Job Task Planning and Organizing

Rubber processing machine operators and related workers perform repetitive tasks daily. They determine the order and priority of work tasks based on customer orders and deadlines. They are interrupted frequently by customer calls and rush orders which may require work to be re-scheduled. Operators usually work on their own machines, although they co-ordinate their activities with co-workers. They plan what materials and machines will need to be used the next day and organize their workstations accordingly. (2)

Significant Use of Memory
  • Remember details of current jobs being produced so work sheets do not have to be continually referenced.
  • Remember preheat times for particular types of rubbers.
  • Remember correct procedures and settings for the wrapping of rolls, based on experience with different materials used.
Finding Information
  • Refer to catalogues and manuals or telephone suppliers directly to find out about particular products or pieces of equipment. (1)
  • Refer to WHMIS documents when using a new product to understand how to safely handle, store and dispose of it (1)
  • Seek help from co-workers on how to do certain work processes. (2)
  • Refer to a book of specifications and to different recipes when making rubber. (2)
  • When confronted with complex new jobs, refer to notes they have made about previous jobs to determine whether they are repeat jobs and what gearings and processes were used previously. (2)
Digital technology
  • Use other computer applications. For example, they may monitor variations in production quality by interpreting numerical readings on computer screens. They may enter new production parameters or codes into the computer in response to alarms or obvious production faults. (1)

Working with Others

Rubber processing machine operators usually work independently. Occasionally, when finishing rush orders, they may work alone. Rubber processing machine operators may work with partners, such as when keeping the tension of nylon high while the lathe spins, wrapping large rubber coated wheels with nylon. Work teams may be used to lift and move heavy objects. Some rubber processing machine operators are members of an assembly line team.

Continuous Learning

Rubber processing machine operators and related workers have an ongoing need to learn. For example, they may learn about new machines and materials by reading trade magazines and manuals, consulting senior operators, watching new processes or taking college machinist programs. They may be required to take courses relating to work health and safety.
