SYSTEM FOR STRETCH-WRAPPING |
摘要 |
The invention provides a wrapping system for stretch-wrap plastic film. Plastic film (25) is partially pre-stretched by a selected amount and then relaxed prior to winding on a core (14). The film (25) is subsequently further stretched as it is drawn from the core (14) immediately prior to wrapping a load on a pallet, for example. The partial pre-stretching is preferably carried out in a number of steps by leading film (25) from a roll (10) over three rollers (15, 16, 17) in turn. These rollers (15, 16, 17) are driven at different speeds, the third roller (17) having a greater speed than the second roller (16) which in turn has a greater speed than the first roller (15). Thus, the film (25) is stretched in three steps prior to relaxing the film (25) and winding the relaxed film (25) on a core (14). The core (14) can be mounted on a hand-held dispenser which applies the final stretch to the film (25).
