A system and method for capturing thread from an entraining air flow is provided, wherein the entraining airflow is selectively created in response to a location of the user relative to the device. The entraining airflow is sufficient to entrain an anticipated length of the thread, wherein the entraining airflow then passes through a grill. The grill shape, the airflow rate and the airflow velocity are selected to retain the entrained thread on the grill. The airflow is then terminated without requiring user intervention. Upon retention of a number of threads on the grill, the grill is separated from the housing and the retained threads are simultaneously disposed of in a desired container.

An embroidery device includes a needle including a hole through which a thread has been passed, a dyeing unit configured to dye the thread in different colors, an embroidery unit configured to move the needle to perform a sewing process on a medium with the thread dyed in the different colors by the dyeing unit, and a remover configured to remove the linear member in a vicinity of the needle.

An integrated system for treating a thread and using the treated thread, comprising: a thread treatment machine for treating a thread or portions thereof; a thread applicator configured for using the treated thread such as a stitching machine of 3D printer; at least one mechanism for collecting and trimming thread portions; and a control unit, configured for controlling at least the thread treatment machine, the thread applicator and the collecting and trimming mechanism and for coordinating the treatment of the thread with the operation of the thread applicator, wherein the control unit is further configured for controlling the collecting and trimming mechanism for collecting untreated thread edge portions for allowing using only treated thread portions.

A sewing machine includes a controller and a thread cutter which cuts an upper thread passed through a sewing needle and which has a fixed knife, a moving knife, and a driving source to drive the moving knife. The moving knife cuts the upper thread by guiding the upper thread. The moving knife has a through-hole into which the sewing needle is loosely insertable and includes a thread cutting portion in an inner edge portion of the through-hole. By controlling the driving source, the controller makes a stitch point of a first stitch of the sewing needle with respect to the through-hole of the moving knife, and moves the moving knife to a position where the fixed knife and the moving knife cut a sewing start end portion of the upper thread after a stitch point of a second stitch of the sewing needle.
