A sewing or looping device for closing a tubular knitted article includes a body, two needles, a yarn support, and a cutting unit; the body has two spaced bases, the two needles are pivotally connected to the first base, respectively, and pivoting movement paths of the two needles are orthogonal to each other, the yarn support has a first section adjustably disposed on one of the bases, and a second section extending along an axial direction. The cutting unit is pivotally connected to the base where the yarn support is located. A cutting direction of the cutting unit is parallel to the axial direction, and the sewing chain stitch is pulled to the cutting point by the hook member and cut thereat. The sewing chain stitch assumes a tensioned state when being pulled, which in turn allows the sewing chain stitch to be cut more reliably and easily.

A method of manufacturing a midsole for an article of footwear includes cutting a pattern of openings at least partway through a midsole with a cutting tool driven by an embroidery machine. An article of footwear includes a midsole defining a pattern of openings extending at least partway through the midsole. An inner surface of the midsole is contoured and the midsole includes upwardly-extending sidewalls. At least some of the openings extend relatively nonparallel with one another through the sidewalls and splay away from one another along longitudinal axes of the openings.

A positioning device for rotating a movable tongue seat is essentially provided with a pin and a pin hole between a movable tongue seat and a cutter seat for driving the movable tongue seat. Rotating the positioning member can drive the movable tongue seat to move to a corresponding position, so that the movable tongue on the movable tongue seat can be extended and retracted from the top of the seat in an optimal position, and can be reliably controlled.

Various examples are provided related to seamer systems and methods that can be used at the end of a sewing process to secure sewing medium in sewn material by creating a knot. Excess sewing medium can be removed after forming knot at the sewn material. A clamp can secure a portion of the sewing medium while allowing at least one element of the sewing medium to pass through the clamp. A material stabilizer can align the sewing medium to form the knot and sever the excess sewing medium after the knot is formed.

A sewing machine includes a needle plate, a feed dog configured to move a workpiece, a vertical drive mechanism configured to vertically drive the feed dog, a switch mechanism, a cutting mechanism, and an actuator. The switch mechanism is configured to switch from an active state where the feed dog is driven, by the vertical drive mechanism, above and below an upper surface of the needle plate to an inactive state where an upper surface of the feed dog is maintained below the upper surface of the needle plate. The cutting mechanism includes a blade configured to cut a thread at a position below the needle plate. The actuator is configured to commonly drive the switch mechanism and the cutting mechanism.
