While similar, digitizing for Multi-head embroidery machines can present its own unique set of challenges.\u00a0 However, one thing that is nice about evaluating a digitizing project on multi-head embroidery machines is this; regardless if the machine has 2 heads or 30 heads, if a problem is apparent on all sewing heads then the issue can almost certainly be attributed to the digitizing.\u00a0 If the problem only shows up on one head, but embroiders nicely on all of the other heads, there is almost certainly a mechanical issue on the head showing the failure.<\/p>\n
This might seem obvious but one of the first questions I will ask when presented with the question, \u201cwhy isn\u2019t this design sewing nicely on my machine?\u201d is, \u201care you embroidering on a single-head or multi-head machine?\u201d\u00a0 This is never meant as a method to shift responsibility from the programmer to a piece of equipment but it is really helpful to know the facts in order to provide the best solution to the problem. Embroidery quality is closely tied to the precision of the pantograph movement as well as the relationship between all of the other moving components on an embroidery machine.\u00a0\u00a0 An experienced programmer knows this and will often adjust a design to match the characteristics of a specific machine.\u00a0 One of the most frequent adjustment a programmer will make is to add a little more Pull Compensation to designs targeted for multi-head equipment.\u00a0 Since a multi-head machine needs to swing more mass when moving the pantograph, it may be necessary to compensate for this with slightly wider columns in areas with tighter registration.\u00a0 The machine manufacturers might say I am nuts to make this claim but I can state categorically from years of experience, for optimum performance it might<\/span> be necessary for a programmer to adjust a design even if two of the exact same multi-head machines models are sitting right next to each other on the same production floor running the same design. \u00a0This could also be true on a single head machine but it is easier to tune a design for a one head than a multi-head.<\/p>\n Poor programming will impact a single-head machine just as much as a multi-head machine but on multi-head machines those problems will be multiplied by the number of heads.\u00a0 Here are a few areas where poor programming can impact embroidery production.\u00a0 However, remember the test; if the problem is one head, it is probably the machine.\u00a0 If the problem is on all heads it is probably the digitizing. Trims<\/strong> \u2013 What is most important to determine here if the problem is with the stitch tie off which will cause a \u201cpull out\u201d or if the thread is actually breaking at the point of the thread trim.\u00a0 Digitizers use many different methods to tie off thread before and after a trim sequence.\u00a0 The techniques for this are too elaborate for the scope of this conversation but if you think you are getting \u201cpull outs\u201d (the thread pulls out of the needle in the trim process) instead of thread breaks, you should discuss tie off methods with your programmer.\u00a0 This phenomenon can also happen when the design starts sewing again in a new location.\u00a0 In this case, you look to the \u201ctie-in.\u201d\u00a0<\/p>\n Registration<\/strong> \u2013 Registration issues are when the border (be it walk, bean, satin, etc. stitch) do not \u201cregister\u201d with the area they are supposed to trap.\u00a0 This is an area that more times than not is related to the programming, but again see \u201cthe test.\u201d\u00a0 If this is happening on one head than look for things like bent needles, spoiled thread and poor tension.\u00a0 If this is happening on all heads your programmer needs to edit the design no matter what he might say.<\/p>\n Tension<\/strong> \u2013 There are a few symptoms which will manifest on both multi-head and single head embroidery machines that are rarely the fault of poor digitizing.\u00a0 These include: white thread showing on the top of the design and \u201cbird nesting.\u201d\u00a0 Both of these are related to tension and while a poorly programmed can aggravate the condition programming alone will almost never cause the problem.\u00a0<\/p>\n White thread on top of a logo (some people call this, salt and pepper effect) is caused by poor tension.\u00a0 What is happening (usually) is the top thread tension is too tight in relation to the bottom thread tension and the top thread will pull the bottom thread to the top of the embroidery.\u00a0 This is fixed by adjusting tension not editing your embroidery design.<\/p>\n Bird Nesting<\/strong> is the mother of all embroidery failures.\u00a0 It is characterized by an event where it looks like your embroidery head is trying to pull your entire garment through the needle hole in your throat plate and will destroy any garment that is unlucky enough to be on the machine when it happens.\u00a0 This problem is never caused by programming and is almost always caused by a failure of the bobbin case on your machine.\u00a0 Often times lint will build up between the tension spring and the bobbin case.\u00a0 When this happens, you cannot adjust the tension of the bobbin spring and the tension on the bobbin becomes so loose, the Bird nest is the result.\u00a0 When this happens, save yourself a lot of headaches and replace the bobbin case.\u00a0 Don\u2019t try and clean it.\u00a0 When this happens, the spring is sprung and there is no going back.<\/p>\n Programming for single-head embroidery machines and multi-head embroidery machines is fairly similar but there are \u201ctricks to the trade\u201d that seasoned programmer employ in order to facilitate the highest quality, production friendly designs. \u00a0This does not mean a design programmed for a single-head will not work on a multi-head or vice-versa.\u00a0 What it does mean though is if you really want to optimize your production environment you should have the conversation with your programmer about your exact equipment mix and ask him what he can do help you improve both the quality and efficiency of the designs that are produced by your equipment.<\/p>\n Steve Freeman While similar, digitizing for Multi-head embroidery machines can present its own unique set of

\nIf all heads on a an embroidery machine are in good repair and the machine itself is well maintained then in theory<\/span> it should not matter if there is one head or many.\u00a0 But the reality<\/span> of this universe is moving the mass of a multi-head machine\u2019s pantograph will induce some considerations the programmer needs to be aware of.\u00a0 Furthermore, some machines are simply better (higher quality pieces of equipment) than others.\u00a0<\/p>\n
\nThread breaks <\/strong>\u2013 Poor programming will cause thread breaks.\u00a0 However, the programming has to be really bad for this to be the case.\u00a0 What you would look for here is designs that are overly dense.\u00a0 If the stitches are packed in too tight thread breaks can be the result.<\/p>\n
