A top feeder arrangement for a sewing machine provided with a processor for controlling stitches sewn on a cloth, wherein the sewing machine has a sewing machine head which comprises a needle mechanism with a needle bar (1) provided with a needle (2), a presser bar (3) provided with a presser foot (4) and a top feeder arm (10) provided at its lower end with a top feeder (11) acting from an upper surface of a cloth for feeding the cloth in the sewing direction and wherein the sewing machine is provided with a mechanism (12, 15, 17, 18) providing a controllable pressure of the top feeder (11) against the cloth.
The invention relates to a mechanically operated presser foot lift arrangement (2) comprising a presser bar (14) with a presser foot (15) and a presser foot lift (16) having a body (17) and a handle (18). The body (18) comprises a guiding means (21 ). An actuating means (23) connected to the presser bar is arranged to be guided along the guiding means on rotation of the body about a shaft (19). The guiding means cooperates with a first locking means (26) for locking the actuating means in a position corresponding to a first lifting height of the presser bar. The arrangement comprises also a displaceable means (27) having a second locking means (28), which may be brought into and out of cooperation with the guiding means. When positioned in cooperation with the guiding means, the second locking means is arranged for locking the actuating means in a position corresponding to a second lifting height of the presser bar.
A sewing machine (1 ) has access to a memory (M) for stitch data and a processor (C) for reading said stitch data and for operating the sewing machine (1 ) to execute stitches according to stitch data, wherein the sewing machine (1 ) has a hoop (20) for framing a pattern of the sewing material (2), and for moving the framed pattern in a direction comprising a component of at least one of a first coordinate (x) and a second coordinate (y) and wherein further the processor (C) controls movements of the hoop (20) according to said direction in relation to the position of a needle (5) of the sewing machine and synchronously with the movement of the needle for executing stitches, wherein: - the stretched sewing material (2) is clamped to the hoop (20) for forming a framed pattern in the hoop, - the framed pattern of the sewing material (2) is scanned by means of a camera (10) mounted in the sewing machine (1 ) and directed towards the sewing material (2) for the purpose of taking pictures of part views of said framed pattern, - said part views are tiled together for forming on a display an image of the pattern framed in the hoop, whereby a coordinate of the image of a display (11 ) refers to a corresponding coordinate of the pattern framed in the hoop (20).
