Paper creasing machine - what it is and to <\/strong>What does it serve in the printing industry?<\/strong><\/h1>\n

A creasing machine is a device that plays a key role in the printing and office industry. It is used to carry out the creasing process, i.e. the folding of paper. In this article we will take a closer look at it and discuss the different types of creasing machines available on the market.<\/span><\/p>\n

What is creasing?<\/strong><\/h2>\n

Creasing is a bookbinding process that involves making a groove in paper. According to Polish standard PN-82, creasing is defined as \"making permanent indentations in thick bookbinding materials to facilitate their bending along an intended straight line.\"<\/span><\/p>\n

This process is essential when working with high grammage papers, usually from 150 gsm upwards. More and more printing articles, such as flyers, invitations, brochures and book covers, are made on papers with weights as high as 240-350 g\/m\u00b2. With such thick materials, folding without prior creasing can lead to serious problems.<\/span><\/p>\n

The problem with thick papers<\/strong><\/h3>\n

With high paper weights, a serious issue is the folding of such prints. Traditional folding methods have their limitations:<\/span><\/p>\n

    \n
  1. Cassette folding machines cannot fold such thick papers.<\/li>\n
  2. Stand-alone knife folders do not achieve the precision necessary for folding this type of work.<\/li>\n<\/ol>\n

    The only possible way is to fold after creasing the paper.<\/p>\n

    How does the creasing machine work?<\/strong><\/h2>\n

    A creasing machine is a device that is used to make precise folds on paper or cardboard. Creasing is the process of making a groove in paper. The imprinting of the groove changes the structure of the paper - the paper fibers are permanently bent, making them weaker and more susceptible to folding.<\/span><\/p>\n

    Two main methods of creasing can be distinguished:<\/p>\n

      \n
    1. Roll\/roll creasing<\/strong>: Consists of point pressing the creasing roll or disc against the paper.<\/li>\n
    2. Slat creasing<\/strong>: It is based on the simultaneous imprinting of the creasing strip over the entire width of the fold to be made.<\/li>\n<\/ol>\n

      Regardless of the method of paper creasing, the effect is similar - paper with a permanently imprinted groove is easy to break.<\/p>\n

      Advantages of creasing<\/strong><\/h3>\n

      Bigging eliminates a very serious problem commonly referred to as \"paper cracking,\" which is actually cracking of the paper coating or cracking of the ink or toner on the paper coating. The problem of cracking is usually seen with paper weights above 150 gsm. It is especially visible with dark colors - then the dark image contrasts with the cracked structure of the white paper.<\/p>\n

      Creasing methods<\/strong><\/h2>\n

      There are various methods of obtaining creasing:<\/p>\n

        \n
      1. Application punch<\/a>, followed by die-cutting - a method that can be used for high volumes.<\/li>\n
      2. Using creasing discs, such as on folding machines or cutting plotters.<\/li>\n
      3. Use of manual, semi-automatic and automatic slat creasing machines.<\/li>\n<\/ol>\n

        Paper scalloping is also essential in the processes of making covers for soft bindings.<\/p>\n

        Types of creasing machines<\/strong><\/h2>\n

        There are many types of paper creasing machines available on the market to suit different needs and scale of production. In our offer <\/a>you will find a variety of models, from simple manual creasing machines to advanced automatic devices.<\/p>\n

        Manual creasing machine<\/strong><\/h3>\n

        Manual creasing machine is the simplest solution, ideal for small offices or home use. It is used for occasional creasing of small quantities of documents.<\/p>\n

        Semi-automatic creasing machine<\/strong><\/h3>\n

        Semi-automatic creasing machines, such as. Swift 335<\/a>, are a popular solution in many printing houses. They allow comfortable work with print runs of up to several hundred pieces.<\/p>\n

        The operation of such a machine consists of:<\/p>\n

          \n
        1. Enter creasing parameters (usually the distance from the face of the sheet)<\/li>\n
        2. Performing the test<\/li>\n
        3. Placing more sheets under the rollers, which automatically carry out the creasing process<\/li>\n<\/ol>\n

          Automatic creasing machine specification<\/strong><\/h3>\n

          For larger print runs, an automatic creasing machine is ideal. Such a device has a feeder that takes sheets from the stack, which significantly speeds up the process and minimizes the operator's work.<\/p>\n

          Features of the automatic creasing machine:<\/p>\n
