Abstract
An elongated, adhesively-coated, load-sustaining, supporting member attachable to a load for assisting in transporting the load from one location to another and to facilitate stacking of load units. The member is generally of a rectangular parallelepiped shape and has an elongated side completely covered with a hot-melt, pressure-sensitive adhesive for securing the member to the load. An easily removable sheet protecting the adhesive layer is applied to the entire adhesive area to protect the adhesive until time of use. The member may be cut to size, as appropriate, for a given dimensioned load.
Claims1
In combination, a load unit having generally flat top and bottom surfaces and adapted to be lifted and transported by load handling means, such as a fork lift truck, and capable of vertical stacking with similar load units, and a plurality of supporting and spacing members attached directly to the bottom surface only of said load unit in a spaced pattern to support the load unit from a supporting surface and support an upper load unit from a lower load unit when stacked vertically to enable insertion of the forks of a fork lift truck between the members and under the bottom surface of the load unit for direct contact therewith for lifting and transporting the load unit, each supporting and spacing member including an elongated block of rigid material having a lateral dimension substantially less than the lateral dimension of the bottom surface of the load unit and including parallel opposed top and bottom surfaces, and a continuous coating of adhesive material on the top surface for self-adhering the member permanently to the flat bottom surface of the load unit, said block of material being constructed of lightweight rigid foam plastic material capable of being cut to desired dimensional characteristics prior to installation and being substantially non-absorbent for retaining its strength characteristics when exposed to contact with water or moisture, each block being rectangular and having end edges substantially coinciding with opposed edges of the bottom surface of the load unit to which it is attached thereby forming projections on only the bottom surface of the load unit to which the supporting and spacing members are mounted, said adhesive material being a pressure-sensitive, hot-melt adhesive formulated from solid derivatives, and a strippable protective sheet for protecting the adhesive coating prior to mounting of each block on the load unit.
