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 units4) lane deviation units5) perforating and welding or cutting and welding units6) blocking units7) pick-up and transfer units8) stacking units9) punching units10) folding units11 ) winding units12) labelling or taping units13) handle and closure units14) draw tape insertion units15) generators of electrostatic charge16) electrostatic discharge equipment.Printing units, high frequency welding machines and the design and construction of electrostatic generatorsare not covered by this standard.Ultrasonic radiation hazards resulting from ultrasonic welding devices, e.g. integrated in handle and closureunits, are not covered by this standard.Film converting machines for bags and sacks generally do not create explosive atmospheres. In principle theytherefore correspond with line F of Table 2 of the ATEX Guideline and consequently do not fall within thescope of Directive 94/9/EC.This document is not applicable to machines which are manufactured before the date of its publication as EN.【中国标准分类号】: G95【国际标准分类号】: 83_200【页数】: 34P.;A4【正文语种】: 英语 | 欢迎光临 世界资料网论坛 (http://bbs.infoeach.com/) | Powered by Discuz!
