Step-by-Step Process of Paper Bag Making

The operation of paper bag-making machines is quite simple, direct, and effortless. Let us look at the procedure step by step: 

• Step 1: Roll Paper Feeding

The initial stage of the operation of the device is paper roll feeding. Begins with a film unwinding gadget that unwinds the film in the form of rolls into the machine from a feeder role. The unwinded paper is taken straight into the feed chamber. The paper roll is being fed into the machine to produce paper bags. 

• Step 2: Paper Bag Forming

During this stage, the feeder rolls start to transfer the paper material into the formation stage, where the actual fabrication of the paper bag takes place.  The activity mainly involved in this stage is sealing. The paper material passes through the temperature regulated elements for a specific duration that provide an effective sealing to the film. Sealing time and the quantity of temperature of processing can be adjusted in the machine depending on the quality of the paper material. After the sealing, the materials pass through chiller units to bring down the temperature.

• Step 3: Cutting

With the completion of sealing, the materials then pass through the cutters with sharp blades which move upwards and downwards. The cutting step is the core of the manufacturing process because the design of the cutting segment largely determines the type of the machine.

• Step 4: Gluing

In the gluing stage, attaching and combining several cut pieces take place. The gluing compartment spreads the glue on the end portions of the paper bags in longitudinal and a transversal manner.

• Step 5: End Folding

At this step, the almost ready paper bag passes through a system of rollers which presses the paper bags to make them wholly in a single piece. The end sections of the bags also get folded. 

• Step 6: Finished Bag

Once the whole process ends, the bags get transferred to the stacker and then to the conveyor. The conveyor transmits the different pieces of paper bags to the ejection point from where one can pick them.

How simple and straightforward is the process, isn&#;t it? Purchasing this machine from top automatic machine manufacturers in India can only shower benefits onto your business goals. Hurry up, there isn&#;t time to waste! 

If you ever transported groceries from the store, or packed a lunch for work or school, chances are you&#;re familiar with Margaret Knight&#;s invention&#;the flat-bottomed paper bag. This was the most famous of several inventions that Knight patented at the end of the 19th century.

Margaret Eloise Knight was born on February 14th, in York, Maine. Her father died when she was young, which led the family to move to New Hampshire. Knight left school and began working in a cotton mill at only 12 years old in order to help her mother make ends meet. The cotton mill was a dangerous place for anyone in those days, especially a young girl, but it happens to be where Knight came up with her first invention. She saw other workers sustain injuries when using  some of the equipment, so she came up with a safety device that would protect workers from the hazardous conditions. Unfortunately, the pre-teen was not privy to the patenting process so she did not receive any compensation when her invention spread to other mills across the country.

In , Knight moved to Springfield, Massachusetts and began working at the Columbia Paper Bag Company. Just like at the cotton mill, Knight observed problematic operations at the paper bag company and she sought ways to make improvements through invention. In , she invented a machine that could quickly and efficiently fold and glue paper bags. The machine also gave the bags the iconic flat base that made packing items much easier. This time Knight knew she had to patent her invention, but she ran into trouble when Charles Annan, a man in the machine shop where Knight&#;s paper bag machine was being made, tried to steal the idea. Luckily, Knight had her original blueprints and was able to file a successful patent lawsuit, finally receiving a patent for her work in . A model of Knight&#;s machine can be found in the Smithsonian&#;s National Museum of American History.

Knight went on to cofound her own paper bag company in Hartford, Connecticut called the Eastern Paper Bag Company. Before her death in , she would patent over 25 inventions, ranging from machines for creating shoes, to a clasp for robes, to a window frame and sash. She is quoted as saying, &#;I&#;m only sorry I couldn&#;t have had as good a chance as a boy,&#; yet she was able to overcome many of the challenges and limits facing women inventors during her lifetime. Margaret E. Knight was inducted into the Inventors Hall of Fame in .
