An object of the present invention is to provide a manufacturing system and a method for manufacturing sheet-like structures. The manufacturing system of sheet-like structures contains a loosened portion forming apparatus by which plural loosened portions, which are substantially U-shaped, are formed on a cord member, and plural linear portions, which connect each of the plural loosened portions, are formed substantially linearly; and a sewing apparatus by which each of the plural absorbing members and each of the plural linear portions are sewn with a thread member.

This invention pertains to the art of methods and apparatuses associated with measuring and profile tools utilized in crafts, particularly in the design of quilts. More specifically, the invention provides an improved measuring tool that incorporates a variety of undulating profiles and is useful in the construction of quilts of other items of craftsmanship that incorporate non-linear, undulating, curving or wavy profiles.

A method of applying stitching to an interior component is provided herein. The method including the steps of: a) penetrating an outer skin layer, a substrate layer and an intermediary layer of the interior component with an awl to form a piercing therethrough; b) retracting the awl from the outer skin layer, the substrate layer and the intermediary layer; c) inserting a needle through the piercing through the substrate layer, the intermediary layer and the outer skin layer to grasp a thread positioned on the outer skin layer; d) pulling the thread through the outer skin layer, the intermediary layer and the substrate layer; e) looping the thread with a previous stitch passed through the outer skin layer, the intermediary layer and the substrate layer; f) advancing the interior component to another position; and g) repeating steps a-f until a predetermined amount of stitches are applied to the interior component.

A system and method for assembling a prosthetic heart valve, including a procedure for tightly wrapping fabric around a heart valve support stent having a highly contoured undulating outflow edge. A mandrel retains tension without manual assistance in a tubular length of fabric wrapped over the support stent, and includes relatively axially movable inner and outer clamping mechanisms and a pedestal tube on which the support stent rests. The clamping mechanisms include clamps that pull the fabric only in the support stent cusps. The mandrel assembly may be placed in a chuck of a sewing machine system for automatically forming the seam. A small shuttle with bobbin thread reciprocates within a channel inside of the support stent and cooperates with the sewing machine needle to form a lock-stitch in the fabric tube. The mechanization of the fabric covering procedure greatly enhances manufacturing throughput and reduces ergonomic strain on workers.

A template is provided that aids quilt member fabrication. More specifically, a template is provided for selective interconnection to layered fabric members wherein the template indicates the location for sewing and cutting individual fabric pieces that make up the layered fabric thereby yielding a composite quilt member.

A wearer selectable removably attachable promotional pocket cover comprises a single body unit generally arrow in shape including two modules: a cover module and an insert module continuously and seamlessly joined together. An attachment means enables the promotional pocket cover to be temporarily attached to and from a pre-existing garment pocket at will. Awareness, support, and spirit, are raised for a specific cause by utilizing the promotional pocket cover with a specific promotional adornment affixed upon the cover module. In addition, money is raised for a single and specific cause, whether it is a school sport's team booster organization, or a charitable organization, by selling the promotional pocket covers having a promotional adornment affixed thereon that is readily identifiable with that specific cause. A promotional pocket cover, pattern and method of construction, and method of installation and use are described and claimed.

A marking template comprising a planar body portion having a central aperture, and a plurality of sets of apertures in the body portion, each set of apertures located a predetermined distance from the central aperture which enable rectangular patterns to be marked on a workpiece.

A wound dressing comprising a layer in the form of a strip and comprising gel-forming fibers, the strip having longitudinal lines of stitches formed from a thread and transverse lines of stitches formed from a thread.

A sewing machine including a needle being supplied with an upper thread, a loop taker which accommodates a bobbin for a bottom thread, and a drive unit, which forces the needle to perform a reciprocating movement. The needle, during its movement and in cooperation with the loop taker, executes a stitch on a sewing material being advanced between the upper thread and the bottom thread. A take-up lever, for each stitch, pulls tight a knot being formed in the sewing material by the upper thread and the bottom thread in cooperation. The sewing machine further includes a thread transfer member supplying the needle with an upper thread with either a thread portioner or a friction braking assembly for friction braking of the upper thread. A switch switches between thread supply with the thread portioner or with the friction braking assembly. A control unit controls the thread supply from the thread portioner or, alternatively, controls the friction braking assembly.

A quilt design holding device comprising a non-woven fabric sheet with top and bottom surfaces both impregnated with a non-transferable dry tack adhesive. Printed on the front surface of the fabric sheet is a grid pattern made of perpendicularly aligned first and second straight gridlines spaced one-inch apart with a one-inch margin along the top, bottom, and side edges. Inches and feet are labeled in the one-inch margin along the top, bottom, and side edges of the grid. The top and bottom edges and two side edges of the grid are marked with indicia at ½-inch, ¼-inch, and ⅛-inch intervals. Optional diagonal guidelines are printed on the grid pattern to help temporarily align selected pieces of fabric used to make a quilt on the device for viewing.
