Description

Machine process for creating breakthrough embroidery There are Process known, breakthrough embroidery for decorating any type of linen either As a wrap a jour alone or in combination with flat and eyelet embroidery or cord work as well as hemstitching or inserts and folds by threading the fabric and subsequently Sewing by hand.

It is also known to make winding a jour by lining up hemstitching produced by machine. It is necessary that as in the previous procedure the longitudinal threads are pulled out of the fabric by hand and the remaining Ouer threads can be sewn in tufts using a machine. This procedure is also supported by the the necessary thread-pulling by hand is very time-consuming.

Furthermore, the production of winding is a jour on the embroidery machine known. As is well known, the embroidery machine works with a needle that follows a Direction either across or parallel to the machine. The sewing thread will while doing a double stroke of the machine between the two through the needle stitch holes created. By shifting the fabric by hand after each A breakthrough is achieved with a double lift in the desired width. This method requires great attention and skill in operating the machine, but the work achieved on uniformity and cleanliness even with the best Operation of the machine can make no claim.

Finally, another method is known through the production of lap ä jour on series machines. Two machines are required for this process, whereby one machine the thread in the transverse direction and the other in the longitudinal direction sewn so that the rectangular sewn openings are created with both machines. This procedure is also cumbersome and especially for smaller decorations in unsuitable for larger dimensions.

All of these procedures are very cumbersome and time consuming. Also is the work thus achieved, especially with the various combined machine tools The process is extremely clean and uneven and not permanent.

The method of the present invention represents a substantial simplification compared to the known process for the production of winding a jour, the Work on the procedure through uniformity, clean appearance and durability identifies itself. What is essentially new about the invention is the machine processing of the sewing thread with a needle and a looper, the sewing thread at a complete Operation across and parallel to the machine, i.e. at right angles to each other, is sewn without shifting the fabric in any transport direction. In the accompanying drawing shows the subject matter of the invention.

Fig. I shows an operation of the needle bar carried out at a right angle an embroidery machine with the necessary sewing stitches.

Fig. 2 shows the sequence of several operations of the needle bar an embroidery machine in two rows of patterns on a greatly enlarged scale.

Fig. 3 shows a work completed according to the procedure.

Fig. 4. shows the sequence of the individual stitches and the course of the thread some operations of the needle bar of an embroidery machine in a pattern row a fabric shift parallel to the machine to the right.

Fig. 5 shows the sequence of the individual stitches and the course of the thread some operations of the needle bar of an embroidery machine in a pattern row a fabric shift parallel to the machine to the left.

The number and sewing direction of the individual sewing stitches, e.g. for a Shifting of fabric to the left is shown in Fig. I, the diagram of which shows an operation of the machine, for example five stitch movements of the needle bar of a beading machine represents, the thread through the sewing needle of the machine with the in two perpendicular mutually standing directions swing-out needle bar of an embroidery machine is sewn at an angle in the course of the individual stitches. The fabric needs at not to be postponed to such an operation.

Only at the beginning of the next work step is the By machine or by hand. The shift can be transverse or in the longitudinal direction of the machine, with the shifting of the fabric can be done automatically by the machine in one of the two directions, while shifting the fabric in the other opposite direction is best made by hand or by an adjusting device after a certain division can be.

The sequencing of several work steps and series of samples with This is shown by the individual sewing stitches in their sequence and line-up Diagram (Fig. 2), with the distance of each stitches of any size can be accepted.

The order of the individual stitches with different material transport (to the left or right parallel to the machine, fig. q. and 5) is after each of these Directions different. If the fabric is shifted to the right, it turns into two directions perpendicular to each other swing-out needle bar of an embroidery machine (Fig. D.) A stitch i, swings sideways, does stitch 2, swings back to the Stitch i, makes stitch 3, swings out perpendicular to the previous swing, makes stitch 4., returns to stitch i, makes stitch 5, whereupon the machine does shifts the workpiece to the right by one stitch length and repeats the operation until a pattern row of any length is completed. The workpiece is then Shifted by hand by a row width across the machine and the entire operation in the opposite direction with a machine shifting the fabric to the left repeated, the order of the stitches as shown in Fig. 5. It does this the needle bar that can be swung out in two mutually perpendicular directions an embroidery machine by this transverse adjustment from the last stitch 5 at a distance the row width the new stitch i, z. B. Fig. 5, swings forward parallel in Longitudinal direction of the machine, makes stitch 2, swings back to stitch i and does stitch 3, swings out perpendicular to the previous swing and does the stitch q, swings back to the first and third stitch and makes the stitch 5, -, before the machine moves the workpiece again by one stitch length until the second row of patterns following the first row of patterns in any length is accomplished. The workpiece can then be adjusted manually or by means of an adjustment device be shifted by a row width and the work process under machine Repeat shifting the fabric to the right as shown in Fig. 4.

The stringing together of several rows of patterns can also be done in this way that all rows of patterns are parallel to the machine due to the shifting of the fabric to the right or to the left by shifting the fabric parallel to the machine be generated.

The lining up of several rows of patterns then results in a desired one Breakthrough, e.g. B. according to Fig. 3.

Claims (2)

PATENT CLAIMS: i. Machine process for creating breakthrough embroidery (Wrap a jour) as a surface pattern, characterized by the following features: The in two mutually perpendicular directions swingable needle bar one Embroidery machine with a hook makes a stitch, swings sideways, does that second stitch, swing back to the first stitch, make the third stitch, swing perpendicular to the previous cut -, vibration off, make the fourth Stitch, returns to the first stitch, makes the fifth stitch, whereupon the machine shifts the workpiece by one stitch length and repeats the process, until a pattern row is completed; the workpiece is then made by hand or by an adjusting device shifted by a row width and the entire work process repeated, the needle bar with the needle at the stitch length of the last made fifth stitch from again making a first stitch, perpendicular to this shift swings out and makes the second stitch, swings back again to the first stitch and makes the third stitch, then swings out perpendicular to the previous swing and takes the fourth stitch, returning to the first and third stitch, and the fifth Stitch makes, whereupon the machine shifts the workpiece again by one stitch length and the process is repeated until the second row of patterns is of the desired length has joined the first; the workpiece is then manually or by a Adjusting device shifted again by a row width and the operation repeated. 2. Machine method for producing breakthrough embroidery according to claim i, characterized in that the pattern rows are generated transversely or parallel to the M 1 machine will.
