Abstract:
A threading device for threading line and the like into a desired opening or location includes a needle and a needle holder. The needle includes an area for connection with a line, and is held in place in a holder by permanent magnets or electromagnetic means. In use, the tip of the needle is inserted through the desired area, causing the tip of the needle to move away from the needle holder in the needle tip area while remaining connected to the needle holder in the needle base area. The needle tip returns to the needle tip area while next the needle base becomes separated from the needle base area, allowing the needle and line to be inserted through an opening, cloth or canvas. The threading device may be part of a fishing tool which may include a knot tying portion, line clippers, fishhook threading assistance region, or rotatable cover.
Abstract:
Disclosed is a needle threading machine of putting a thread through an eye of a needle provided in a sewing machine, the needle treading machine comprising a thread supplying unit supplying the thread along a predetermined thread guiding path; a thread catcher comprising a hook to hook the thread, and a hook supporter extended from the hook and supporting the hook; a thread catcher driver driving the thread catcher to reciprocate allowing the hook to be inserted in and return from the eye of the needle; and a thread guiding unit hooking the thread supplied from the thread supplying unit on the hook passed through the eye of the needle. Thus, the present invention provides a needle threading machine, in which a thread is stably hooked on a hook, thereby reducing a defective needle threading work and enhancing productivity .
Abstract:
Device (10) and method to automatically change the thread in a sewing needle on textile machines, comprising two or more feed reels (14) feeding two or more relative threads (11a, 11b) having a different characteristic from each other. The device (10) comprises a thread-change assembly arranged in substantial correspondence with a relative needle (12); each thread-change assembly includes cutting members (19) to cut a thread (11a) fed from a first reel (14), elements (22) that unthread the thread (11a) from the eye of the relative needle (12), elements (18, 20) that thread into the eye of the same needle (12) a new thread (11b), fed from a second reel (14), which has to start sewing, and clamping members (21, 29) to clamp the threads which are not in use in order to allow only the thread that has to start sewing to run.
Abstract:
A sewing machine which simplifies the engagement of a thread with a needle thread take-up lever and a thread tension regulator and the passing of a thread through a needle, and which has increased operating efficiency, comprising a take-up lever (25) and a thread tension regulator (9) which are disposed along a predetermine needle thread path extending from a thread bobbin (62) to a needle (19), a cassette mount (3) including a thread take-up lever travel region and formed in the form of a vertical groove in the arm head of the sewing machine, a needle thread cassette (2) having a thread bobbin (62) vertically received therein, which needle thread cassette is removably mounted on the cassette mount (3), a threading mechanism (10) installed in the arm head, wherein with needle thread (24) paid out in advance from the thread bobbin (62) substantially along the needle thread path to a position adjacent the needle (19), and in a state operatively associated with the operation for mounting the needle thread cassette (2), the needle thread (24) is engaged with the take-up lever (25) and the thread tension regulator (9) and the threading mechanism (10) passes the thread through a needle eye (19a).
Abstract:
In a device for feeding an upper thread (32) for an embroidering machine which is designed to feed a plurality of upper threads using a feed frame over a head (10) having a thread take-up lever mounted on a fixing board, the device includes: a vertical operating tube (14) and a fixed tube (13) provided between the head (10) and the feed frame for feeding the upper threads (32) a three-stage air valve; a cylinder operated in three stage by the action of the three-stage air valve; a conveying plate integrally formed with the overlying vertical operating tube and erected at the end of the three-stage cylinder (15), a thread-end fixing hook (151) made of a flexible spring material and formed at the front end of the thread take-up level (15) the thread-end fixing hook (151) being operative in connection with the cylinder; and a feed nozzle (40) provided as a pneumatic system for injecting a compressed air, wherein when the cylinder (16) is located at the utmost high position, the thread take-up lever (15) is moved to the rear of the vertical operating tube (14) and the feed nozzle (40) injects a compressed air to feed a desired upper thread; and with the vertical operating tube (14) ascending, the upper thread is hooked over the thread-end fixing hook (15) and moved to the front of the vertical operating tube (14), thus feeding the desired upper thread by the action of the head (10) and maintaining a tension of the upper thread to facilitate an embroidering operation.
Abstract:
An embroidery robot comprising a bobbin receiving section (22) capable of receiving a plurality of bobbins (21) disposed on the top of a sewing machine head (1), a thread adjusting mechanism (24) provided with thread tension adjustment mechanisms (25) and thread delivery mechanisms (28), whose number corresponds to the number of bobbins (21) receivable in the bobbin receiving section (22), and a thread selection mechanism (29) for selectively positioning the thread delivery mechanism (28) corresponding to a required bobbin (21) above a thread passing device (5) for passing a thread through a predetermined needle (10), wherein a thread delivery tube (28a) is disposed in the thread delivery mechanism (28) so as to lead the thread (10) to the thread passing device (5), and disposed at the lower end of the thread delivery tube (28a) is a thread sweeping and holding mechanism (28b) adapted to transversely sweep and temporarily hold a thread (11) drooping from the thread delivery tube (28a), so as to hold it by the thread holding member (31) of the thread passing device (5).
