They are slitting equipment and slit materials such as plastic films, paper, and textiles. They use fixed knives to slit material into strips. Some slitting machines have a single blade, while others use multiple blades. The type of slitting method used depends on the thickness and composition of the material to be slit.
The main slitting methods include razor, score, and shear slitting. Each method can have advantages and disadvantages. Slitting line For example, razor slitting is the most economical but requires frequent blade changes to ensure a high-quality slit edge. It is also a very rigid method, which can cause frayed edges, stretched fabric, and other problems. Shear slitting, however, has close tolerances and is more accurate.
Slitting is a standard process in converting industries. To minimize waste, it is advisable to choose a slitting machine that can perform a variety of applications. This is because a wide range of materials can be slit, from thin plastic film to heavy substrates and adhesive tapes. Many slitting machines feature extensive automation, allowing for reduced labor. These machines also provide an excellent price-to-performance ratio, which makes them highly popular among customers.
Razor slitting is the most common method. This is the most economical slitting method and is usually employed when working with rigid materials. Using this method, the material is slit from an axial or a surface roll. But this can result in a bead or frayed edge if it needs to be done correctly. Several machines have monitoring systems that check the blades’ condition and the material’s twists.
Score slitting, or crush slitting, is similar to the razor method. However, the blades used in this slitting method are incredibly sharp. When they are moved through the material, the sharp blades crush it and sever the parts of the material. Several slitting machines use this method to slit plastic cores and unique metal webs.
Slitting and creasing machinery may be provided with a programming device that actuates the rollers 28 of the frames. Programming can be given for predetermined lengths of the strips to be slit or for the number of sheets to be cut. Other slitting equipment may be equipped with touchscreen controls and differential air shafts.
Slitting equipment may be equipped with a de-twister, which detects twists in the fabric and removes them. Another option is a blower, which opens the tubular fabric. And another choice is a padder, which removes twists from the fabric and allows it to be slit. Various applications require different machinery, and each application has specific goals.
A slitting machine is an essential part of a fabric finishing line. It is used after the hydro-extractor and after dewatering. Depending on the type of material, the slitting machine can slit it after unwinding the parent roll.
Slitting is a critical component of the AD Protex bag manufacturing process, and the machines are essential to producing huge finish rolls. The slitting equipment includes a heavy-duty recoiler, a multi-blade slitting station, and a multi-shaft rewinder.
