Embodiment Construction

[0023] The sewing machine 1 has a base plate 2 with a column 3 and a curved arm 4 extending upwards from the base plate. The arm 4 terminates in a head 5 . An arm shaft 6 is rotatably arranged in the bending arm 4 , said arm shaft 6 driving a crank drive 7 with a thread take-up lever 8 in the head 5 . The crank drive 7 is drivably connected to a needle bar 9 movably arranged in the head 5 . The lower end of the needle bar 9 has a sewing needle 10 . The sewing needle 10 is driven by the crank driving device 7 to move up and down, whereby the sewing needle 10 passes through the needle movement area, which will be described in detail below. In the eye of the sewing needle 10 the needle thread 13 supplied by the bobbin 12 via the thread take-up device and the thread take-up lever 8 is guided.

[0024] On the base plate 2 is mounted a support plate or needle plate 14 on which a piece of fabric 15 is placed. The support plate 14 has a dog opening or needle plate recess 16 design...

Abstract

The invention relates to a sewing machine, which includes a needle plate with a needle plate recess and a needle rod connected with a sewing needle thereon, wherein, the needle rod is driven to move up and down above the needle plate. A transporter (17) is arranged in the needle plate recess and used for performing the transportation. The transporter (17) includes a transporting portion (28) which is designed to frictionally interact with sewing material and perform the transportation near a needle movement area. In addition, the transporter (17) includes a base portion, through which the transporting portion (28) is rigidly connected with a transporter bracket. A transporter wall (32) is arranged below the transporting portion (28) near the needle movement area. The transporter wall (32)is designed to extend at one side of the needle when the transporter (17) is mounted, wherein, the side is distant from a stitch formation tool interacting with the needle in the sewing process. The distance of the transporter wall (32) with respect to the needle movement area can be adjusted by means of an adjuster (33). Accordingly, a transporter and a transporter-mounted sewing machine are obtained with lowered likelihood of needle fracture and/or thread missing.

Description

technical field [0001] The present invention relates to a feeder for feeding fabric during operation of a sewing machine, said feeder comprising: at least one feed portion, which is located close to the needle movement area and designed for frictional contact with the fabric ground interaction and for performing the feed movement in the needle plate recess of the needle plate; the base body, through which the feed part is rigidly connected with the feeder support; the feeder wall, which is arranged on the Below the feed section and adjacent to the needle movement area, the feeder wall is designed so that when the feeder is installed, the feeder wall extends on the side of the needle away from the side that interacts with the needle during sewing. Stitch forming tool. The invention also relates to a sewing machine comprising a feeder of this type. Background technique [0002] A feeder of this type is known, for example, from JP 2004 / 174120A. [0003] During operation of t...
