NF EN 12750

Le présent document, préparé dans le but de donner des moyens de se conformer aux exigences des Directives "Machines" 98/37/CEE et 2006/42/CE. Il détermine les prescriptions de sécurité des machines à moulurer sur quatre faces.

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.
