Safety of woodworking machines - Circular sawing machines - Part 8: Single blade edging circular rip sawing machines with power driven saw unit and manual loading and/or unloading

This European Standard deals with all significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to single blade edging circular rip sawing machines with power driven saw unit and manual loading and/or unloading, hereinafter referred to as "machines", designed to cut solid wood, chipboard, fibreboard and plywood when they are used as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse.
This European Standard applies to machines where the workpiece is stationary, the vertical and horizontal movements of the saw unit are power driven, and where the machine is provided with workpiece clamping. The workpiece may or may not be clamped during cutting.
This European Standard does not apply to machines:
-   where the workpiece is fed to the saw blade during cutting;
-   designed for cutting veneers;
-   provided with a device situated behind the line of cut, which moves in a direction parallel to the line of cut, for automatically unloading the workpiece during the return of the saw unit to the rest position.
This document is not applicable to machines manufactured before its date of publication as EN.

Sicherheit von Holzbearbeitungsmaschinen - Kreissägemaschinen - Teil 8: Einblattbesäum- und Leistenkreissägemaschinen mit kraftbetätigtem Sägeaggregat und Handbeschickung und/oder Handentnahme

Diese Europäische Norm behandelt alle im Abschnitt 4 aufgeführten signifikanten Gefährdungen, Gefährdungssituationen und Gefährdungsereignisse die auf Einblattbesäum- und Leistenkreissäge¬maschinen mit kraftbetätigtem Sägeaggregat und Handbeschickung und/oder Handentnahme zutreffen, im Folgenden als „Maschinen“ bezeichnet, die konstruiert sind zum Schneiden von Massivholz, Spanplatten, Faserplatten und Sperrholz, wenn sie bestimmungsgemäß und entsprechend den vom Hersteller vorgesehen Bedingungen einschließlich vernünftigerweise vorhersehbarer Fehlanwendung verwendet werden.
Dieses Dokument gilt für Maschinen, bei denen das Werkstück fest liegt, die senkrechten und waagrechten Bewegungen des Sägeaggregates kraftbetrieben sind, und wenn die Maschine mit einer Werkstückspanneinrichtung ausgerüstet ist. Das Werkstück kann während des Schnittes gespannt oder nicht gespannt sein.
Dieses Dokument gilt nicht für Maschinen:
-   bei denen während des Sägens das Werkstück zum Sägeblatt vorgeschoben wird;
-   die speziell für das Schneiden von Furnieren konstruiert sind;
-   die hinter der Schnittlinie mit einer Einrichtung ausgerüstet sind, die sich in einer Richtung parallel zur Schnittlinie bewegt, um dadurch während des Rücklaufs des Sägeaggregates in die Ruhestellung das Werkstück automatisch auszufördern.
Dieses Dokument gilt nicht für Maschinen, die vor dem Datum seiner Veröffentlichung als EN hergestellt werden.

Sécurité des machines pour le travail du bois - Machines à scies circulaires - Partie 8: Déligneuses mono-lames à déplacement mécanisé du groupe de sciage et à chargement et/ou déchargement manuel

La présente Norme européenne traite de tous les phénomènes dangereux, situations et événements dangereux significatifs, tels qu'énumérés à l'Article 4, applicables aux déligneuses mono-lames à déplacement mécanisé du groupe de sciage et à chargement et/ou déchargement manuel, (ci-après désignées "machines"), conçues pour la coupe de bois massif, de panneaux de particules et de fibres et de contreplaqué lorsqu’elles sont utilisées normalement et dans les conditions prévues par le fabricant, incluant une mauvaise utilisation raisonnablement prévisible.
La présente Norme européenne s'applique aux machines sur lesquelles la pièce à travailler est fixe, où les déplacements verticaux et horizontaux du groupe de sciage sont mécanisés et où la machine est munie d'un dispositif de bridage de la pièce.  La pièce peut ou non être bridée pendant la coupe.
La présente Norme européenne n'est pas applicable aux machines :
-   sur lesquelles la pièce est poussée vers la lame durant la coupe;
-   conçues  pour la coupe des feuilles de placage;
-   équipées d'un dispositif situé derrière la ligne de coupe, se déplaçant parallèlement à la ligne de coupe pour le déchargement automatique de la pièce pendant le retour du groupe de sciage à sa position de repos.
La présente Norme européenne est applicable avant tout aux machines fabriquées après la date de sa publication comme norme EN.

Varnost lesnoobdelovalnih strojev - Krožne žage - 8. del: Enolistne obrezovalne krožne žage s pogonsko enoto in ročnim dodajanjem in/ali odvzemanjem

Ta evropski standard opisuje vse večje nevarnosti, nevarne razmere in dogodke iz točke 4 v zvezi z enolistnimi obrezovalnimi krožnimi žagami s pogonsko enoto in ročnim podajanjem in/ali odvzemom (v nadaljevanju: »stroji«), ki so namenjeni rezanju polnega lesa, ivernih plošč, vlaknenih plošč in vezanih plošč ter se uporabljajo v skladu z namenom in pod pogoji, ki jih je predvidel proizvajalec, vključno z razumno predvideno nepravilno uporabo. Ta dokument se uporablja za naprave, kjer obdelovanec miruje, krožna žaga se navpično in vodoravno premika s pogonsko enoto, obdelovanec pa se lahko vpne v napravo. Med rezanjem se obdelovanec lahko vpne ali se ne vpne. Ta dokument se ne uporablja za naprave:
– kjer se obdelovanec med rezanjem podaja žagi;
– ki so izdelane za rezanje furnirja;
– ki imajo napravo za linijo rezanja, ki se premika paralelno z linijo rezanja, obdelovanec pa se med vračanjem žage v položaj mirovanja samodejno odvzema. Ta dokument se ne uporablja za stroje, ki so bili izdelani pred objavo standarda EN.
