Is the base paper used in the test of the saw machine more suitable for splitting or trimming?

When it comes to testing a paper cutting machine, the choice between using a paper with a center cut or a trimmed edge can have an impact on the results. This is because the different types of paper offer varying levels of stiffness and smoothness, which can affect the machine’s ability to cut effectively.

The difference between slitting and trimming raw paper

Slitting: Slitting is the process of cutting wide paper rolls into several narrow paper rolls according to specific sizes and specifications. This processing method mainly focuses on the dimensional accuracy and edge neatness of the paper.

Trimming: Trimming is to trim the edge of the paper to remove irregular or damaged parts and make the edge of the paper smoother. This processing method pays more attention to the appearance quality and beauty of the paper.

When testing a paper cutter, choosing to use center-cut paper or edge-trimmed paper can have an impact on the results. This is because different types of paper have varying degrees of stiffness and smoothness, which affects the machine’s ability to cut efficiently.

When testing paper cutters, it is generally recommended to use medium-aged kraft paper with a center cutout. This special type of paper has a consistent thickness throughout, ensuring more reliable and even results during cutting. The advantage of a center cut is that it is less susceptible to jams or operational issues, helping the machine run smoothly.

Instead, testing your paper cutter with cut-edge kraft paper is also a viable option. This type of paper is smoother and more uniform in thickness than center-cut paper, making it suitable for evaluating a machine’s accuracy in handling complex cuts or irregular shapes. However, it is important to note that paper with cut edges may be more prone to jams, especially if the machine lacks proper calibration or maintenance.

Selection of base paper in sawing machine test

Production costs and efficiency
Slitting base paper: Since the slitting process can be directly cut according to the required size without additional trimming, the production cost is relatively low and the production efficiency is high.
Trimmed base paper: Trimmed base paper requires additional trimming, which increases production costs and processes, and also reduces production efficiency.

product quality
Slitting base paper: Slitting base paper has excellent performance in dimensional accuracy and edge neatness, helping to ensure the stability and consistency of cutting quality in sawing machine tests.
Trimmed base paper: Although trimmed base paper has improved in appearance quality and aesthetics, its cutting quality may be affected by edge irregularities or damaged parts in sawing machine tests, thus affecting product quality.

Slitting base paper: Slitting base paper is suitable for sawing machine tests that require high dimensional accuracy and edge neatness, such as high-precision cutting, automated production and other scenarios.
Trimmed base paper: Trimmed base paper is more suitable for application scenarios that require higher appearance quality and aesthetics, such as packaging, printing and other industries.

How to choose suitable base paper

Select the appropriate base paper type according to the specific needs of the sawing machine test. If the test requires high dimensional accuracy and edge neatness, it is recommended to choose slitting base paper; if the requirements for appearance quality and aesthetics are high, you can choose edge-trimming base paper. Consider production costs and efficiency. On the premise of meeting the test requirements, try to choose the type of base paper with low production cost and high efficiency. In the sawing machine test, the selection of base paper is crucial to ensure the smooth progress of the test and the quality of the product. Reasonable selection based on the specific needs of the test and the characteristics of the base paper can reduce costs, improve efficiency and ensure product quality.
