Paper Tube And Paper Core Types
A spiral paper core making machine can produce a variety of paper tubes, paper cores, and related products. Paper tubes or paper cores can be made from one, two, or more layers of brown kraft paper or paperboard. The innermost layer or ply (liner) and the outermost layer (wrapping) can be made of different materials (foil, film, etc.) or specialty papers. Specialty papers and materials can provide waterproofing, graphics or labels, or specific colors. The two main types of paper tubes and paper cores include spirally wound paper tubes and coiled or parallel wound paper tubes. The paper layer or layers of a spirally wound tube are wound at an angle to the axis of the tube. In a coiled tube, the two outer edges of the paper strip are wound parallel to the axis of the tube or at a 90-degree angle.
Spiral Paper Core Making Machine Working Principle
Paper tube and paper core manufacturers use a variety of processes, including cutting, winding, gluing, and finishing.
Step 1: Paper Cutting
Cutting the paper to the appropriate length is the first step in producing a cardboard tube. Typically, kraft paper is a heavy and flexible material used to make paper. The decision to cut the paper by machine or by hand depends on the number of paper tubes to be made. The spiral paper core making machine unwinds and cuts large rolls of paper into narrow strips or layers, and then the stacks of paper or paperboard rolls are moved to the winder.
Step 2: Rolling the Paper
The paper roll is wound around the spiral paper core making machine shaft (a cylindrical tool) to form a tube. Metal or plastic mandrels can be used to make tubes of different diameters and lengths. For uniform straightness and precision, the paper is firmly wound around the mandrel.
Step 3: Tube Forming
The paper roll is wound around the spiral paper core making machine shaft and then glued to secure the paper roll. Use a glue gun or glue roller to apply glue to the perimeter of the paper. In most cases, the glue is a mixture of water and adhesives that helps hold the paper together and increase its durability.
Step 4: Cutting the tube
The longer tube is cut into the required shorter lengths for final use. The cut-to-length paper tube is cut into the required length and then enters the secondary finishing cutting and sealing process. You can also groove, slot, window cut, perforate, emboss, deburr, dust and polish or scrape the ends of the paper tube as needed.
Step 5: Forming
After applying the adhesive, the paper tube is left to dry. Depending on the adhesive, the drying time may vary from a few hours to overnight. After the adhesive is dry, the paper tube is removed from the mandrel and cut to size. You can leave the ends of the paper tube open or seal them.
Tube and core making
Tube and core making is a paper processing process that combines paper web slitting, paper web winding and laminating or gluing steps.
The number of paper layers that our spiral paper core making machine can process usually ranges from about 2 to 25 layers, but some spiral paper core making machines can even process up to 30 layers of paper. The number of layers is usually around 0.008 to 0.050 (0.2 to 1.3 mm). The number of layers ranges from 1 to 50 or more, but 3 to 25 layers are more common.
The thickness of the paper tube that can be produced is 2-30mm. If you need to customize the parameters of the paper tube, we can also customize a dedicated spiral paper core making machine for you. If you are interested, please contact us now!
