The unit covers the skills needed to undertake a web bonding process.

It applies to chemical, thermal, mechanical and latex bonding processes.

Work may be conducted in small to large scale enterprises and may involve individual and team activities.

The application of this unit is according to OHS practices of the enterprise and workplace practices, which may include:

requirements prescribed by legislation, awards, agreements and conditions of employment

standard operating procedures

work instructions

oral, written and visual communication

quality practices, including responsibility for maintenance of own work quality and contribution to quality improvement of team or section output

housekeeping

tasks related to environmental protection, waste disposal, pollution control, and recycling

This unit requires the application of skills associated with planning and organising for the safe and effective application of web bonding processes and technology. This unit also requires an ability to interpret and communicate job related information, check the quality of outcomes and identify and address problems relating to own work. Self management skills are applied to ensure workplace and quality standards are achieved.

Prerequisites

1.4 Machine controls are set to meet product requirements.

2 Undertake web bonding

2.1 Formed web supply and speed is checked for conformance to specification.

2.2 Web bonding process is monitored and operational parameters are adjusted to meet product requirements.

2.3 Machine operations are monitored to ensure safe and correct operation.

2.4 Minor product process and machine faults are identified and corrected where necessary to meet specified requirements and are reported.

2.5 Major machine faults are reported.

2.6 Machine is cleaned when required.

2.7 Machine is operated according to OHS practices.

3 Check bonded web quality

3.1 Bonded web is checked against quality standards and production requirements.

3.2 Bonded web faults and non-conformances are identified and rectified or reported.

4 Complete web bonding process

4.1 Bonded web is sent for web conversion and finishing or next manufacturing or packing process.

4.2 Cleaning of area is completed to ensure work environment is maintained in a safe and productive manner.

4.3 Production records are accurately completed.

Resource implications

Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and to information on workplace practices and OHS practices.

Context for assessment

Assessment may occur on the job or in an appropriately simulated environment.

Interdependent assessment

This unit may be assessed independently or in combination with other relevant units.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the Performance Criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.
