ABSTRACT:
A sewing machine is provided for splicing together two different threads. The machine includes a thread tree with a number of thread spools with each thread thereof being inserted through flexible plastic tubing. A movable carriage assembly locates the new thread to be spliced relative to a splicing device passageway that receives the new thread to be spliced along with the old thread. The splicing device includes a front air inlet for drawing the new thread into the passageway of the splicing device and a rear air inlet for creating air turbulence during the splicing operation. Also used in moving the new thread through the passageway is an insertion drive roller connected to a pivotal rocker. A thread clamp cover connected to the rocker cooperates with the trimmer blades to trim the old thread. A thread clamp and a thread clamp magnet cooperate to hold the old thread in a desired position during the insertion of the new thread into the splicing device. A tensioning assembly is able to adjust new thread tension based on a desired tension for the new thread.
