Roll-fed Block Bottom Paper Bag Machine, Flat & Satchel Paper Bag Machine
As an important model in our series, the BW-292 automatic envelope-making machine is used in the production of international and domestic standard envelopes and flat bags. In addition to its high efficiency and stable functions, the specially designed trimming unit is capable of changing the standard and adjusting the size with speed and accuracy. The machine is thus suitable for mass production and small-batch jobs alike.
Major Structural Features
Using a suction method at the lower portion of the machine, blank paper that is laid on the feed plate is fed into machine. This method allows the pile of blanks to be replenished while the machine is operating, and no extra downtime. The paper orientation unit works with both convenience and accuracy. The lateral and longitudinal folding units help ensure the quality of the products, and a rotary glue application unit meets the requirements of any envelope or flat bag by gluing along straight tracks. Assisted by the suction cylinder, the folding unit works in a stable manner, and the graduated disc directly and accurately shows the adjusting volume. The collecting unit is equipped with electronic counting system and batching system.
