Definitions

• the method on which the preamble of claim 1 is based serves to embroider a succession of individual embroidery characters arranged at a distance from one another.
• JP-PAS JP-PAS
• a transition stitch is made in the lower part of the embroidery characters when changing from the embroidery end of one to the start of the next embroidery character.
• the length of this connection stitch depends on the position of the end or beginning of the successive embroidery characters.
• the position of the respective connection stitches is optimal for certain combinations of characters, for example, the leftmost embroidery stitch as the starting stitch and the rightmost one
• Embroidery stitch is defined as the end stitch. In the case of a different combination of the character string, however, such a requirement results in an unnecessarily long connection stitch between some characters. In addition, such a definition of the start and end embroidery stitches does not always result in an optimal execution of the stitch execution of the embroidery character in question.
• the invention is therefore based on the object of automatically shifting the connecting stitch from embroidery characters to be embroidered one behind the other to an embroidery-favorable location. According to the invention this is solved by the feature specified in the characterizing part of claim 1.
• the length of the connecting stitch between two successive embroidery characters is reduced to the shortest distance between these characters, so that the execution of the embroidery is accelerated.
• the recognizability of the individual characters is so little impaired by the connecting stitches that these usually do not have to be removed after the finished embroidery design.
• FIG. 4a shows an initial embroidery area of the character according to FIG. 3 with different initial key points, Fig. 4b - d different, at the respective
• End stitch point adapted stitch sequences of one of the end embroidery area of the character according to FIG. 3.
• connection stitch between two embroidery characters (Z) has a relatively large length in the vast majority of character combinations. This is particularly true when the string connected together on its base line is embroidered on an inner circular arc.
• the embroidery machine with which the embroidery characters (Z) are embroidered has a memory in which each embroidery character (Z) is predetermined by a large number of stitch control data.
• the stitch control data is contained in a separate data block for each embroidery character (Z). They are stored in the order of the needle entry points (PO, Pl, ..) to be carried out during embroidery in the data block assigned to the respective embroidery symbol (Z).
• the embroidery machine has a computing device for reading out and changing the stitch control data and a control device for controlling a workpiece holder in accordance with the stitch control data read out, this triggering a movement of the workpiece holder which moves it under the needle of the automatic machine so that the needle is successively inserted into the successive needle insertion points (Pl, P2, ..) of the embroidery symbol (Z) can pierce the embroidery design.
• stitch control data for starting stitch points (A0, AI, ...) are provided in front of the stitch control data that control the first needle entry point (PO) and thus form the beginning of the pattern Start embroidery area (A) are arranged.
• end stitch points (E0, El, ..) arranged at a distance from one another can also be defined.
• End embroidery area (E, E ', E' 1 ) In an end embroidery area (E, E ', E' 1 ) of the embroidery character (Z), end stitch points (E0, El, ..) arranged at a distance from one another can also be defined.
• end stitch points (E0, El, ..) arranged at a distance from one another can also be defined.
• end stitch points (E0, El, ..) arranged at a distance from one another can also be defined.
• End stitch points (E0, El, ..) In order that the execution of the embroidery at these end points (E0, El, ..) can be ended without impairing the execution of the embroidery symbol (Z), it is necessary to change the embroidery sequence in this for each different end point (E0, El, ..) End embroidery area (E, E ', E' 1 ) must be provided.
• 4b to d show the embroidery sequence at different end stitch points.
• 4b shows a normal embroidery sequence of the end embroidery area (E), the embroidery being carried out continuously from the needle insertion point (Pm) to the end embroidery point (E0).
• the end stitch point (E1) is placed in the middle part of the embroidery area (E ').
• the embroidery area (E 1 ) is divided into the sub-areas (el and e2).
• the partial area (el) that ends with the needle insertion point (Pno) is produced first. This is in the area of the end point (El).
• straight stitches are made up to the lower end of the partial area (e2), which is then embroidered from the needle entry point (Pn4) up to the end stitch point (El).
• FIG. 4d shows an embroidery design in which the end stitch point (E2) is at the top
• End of the embroidery area (E '') is provided.
• a straight stitch is carried out from the needle entry point (Pm) of the embroidery area (E '') to the needle entry point (Pm7) at the lower end of the embroidery area (E 1 1 ), after which it is embroidered up to the end stitch point (E2).
• the computer determines that final stitch point (E0, El, ..) of the preceding embroidery character (Z) and the starting point (A0, AI, ..) of the following embroidery character (Z) before executing two embroidery characters (Z).
