NZQA Expiring unit standard 3784 version 6 Page 1 of 4 Title Produce fault free single face web during paper changes for fibreboard manufacture Level 4 Credits 24 Purpose People credited with this unit standard will be able to: make paper changes of differing papers with minimal waste whether or not the paper grade changes; make paper changes of differing papers with minimal delays to production; and take preparatory actions to minimise the risk of faults or production delays occurring during changes of paper grade and/or width. Classification Fibreboard Packaging > Fibreboard Manufacture Available grade Achieved Entry information Critical health and safety prerequisites Unit 340, Demonstrate knowledge of safe working practices in the printing and graphic pre-press industries, or demonstrate equivalent knowledge and skills. Recommended skills and knowledge Unit 3761, Change reels on a corrugator in the fibreboard packaging industry; and Unit 21620, Correct faults in a single face web for fibreboard manufacture; or demonstrate equivalent knowledge and skills. Explanatory notes 1 All workplace practices must meet any applicable and recognised codes of practice, and documented workplace health, safety, and environmental procedures for personal, product, workplace health, safety, and environmental matters, and the obligations required under current law including the Health and Safety in Employment Act 1992, Hazardous Substances and New Organisms Act 1996, Resource Management Act 1991, Privacy Act 1993 and their subsequent amendments. 2 Workplace practices refer to the documented procedures for the machine and/or workplace. 3 Dual arch is excluded from in this unit standard. 4 Where referred to, ‘plant listed maximum speed’ is that determined by each workplace as appropriate for the board dimensions, board type and run length in production. Competenz SSB Code 101571 New Zealand Qualifications Authority 2016 NZQA Expiring unit standard 5 3784 version 6 Page 2 of 4 Faults in this unit standard are defined as: misalignment of liner and medium papers exceeding 5mm at operator side, any delamination of the single face web whether extensive or localised, any form of fractured or damaged flutes in the web, any damage to the top liner paper occurring between the single facer and the double backer. Outcomes and evidence requirements Outcome 1 Make paper changes of differing papers with minimal waste whether or not the paper grade changes. Evidence requirements 1.1 Reels are loaded and splices made without any paper breaks in accordance with workplace practices. 1.2 Paper changes from wider to narrower widths, whether of similar or different grades, are made without creating excess faulty web. Range loose web corrugators, not more than 20 lineal metres of faulty web; tight web corrugators, not more than 50 lineal metres of faulty web. 1.3 Paper changes from narrower to wider widths, whether of similar or different grades, are made without creating more than 50 lineal metres of faulty web. 1.4 Paper changes involving no change of width but a change of grade are made without creating excess faulty web. Range loose web corrugators, not more than 5 lineal metres of faulty web; tight web corrugators, not more than 15 lineal metres of faulty web. Outcome 2 Make paper changes of differing papers with minimal delays to production. Evidence requirements 2.1 On loose web corrugators, paper changes involving no change of width but a change of grade are made without causing the double backer and platen section to reduce speed below 50% of plant listed maximum. 2.2 On loose web corrugators, paper changes from wider to narrower widths where the change in width is 150mm or less are made without causing the double backer and platen section to reduce speed below 50% of plant listed maximum, whether or not the paper grade changes.

Outcome 3 Take preparatory actions to minimise the risk of faults or production delays occurring during paper changes of grade and/or width. Evidence requirements 3.1 Situations at paper changes likely to cause faults in the web or production delays are explained in terms of workplace practices and equipment configuration. 3.2 Actions available to minimise the risk of faults or production delays at paper changes are explained in terms of workplace practices and equipment configuration. 3.3 Proactive measures available in the workplace are taken by adjusting equipment settings to minimise the risk of faults and delays at paper changes.

Please note Providers must be granted consent to assess against standards (accredited) by NZQA, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment. Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards. Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards. Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMR). The CMR also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
