Thermal binding machine
A thermal binding machine enables documents and documents to be bound . The result is similar to a book .
history
The technique of thermal binding has its origins in book production . Here paperbacks and magazines are usually held together with the so-called adhesive binding . Although this type of bookbinding was invented as early as 1895, it was not used until the 1940s. Hamburg Albatross Verlag launched its first paperback books using this technology in 1931. Shortly afterwards, in 1939, the technique was also used by the American Pocket Books publisher. This brought out a large number of well-known book titles in paperback with great success.
In 1940 the process was decisively improved by the DuPont company . Dupont now used a hot-melt adhesive instead of the cold-bonding process that had been common up until then, and thus achieved significantly more robust bonds. This technology was taken up by the manufacturers of today's thermal binding machines.
functionality
In principle, all paper documents can be bound. The specialist trade offers suitable devices and thermal binding folders in various standard sizes (DIN A6, A5, A4 etc.). Some companies also offer custom-made folders for the thermal binding machine.
For binding, the individual pages are placed in a so-called thermal binding folder. The back of the folder is covered on the inside with an adhesive . After switching on the device, the adhesive becomes liquid and bonds to the individual pages. More complex devices have a shaking function to achieve a better bond. This allows the adhesive to penetrate better between the individual pages. The duration of the process depends on the power consumption of the device and the strength of the portfolio.
After cooling down, the glue hardens again and the documents are firmly bound in the folder.
Depending on the manufacturer and size, a thermal binding machine can bind documents up to 500 sheets (80 g / m²).
construction
Simple thermal binding machines have a slot for inserting the prepared thermal binding folder. There is an electric heating plate in the bottom of the shaft. A switch is used to start the binding process. Some devices have a thermal switch that ends the binding process, others are time-controlled. The device signals the finished binding process via an acoustic or optical signal.
Devices with a vibration function also have a motor-driven bottom or side plate.
Many devices also have a holder for the finished but not yet cooled binding files.
