Bibliography

This European Standard contains the safety requirements for the design and construction of haul-offs used in extrusion lines for processing plastics and rubber for the hazards identified in clause 4. The following kinds of haul-offs are covered:-caterpillar haul-offs;-belt haul-offs;-capstan haul-offs;-belt capstan haul-offs;-roller haul-offs.The machine begins at the material inlet opening and ends at the material outlet.Cutting units which are integrated with or attached to the haul-off are not covered.Take-off devices used at film or sheet lines are not covered.Chemical, toxicological and fire hazards which could occur for example in continuous vulcanisation plants due to the materials processed are not dealt with.Unwinding and winding machines are not subject to this standard. They are being dealt with in a separate standard being produced by another working group of CEN/TC 145.This document is not applicable to haul-offs which are manufactured before the date of publication by CEN of this document.
