stop bar; a left-right driving part including a left-right rotating motor, a fourth gear driven with said motor, and a shaft having a fifth gear associated with said forth gear at the one end and a worm gear at the other; and a lead arm part connect to said shaft and including a lead arm to generate a loop, a lead arm body to joint said lead arm, lever stoppers to suppress the rotation of the motor and a second stop bars placed with the area covered by the rotation of the lead arm wherein said ea

Abstract: A driving mechanism for a sewing machine includes a rotatable shaft coupled to one or more needles for moving the needles upward and downward in a reciprocating action. A rotary looper is rotatably secured to the sewing machine at a vertical axle and is coupled to the shaft for allowing the shaft to actuate the needles and the rotary looper simultaneously. A rod is vertically secured in the sewing machine and coupled to the rotary looper for rotating the rotary looper. Two bevel gears are secured to the rod and the shaft for allowing the shaft to rotate the vertical rod.

Abstract: A stitch and mechanism for forming such a stitch including three needles and cooperating loopers for forming three parallel rows of stitches that are joined by a spreader thread that lies on the upper surface of the work piece. The spreader thread is configuration to be on both sides of the three needles such that it connects and covers the three parallel rows of stitches.

Abstract: A device for embroidery machines for attaching ribbons, braid, or the like on a fabric background has an axially displaceable rod-like needle carrier with a needle for embroidery thread. A material pressure foot is swivelable around the axis of a needle bar. A shuttle for receiving a shuttle thread is arranged behind the fabric background. The needle bar is received by a hollow shaft which is rotatable relative thereto. A front face of the hollow shaft includes radially extending grooves which are arranged diametrically with respect to each other. Webs extending into the radially extending grooves are provided at the rear side of an annular disk-shaped retainer for the material pressure foot. The needle of the needle bar extends into the retainer and is connected to a lifting mechanism of the material pressure foot. At least a front segment of the hollow shaft is received by a sleeve which is rotatable with respect to the hollow shaft.

Abstract: This invention relates to a novel method and apparatus for making novel decorative fabrics wherein effect yarns are present on the fabric with the effect yarn being fed in a longitudinally compressed bulked condition imparting an expanded cross-sectional width to the effect yarn and wherein a stitching thread secures the effect yarn in the compressed bulked condition so that there is imparted to the fabric an appearance attendant to an effect yarn much larger than that actually present on the fabric.

Abstract: An embroidery sewing machine equipped with a needle bar driving mechanism and a thread take-up mechanism, further comprising a rotating mechanism for a cylinder and bobbin having a cylinder on which is mounted a rotary ring rotatable therewith around a needle and a bobbin which is mounted on the rotary ring rotatable therewith, a device for transmitting the rotation of the first shaft to the cylinder to be rotated accordingly, a cylinder lifting mechanism including a linking means which transmits the up and down lifting motion of an L-shaped arm to the cylinder which inturn is shifted correspondingly through the actuation of an eccentric cam means and a retainer member which is devised to retain the L-shaped arm at a predetermined position by the medium of a supporting arm with which the retainer member is engaged.

Abstract: A stitching head for a stitching or embroidering machine for forming stitches fixed to the machine by a support including at least one needle which is associated with a main presser foot having a pressing heel. The stitching head has an auxiliary presser foot which is independent of the main presser foot and has a heel pierced with an opening. The auxiliary presser foot is mounted for sliding, with respect to the support, along an axis parallel to the needle, whereby its heel is disposed in the path of the downward movement of the main presser foot parallel to and spaced apart from the pressing heel of the main presser foot, while having its opening situated in the path of the needle. A helical spring is mounted for permanently urging the auxiliary presser foot toward the main presser foot.
