Abstract

To respond to a request for downsizing of a cylindrical bed by improving a feeding means to give a feed to a sewing fabric on a needle plate. The sewing machine has a feed roller arranged in a partially exposed state on the upper portion of the rear side of a needle plate installed on the top face of a cylindrical bed, and intermittently driven around a shaft along the rear edge of the cylindrical bed, and pinches a sewing fabric with a pinch roller rollingly contacting the upper portion of the feed roller, and gives a rearward feeding to the sewing fabric sewn between a presser foot and the needle plate by the intermittent rotation of the feed roller.

Description

technical field [0001] The present invention relates to a sewing machine which is used for sewing a cylindrical sewn product and has a narrow cylindrical base which can be inserted as a sewing object. Background technique [0002] In order to be able to sew cylindrical sewing products such as cuffs and necklines of various clothing items, sewing machines with a cylinder bed (Cylinder Bed) with protrusions arranged on one side of the base body have been used since the past, so-called cylinder sewing machines. . [0003] In this type of sewing machine, the object to be sewn is inserted through the cylindrical base from the top end, is held by a needle jack plate (Stitch Plate) erected on the cylindrical base, and hangs down from the top end of the sewing machine casing. It is sewn between the Presser Foot. This sewing is performed by moving the needle hanging down from the top of the sewing machine casing together with the above-mentioned press plate relative to the needle d...
