Advantages 5. Limitations 6. Length 7. Number of Cycles to be Timed. Definition of Time Study: Time study may be defined as “the art of observing and recording the time required to do each detailed element of an industrial activity/operation.” The term industrial activity includes mental, manual and machining operation, where:   (i) Mental time includes time taken by the operator for thinking over some alternative operations. (ii) Manual time consists of three types of operations i.e. related with handling of materials, handling of tools and handling of machines. (iii) Machining time includes time taken by the machines in performing the requisite operations. Thus time study standardizes the time taken by average worker to perform these operations. Objectives of Time Study: The main objectives o...

How Many PPE Coveralls Can be Made by One Hot Air Seam Sealing Machine? Body Coverall The essential operations in a body coveralls making is heat sealing operations of all seam lines.  Whoever is making or planning to manufacture PPE body coveralls for medical use has all other sewing machines in enough numbers. The bottleneck is a hot air seam sealing one. So a factory's daily body coveralls production depends on hot air seam sealing machines. Here, I have shared the productivity (production capacity) of the hot air seam sealing machine.   To answer this question, I will refer 3 sources  - In a webinar, Dr. K.S. Sundararaman said that PPE coverall manufacturers can make 12-13 body coveralls per hour.  That means you can make 96-100 coveralls in an eight-hour shift. For more information listen to the webinar audio record here.  - Another source has mentioned that a seam sealing machine can produce 10 body coveralls per hour and 80 coveralls in an eight-hour shift.     - Referring t...
