摘要： [Purpose] To obtain a sewing machine comprising a device with which it is possible to easily perform a threading operation in which a needle thread is inserted into the needle hole of the sewing machine needle, wherein the sewing machine comprises a threading device configured so that the needle thread does not drop onto or coil around an operation part (operation part) of the operation lever of the threading device when a thread-hooking operation is completed before insertion of the needle thread. [Configuration] The present invention comprises: a needle bar 52; a threading shaft 53; a thread-holding tool 71; a threading tool 72 provided at the bottom end of the threading shaft 53; an operation lever 4 that has an operation part 41 and moves the threading shaft 53 up and down and rotates the threading shaft in the circumferential direction; and a cutting tool 93 for the needle thread n. The present invention is configured such that a needle thread guide member A, in which an inclined part 1 is formed that guides the needle thread n from the thread-holding tool 71 to the cutting tool 93, is provided between the thread-holding tool 71 and the cutting tool 93, and the inclined part of the needle thread guide member A guides the needle thread n that has been cut by the cutting tool out of the operation range of the operation lever 4.

摘要： A sewing machine is provided with a function of adjusting a thread margin remaining on a cloth side to be sewn to a desired amount. A sewing machine includes a cutting member and a thread length adjustment mechanism. The cutting member cuts an upper thread and a lower thread between a hole of a needle plate and the cutting member. The thread length adjustment mechanism adjusts the length of the upper thread and the lower thread extending from the hole of the needle plate up to the cutting member.

摘要： In a sewing machine, an elevating unit is configured to be integrally raised and lowered with a threading lever of a threading apparatus. Furthermore, an operating lever is coupled to a lever interlocking mechanism that interlocks with the rotational operation of the operating lever. Upon pressing threading lever downward from an initial position when operating lever is at an operating position, an elevating unit engages with lever interlocking mechanism. Operating force applied to threading lever is transmitted to operating lever via lever interlocking mechanism, thereby turning operating lever from operating position to non-operating position. Accordingly, even when a presser is at a raised position, by pressing threading lever downward, operating lever is turnable from operating position to non-operating position, thereby allowing presser to return to pressing position.

摘要： With a overlock sewing machine, when a switching mechanism is switched to a threading-enabled state, and a looper cover is closed, the looper cover is slid toward one side in the hinge shaft axial direction so as to operate a detection lever. In the non-operating state, the detection lever is set to an initial position where it does not press an operation protrusion of a switch. When a side cover is closed, and the detection lever is operated, the operation lever is set to an operation-enabled position where it presses the operation protrusion. When the operation lever is operated, and the side cover is opened, the detection lever is set by passing through the operation-enabled to the operation-disabled position where it does not press the operation protrusion.

摘要： A multi-needle threader for use in weaving hair extensions. The threader has an “L” shaped body for holding at least one spool of thread in proximity to a plurality of needles held in pin cushions. The needles and pin cushions are positioned on the threader such that the needles can be threaded in a sequence or order continuously one needle to another until all are pre-threaded for use and then the needles can be used in reverse order without unthreading any unused needles.

摘要： In an overlock sewing machine, a main shaft fixing operating shaft is provided with a differentiation ring that can be swung in a predetermined range such that, when the rotation of a main shaft is to be enabled, it is set to an enable state in a stationary state, and when the rotation of the main shaft is disabled, it is swung and shifted from the enable position. Furthermore, a looper cover open/closed detection configuration is configured by modifying a part of a typical known configuration. Such an arrangement provides an overlock sewing machine having a simple configuration that requires only a single micro switch to detect the switching between the threading mode and the sewing mode and to detect the open/closed state of the looper cover.

摘要： The present invention provides a threader of a sewing machine in which the entire head portion can be made compact and the operator can perform threading work with one hand. The threader comprises: a threading shaft approaching a needle bar for moving a supporting sewing needle vertically; a threading hook for moving a hook portion in and out of a needle hole; a positioning member for regulating a lowermost position of the threading shaft to a position where the height of the hook portion matches that of the needle hole; a first rotary mechanism for rotating by a predetermined angle near the lowermost point of the threading shaft so that the hook portion is inserted into the needle hole of the sewing needle; and a thread-guiding member for guiding the top thread to the hook portion at a near lowermost point of the threading shaft. The threader further comprises a second rotary mechanism for rotating by a predetermined angle so that a thread-catching portion of the thread-guiding member passes through the position of the needle hole of the sewing needle at a near lowermost point of the threading shaft, and the first rotary mechanism and the second rotary mechanism rotate the threading hook and the thread-guiding member in opposite directions.
