3 Terms and definitions
For the purposes of this document the terms and definitions given in Clause 3 of EN ISO 12100:2010, and EN 415-1:2000+A1:2009 and the following apply. 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  3.1.10 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 automatially. 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 aditionally the movement of the lifting mechanism is done manually. 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, flim clamp, film knife, fim sealing device, hold-down plate, pre-stretching unit on the film reel assembly, top sheet feeder. 3.2.2.3 Rotary arm machine Machine which wraps product in film or net, from a reel on an arm which rotates around the stationary product (see Figure 4 and Figure 5). . The principle components are: rotating arm, film reel assembly and lifting mechanism which moves the arm up and down.
