Abstract
Methods for producing a chipped wood surfacing material having unusually high shock absorbing capabilities are provided. The chipped wood is processed in order to give it a very high shock absorbing quality. This invention also relates to chipped wood having these unusually high shock absorbing characteristics.
Claims17
A method of manufacturing a chipped wood surfacing material, comprising the steps of:
- processing poles of the Family Salicaceae, genus Populus through a knife type chipper to from wood chips comprising a plurality of wood fibers;
- shredding said wood chips under conditions sufficient to loosen but not separate the bonding between said fibers in said chips and to entrap extrinsic air between said wood fibers;
- and
- passing said wood chips through a screen with a pore size of about one inch in diameter to form a plurality of wood particles having, in aggregate, a critical height of at least 8 feet at an uncompressed depth of 6 inches at any outdoor temperature.
Chipped wood surfacing material generated by the method comprising the steps of:
- harvesting trees of the Family Salicaceae, genus Populus;
- de-limbing said trees to form poles;
- processing said poles through a knife type chipper to form wood chips comprising a plurality of wood fibers;
- shredding said wood chips under conditions sufficient to loosen but not separate the bonding between said fibers in said chips and to entrap extrinsic air between said wood fibers;
- and
- passing said wood chips through a screen with a pore size of about one inch in diameter to form a plurality of wood particles having, in aggregate, a critical height of at least 8 feet at an uncompressed depth of 6 inches at any outdoor temperature.
Chipped wood surfacing material comprising chipped wood of the genus Populus, said chipped wood having loosened but not separated wood fibers and having extrinsic air trapped between said fibers, said chipped wood surfacing material having a critical height of at least 8 feet at any outdoor temperature.
