Abstract: 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.

Abstract: In a surgical stitching apparatus for endoscopically performing sutures of tissue or vessels having a drive mechanism including concentric tubes with an operating handle structure at one end and a stitching head mounted at the distal end thereof, the stitching head includes a stationary and a movable mouthpiece each with clamping structures for engaging the tips of a needle each comprising movable and stationary halves with the movable half on the stationary mouthpiece being operatively connected to one of the concentric tubes and the movable mouthpiece being connected to another of the concentric tubes which is hand-operable by a movable handle on the operating handle structure, and the one concentric tube is operable by a pedal switch-controlled mechanism mounted on the operating handle structure for foot operation of the clamping structure on the stationary mouthpiece.

Abstract: A sewing machine needle receiving and transferring arrangement wherein a clamp device for the needle is provided in each of the needle bars so as to engage or disengage the needle with or from each of the needle bars. Such clamp device engages or disengages depending on the energized or deenergized mode of a solenoid.

Abstract: The invention relates to an apparatus for the automatic removal and supply of needles in needle boards intended for the densification of fiber webs or non-woven fabrics into needle felts in which, in conformance with a prior art method intended only to supply needles and a corresponding apparatus, the needle bores of the needle board are addressed individually, a needle is held available in front of each addressed open needle bore and this needle is driven into the open needle bore, with the tricks of the needles being oriented in the proper position for installation.

Abstract: A sewing machine capable of simulating hand stitching. The machine comprises a throat plate (101), a needle passage region (104) through the throat plate, a needle (2), upper and lower needle holders (4, 5) for driving the needle between a raised position lying wholly above the throat plate and a lowered position lying wholly below the throat plate, and thread-control drum and looper (9, 11) lying below the throat plate. A thread-guide tube (26) is located above the throat plate for guiding supplied thread so that a section thereof lies in a first thread path. A first clamp (33, 34) is operable to releasably clamp the thread adjacent to a free end thereof when lying in said first thread path.

Abstract: A button sewing apparatus comprising a button supply device, a X-Y mover, a stay button chucking device, a surface button chucking device, a surface button turning device, a presser foot device, a thread guiding device and a thread holding device. Button neck wrapping is performed in a manner closely simulating "hand" sewing. After sewing both a stay button and a surface button to a workpiece, a sewing table makes a circular motion while keeping a needle entry as the center, and a thread is slidably clamped and guided to pass through a guide hole tentatively formed underneath a needle such that the thread wraps firmly around the button neck.

Abstract: A method and apparatus for sewing cover halves together around a baseball core or the like. The method includes the steps of advancing first and second needles in one direction over an edge of a first cover half and under and through an edge of an adjacent second cover half. The needles carry first and second double threads through the second over half. The ball cover is then indexed forward and the first and second needles are advanced in an opposite direction over the edge of the second cover half and under and through the edge of the first cover half for carrying the first and second threads over the edge of the second cover half and through the edge of the first. Prior to the second step of advancing, the second thread is positioned between the first and second needles and above the first needle so that a regular herringbone stitch pattern between the first and second cover halves is achieved as the steps are sequentially repeated.

Abstract: The invention contemplates a hand-held and hand-operable stitching device capable of performing a stitching operation at substantial offset from the region of manual contact. The stitching is performed as a special filament-carrying needle is shuttled in a reciprocating cycle of alternated release and retention at corresponding needle-retaining ends of two arms having articulated connection remote from their needle-retaining ends.

Abstract: The shuttle of the tying device is of magnetic metal, at least at its extremities. Each extremity of two arms is fitted with an electromagnet for temporarily receiving and retaining the corresponding extremity of the shuttle. The electromagnets are energized in alternate sequence through circuits comprising switches which are actuated in synchronism with the forward and backward movements of the arms by means of stationary contact-studs.
