EN 15067:2007 (E) 4 Foreword This document (EN 15067:2007) has been prepared by Technical Committee CEN/TC 145 “Plastics and rubber machines”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2008, and conflicting national standards shall be withdrawn at the latest by June 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directives. For relationship with EU Directives, see informative Annexes ZA and ZB, which are an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.



EN 15067:2007 (E) 5 Introduction This document is a type C standard as stated in EN ISO 12100-1.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard.



EN 15067:2007 (E) 6 1 Scope This European Standard specifies the safety requirements applicable to the design and construction of film converting machines for making bags and sacks, for the significant and specific hazards listed in Clause 4. This type of machine is based on the welding process. A film converting machine for bags and sacks starts at the film unwinding unit or at the film inlet when this machine is directly fed by an upstream process and ends at the product collection or delivery unit.
The bag making line may include: 1) unwind units 2) slit-welding units 3) gussetting units
4) lane deviation units
5) perforating and welding or cutting and welding units 6) blocking units 7) pick-up and transfer units 8) stacking units 9) punching units 10) folding units 11) winding units 12) labelling or taping units 13) handle and closure units 14) draw tape insertion units 15) generators of electrostatic charge 16) electrostatic discharge equipment. Printing units, high frequency welding machines and the design and construction of electrostatic generators are not covered by this standard. Ultrasonic radiation hazards resulting from ultrasonic welding devices, e.g. integrated in handle and closure units, are not covered by this standard. Film converting machines for bags and sacks generally do not create explosive atmospheres. In principle they therefore correspond with line F of Table 2 of the ATEX Guideline and consequently do not fall within the scope of Directive 94/9/EC. This document is not applicable to machines which are manufactured before the date of its publication as EN.
