Connectors between and within objects in machine embroidery

Connector – connection (connection) of embroidery digitizing elements with each other or segments of one object within it.

Connectors can be of 3 options:

1)      Jogging – connecting objects (segments) of embroidery with a simple stitch (run).

2)      Jumps – there is no visible connection between embroidery objects.

3)     Broaches – a thread is drawn between the objects of embroidery from the end of one to the beginning of the other.

I’ll tell you briefly about each of these types of connectors.

Jogging

The run itself can be located both between separate objects of the same color and inside an object of a simple or complex branched shape.

In the picture below, the run goes from the end of one object to the beginning of another – this is a classic run between contours. The objects to be connected are at some distance from each other.

Usually, jogging is used when it is possible to hide the stitches under other objects that will be sewn later.

Jogging between objects of the same color aims to minimize the amount of trimming in the design and shorten the embroidery time.

Important: if the run is dark, and the top layer of stitches is light, then such a number will not work – the dark thread will shine through the light cover, and you will have to trim. You can also skip cropping, but do a jog with a distance between objects up to 1.5-2mm.

The jumps between segments of one object (travel stitches, under path) are presented.

Now, with the high automation of the programmer’s work, only the parameters of the runs are set by the programmer (length, location inside the object or strictly along the contour of the object, the size of the overlap of the segments on each other), and their path is calculated by the software.

The roots of jogging have manual punching when the software was not yet available. Then one complex object was divided into several simple ones, depending on the angle of inclination of the stitches. And a simple object, depending on the points of entry and exit into the contour, was divided into segments. The puncher connected all the resulting segments with simple stitches. These human actions became the prototype of our today’s automatic jogging inside the circuit.

Benefits of running over trim jumping

1) The machine runs faster

2) Fewer thread breaks and thread loss from the eyelet

3) Reduces embroidery time and increases productivity

Jumping

Jumping is a way of connecting objects to each other if they are at a distance and it is impossible to apply a run. Jumping is when the machine moves the hoop from one coordinate to another but does not sew (no stitches). Usually, before jumping, they set a trimming – a special software function for cars that have an automatic trimmer. When using such a connector, there are no threads between objects – everything is cut off.

As I wrote in a post about effective planning of the embroidery path, it is better to minimize the amount of trimming in the design, which will help to avoid thread breaks, needle breakage, and thread run away from the needle after trimming. Plus, the economic factor plays a significant role here: each trim adds 7 seconds to the embroidery time and is equal to embroidery about 65 stitches. That is, each new cut is a drop in productivity.

Broaches

In principle, broaches are the same as jumping. This is the same way of communication between objects that are at a distance from each other. But a thread stretches from the end of one object to the beginning of another, but there is no full-fledged line since the machine does not make punctures. This results from the fact that at the end of one object the trim function is not supplied.

This method of connecting objects in design is quick and convenient for programming – you don’t even need to think about whether cropping is needed here or not. But on the other hand, in my opinion, it creates problems after embroidery – the broaches have to be cut off. In addition, sometimes broaches are sewn under other elements that were embroidered later. And this is rather tedious work and is generally not profitable for production on the stream: too much time is spent on cleaning products.
