摘要:
An article having non-planar portions, such as a pallet having a substantially flat deck member and a plurality of hollow leg members projecting integrally from the deck member, is molded as a one-piece unit from a loosely-felted, layered mat formed from a mixture of a resinous particle board binder and flake-like wood particles. The wood flakes have an average length of about 11/4 to about 6 inches, preferably about 2 to about 3 inches, an average thickness of about 0.005 to about 0.075 inch, preferably about 0.015 to about 0.025 inch, and an average width of 3 inches or less and no greater than the average length. Each layer of wood flakes in the mat lie substantially flat on a plane generally parallel to the major plane thereof and are randomly oriented to each other. The mat is placed between the male and female dies of a mold or press and compressed therein to substantially the desired shape under temperature and pressure conditions sufficient to bond the flakes together.

A pallet is a unitized structure formed from a mixture of lignocellulose-containing fibers and a thermosetting bonding agent which is subjected to heat and pressure. The unit structure has conical feet and crosspieces which have integrated stacking members to permit the pallets to be stakced without damage to the stacking members and without jamming.

An article, such as a pallet having a substantially flat deck member and a plurality of hollow legs projecting from the deck member, is molded as a one-piece unit from a papermill sludge. Dried, comminuted papermill sludge is blended with a fibrous reinforcing material, preferably a cellulosic material such as fibrous bark particles, and a resinous particle board binder, the resulting mixture of furnish is formed into a loosely fitted mat, and the mat is placed between dyes of a mold and press and compressed to substantially the desired shape under temperature and pressure conditions sufficient to bond the sludge and bark particles together.
摘要:
A throw-away loading pallet made from fibre board and having cardboard tubular supports serving as feet, the supports being interconnected by fibre board strips to strengthen them. The tubular supports at one end are secured to the pallet and at their opposite end to the connecting strips by sinking their ends in blind annular openings, with all contact surfaces being glued. The result is a light-weight cheap pallet of unusual strength, which can be recycled as waste pulp.
摘要:
A pallet made of composite material including thermo-setting plastic reinforced with fiberglass forming a platform with integral ribs molded to and extending downwardly from the platform and steel rods molded into the integral ribs at a distance from the section of neutral axis of the cross section of the pallet to make optimum use of the high tensile strength and modulus elasticity of steel, thus providing the required section modulus. The reinforced plastic face serves as the compression side of the beam and provides the required impact resistance from the flat loading surface.
摘要:
A one-piece, nestable, four-way molded pallet having a deck defining a load-supporting surface, a plurality of hollow pedestals formed integrally with the deck and a network of channels also formed integrally with the deck. The pedestals and channels depend downwardly from the deck to define depressions therein and are located in a preferred arrangement to provide maximum structural rigidity for the pallet.
摘要:
A modular pallet formed from a plurality of frame members and a plurality of deck members. The deck members extend between the frame members to define an upper deck surface and optionally a lower deck surface of the pallet. A plurality of spaced-apart channels are formed in at least an upper surface of the frame members to receive the deck members. In some embodiments the pallet may be configured as a stringer pallet and in other embodiments the pallet may be configured as a block pallet. In some embodiments the frame members are unitary stringers. In other embodiments the frame members are modular structures each comprising a block pallet subassembly and a deck support panel. The number, size, orientation and spacing of the channels formed in the frame members and the corresponding arrangement of the deck members may vary in different embodiments of the pallet. Once assembled, the frame members and deck members may be integrally connected, such as by heat welding. In some embodiments the pallet is formed from readily recyclable plastic.
