What’s a Slitting Machine? And what’s the Function of It?

The machine used for roll slitting is called a slitter rewinder, a slitter or a slitting machine – these names are used interchangeably for the same machines. Today, we will have a brief introduction to the function of slitting machine.

Roll slitting, also known as log slitting or rewind slitting, is a shearing operation that cuts a large roll of material into narrower rolls. By today’s definition, slitting is a process in which a coil of material is cut down into a number of smaller coils of narrower measure. Potential work pieces are selectively thin (0.001 to 0.215 in.) and can be machined in sheet or roll form. Slitting is considered a practical alternative to other methods due to its high productivity and the versatility of materials it can manage. Rewind slitting involves rewinding the material through a number of knives to form narrower rolls of materials.

When the term “slitting machine” is used to describe the machine, the three parts are referred to as the unwind, the slitting section and the rewind. Slitter rewinders are normally used to slit plastic films, paper and metal foils. The unwind is normally braked to maintain accurate tension in the material. Some machines have a driven unwind which reduces the effect of inertia when starting to unwind heavy rolls or when the material is very tension sensitive. The slitting section has three main options: Rotary shear slitting, Crush cut slitting, and Razor slitting which is ideal for thin plastic film. The rewind section also has options. The main type is centre winding using differential rewind shafts.

Roll slitting is a technique heavily used by Converters industry. The converter industry normally refers to companies who print, coat and laminate materials. A typical converter is a company manufacturing producing flexible packaging material for packaging food. This may involve purchasing large rolls of plastic film such as biaxially orientated polypropylene which is then printed to the customer’s design and coated with cold seal adhesive for use on high speed packaging machines. This material is printed and coated in wide, large diameter rolls for maximum efficiency. The rolls are then slit, using a slitting machine, into smaller rolls of the size to be used on the packaging machine.

We FeiYue Digital Technology Co., Ltd mainly manages sublimation paper, inkjet printer, digital printing inks, calendering machines and accessories, operating this industry has been more than 10 years experience. After continuous improvement of the product, to ensure product quality can also be profit at the same time to the minimum, to ensure that customers enjoy the best price and the best quality products.

Widely Application of Slitting Machine in Paper Processing Industry

slitting machineSlitter is an automatic die-cutting machine supporting products, this machine is suitable for narrow paper slitting. It has automatic meter, count, set length, quantity automatic shutdown, unwinding by photoelectric automatic rectification control functions. The slitting machine has the characteristics of compact structure, fast speed, high efficiency, accurate slitting, simple operation and stable operation.

Slitter is a broad paper or thin film into a wide range of narrow materials of mechanical equipment, often used in paper machinery and printing and packaging machinery. The former slitter (disk paper slitter) of the magnetic powder clutch speed can not be high, Slitter because in the operation of the high speed friction caused by magnetic powder, resulting in high temperature, shorten its life, serious will be stuck to die, Slitter so that the machine operation is blocked, to produce serious consequences.

Slitting machine is a wide Web paper slitting and rewinding to the width of the paper processing equipment. Widely used in paper processing industry or printing and distribution.

Performance and Characteristics:

1. Slitter is the use of microcomputer control, magnetic powder clutch tension control, the center of the method of coiling.

2. The host is using frequency conversion speed control. Slitter Can automatically meter, alarm shutdown. Tension digital display function.

3. Unwinding using photoelectric automatic rectification (or gas hydraulic rectification) correction system master, so that the irregular material can be divided into normal.

4. Round knife (or flat knife) slitting, waste edge automatic discharge device.

5. Manual (or pneumatic) discharge reel with cone sleeve type inflatable shaft (3″or 6″).

6. The rewinding adopts a, B axis (inflatable type).
