  • Patent number: 9430956
    Abstract: A seam allowance guide aide label, Sewing with Color Label, to be applied to the surface of a sewing machine plate, as a stick-on label. The label has imprinted vertical and horizontal lines with colors; the first vertical line is the guideline to align the label to the default needle position for applying the label to the sewing machine's plate. The use of colors is a system to represent a standard measurement, known and accepted in today's sewing industry. The color system defines and establishes immediate differences between measurements, to achieve accuracy in positioning the edge of a textile to be sewn in a specific seam line without trouble of not recognizing numerical representations or seam grading lines in the actual plate of a sewing machine, either in imperial or metric system.

  • Patent number: 6332414
    Abstract: A sewing machine accessory with an accessory head which can be quickly and easily attached and removed from a sewing machine. One version of the accessory head can be mounted to a sewing machine foot, while another version can be mounted on a sewing machine shank. Either version can use a protrusion in a mating slot to serve as the mounting connection, configured so that simply inserting the protrusion into the slot is sufficient for attachment, and simply removing the protrusion from the slot is sufficient for detachment. A particular embodiment of the accessory can enable straight seams or hems to be sewn parallel to a material edge without requiring a steady hand or great skill by the operator. An edge guide is provided with a predetermined offset from the sewing machine needle, thus permitting the operator to guide the material through the sewing mechanism in a very straight line, with the resulting seam being a consistently accurate distance from the edge of the material.

  • Patent number: 5911184
    Abstract: An improvement to a sewing machine which allows ribbons, trim, elastic bands and other linear-shaped materials to be accurately and automatically controlled and guided as they are fed into the sewing mechanism. For elastic, an adjustable control is provided that automatically prestretches the elastic as it feeds into the machine. This control allows the user to adjust the amount of tension in the elastic, and thus control the amount of stretch which is sewn into the finished product. These features are implemented in a hands-free manner, so the operator is not burdened with having to manually guide the materials while simultaneously tending to all the other manual duties that a sewing machine operator must typically contend with. The invention is implemented with one or more guides which can be mounted on the sewing machine foot. Custom feet are provided to allow the invention to be retrofitted onto existing sewing machines.

    Abstract: A solid, rectilinear sewing form of thin, rigid construction and a process for using the sewing form to hand make cloth trim tape, cloth pockets or folded cloth rope is provided. The width of the sewing form controls the width of the finished cloth trim tape, cloth pockets, or folded cloth rope. The form is laid on top of cloth material so that the edges of the cloth material extend beyond the longitudinal edges of the form. The cloth extensions are then folded back over the sewing form using the edges of the form as parallel folding guides, and the cloth is creased at the folds by pressing with a hot iron. Longitudinal grooves run the length of the sewing form and serve as cutting guides for trimming the folded and creased cloth. Folded cloth rope is produced by making a third longitudinal fold and crease in the cloth material using the form as a folding guide, and thereafter stitching together the two edges formed by the first two creases.

    Abstract: A fabric guide device for a linking machine having a rotatable circle of radially extending points. The device guides fabrics, which are to be joined by a chain stitch, onto the points so that the fabric edges are located at a predetermined height relative to the points. The device includes at least one pair of opposed guide surfaces for engaging slidingly opposite sides of a fabric adjacent an edge thereof. Adjustable reference surfaces locate selectively the height of the fabric edges relative to the points. The device is particularly useful in the joining together of patterned fabrics. It permits fabrics which are to be joined to be held in correct pattern position relative to each other, so that adjacent parts of the pattern are impaled upon the same points. When the seam is made, the pattern shows a correct join.

  • Patent number: 3994246
    Abstract: In an apparatus for sewing articles, such as sewing a slide fastener chain to an opening in an article, stitching of thread to an article is initiated by a manual control and is terminated by an automatic control in response to the sensing of a terminal point, such as the terminal point of an opening, on the article.Article guiding facilities urge folded edge portions of an article toward each other by spring biased members on folding plates.A scroll for receiving and guiding a folded edge portion of an article has an adjustable channel.A linear motion apparatus, such as a dual needle holding mechanism, employs a linear motor driving a camming member which engages a locking member on a movable member to move the movable member to a selected position and to operate the locking member.

  • Patent number: 3973507
    Abstract: A work guide apparatus for a sewing machine providing a plate moveable in guided engagement with guide means attached to a base surface of the sewing machine. The plate carries a work piece along a path of motion relative to the sewing machine needle, with plate movement being limited by adjustable stop means to correspondingly limit the stitching length. Gauge means extending across the plate accommodates positioning portions of the work piece in a selected spatial relation to a reference line on the plate to control the location of the stitching as required in tacking, pleating, measuring and sizing of draperies.
