The starting material for the manufacture of springs – wire – goes to the block of winding springs, where she first rectified and then twisted into a spiral of a certain diameter, forming a template for future spring. Further, to give the necessary strength, harvesting fired. When the surface of the spring obzhoge also removes oil that could remain on it after twisting. After these operations, the spring is ready to zapakovke (Sealing of) in the case. When performing zapakovki, the spring is compressed and sealed in packaging material by means of ultrasound. The packaging material is made of special fabric (spunbond), or from elastic materials.
After this, ready to spring leaves packed area of packaging and can be used for the following operations of the independent production unit. Ready for connection between the springs is an independent unit, used another type of machine. At the entrance of the machine components are fed an independent unit – strips of packaging material sealed in it springs. In the future, perhaps as a parallel or staggered combination of these components. Feeds independent spring block stick together in the adhesive site of the machine, forming a block of a given length. This process is accomplished by several mechanisms, which feeds the adhesive, coating, distribution and fixation of the tape spring blocks, lining, etc. In order to avoid fluctuations in the block springs are tight to each other. In the end, after all operations on the receiving node of the machine comes ready independent spring block of a given size, which then form the basis of modern manufacturing mattress.
