Patent number: 5392725Abstract: A sewing machine needle is manufactured without producing any burrs on a blade by subjecting the whole blade to die pressing. A needle blank (10) is subject to double swaging, resulting in it being formed with blade sections (14, 16). Then, the needle blank is formed with an elongated portion (22) for subsequently forming a clearance-above-eye above a needle eye. The die pressing permits both side surfaces of a long groove (28) to be spread so as to be spaced from each other at a predetermined angle, and permits the clearance-above-eye (40) and eye portion (33) to be formed. The sewing machine needle thus formed exhibits sufficient rigidity and provides an increased space between the blade and a sewing thread, resulting in a sewing operation being carried out stably and at an increased speed.Type: GrantFiled: January 7, 1993Date of Patent: February 28, 1995Assignee: Organ Needle Co., Ltd.Inventors: Yoshitsugu Takei, Tsutomu Kojima

Patent number: 5189966Abstract: A tufting machine has a plurality of needles, each needle having a pair of eyes and cooperating with a pair of loop pile loopers seizing loops of yarn from a respective eye. The needle has an elongated yarn receiving groove extending along the surface of the needle facing the direction in which backing material is being fed. Each eye opens into the groove for receiving yarn guided along the groove. The point of the needle is offset relative to the longitudinal axis of the needle so that the needle does not enter loops previously shed by the loopers when relatively high pile height fabric is produced. The loopers of each pair of loopers have bills which point in the direction the backing material is being fed, the bills converging in the direction in which they point. The loopers of each looper pair are laterally spaced apart and each looper of the pair enters a clearance above a respective eye for seizing loops of yarn presented through the eye.Type: GrantFiled: April 24, 1992Date of Patent: March 2, 1993Assignee: Spencer Wright Industries, Inc.Inventor: William H.
