After testing the Shellfish Bag it showed a greater improvement that expected. The machine was calculated to put on 0.99 bag on the machine per second but after testing the machine actually put on 1.06 bags per second. The increase from 0.99 to 1.07 is due to the fact that the motor wasn't fully loaded causing it to rotate faster than the name plate RPM. The calculated output RPM was calculated to be 59 RPM and with the motor not fully loaded it was 63 RPM. The increase of 4 RPM just meant the material went on the machine faster. This wasn’t an issue it just helped improve the time factor of the machine.

 

With the material going on faster the next part was testing the cutting process. The cutting process on the current machine was 0.48 bags per second. The new machine had an average cutting time of 7.17 bags per second. This met the requirement of being able to cut 60 bags within 10 seconds. With the cutting time having such a large improvement it was necessary to compare the current and new machine to see the time saving it offered. By taking the average spool and cut time from figure 7, it was possible to do a 60 bag comparison. The comparison measure the amount of time it took to make 60 bags between the two machines. From the data of the current machine, would take 194 second while the new machine would take 65 seconds. The cut down in time meant that the new machine was 2.97 times faster than the old machine. With new machine being 2.97 times faster the testing was ended and the machine was given to the customer meeting his expectations.
