Abstract

A sewing machine includes a supporting plate portion and a needle. The supporting plate portion contacts sewing fabric that is moved in a predetermined direction during a sewing operation. The needle is vertically moved between a top dead center above the supporting plate portion and a bottom dead center below the supporting plate portion. The supporting plate portion has a needle hole through which the needle passes. The lower end opening of the needle hole is larger than the upper end opening.

Description

technical field [0001] The present invention relates to a sewing machine, such as a quilting machine. Background technique [0002] In a standard sewing machine such as a quilting machine, a needle plate (a sewing cloth support plate) and a vertically movable clamping plate (a sewing cloth support plate) supported on the needle plate are included. Needle holes of the same diameter are formed in each of the needle plate and the clamp plate. The positions of the pinholes correspond to each other. When a piece of cloth clamped between the needle plate and the clamping plate is fed, the needle threaded with the upper thread reciprocates vertically between the upper dead center above the clamping plate and the lower dead center below the needle plate, simultaneously through the pinhole. Thus, a sewing pattern is formed on the cloth. [0003] In order to meet the requirements of shorter sewing times, the feeding speed of the cloth in the sewing zone has been significantly incr...
