Abstract
An apparatus for applying stretch film to goods on a pallet. It uses a basic core holder to hold a roll of stretch film which has an adjustable braking mechanism. In addition, the apparatus, which is portable, is ergonomically correct, easy to use, and has a pair of pre-stretch rollers which allow the stretch film to be pulled to increase its elasticity, thereby securing goods effectively on a pallet.
Claims13
A manual handheld apparatus for applying stretch film around goods on a pallet, said apparatus comprising:
- a handle;
- a pair of end frames;
- an unheated stretch film core holder;
- and a first downstream pre-stretch roller and a second upstream pre-stretch roller;
- said pre-stretch rollers being in geared relationship with one another and rotating independently of said stretch film core holder;
- said first downstream pre-stretch roller rotating faster than said second upstream roller;
- said rollers being rotated in operation by tension exerted on said stretch film around goods on a pallet by an operator;
- said core holder being adapted to engage two ends of an elongated core having stretch wrap film wrapped there around;
- said core holder including an adjustable braking mechanism at a first top end;
- said adjustable braking mechanism including a tension knob with an earth magnet inserted therein at one end, remote from said stretch film;
- a large inset washer adapted to attract said earth magnet;
- an oblique slot containing at least three recesses;
- said recesses being adapted to receive a spring loaded ball bearing projecting inwardly in said knob;
- wherein in operation, manual rotation of said knob decreases or increases friction on said core holder;
- such that in operation, said stretch wrap is under tension during application around said goods on said pallet.
