An attachment for a sewing machine to provide simultaneous sewing and sealing of a seam comprises a reel for dispensing a strip of adhesive thermoplastic polymer between fabric members to be sewn. A plurality of heated driven rollers opposed to heated idler rollers having a continuous belt thereover collectively exert heat and pressure on the seam, melting the polymer strip so as to seal the seam. Thread having been treated with adhesive thermoplastic polymer may be employed to seal the punctures in the fabric made by the sewing machine's needle. The driven rollers are driven in synchronization with the operation of the sewing machine, and are engaged with and withdrawn from the seam responsive to operator command.

A system for English Paper Piecing and paper piecing quilting projects comprised of using pre-cut individual pieces of nonwoven batting having selected shapes and sizes as foundation pieces for creation of the patches used in the paper piecing project.

A strip is fastened to an edge of a textile piece by first advancing strip of the ribbon in a direction parallel to the strip of ribbon from a supply. Then a leading end of the strip is gripped a first nip point while advancing additional ribbon from the ribbon supply. The strip is then gripped at a second nip point upstream of the first nip point at a trailing end of the strip. The ribbon is then severed upstream in the strip-travel direction of the second nip point to separate the strip from the ribbon into a sufficient length between the first nip point and the second nip points. The leading or trailing end is then pivoted about at least one pivot axis relative to the other end and positioned near or on the other end, which is then fastened to the edge of the textile piece.

A belt loop for women's clothes and a method for sewing the same are proposed, wherein a belt loop has a structure in which both ends of the loop including multi-strand twisted yarns are connected to an integral piece or separate pieces of cloth for sewing, so that, when the front and back parts or the top and bottom parts of a garment are sewn with each other in a garment manufacturing process, the piece(s) of cloth for sewing can be sewn together therewith, and thus the belt loop can be formed simultaneously with the garment manufacturing process, which leads to process simplification and garment manufacturing cost reduction.

The present invention provides a system and method for the application of a functional thread to secure roving or other fibers to a substrate, thereby forming a precursor to a resultant composite component structure having targeted, enhanced structural reinforcement. The functional thread may be comprised of one or more fibrous filaments or have a monofilament structure. The invention encompasses the sewing of this functional thread at varying stitch densities as function of component stress analysis, the mechanical stresses that the component will be subject to when exposed to the forces and loads associated with its intended use, and at least one physical or mechanical property of a functional thread. This variable stitch density serves to provide targeted, localized mechanical enhancement and reinforcement to the resultant composite structure.

A presser device includes an attachment body, an adjustment member, and a presser body. The attachment body includes an attachment portion and a shaft. The attachment portion is attached to a presser bar included in a sewing machine and extending in a first direction. The shaft extends in a second direction that intersects the first direction. The adjustment member is configured to be screwed together with one end of the shaft and to rotate with respect to the shaft around a rotation axis extending in the second direction. The presser body includes an insertion hole and an insertion portion, the insertion hole penetrating in the first direction. The insertion portion is configured such that the shaft is inserted therethrough. The presser body is configured to move in the second direction with respect to the attachment body along the shaft in accordance with the rotation of the adjustment member.

A method of manufacturing an upper for an article of footwear includes dispensing ribbon in an overlapping pattern of ribbon sections to form a ribbon structure; and fixedly attaching a first ribbon section to an underlying material with thermal joining.

An article of footwear with an upper including a ribbon structure is disclosed. The ribbon structure comprises ribbon sections running in at least two different directions. Ribbon sections are connected at nodes. Between nodes portions of ribbon act like links joining the nodes. The links can be arranged in various geometries, including a rectangular grid and a triaxial grid. The ribbon structure may extend the entire length of the article of footwear, and may extend through a forefoot, midfoot and heel.
