EN 415-6:2013 (E) 6 Introduction Pallet wrapping machines are used extensively in Europe, in an increasingly wide range of industries. They contain several significant hazards and have the potential to cause serious injury. Pallet wrapping machines fulfil the following major tasks: securing of palletised or unpalletised loads to prevent them collapsing and displacing during transport, handling, storage; pooling of loads and parts to form loads suitable for transport; protection against external influences; conditional protection against theft. This document is a type C standard as defined in the Introduction of EN ISO 12100:2010. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this standard.
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. SIST EN 415-6:2013
EN 415-6:2013 (E) 7
1 Scope This European Standard applies to the following groups of machines: pallet banding machines; stretch film pallet wrapping machines; stretch film hood application machines; mobile stretch film wrapping machines; semi automatic self driving stretch film wrapping machines; shrink film pallet wrapping machines; shrink film hood application machines; film removing machines; shrinking systems; sleeve wrapping machines for product greater than 400 mm in one direction; product centralising machines. The individual machines are described in 3.2.
This standard deals with safety requirements for machine design, construction, installation, commissioning, operation, adjustment, maintenance and cleaning of pallet wrapping machines. The extents to which hazards, hazardous situations and events are covered are indicated in Clause 4. Exclusions This European Standard is not applicable to the following machines: machines that were manufactured before the date of publication of this document by CEN; pallet strapping machines and destrapping machines. These machines are within the scope of EN 415-8; conveying systems that connect packaging machines with each other, but includes conveying systems that are part of the machines. This standard does not consider the following hazards: the use of pallet wrapping machines in potentially explosive atmospheres; the health, safety or hygiene hazards associated with the products that may be handled by the machines, but does include general advice on this subject; hazards that may be associated with electromagnetic emissions from pallet wrapping machines;
hazards that may be associated with decommissioning pallet wrapping machines. SIST EN 415-6:2013

3.1 Definition of terms 3.1.1 product article or articles, with or without pallet, that are handled in the pallet wrapping machine 3.1.2 pack assembly of product and packaging materials produced by a pallet wrapping machine 3.1.3 packaging material material used to secure a product, e.g. stretch film 3.1.4 flexible packaging material relatively thin paper, plastic film or flexible laminate 3.1.5 stretch film flexible elastic plastic film which can be pulled tightly around a product to form an envelope. It may stick to itself on contact or require heat sealing 3.1.6 stretch wrapping wrapping process in which the stretch film is stretched and wrapped around the product and sealed under tension 3.1.7 thermoplastic film, shrink film plastic film which shrinks when heated 3.1.8 film reel, packaging material reel continuous sheet of paper, plastic film, metal foil or flexible laminate wound on a cylindrical core 3.1.9 film clamp device to hold the film at the product for the first wrap. Also called film fixture SIST EN 415-6:2013
EN 415-6:2013 (E) 11 3.1.10 manual operation machine functions or modes where the only power source is directly applied manual effort 3.1.11 top sheet piece of packaging material which is applied to the top of the product e.g. to achieve water and dust protection 3.2 Description of pallet wrapping machines 3.2.1 General Pallet wrapping machines are machines listed in Clause 1 that secure product for transport and other purposes e.g. by applying packaging material or shrinking shrink film. Many of the machines deal with palletised products, therefore they are called, e.g.: pallet shrink wrapping machine, pallet shrink oven (see 3.12.3 of EN 415-1:2000+A1:2009). In many cases, however, machines can function without a pallet or with an alternative form of support for the pack.
3.2.2 Spiral stretch wrapping machines 3.2.2.1 General The stretching method uses film webs that are wound around product according to a given winding pattern (e.g. single or cross bracing). The number of the bottom windings or bottom edge windings or the degree of overlapping of the film webs can be variably adjusted. Stretch film wrapping machines wind a stretch film spirally around product, thus resulting in an envelope with horizontal and vertical tension forces. Pallet stretch wrapping machines include: Automatic stretch film wrapping machines: The machine is loaded and unloaded automatically by a conveyor. The application of the stretch film, stretching and cutting of the stretch film are done automatically. Semiautomatic stretch film wrapping machines: One or more of the following are done manually: loading or unloading of the machine, application or cutting of the stretch film. The wrapping movement is done automatically. Manual stretch film wrapping machines: Like semiautomatic stretch film wrapping machines, but additionally the movement of the lifting mechanism is done manually. The following types of stretch film wrapping machines exist. 3.2.2.2 Rotary table machine Product, which is positioned on a table that rotates, is wrapped. When used, vertically moveable film carriage and pre-stretching device are fitted to a column. The functional principle of a rotary table machine is shown in Figure 1. On manual rotary machine the vertical movement of the film carriage is done by an operator (see Figure 2). An example of a fully automatic rotary table machine is shown in Figure 3. The principle components are rotating table and film reel.
Optional assemblies: conveyors, film clamp, film knife, film sealing device, hold-down plate, pre-stretching unit on the film reel assembly, top sheet feeder. SIST EN 415-6:2013
