Manufacture of plastic-fiber composition

Claim 1

THE METHOD OF MAKING MOLDABLE PREFORM MATERIAL CONTAINING HOT-MOLDABLE BINDER AND VEGETABLE FIBERS, WHICH COMPRISES CONTINUOUSLY DEPOSITING UPON A MOVING RECEIVING MEMBER FROM A GASEOUS SUSPENSION ENTITIES OF DRY FINELY DIVIDED SOLID HEAT-SOFTENABLE BINDER AND DRY SUBSTANTIALLY INDIVIDUALIZED VEGETABLE FIBERS AND THEREBY FORMING THEM INTO A LOOSE UNBONDED MAT HAVING A DENSITY NOT OVER 4 POUNDS PER CUBIC FOOT, SAID FIBERS AND BINDER BEING IN PROPORTION TO FORM A COLD RIGID BODY AFTER HOT-MOLDING AT SUBSTANTIALLY MAXIMUM COMPRESSION, SAID SOLID BINDER BEING NORMALLY NON-ADHESIVE AND CAPABLE OF SOFTENING TO A CONDITION ADHESIVE TO THE FIBER AT AN ELEVATED TEMPERATURE TO WHICH THE FIBERS MAY BE HEATED WITHOUT DESTRUCTION OF THEIR FIBROUS CHARACTER, AND BONDING THE FIBERS OF THE MAT TO FORM A STRUCTURE HAVING A DENSITY RANGING FROM SAID DENSITY OF FORMATION TO A DENSITY UP TO ABOUT 40 POUNDS PER CUBIC FOOT BY APPLYING HEAT AT A NONFUSING TEMPERATURE FOR THE BINDER AND OF INTENSITY TO EFFECT SURFACE-TACKINESS OF SAID BINDER, WHEREBY TO UNITE THE FIBERS ONE TO ANOTHER BY SAID INDIVIDUAL BINDER ENTITIES AND TO FIX THE MAJOR PORTION OF ALL THE ORIGINALLY SEPARATE ENTITIES OF THE ORIGINAL MAT INTO A RESULTINGLY STRENGTHENED BONDED MAT.

Claim 2

THE METHOD OF MAKING MOLDABLE PREFORM MATERIAL CONTAINING HOT-MOLDABLE BINDER AND VEGETABLE FIBERS, WHICH COMPRISES CONTINUOUSLY DEPOSITING UPON A MOVING RECEIVING MEMBER FROM A GASEOUS SUSPENSION ENTITIES OF DRY FINELY DIVIDED SOLID HEAT-SOFTENABLE BINDER AND DRY SUBSTANTIALLY INDIVIDUALIZED VEGETABLE FIBERS AND THEREBY FORMING THEM INTO A LOOSE UNBONDED MAT HAVING A DENSITY NOT OVER 4 POUNDS PER CUBIC FOOT, SAID FIBERS AND BINDER BEING IN PROPORTION TO FORM A COLD RIGID BODY AFTER HOT-MOLDING AT SUBSTANTIALLY MAXIMUM COMPRESSION, SAID SOLID BINDER BEING NORMALLY NON-ADHESIVE AND CAPABLE OF SOFTENING TO A CONDITION ADHESIVE TO THE FIBER AT AN ELEVATED TEMPERATURE TO WHICH THE FIBERS MAY BE HEATED WITHOUT DESTRUCTION OF THEIR FIBROUS CHARACTER, AND BONDING THE FIBERS OF THE MAT TO FORM A STRUCTURE HAVING A DENSITY RANGING FROM SAID DENSITY OF FORMATION TO A DENSITY UP TO ABOUT 40 POUNDS PER CUBIC FOOT BY APPLYING HEAT AT A NONFUSING TEMPERATURE FOR THE BINDER AND OF INTENSITY TO EFFECT SURFACE-TACKINESS OF SAID BINDER, WHEREBY TO UNITE THE FIBERS ONE TO ANOTHER BY SAID INDIVIDUAL BINDER ENTITIES AND TO FIX THE MAJOR PORTION OF ALL THE ORIGINALLY SEPARATE ENTITIES OF THE ORIGINAL MAT INTO A RESULTINGLY STRENGTHENED BONDED MAT.
