A method is provided for embroidering embroidery elements by means of a processor-controlled sewing machine (). The method includes: the fabric () that is to be embroidered is placed in the required position in relation to a threaded needle () on the sewing machine; a plurality of embroidery elements (A, B, C) in the form of software products having pre-programmed embroideries are provided; a group of said embroidery elements, defined as stitch data objects in a memory (M), is selected; an arbitrary curve (KU) along which said group of embroidery elements (A, B, C) shall be embroidered on said fabric () is defined by the operator of the sewing machine; said embroidery elements of said group are distributed in a spaced relationship along said curve utilizing a positioning algorithm. According to the method of the invention, a coupling between the embroidery elements of the group and the arbitrary curve is preserved during the full processing by said positioning algorithm.

Positioning of stitch data objects

A sewing machine () has access to a memory (M) for stitch data and a processor (C) for reading said stitch data and for operating the sewing machine () to execute stitches according to stitch data, wherein the sewing machine () has a hoop () for framing a pattern of the sewing material (), 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 () according to said direction in relation to the position of a needle () of the sewing machine and synchronously with the movement of the needle for executing stitches, wherein: &#x2014;the stretched sewing material () is clamped to the hoop () for forming a framed pattern in the hoop, &#x2014;the framed pattern of the sewing material () is scanned by means of a camera () mounted in the sewing machine () and directed towards the sewing material () for the purpose of taking pictures of part views of said framed pattern, &#x2014;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 () refers to a corresponding coordinate of the pattern framed in the hoop ().
