The continuous roll of paper that is fed into the machine is cut to length with a cutter, so that each length can function as an individual body panel on the bag. This cutting process is closely monitored by the photo eye, which automatically corrects and length errors, ensuring the cutting precision. Equipped with a Siemen's PLC system, along with an adjustable double template mechanism, ensures this paper bag making machine will always run in peak condition, while reducing time needed to adjust the bag size.

With a specially designed gathering platform, the finished paper bags are collected and are counted. The counting function makes it easier to pack the specified number of bags into bales, improving the packing efficiency. Machine operators appreciate the processes and fast speeds delivered by the Fangbang paper bag machine, and it is widely used in batch production operations in food and apparel industries.

Sample
Listed below are a few paper bags manufactured by our fully auto roll-fed square bottom paper bag machine. Please be aware that this machine can automatically make paper ropes to use as handles for these bags.

Features

  • Two templates are used to make the body panels, and they are symmetrically arranged so as to allow easy adjustments. Instead of changing the template in and out to make different sized bags, the patented double plate mechanism permits effortless template adjustment to match the new size. This reduces changeover times and improves production yields.
  • With a touch screen, users can change the length of the paper to be cut. An advanced Siemens PLC system maintains the overall control of the entire bag production system.
