Abstract
The utility model provides a flat machine which can prevent the generation of yarn waste, enhance maintained freedom and shorten the length of end yarns. A suction mouth (39) is mounted between a yarn gripper (3) and a yarn gripper (4), provided with a suction port (39a) which is opened in the shape of a longer hole in the vertical direction, and can suck surrounding air from the suction port (39a). The attractive force is generated through the negative pressure generated in the way that compressed air is discharged to a dust collecting box (43) from a discharge mouth (42). When a knitting yarn is weaved and cut by a cutter (5) directly and the yarn gripper (3) and the yarn gripper (4) are released, the end yarn on the side of a knitted fabric can be shortened. The yarn gripper (3) and the yarn gripper (4) are shortened during the maintaining process of the knitting yarn, and the maintained freedom is enhanced. Although maintained yarns on the sides of the yarn gripper (3) and the yarn gripper (4) are turned into yarn wastes, the yarn wastes can be removed from the suction port (39a) by moving the suction mouth (39).
