Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
119 words
A lift truck pallet comprising in combination: (a) a plurality of elongated narrow stringers arranged in parallel, spaced relationship; (b) a plurality of elongated narrow runners arranged in parallel, spaced relation, substantially at right angles to the stringers so as to form the perimeter of a plurality of comparatively broad open spaces; (c) spacer means defining lift truck fork openings in the sides of the pallet; (d) fastening means securing the stringers and runners together; and (e) said broad open spaces being tautly overwrapped with a plurality of layers of stretch wrap film in its tension-stretched condition, so as to form in cooperation with said stringers and runners, plastic film product-supporting surfaces for said open spaces of said pallet.
Claim 2
Dependent Claim
119 words
A lift truck pallet comprising in combination: (a) a plurality of elongated narrow stringers arranged in parallel, spaced relationship; (b) a plurality of elongated narrow runners arranged in parallel, spaced relation, substantially at right angles to the stringers so as to form the perimeter of a plurality of comparatively broad open spaces; (c) spacer means defining lift truck fork openings in the sides of the pallet; (d) fastening means securing the stringers and runners together; and (e) said broad open spaces being tautly overwrapped with a plurality of layers of stretch wrap film in its tension-stretched condition, so as to form in cooperation with said stringers and runners, plastic film product-supporting surfaces for said open spaces of said pallet.
Claim 3
Dependent Claim
28 words
The pallet of claim 1 wherein said layers are cross-wrapped to yield a pallet having a plurality of plastic film product-supporting surfaces at right angles to one another.
Claim 4
Dependent Claim
19 words
The pallet of claim 1 wherein the several layers of film are continuous and include some diagonal change-of-direction layers.
Claim 5
Dependent Claim
14 words
The pallet of claim 1 wherein two or more layers cover said open spaces.
Claim 6
Dependent Claim
13 words
The pallet of claim 4 wherein said open spaces are rectangular in shape.
Claim 7
Dependent Claim
21 words
The pallet of claim 4 wherein said plastic film layer is continuous from one rectangle to the next to be covered.
Claim 8
Dependent Claim
122 words
A process for preparing a lift truck pallet comprising: (a) arranging a plurality of elongated narrow stringers in parallel, spaced relation; (b) arranging a plurality of elongated narrow runners in parallel, spaced relation substantially at right angles to said stringers so as to form the perimeter of a plurality of comparatively broad rectangles; (c) providing spacer means defining lift truck fork openings in the sides of the pallet; (d) fastening said stringers and runners together; and (e) tautly overwrapping said plurality of comparatively broad open spaces framed by said stringers and runners with a plurality of layers of stretch wrap film by applying braking tension to said film so as to stretch the film and while stretched affixing it to the structure.
Claim 9
Dependent Claim
122 words
A process for preparing a lift truck pallet comprising: (a) arranging a plurality of elongated narrow stringers in parallel, spaced relation; (b) arranging a plurality of elongated narrow runners in parallel, spaced relation substantially at right angles to said stringers so as to form the perimeter of a plurality of comparatively broad rectangles; (c) providing spacer means defining lift truck fork openings in the sides of the pallet; (d) fastening said stringers and runners together; and (e) tautly overwrapping said plurality of comparatively broad open spaces framed by said stringers and runners with a plurality of layers of stretch wrap film by applying braking tension to said film so as to stretch the film and while stretched affixing it to the structure.
Claim 10
Dependent Claim
12 words
The process of claim 7 wherein said overwrapping includes some cross overwrapping.
Claim 11
Dependent Claim
14 words
The process of claim 7 wherein said stretch wrap film is a polyolefin film.
