本文件给出了最大工作宽度为350？mm、整体工件进给最大速度为200？m/min、可连续生产使用的四边成型机（以下简称“机器”）的安全要求和措施，该机器设计用于切割实木和具有类似木材物理特性的材料（见ISO 19085-1:2021，3.2）。 它处理附录A中列出的与机器相关的所有重大危险、危险情况和事件，当按照预期和制造商预见的条件进行操作、调整和维护时； 还考虑了合理可预见的滥用。此外，还考虑了运输、组装、拆卸、禁用和报废阶段。 它也适用于装有以下一个或多个装置/附加工作装置的机器，其危险已得到处理: -？通用主轴； -？玻璃珠锯装置； -？固定或移动工件支架； -？快速换刀系统； -？激光打标装置； -？自动工件回收器； -？进料斗内； -？装载弹匣； -？卸货台。 本文件不涉及与以下方面有关的任何危险: a） 除进料斗和装料库以外的进料装置； 注1:对于同样阻止进入进料口的机械进料装置，见6.6.4。 b） 除卸料台外的出料装置，因爬升切割而从机器中弹出的危险除外； c） 在进给速度大于60？m/min的机器上输出工件； 注？2？进给速度高于60？m/min的机器通常与机械卸载和工件转移系统相结合。 d） 与任何其他机器结合使用的机器（作为生产线的一部分）。 本标准不适用于在潜在爆炸性环境中使用的机器，也不适用于出版前制造的机器。

This document gives the safety requirements and measures for four-sided moulding machines, capable of continuous production use, with a maximum working width of 350？mm and a maximum speed of the integrated workpiece feed of 200？m/min, hereinafter referred to as “machines”, designed to cut solid wood and materials with similar physical characteristics to wood (see ISO 19085-1:2021, 3.2). It deals with all significant hazards, hazardous situations and events, listed in Annex？A, relevant to the machines, when operated, adjusted and maintained as intended and under the conditions foreseen by the manufacturer; reasonably foreseeable misuse has been considered too. Also, transport, assembly, dismantling, disabling and scrapping phases are taken into account. It is also applicable to machines fitted with one or more of the following devices / additional working units, whose hazards have been dealt with: —？universal spindle; —？glass bead saw unit; —？fixed or movable workpiece support; —？quick tool changing system; —？laser marking unit; —？automatic workpiece returner; —？in-feed hopper; —？loading magazine; —？unloading table. This document does not deal with any hazards related to: a) in-feed devices other than in-feed hopper and loading magazine; NOTE？1？For mechanical in-feed devices which also prevent access to the in-feed opening, see 6.6.4. b) out-feed devices other than unloading table, except for hazards related to ejection from the machine due to climb cutting; c) out-feed of workpieces on machines with feed speed higher than 60？m/min; NOTE？2？Machines with feed speed higher than 60？m/min are usually combined with mechanical unloading and workpiece transfer systems. d) machines being used in combination with any other machine (as part of a line). It is not applicable to machines intended for use in potentially explosive atmosphere and to machines manufactured prior to its publication.
