Unit of Competency LMTTX3020A - Identify and correct weaving process faults
Description This unit covers the skills and knowledge required to identify and correct product and weaving loom faults.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit applies to identifying and correcting weaving process problems in a textile operating environment. Discretion and judgement may be required, for both self and others, in planning and selecting processes, procedures or outcomes. Repairs are undertaken in accordance with established workplace procedures and practices and may include requirements recommended by manufacturers.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 employmentstandard operating procedureswork instructionsoral, written and visual communicationquality practices, including responsibility for maintenance of own work quality and contribution to quality improvement of team or section outputhousekeepingtasks related to environmental protection, waste disposal, pollution control and recyclingThis unit requires the application of skills associated with problem solving to identify faults and problems of equipment used in textile production. This unit also requires the ability to communicate information on equipment operations and production requirements.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Elements of Competency Performance Criteria              
Element: Gather relevant information
  • Pattern and production requirements are checked
  • Weaving operator is consulted on loom operation and on any operator identified faults
  • Loom operation and woven product is observed for faults
       
Element: Recognise and correct weaving faults
  • Weft faults are identified
  • Warp faults are identified
  • Selvedge faults are identified
  • General faults including incorrect creeling and other set up faults are identified
  • Cause of fault is determined and action taken in accordance with OHS practices
  • Any changes needed to be made in loom operation by the weaving operator are explained
       
Element: Maintain records
  • Records are maintained and reports prepared, where necessary
       


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

Critical aspects of evidence to be considered

Demonstrates skills and knowledge to:

identify and correct textile related weaving faults

apply problem solving techniques to resolve faults efficiently and effectively

apply workplace health and safety policies in work operations

maintain accurate records

Consistency in performance

Consistently applies skills and knowledge when:

organising work

completing tasks

identifying improvements

using workplace practices

using OHS practices

recording and reporting accidents and incidents

assessing operational readiness of equipment used and work processes

recognising and adapting to cultural differences in the workplace, including modes of behaviour and interactions

completing work systematically with attention to detail without damage to goods and equipment

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 should be assessed in conjunction withLMTTX3003B Set up and operate weaving looms for production

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This describes the essential skills and knowledge and their level, required for this unit.

Demonstrates knowledge of:

textile terms and definitions as they apply to weaving processes

fibres, yarns, fabrics and other textiles

weaving patterns and processes including yarn counts, sizing methods, yarn conditioning, fabric counts, design types, Sett construction, and warp tying methods

types of textile weaving faults

manufacturer's specifications for machine or equipment

OHS practices, including hazard identification and control measures

quality practices

workplace practices

recording and reporting practices

Demonstrates skills to:

operate a weaving loom

distinguish yarn counts

distinguish between types of weaves

recognise textile faults

read and follow a draft pattern

draw ends in correctly

read, interpret and follow information on work specifications, standard operating procedures and work instructions and other reference material

maintain accurate records

communicate within the workplace

sequence operations

meet specifications

clarify and check task-related information

carry our work according to OHS practices

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.

Legislative/regulatory requirements

All work must comply with relevant Federal and State or Territory legislative or regulatory requirements.

Looms may include

any machine typically used in the weaving sector concerned

microprocessor or computer controlled machines

both production and facility equipment used in the enterprise

Weaving faults may include

weft faults such as:

broken picks

OHS practices

OHS practices must include hazard identification and control, risk assessment and implementation of risk reduction measures specific to the tasks described by this unit, and may include:

manual handling techniques

standard operating procedures

personal protective equipment

safe materials handling

taking of rest breaks

ergonomic arrangement of workplaces

following marked walkways

safe storage of equipment

housekeeping

reporting accidents and incidents

other OHS practices relevant to the job and enterprise

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
