摘要： An overlock sewing machine includes: a looper cover detection member movable from non-switching to switching positions with looper cover open to closed state transition, with switching member operation switching the threading mechanism state to sewing-enabled after looper cover detection member movement to switching position; a side cover detection member movable from non-detection to detection positions with side cover open to closed state transition; and a lever coupled to the looper cover detection member and side cover detection member, switchable between states of pressing and not pressing the operating protrusion, following looper cover detection member and side cover detection member operating states. The lever is set to the pressing state upon movement of the looper cover detection member to switching position and of the side cover detection member to detection position.

摘要： A thread inserting device includes a guide pin having a thread capture portion at its tip for capturing a thread; a holder that fixedly holds the guide pin; a main body (first and second main bodies) slidably mounting the holder; and a thread cutting portion provided to the main body for cutting the thread to a length equal to or smaller than the protrusion of the thread capture portion from a thread captured position on a thread tip 6a side after the thread is captured by the thread capture portion. By shifting the holder, the thread capture portion is protruded to a predetermined length from the main body, and the thread cut to a predetermined length by the thread cutting portion is inserted into the thread inserting hole.

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： 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： An object of the present invention is to provide an embroidery cloth presser which prevents a needle thread from being sandwiched between the embroidery cloth presser and a cloth to allow an embroidery frame to move smoothly and which also prevents inappropriate draw-in of the needle thread, that is, prevents a cross-over thread of the needle thread resulting from long-distance movement of the embroidery frame from remaining on an embroidery surface. An embroidery cloth presser is installed on a presser bar of a sewing machine to press a cloth to be embroidered and which includes a projection provided on a bottom surface of the cloth presser which contacts the cloth around a needle and forming, between the cloth presser and the cloth, a gap through which a needle thread passes.
