A bobbin winder creates tight and evenly wound bobbins for various applications. It maintains even distribution and tension while creating coils. It can be self-contained or connected to a production line with various features available. Hand winders are used for small projects, while automatic winders work with a motor.
A bobbin winder is a device that is used to create tight and evenly wound bobbins. There are numerous applications for a coil winder, ranging from home electronics projects to the commercial packaging of products typically sold on reels. Numerous companies make winders in all shapes and sizes, including equipment with a number of accessory options, and electronics enthusiasts sometimes build their own, as the mechanics of a winder are quite simple.
Making a coil is actually quite hard work which is why people tend to avoid doing it by hand if it is possible to do so. For materials to roll properly, they must be evenly distributed over a core, whether or not a layer of rolled material is being made, and the tension must also be uniform during the wrapping process. A bobbin winder is designed to maintain even distribution and tension as it creates coils to be even.
Some bobbin winders produce only one bobbin at a time, while others can wind a number of bobbins at once. The device can be self-contained, such as with a simple winder used to prepare electromagnetic coils that can be used as electromagnets or inductors, or it can be connected to a production line. For example, in a cable company, reels are part of the production line so that the cable can be packaged for transit and sale as it is made.
There are a number of features available with industrial reels. Some have automatic splicing capability, ensuring that the same amount goes on each spool with no waste. Many others also cut automatically when they sense a reel is the right size or weight. Also, a bobbin winder can interleave other materials in the bobbin. For example, some industrial wrappers may wrap sheets of foil, interleaving with paper or a similar material to protect the sheets in transit.
With a hand winder, the operator controls the winder with a hand crank, foot pump, or similar device. These devices are used for small projects, as a general rule, and it may take some practice to learn how to handle the device properly. Automatic winders work with a motor that turns the winder, in which case the user activates the winder when needed. Industrial equipment usually has a safety shutdown feature that shuts down the device if something goes wrong.
