Plastic line hot stamping

The hot-spot of plastic line is a book binding method between wireless glue binding and sewing thread binding. It will have the advantages of two kinds of mature binding technologies, low-cost adhesive binding, and high-quality sewing. As one, and can be completed online with modern high-speed folding equipment. The use of plastic lines for hot-stamped signatures can be used for adhesive binding, and there is no need to mill the back of the book, which is a new staple of recent years.

The lock line is completed in the fold

The hot-skin of plastic line is completed in the plastic line hot-seal online unit of the folding machine. Before the final folding, the thread is threaded and a special heat-meltable plastic is inserted into the final crease of the signature. line. Afterwards, during the heating process, the sheet is folded and pressed, so that a plastic cord is melted by the feet to seal the signature, and then the sheet is attached, covered, hot-backed and pressed.

At present, there are two types of sewing lines for hot-stamped plastics. One is similar to the stringing principle of saddle-stitching. In the creases of the signature, the plastic thread is cut out from the inside out and cut off, leaving the thread on both feet. An outer book foot is formed and then heated at the footer. The plastic thread melts and folds with the book (the other foot stays on the outside to bond with the other book on the back of the book to make it more secure). Another method is to use similar sewing methods to sewn the plastic thread to the final crease, and start heating at the same time as the thread lock until the folded sheet is pressurized. The hot wire for plastic line is a kind of strand coated with hot-melt resin material. After being heated, it can be combined with the signature.

Plastic line ironing machine modular design

The technology of plastic line hot stamping was born in Germany in the 1960s. The development has become more and more sophisticated. Nowadays, the plastic line hot stamping equipment is mostly modular design, compact structure, save space, and do not have to increase the operator, can be with any group The folding machine is online, ie the last fold of the book page is completed on the plastic line ironing machine. Hot-folded folding methods include knife-folding and triangle-folding. At present, equipment suppliers who can provide plastic line ironing machines are mainly German MBO companies and Heidelberg companies.

Advantages of Plastic Line Hot Stamping

The hot-spotting of plastic lines incorporates the sewing technology into the production of glue and glue, greatly improving the quality of binding and production efficiency, especially for the headache-bound glue-bound book-laying pages. It is also “line-to-disease”. Gradually becomes the preferred binding method for dictionaries, albums, textbooks, calendars, and manuals, etc. Its main advantages are:

(1) The adhesive fastness of the hot-stamped plastic products can be comparable to that of hardcover books;

(2) After the hot-stamped plastic book is opened, it will be stretched flat and easy to read;

(3) The production cost is lower than that of the same quality staple glue adhesive products;

(4) The production process is reduced and the production efficiency is improved.
